WEBVTT 00:00:00.000 --> 00:00:04.240 Let's unpack this. We are diving deep today into 00:00:04.240 --> 00:00:07.080 one of the most powerful and often misunderstood 00:00:07.080 --> 00:00:10.740 concepts in all of economics, opportunity cost. 00:00:10.980 --> 00:00:14.019 It's the true sort of hidden price tag that's 00:00:14.019 --> 00:00:16.300 attached to every single decision you make. Every 00:00:16.300 --> 00:00:18.019 single one. It doesn't matter if you're running 00:00:18.019 --> 00:00:20.359 a Fortune 500 company or, like you said, just 00:00:20.359 --> 00:00:22.539 deciding what to have for dinner. It's always 00:00:22.539 --> 00:00:25.179 there. Right. Because when most of us talk about 00:00:25.179 --> 00:00:27.199 cost, we're really just focusing on the explicit 00:00:27.199 --> 00:00:29.940 price, the actual cash that leaves our wallet. 00:00:30.120 --> 00:00:32.859 But the economic reality of limited resources 00:00:32.859 --> 00:00:36.420 dictates that every choice by necessity involves 00:00:36.420 --> 00:00:39.479 a sacrifice. It has to. Our sources today, and 00:00:39.479 --> 00:00:41.079 we've looked at everything from foundational 00:00:41.079 --> 00:00:44.579 microeconomic texts to contemporary articles 00:00:44.579 --> 00:00:46.939 on global trade and even health policy, they 00:00:46.939 --> 00:00:49.619 all emphasize the same fundamental idea. And 00:00:49.619 --> 00:00:52.250 what is that idea? That given scarce resources, 00:00:52.490 --> 00:00:54.570 when you choose one alternative, you are actively, 00:00:54.770 --> 00:00:57.189 by definition, losing the benefit of the other 00:00:57.189 --> 00:01:00.009 options you didn't choose. So opportunity cost 00:01:00.009 --> 00:01:02.329 is formally defined as the value of the best 00:01:02.329 --> 00:01:04.650 alternative foregone when a choice is made between 00:01:04.650 --> 00:01:08.250 several options. And that framing is so crucial. 00:01:08.409 --> 00:01:10.409 It really is. It's where a lot of people stumble 00:01:10.409 --> 00:01:14.590 at first. How so? Well, if we assume, as economists 00:01:14.590 --> 00:01:18.290 generally do, that you're a rational actor trying 00:01:18.290 --> 00:01:20.890 to make the optimal choice. The one that gives 00:01:20.890 --> 00:01:24.370 you the most benefit or utility. Exactly. Then 00:01:24.370 --> 00:01:26.689 the opportunity cost isn't the cost of all the 00:01:26.689 --> 00:01:28.750 other choices combined. It's the cost you incur 00:01:28.750 --> 00:01:32.329 by not enjoying the benefit that was available 00:01:32.329 --> 00:01:34.709 from your second best choice. Right. So it's 00:01:34.709 --> 00:01:37.170 not the cost of everything else, just the value 00:01:37.170 --> 00:01:39.769 of the single most attractive alternative that 00:01:39.769 --> 00:01:42.209 you had to walk away from. Precisely. So if I 00:01:42.209 --> 00:01:44.629 have, say, an hour of free time and I can either 00:01:44.629 --> 00:01:47.069 read a book, which is option A, go for a run, 00:01:47.129 --> 00:01:50.569 option B, or clean the garage, option C. And 00:01:50.569 --> 00:01:52.209 let's be honest, cleaning the garage is probably 00:01:52.209 --> 00:01:55.400 option C for most of us. Right. So let's say 00:01:55.400 --> 00:01:57.040 reading the book gives me the highest utility. 00:01:57.280 --> 00:02:00.120 I value that the most. But going for a run was 00:02:00.120 --> 00:02:02.760 the next best thing. Then the opportunity cost 00:02:02.760 --> 00:02:04.640 of me reading that book is the health benefit 00:02:04.640 --> 00:02:07.079 and the stress relief I lost by not going for 00:02:07.079 --> 00:02:10.060 that run. Exactly. And that brings us right to 00:02:10.060 --> 00:02:13.580 the core issue of scarcity. The moment resources 00:02:13.580 --> 00:02:16.960 are limited and all resources, including our 00:02:16.960 --> 00:02:19.560 time, are limited, you are forced to choose. 00:02:19.930 --> 00:02:21.770 There's no way around it. And the whole point 00:02:21.770 --> 00:02:24.449 of calculating opportunity costs then is efficiency. 00:02:24.930 --> 00:02:27.430 Purely efficiency. Whether it's in a massive 00:02:27.430 --> 00:02:30.030 corporation or just in your own home, it's a 00:02:30.030 --> 00:02:33.629 mechanism. It's a tool to ensure the most efficient 00:02:33.629 --> 00:02:35.990 allocation and use of those scarce resources. 00:02:36.409 --> 00:02:38.810 Because if you pick option A, but the benefit 00:02:38.810 --> 00:02:41.719 you lost from option B was actually higher. You've 00:02:41.719 --> 00:02:43.319 made a bad trade. You've made an inefficient 00:02:43.319 --> 00:02:46.000 choice. The cost was too high. And we really 00:02:46.000 --> 00:02:48.840 have to underscore this point right now. Opportunity 00:02:48.840 --> 00:02:50.819 costs are not just about money. They are not 00:02:50.819 --> 00:02:53.340 restricted to monetary or financial costs. We're 00:02:53.340 --> 00:02:55.960 talking about all associated costs. Absolutely. 00:02:56.120 --> 00:02:58.199 I mean, this is the fundamental difference between 00:02:58.199 --> 00:03:00.740 simple bookkeeping and true economic analysis. 00:03:01.000 --> 00:03:03.500 We're talking about explicit costs, the cash 00:03:03.500 --> 00:03:06.060 that actually moves, but also implicit costs. 00:03:06.300 --> 00:03:09.240 And that's the tricky part. It is. Because implicit 00:03:09.240 --> 00:03:12.840 costs cover things like lost time, lost pleasure, 00:03:13.020 --> 00:03:16.699 lost potential income, or any other non -monetary 00:03:16.699 --> 00:03:19.319 benefit that provides you with utility. The fact 00:03:19.319 --> 00:03:22.240 that opportunity cost lets us quantify these 00:03:22.240 --> 00:03:24.879 intangible tradeoffs, that's what makes it so 00:03:24.879 --> 00:03:27.379 vital, isn't it? That's the power. It gives you 00:03:27.379 --> 00:03:29.759 a comprehensive metric of the true sacrifice 00:03:29.759 --> 00:03:32.180 involved in any decision you make. And if we 00:03:32.180 --> 00:03:34.240 really start thinking this way... Everything 00:03:34.240 --> 00:03:38.020 changes. Choosing to spend an hour on, say, professional 00:03:38.020 --> 00:03:40.580 development instead of high -value client work, 00:03:40.740 --> 00:03:44.389 that incurs an implicit cost. A huge one. It's 00:03:44.389 --> 00:03:46.430 based on the income you just lost. Or if you 00:03:46.430 --> 00:03:48.289 choose a long commute to live in a bigger house, 00:03:48.430 --> 00:03:51.229 the explicit cost is the gas for your car. Sure, 00:03:51.250 --> 00:03:53.430 that's easy to see. But the implicit cost is 00:03:53.430 --> 00:03:56.069 the two extra hours of free time you lose every 00:03:56.069 --> 00:03:58.349 single day that you can never get back. And those 00:03:58.349 --> 00:04:00.789 implicit costs often compound over time, which 00:04:00.789 --> 00:04:03.330 can make them far, far more significant than 00:04:03.330 --> 00:04:05.930 whatever initial cash you laid out. To truly 00:04:05.930 --> 00:04:08.550 calculate if a decision is sound economically, 00:04:09.129 --> 00:04:11.930 you have to recognize the anatomy of cost itself. 00:04:12.569 --> 00:04:15.349 Okay, so let's break down that anatomy now. Let's 00:04:15.349 --> 00:04:17.970 move beyond just the definition and into our 00:04:17.970 --> 00:04:21.529 first segment, the dual nature of costs explicit 00:04:21.529 --> 00:04:24.990 versus implicit. Sounds good. Let's start with 00:04:24.990 --> 00:04:27.189 the one that's easier to grasp. The one that, 00:04:27.209 --> 00:04:29.810 you know, gives accountants peace of mind. We 00:04:29.810 --> 00:04:32.569 can start with the explicit costs. And they are, 00:04:32.649 --> 00:04:35.129 as you say, straightforward. These are the direct, 00:04:35.290 --> 00:04:37.730 out -of -pocket costs of any action. Is it tangible? 00:04:38.050 --> 00:04:40.790 Always. They always involve a dollar value or 00:04:40.790 --> 00:04:43.269 some clear transfer of money. These are the costs 00:04:43.269 --> 00:04:45.410 you can spot immediately on an income statement. 00:04:45.529 --> 00:04:48.170 Things like operational expenses, wages, rent, 00:04:48.430 --> 00:04:51.629 overhead, utilities, raw materials. Right. They're 00:04:51.629 --> 00:04:53.540 the costs that hit the company's... bank account 00:04:53.540 --> 00:04:56.480 directly. They're simple because they're transactional. 00:04:56.519 --> 00:04:58.439 You have a receipt for them. So let's use that 00:04:58.439 --> 00:05:01.060 scenario from our sources. Imagine an employee 00:05:01.060 --> 00:05:04.399 leaves work for one hour to buy, say, $200 worth 00:05:04.399 --> 00:05:07.300 of office supplies. Okay. The explicit cost here 00:05:07.300 --> 00:05:10.199 is totally transparent. It's the $200 cash spent 00:05:10.199 --> 00:05:12.220 on the supplies. Right. And maybe you could add 00:05:12.220 --> 00:05:14.500 the explicit cost of the gas needed for the trip. 00:05:14.839 --> 00:05:17.139 But it's a recorded cash outflow. You can track 00:05:17.139 --> 00:05:19.639 it. Or another one, a classic business headache, 00:05:19.879 --> 00:05:24.139 a malfunctioning printer. The explicit cost is 00:05:24.139 --> 00:05:26.339 just the total amount you pay directly to the 00:05:26.339 --> 00:05:28.500 repair technician for their parts and labor. 00:05:28.699 --> 00:05:30.779 You can point to the invoice and say that is 00:05:30.779 --> 00:05:33.980 the cost. And that is precisely why standard 00:05:33.980 --> 00:05:37.339 accounting practices love explicit costs. They're 00:05:37.339 --> 00:05:39.540 verifiable. They're easily auditable. And they 00:05:39.540 --> 00:05:42.220 provide a clear fiscal record of the firm's cash 00:05:42.220 --> 00:05:45.120 flows for reporting. But, and this is a huge 00:05:45.120 --> 00:05:48.879 but, relying only on those explicit costs. gives 00:05:48.879 --> 00:05:51.620 you an incomplete picture. And often it's a dangerously 00:05:51.620 --> 00:05:54.220 optimistic picture of the economic reality. Because 00:05:54.220 --> 00:05:56.579 to understand the true cost of that choice, we 00:05:56.579 --> 00:05:58.639 have to flip the coin over and look at the implicit 00:05:58.639 --> 00:06:00.720 side. This is where the economist steps in, right? 00:06:00.819 --> 00:06:03.019 Exactly. And what's so fascinating here is how 00:06:03.019 --> 00:06:05.560 these implicit costs, which are also sometimes 00:06:05.560 --> 00:06:08.519 called imputed or implied or even notional costs, 00:06:08.720 --> 00:06:11.639 are often hidden in plain sight. Okay, so define 00:06:11.639 --> 00:06:14.199 it for us. What is an implicit cost? By definition, 00:06:14.339 --> 00:06:18.300 an implicit cost is the opportunity cost of using 00:06:18.300 --> 00:06:21.420 resources that are owned by the firm or the individual. 00:06:22.279 --> 00:06:24.959 Resources that could have been used for other 00:06:24.959 --> 00:06:28.160 profitable or utility generating purposes. So 00:06:28.160 --> 00:06:30.439 the moment you call them notional, you're stepping 00:06:30.439 --> 00:06:34.000 away from something tangible. You are. Since 00:06:34.000 --> 00:06:36.560 these costs don't involve an immediate cash exchange, 00:06:36.899 --> 00:06:39.600 they've already occurred within a project without 00:06:39.600 --> 00:06:42.500 a transaction. And for that reason, they're generally 00:06:42.500 --> 00:06:44.199 not recorded for standard accounting purposes. 00:06:44.319 --> 00:06:46.740 Because there's no cash flow. No cash flow. But 00:06:46.740 --> 00:06:49.060 they represent a significant loss of potential 00:06:49.060 --> 00:06:51.139 value. What are some of the primary examples? 00:06:51.579 --> 00:06:53.560 The biggest ones usually center on resources 00:06:53.560 --> 00:06:55.959 contributed by a business owner. Their own time, 00:06:56.060 --> 00:06:58.620 their own labor, the use of their personal infrastructure. 00:06:58.899 --> 00:07:00.879 Like using their own car for deliveries. Exactly. 00:07:00.920 --> 00:07:03.319 Or the implicit cost of the risk they're personally 00:07:03.319 --> 00:07:05.939 bearing. And a critical component is just the 00:07:05.939 --> 00:07:08.829 time spent. Every single moment you invest in 00:07:08.829 --> 00:07:11.170 one activity is a valuable activity for Gone. 00:07:11.769 --> 00:07:14.290 We also have to include the depreciation of owned 00:07:14.290 --> 00:07:17.930 goods, materials, and equipment. How is depreciation 00:07:17.930 --> 00:07:21.209 an implicit cost? Because the asset loses value 00:07:21.209 --> 00:07:24.269 over time. That's a hidden cost of using it for 00:07:24.269 --> 00:07:26.709 Project A instead of, say, selling it when its 00:07:26.709 --> 00:07:29.110 value was higher. Got it. Okay, let's go back 00:07:29.110 --> 00:07:30.930 to our scenarios and add this layer of complexity. 00:07:32.110 --> 00:07:34.529 Take the employee who left work for an hour to 00:07:34.529 --> 00:07:38.649 spend $200 on supplies. The $200 was the explicit 00:07:38.649 --> 00:07:41.790 cost. Right. Now, what if that employee's hourly 00:07:41.790 --> 00:07:44.829 rate is $25 and that hour could have been spent 00:07:44.829 --> 00:07:47.389 on billable client work? Now we're getting to 00:07:47.389 --> 00:07:49.889 it. The implicit cost of spending that hour buying 00:07:49.889 --> 00:07:52.810 supplies is the $25 in potential earnings that 00:07:52.810 --> 00:07:55.649 they sacrificed. That $25 is the opportunity 00:07:55.649 --> 00:07:58.579 cost of that hour of labor. The company didn't 00:07:58.579 --> 00:08:01.120 write a check for $25 to the ghost of lost productivity, 00:08:01.360 --> 00:08:04.300 but that potential revenue is gone forever. It's 00:08:04.300 --> 00:08:06.800 a real economic loss. And what about the malfunctioning 00:08:06.800 --> 00:08:08.860 printer? The explicit cost was the repair bill. 00:08:08.980 --> 00:08:11.019 Sure. The implicit cost, though, is much harder 00:08:11.019 --> 00:08:13.120 to measure, but it's often much, much higher. 00:08:13.199 --> 00:08:14.939 It's the total production time that was lost. 00:08:15.879 --> 00:08:18.839 If that printer serves a manufacturing line that 00:08:18.839 --> 00:08:21.540 usually processes, say, $1 ,000 worth of output 00:08:21.540 --> 00:08:24.439 every hour, and it's down for four hours. Then 00:08:24.439 --> 00:08:28.199 the implicit cost is $4 ,000 worth of foregone 00:08:28.199 --> 00:08:30.899 marginal revenue. It dwarfs the repair bill. 00:08:31.310 --> 00:08:34.009 The classic, really relatable anecdote here is 00:08:34.009 --> 00:08:36.289 the small business owner. Oh, this is the perfect 00:08:36.289 --> 00:08:38.750 example. In the early years, they often pour 00:08:38.750 --> 00:08:41.850 thousands of hours into their new venture. They 00:08:41.850 --> 00:08:44.690 forego a regular high -end salary, and maybe 00:08:44.690 --> 00:08:47.049 they even use their own basement or garage as 00:08:47.049 --> 00:08:50.210 office space. Right. That foregone salary, the 00:08:50.210 --> 00:08:52.090 income they could have earned working for someone 00:08:52.090 --> 00:08:55.500 else, is the implicit cost of their labor. And 00:08:55.500 --> 00:08:57.240 the rent they could have charged someone else 00:08:57.240 --> 00:08:59.799 for the use of their space is the implicit cost 00:08:59.799 --> 00:09:02.320 of their own infrastructure. Exactly. And if 00:09:02.320 --> 00:09:04.659 they ignore those implicit costs, their business 00:09:04.659 --> 00:09:07.100 looks highly profitable on paper. Their wages 00:09:07.100 --> 00:09:09.559 expense is zero. Their rent expense is zero. 00:09:09.740 --> 00:09:12.399 They think they're crushing it. They do. But 00:09:12.399 --> 00:09:14.500 the moment they factor in the lost opportunity, 00:09:14.759 --> 00:09:17.919 that salary they sacrificed, the economic picture 00:09:17.919 --> 00:09:20.700 can flip completely. It can go from a positive 00:09:20.700 --> 00:09:23.889 profit to a substantial loss. And that's why 00:09:23.889 --> 00:09:27.929 understanding this dual nature of costs is really 00:09:27.929 --> 00:09:30.909 the gateway to understanding efficiency. If you 00:09:30.909 --> 00:09:33.509 don't account for the implicit sacrifice, you 00:09:33.509 --> 00:09:35.350 are just deceiving yourself about the economic 00:09:35.350 --> 00:09:37.950 viability of your actions. You really are. So 00:09:37.950 --> 00:09:41.370 with the distinction between explicit and implicit 00:09:41.370 --> 00:09:44.450 costs now clarified, we need to take a quick 00:09:44.450 --> 00:09:46.110 step back before we get into the applications. 00:09:46.309 --> 00:09:49.029 Okay. Because to use opportunity cost effectively, 00:09:49.250 --> 00:09:51.870 you really have to know what it isn't. That's 00:09:51.870 --> 00:09:54.799 a critical point. So many people muddy the strategic 00:09:54.799 --> 00:09:57.360 water with concepts that serve completely different 00:09:57.360 --> 00:09:59.539 purposes. Right. There are these distinct economic 00:09:59.539 --> 00:10:02.899 concepts, sunk cost, marginal cost, adjustment 00:10:02.899 --> 00:10:05.519 cost, that are often confused with opportunity 00:10:05.519 --> 00:10:08.559 cost, but they relate to different phases of 00:10:08.559 --> 00:10:10.559 decision making. We need to draw a clear line 00:10:10.559 --> 00:10:13.700 between true opportunity cost and these. These 00:10:13.700 --> 00:10:16.399 common misrepresentations. Let's start with some 00:10:16.399 --> 00:10:18.379 costs. They're often called historical costs. 00:10:18.480 --> 00:10:19.879 Right. The definition is very straightforward. 00:10:20.340 --> 00:10:22.659 These are expenses that have already been incurred 00:10:22.659 --> 00:10:25.639 and are unrecoverable. The classic personal finance 00:10:25.639 --> 00:10:28.240 trap. You bought a non -refundable plane ticket 00:10:28.240 --> 00:10:30.740 that you now dread taking. Or an annual gym membership 00:10:30.740 --> 00:10:33.080 you never use. Exactly. That money is already 00:10:33.080 --> 00:10:36.179 gone. It's in the past. It's sunk. And that is 00:10:36.179 --> 00:10:39.549 the crucial implication. Because sunk costs remain 00:10:39.549 --> 00:10:42.049 unchanged, regardless of your future action, 00:10:42.250 --> 00:10:44.970 they should logically have zero influence on 00:10:44.970 --> 00:10:47.529 any present or future decisions. So all your 00:10:47.529 --> 00:10:50.350 decisions should only be based on future expected 00:10:50.350 --> 00:10:53.740 benefits and costs. Only. But humans are terrible 00:10:53.740 --> 00:10:55.940 at this. We commit what's called the sunk cost 00:10:55.940 --> 00:10:59.080 fallacy all the time. Oh, constantly. I force 00:10:59.080 --> 00:11:01.379 myself to finish a boring movie or read a terrible 00:11:01.379 --> 00:11:03.519 book simply because I've already invested three 00:11:03.519 --> 00:11:05.779 hours into it. That's the psychological friction. 00:11:06.120 --> 00:11:08.960 But rationally, those three hours are lost regardless 00:11:08.960 --> 00:11:11.659 of what you do next. The only variable you still 00:11:11.659 --> 00:11:13.659 control is the next three hours of your life. 00:11:13.840 --> 00:11:16.159 So by forcing myself to continue, I'm just compounding 00:11:16.159 --> 00:11:18.600 the error. You are. You're adding an additional 00:11:18.600 --> 00:11:21.259 implicit cost of three hours of wasted time and 00:11:21.259 --> 00:11:23.879 displeasure. The money for the movie ticket is 00:11:23.879 --> 00:11:26.559 lost no matter what, but the opportunity cost 00:11:26.559 --> 00:11:30.000 of finishing that terrible movie is the enjoyment 00:11:30.000 --> 00:11:32.980 you forego from watching the best available alternative. 00:11:33.340 --> 00:11:35.460 Or just turning the screen off and going to bed. 00:11:35.679 --> 00:11:37.679 Which might have the highest utility of all. 00:11:37.899 --> 00:11:41.379 The past is the past. Decisions should be forward 00:11:41.379 --> 00:11:43.480 -looking. That's a great rule of thumb. Okay, 00:11:43.539 --> 00:11:46.440 so that's sunk costs. Next, let's look at marginal 00:11:46.440 --> 00:11:49.269 cost. This is another one that's often confused 00:11:49.269 --> 00:11:51.590 with opportunity cost, but they focus on two 00:11:51.590 --> 00:11:53.809 totally different scales of decision making. 00:11:54.049 --> 00:11:56.610 They do. Opportunity cost is about the choice 00:11:56.610 --> 00:11:58.870 between mutually exclusive alternatives. Do I 00:11:58.870 --> 00:12:01.450 do A or do I do B? Right. Whereas marginal cost 00:12:01.450 --> 00:12:03.370 is about the incremental cost of production. 00:12:03.570 --> 00:12:06.210 How much does one more unit of my product cost 00:12:06.210 --> 00:12:09.950 me to make? Exactly. Marginal cost, or MC, is 00:12:09.950 --> 00:12:12.250 focused purely on the next unit produced for 00:12:12.250 --> 00:12:15.730 an existing product line. Mathematically, it's 00:12:15.730 --> 00:12:18.409 just the change in total cost divided by the 00:12:18.409 --> 00:12:20.750 corresponding change in output. It's the increase 00:12:20.750 --> 00:12:22.730 in your total cost when you increase your output 00:12:22.730 --> 00:12:26.169 by just one unit. Just one. The example of building 00:12:26.169 --> 00:12:28.950 aircraft clarifies this perfectly. Building the 00:12:28.950 --> 00:12:31.769 very first aircraft involves massive setup costs. 00:12:32.110 --> 00:12:36.090 All the R &D, tooling, testing, design. A huge 00:12:36.090 --> 00:12:38.970 initial investment. Huge. But once that production 00:12:38.970 --> 00:12:42.210 line is established, the 100 aircraft benefits 00:12:42.210 --> 00:12:45.269 from economies of scale and what's called the 00:12:45.269 --> 00:12:47.909 organizational learning curve. So the total cost 00:12:47.909 --> 00:12:51.200 is high, but the marginal cost. the cost to produce 00:12:51.200 --> 00:12:54.179 that 100th plane, will be significantly lower 00:12:54.179 --> 00:12:56.480 than the first or second. Much lower. And the 00:12:56.480 --> 00:12:59.360 manufacturer is intensely focused on driving 00:12:59.360 --> 00:13:02.000 down that incremental expense per unit. That's 00:13:02.000 --> 00:13:04.139 how they maximize their profit margin. Opportunity 00:13:04.139 --> 00:13:06.639 cost, in contrast, would ask a totally different 00:13:06.639 --> 00:13:08.840 question. A much bigger question it would ask. 00:13:08.919 --> 00:13:11.240 If we didn't build any airplanes at all, What 00:13:11.240 --> 00:13:13.960 is the best alternative use for this entire factory, 00:13:14.080 --> 00:13:16.179 this capital, and this highly skilled workforce? 00:13:16.580 --> 00:13:18.279 So they're operating on completely different 00:13:18.279 --> 00:13:21.179 planes of strategic thought. MC is about operational 00:13:21.179 --> 00:13:23.740 optimization. OC is about resource allocation 00:13:23.740 --> 00:13:26.620 optimization. Perfect way to put it. Now, our 00:13:26.620 --> 00:13:28.240 third exclusion is something called adjustment 00:13:28.240 --> 00:13:31.830 costs. This refers to the expenses a company 00:13:31.830 --> 00:13:34.450 bears when it has to alter its production levels. 00:13:34.669 --> 00:13:37.370 Usually in response to some big market shift, 00:13:37.509 --> 00:13:40.970 right? Like a sudden spike in demand or a major 00:13:40.970 --> 00:13:43.029 change in the cost of your materials. Exactly. 00:13:43.029 --> 00:13:45.049 So if you run a widget factory and demand for 00:13:45.049 --> 00:13:47.629 widgets suddenly skyrockets, forcing you to run 00:13:47.629 --> 00:13:49.750 a third shift and buy new machinery. All those 00:13:49.750 --> 00:13:52.210 expenses tied to that rapid expansion are my 00:13:52.210 --> 00:13:55.120 adjustment costs. Precisely. They include costs 00:13:55.120 --> 00:13:58.440 related to acquiring, setting up, and mastering 00:13:58.440 --> 00:14:01.059 new capital equipment, and also the costs tied 00:14:01.059 --> 00:14:04.240 to hiring, dismissing, and training employees 00:14:04.240 --> 00:14:06.980 to modify your production volume. They are the 00:14:06.980 --> 00:14:09.039 costs of transitioning from one stable operating 00:14:09.039 --> 00:14:11.879 level to another. But the sources also broaden 00:14:11.879 --> 00:14:14.340 this definition. It's not just about volume changes. 00:14:14.659 --> 00:14:17.299 Correct. Adjustment costs also apply when a company 00:14:17.299 --> 00:14:20.019 shifts the nature of its product itself. If a 00:14:20.019 --> 00:14:22.620 tech company decides to retool its flagship product 00:14:22.620 --> 00:14:25.299 to compete better, To add new features, for example. 00:14:25.480 --> 00:14:27.519 Right, to enhance competition through differentiation. 00:14:28.299 --> 00:14:31.340 That process incurs significant adjustment costs. 00:14:31.480 --> 00:14:34.039 It involves the expense of reassigning capital 00:14:34.039 --> 00:14:36.720 and labor, adapting the organization's expertise, 00:14:37.039 --> 00:14:39.580 and maybe even overhauling the entire supply 00:14:39.580 --> 00:14:42.100 chain. This helps us see the distinction so clearly. 00:14:43.100 --> 00:14:46.519 Sunk costs are the past. Marginal cost is the 00:14:46.519 --> 00:14:49.320 very next unit. Adjustment costs are the price 00:14:49.320 --> 00:14:51.419 of organizational transition. And opportunity 00:14:51.419 --> 00:14:54.120 cost is the true measure of what you sacrifice 00:14:54.120 --> 00:14:56.639 for the entire choice. We have now established 00:14:56.639 --> 00:14:58.840 what opportunity cost is and what it is not. 00:14:59.100 --> 00:15:01.360 So now we get to the core of this deep dive. 00:15:01.580 --> 00:15:05.659 Segment three, the practical uses. Why does this 00:15:05.659 --> 00:15:07.840 theoretical concept drive the highest stakes 00:15:07.840 --> 00:15:10.500 decisions in business, trade, and even government? 00:15:10.940 --> 00:15:12.720 This is where we really move from the classroom 00:15:12.720 --> 00:15:14.519 to the boardroom because the calculation of opportunity 00:15:14.519 --> 00:15:16.559 costs is, I mean, it's the difference between 00:15:16.559 --> 00:15:18.759 surviving and thriving. Let's start with the 00:15:18.759 --> 00:15:20.639 business world. This is where the divergence 00:15:20.639 --> 00:15:23.340 between basic bookkeeping and real strategic 00:15:23.340 --> 00:15:25.799 decision -making becomes. Well, it's unavoidable. 00:15:26.039 --> 00:15:27.820 Here's where it gets really interesting. We're 00:15:27.820 --> 00:15:30.120 talking about the difference between economic 00:15:30.120 --> 00:15:33.220 profit and accounting profit. Okay, so accounting 00:15:33.220 --> 00:15:35.980 profit is simple. Its only objective is fiscal 00:15:35.980 --> 00:15:38.919 reporting. It's for stakeholders, for tax purposes, 00:15:39.220 --> 00:15:41.960 usually done quarterly or annually. And it focuses 00:15:41.960 --> 00:15:45.659 only on those tangible, measurable cash flows. 00:15:45.940 --> 00:15:49.519 Total revenue minus explicit costs. That's it. 00:15:49.820 --> 00:15:52.620 Crucially, opportunity costs are excluded. Why? 00:15:52.879 --> 00:15:55.440 Yeah. Because they don't involve a monetary transaction 00:15:55.440 --> 00:15:57.759 that you can put on a report. And if you rely 00:15:57.759 --> 00:16:00.059 solely on that number, on that accounting profit, 00:16:00.360 --> 00:16:02.100 you can fool yourself into thinking you've made 00:16:02.100 --> 00:16:04.500 a brilliant strategic decision. When, in fact, 00:16:04.620 --> 00:16:07.590 you've chosen a path. That severely underutilizes 00:16:07.590 --> 00:16:09.769 your resources. Right. Which is why the entire 00:16:09.769 --> 00:16:12.090 purpose of calculating economic profit is to 00:16:12.090 --> 00:16:14.629 aid in better business decision making. And it 00:16:14.629 --> 00:16:16.570 does that through the vital inclusion of all 00:16:16.570 --> 00:16:19.669 opportunity costs, both the explicit cash outflows 00:16:19.669 --> 00:16:22.690 and the implicit value you've foregone. So this 00:16:22.690 --> 00:16:24.769 allows a business to conduct a true evaluation 00:16:24.769 --> 00:16:27.669 asking, is this allocation of our resources truly 00:16:27.669 --> 00:16:30.549 cost effective? Or should we be reallocating 00:16:30.549 --> 00:16:32.669 our capital and our time to the next best alternative? 00:16:33.309 --> 00:16:35.009 Let's go back to that simplified example from 00:16:35.009 --> 00:16:36.509 the source material, but let's really look at 00:16:36.509 --> 00:16:39.789 the numbers. Imagine a new startup. In its first 00:16:39.789 --> 00:16:43.309 year, it generates $10 ,000 in accounting profit. 00:16:43.529 --> 00:16:45.750 The owner is ecstatic. They made $10 ,000. They 00:16:45.750 --> 00:16:48.570 think they're winning. Yeah. But we have to factor 00:16:48.570 --> 00:16:51.149 in the implicit costs. Let's say the owner is 00:16:51.149 --> 00:16:54.350 a former executive who gave up a $75 ,000 salary 00:16:54.350 --> 00:16:56.570 to launch this startup. Okay, that's a big one. 00:16:57.049 --> 00:16:59.889 A very big one. And let's also say they liquidated 00:16:59.889 --> 00:17:02.950 a stock portfolio that was worth $100 ,000, which 00:17:02.950 --> 00:17:06.130 was generating a reliable 5 % return or $5 ,000 00:17:06.130 --> 00:17:08.730 a year to fund the business. So the implicit 00:17:08.730 --> 00:17:10.890 opportunity costs are adding up fast. You have 00:17:10.890 --> 00:17:13.900 the $75 ,000 in foregone salary. Plus the $5 00:17:13.900 --> 00:17:16.359 ,000 in foregone investment return. That's a 00:17:16.359 --> 00:17:19.240 total of $80 ,000 in implicit costs. So when 00:17:19.240 --> 00:17:21.259 we calculate the economic profit, we take the 00:17:21.259 --> 00:17:23.559 accounting profit, the $10 ,000, and we subtract 00:17:23.559 --> 00:17:26.619 the total opportunity costs. The $80 ,000. The 00:17:26.619 --> 00:17:29.420 result is a substantial negative $70 ,000 in 00:17:29.420 --> 00:17:31.700 economic profit. And that negative number is 00:17:31.700 --> 00:17:33.619 the single most critical piece of information 00:17:33.619 --> 00:17:36.140 for that business owner. It tells them that their 00:17:36.140 --> 00:17:38.160 decision to start the business was imprudent. 00:17:38.480 --> 00:17:40.740 Not because the business failed to generate revenue. 00:17:40.940 --> 00:17:43.640 No, it made money. Yeah. But because the opportunity 00:17:43.640 --> 00:17:47.460 costs, the benefits they sacrificed to make that 00:17:47.460 --> 00:17:50.720 money far outweigh the profit they earned. That 00:17:50.720 --> 00:17:54.539 owner is economically worse off by $70 ,000 compared 00:17:54.539 --> 00:17:57.250 to their next best alternative. Which was just 00:17:57.250 --> 00:17:59.390 staying in their executive job and keeping their 00:17:59.390 --> 00:18:01.950 investment portfolio. Right. That negative economic 00:18:01.950 --> 00:18:05.130 profit provides a powerful, rational incentive 00:18:05.130 --> 00:18:07.809 for that owner to reallocate their resources, 00:18:07.930 --> 00:18:10.329 to maybe shut down the business and go back to 00:18:10.329 --> 00:18:13.609 that $75 ,000 salary job. What happens if the 00:18:13.609 --> 00:18:16.849 calculation comes out to exactly zero? Ah, that's 00:18:16.849 --> 00:18:19.170 what economists call a normal profit. This is 00:18:19.170 --> 00:18:21.730 the equilibrium condition. It means the business 00:18:21.730 --> 00:18:24.170 is covering all its explicit costs and all its 00:18:24.170 --> 00:18:27.210 implicit costs. All opportunity costs are covered 00:18:27.210 --> 00:18:29.410 by the total revenue. So it means the resources 00:18:29.410 --> 00:18:32.029 you're using are generating exactly as much value 00:18:32.029 --> 00:18:34.069 in this business as they would in their next 00:18:34.069 --> 00:18:36.490 best alternative. Precisely. So if you're making 00:18:36.490 --> 00:18:38.410 a normal profit, you're perfectly efficient. 00:18:38.609 --> 00:18:41.390 You have no incentive to leave because you can't 00:18:41.390 --> 00:18:43.170 do any better elsewhere. You're optimizing efficiency. 00:18:43.730 --> 00:18:46.890 You are. And the pursuit of a positive economic 00:18:46.890 --> 00:18:49.609 profit is what drives entrepreneurs and markets. 00:18:50.109 --> 00:18:52.849 It's the desire to earn more than the cost of 00:18:52.849 --> 00:18:55.309 all your alternatives combined. Beyond this really 00:18:55.309 --> 00:18:57.829 foundational distinction, modern finance has 00:18:57.829 --> 00:19:00.309 started to incorporate opportunity cost into 00:19:00.309 --> 00:19:02.529 some very high level performance measures. Oh, 00:19:02.549 --> 00:19:04.849 absolutely. Especially those focused on risk 00:19:04.849 --> 00:19:07.549 management. Yeah. We have metrics like risk -adjusted 00:19:07.549 --> 00:19:10.789 return on capital or RIROC and economic value 00:19:10.789 --> 00:19:13.869 added or EVA. And what do those do? These advanced 00:19:13.869 --> 00:19:16.309 tools try to explicitly quantify opportunity 00:19:16.309 --> 00:19:19.630 costs to help businesses manage risk and optimize 00:19:19.630 --> 00:19:21.950 how they allocate their capital. They don't just 00:19:21.950 --> 00:19:24.500 ask. Did we make money? They ask a much harder 00:19:24.500 --> 00:19:26.839 question. Which is? Did this use of our resources 00:19:26.839 --> 00:19:29.900 generate a return that sufficiently compensated 00:19:29.900 --> 00:19:32.140 us for the risk we took and for all the alternatives 00:19:32.140 --> 00:19:34.440 we had to forego? And this leads us straight 00:19:34.440 --> 00:19:36.380 to the critical connection with what's really 00:19:36.380 --> 00:19:38.539 the gold standard of investment decision making, 00:19:38.740 --> 00:19:42.240 the discounted cash flow method or DCF. The DCF 00:19:42.240 --> 00:19:44.839 method is the primary tool for valuing investments. 00:19:45.099 --> 00:19:47.640 An opportunity cost is an absolutely essential 00:19:47.640 --> 00:19:50.460 metric of cash outflow in this estimation. It's 00:19:50.460 --> 00:19:53.039 baked right in. How does it influence the DCF 00:19:53.039 --> 00:19:55.359 calculation? I mean, that seems inherently mathematical. 00:19:55.920 --> 00:19:58.279 It does so primarily through the discount rate. 00:19:58.589 --> 00:20:01.190 The discount rate you apply in a DCF analysis 00:20:01.190 --> 00:20:03.789 represents the rate of return required by your 00:20:03.789 --> 00:20:06.269 investors. And this rate is heavily influenced 00:20:06.269 --> 00:20:08.349 by the firm's cost of capital. Often called the 00:20:08.349 --> 00:20:11.609 weighted average cost of capital or WACC. And 00:20:11.609 --> 00:20:15.490 WACC is fundamentally an opportunity cost. It 00:20:15.490 --> 00:20:17.190 measures what your investors could be earning 00:20:17.190 --> 00:20:20.069 on other investments of similar risk. Ah, so 00:20:20.069 --> 00:20:23.549 if my company's WACC is 10%, that means my projects 00:20:23.549 --> 00:20:26.269 have to return more than 10%. Because 10 % is 00:20:26.269 --> 00:20:28.930 the opportunity cost, it's... the return my investors 00:20:28.930 --> 00:20:31.049 are giving up by putting their money with me 00:20:31.049 --> 00:20:34.069 instead of in the next best equivalent risk investment. 00:20:34.309 --> 00:20:37.289 That is it. Exactly. If your project A is expected 00:20:37.289 --> 00:20:40.230 to return 8%, but the opportunity cost of your 00:20:40.230 --> 00:20:44.630 capital, your WACC, is 10%, then project A, even 00:20:44.630 --> 00:20:46.890 though it's profitable on paper, should be rejected. 00:20:47.450 --> 00:20:50.109 It provides a negative economic profit compared 00:20:50.109 --> 00:20:52.150 to the alternatives available to your investors. 00:20:52.470 --> 00:20:54.089 And there was a second point you mentioned earlier, 00:20:54.150 --> 00:20:56.390 which I think is often missed in basic finance 00:20:56.390 --> 00:21:00.009 courses. It deals with assets the company already 00:21:00.009 --> 00:21:02.769 owns. This is a massive point of self -deception 00:21:02.769 --> 00:21:05.769 in business planning. It really is. Say a company 00:21:05.769 --> 00:21:07.670 is launching a new project that requires a piece 00:21:07.670 --> 00:21:10.910 of land they already own or maybe a proprietary 00:21:10.910 --> 00:21:13.029 piece of machinery that's been fully paid for. 00:21:13.190 --> 00:21:15.829 So there's no cash outflow needed to buy these 00:21:15.829 --> 00:21:18.549 assets. The natural inclination is to assume 00:21:18.549 --> 00:21:21.869 their cost for this project is zero. Right. But 00:21:21.869 --> 00:21:24.329 the sources are very clear on this. The cost 00:21:24.329 --> 00:21:26.599 of that asset. must still be included in the 00:21:26.599 --> 00:21:28.680 cash outflow calculation at its current market 00:21:28.680 --> 00:21:30.839 price. Because that money could have been generated 00:21:30.839 --> 00:21:33.640 by selling or leasing that asset to a third party 00:21:33.640 --> 00:21:36.799 on the open market. That potential income, whether 00:21:36.799 --> 00:21:38.700 it's from a lease payment or an outright sale, 00:21:38.960 --> 00:21:41.900 represents the opportunity cost of using that 00:21:41.900 --> 00:21:44.519 asset internally in your own business venture. 00:21:45.099 --> 00:21:48.140 So if you fail to incorporate that foregone income 00:21:48.140 --> 00:21:51.440 into your DCF cash outflow estimate, you will 00:21:51.440 --> 00:21:53.759 artificially inflate the project's net present 00:21:53.759 --> 00:21:56.359 value. You'll end up making an adjustment decision 00:21:56.359 --> 00:21:59.779 that is economically erroneous, all because... 00:22:00.000 --> 00:22:02.500 You ignored the opportunity cost of an asset 00:22:02.500 --> 00:22:04.819 you already owned. It forces you to value your 00:22:04.819 --> 00:22:07.559 resources, even those you possess, based on their 00:22:07.559 --> 00:22:09.920 highest market value elsewhere. It's a key defense 00:22:09.920 --> 00:22:12.680 mechanism against business bias. It truly is. 00:22:12.839 --> 00:22:14.480 Okay, so now let's shift our focus. We're going 00:22:14.480 --> 00:22:17.460 from micro -level business strategy to macro 00:22:17.460 --> 00:22:20.140 -level global strategy, international trade. 00:22:20.650 --> 00:22:23.390 And what's so fascinating here is that opportunity 00:22:23.390 --> 00:22:25.809 cost isn't just a part of modern trade theory. 00:22:25.890 --> 00:22:28.250 It is the absolute foundation of it. And this 00:22:28.250 --> 00:22:29.890 theory revolves around the distinction between 00:22:29.890 --> 00:22:33.089 two key concepts, comparative advantage and absolute 00:22:33.089 --> 00:22:35.309 advantage. Let's start with absolute advantage. 00:22:35.690 --> 00:22:39.119 It's about straightforward efficiency. If country 00:22:39.119 --> 00:22:42.180 A can produce a laptop using 100 man hours and 00:22:42.180 --> 00:22:46.019 country B requires 150 man hours to produce the 00:22:46.019 --> 00:22:48.440 exact same laptop. Country A has the absolute 00:22:48.440 --> 00:22:50.799 advantage. They just use fewer resources to do 00:22:50.799 --> 00:22:53.200 it. They're just better at it. Right. But absolute 00:22:53.200 --> 00:22:55.559 advantage doesn't actually tell us where the 00:22:55.559 --> 00:22:58.119 economic gain from trade comes from. That's where 00:22:58.119 --> 00:23:00.720 comparative advantage steps in and is defined 00:23:00.720 --> 00:23:03.720 purely by opportunity cost. So what's the definition? 00:23:04.359 --> 00:23:06.400 Comparative advantage is defined by a nation 00:23:06.400 --> 00:23:09.259 producing a product. at a relatively lower opportunity 00:23:09.259 --> 00:23:12.220 cost compared to its competitors. So they give 00:23:12.220 --> 00:23:14.400 up less of their alternative resource to make 00:23:14.400 --> 00:23:16.420 that product. They give up less. This is the 00:23:16.420 --> 00:23:19.059 great insight from David Ricardo. A country doesn't 00:23:19.059 --> 00:23:21.000 have to be the best at something to benefit from 00:23:21.000 --> 00:23:23.359 specializing in it. It just has to be the one 00:23:23.359 --> 00:23:26.140 that, for lack of a better term, sucks the least 00:23:26.140 --> 00:23:28.599 at it. in terms of the sacrifice required. Okay, 00:23:28.660 --> 00:23:30.839 let's use the classic tea and wool example from 00:23:30.839 --> 00:23:33.019 the sources and really make the math clear. This 00:23:33.019 --> 00:23:34.819 is the key insight we want you to take away. 00:23:35.000 --> 00:23:37.559 Sounds good. So suppose we have two countries, 00:23:37.700 --> 00:23:40.400 country A and country B. They can only produce 00:23:40.400 --> 00:23:43.339 two things, tea and wool. Yeah. And let's say 00:23:43.339 --> 00:23:46.099 each country has 100 total units of labor. Okay. 00:23:46.200 --> 00:23:49.099 In country A... One unit of labor can produce 00:23:49.099 --> 00:23:52.380 either five tons of tea or R, one ton of wool. 00:23:52.660 --> 00:23:55.500 So to make one ton of wool, country A must sacrifice 00:23:55.500 --> 00:23:58.720 making five tons of tea. So the opportunity cost 00:23:58.720 --> 00:24:01.599 of one ton of wool is five tons of tea? Correct. 00:24:01.640 --> 00:24:03.299 And to make one ton of tea, they have to give 00:24:03.299 --> 00:24:06.259 up one -fifth or 0 .2 tons of wool. That's the 00:24:06.259 --> 00:24:08.750 opportunity cost of tea for country A. Got it. 00:24:08.829 --> 00:24:11.650 Now, for country B, our sources say country B 00:24:11.650 --> 00:24:14.210 is generally less efficient. One unit of their 00:24:14.210 --> 00:24:17.509 labor can produce only 0 .3 tons of tea or one 00:24:17.509 --> 00:24:19.690 ton of wool. So for country B to make one ton 00:24:19.690 --> 00:24:22.269 of wool, they only have to sacrifice 0 .3 tons 00:24:22.269 --> 00:24:23.910 of tea. And to make one ton of tea, they have 00:24:23.910 --> 00:24:26.210 to sacrifice one divided by 0 .3, which is about 00:24:26.210 --> 00:24:29.029 3 .3 tons of wool. Right. The comparison here 00:24:29.029 --> 00:24:31.069 is startling, even though country A is far better 00:24:31.069 --> 00:24:32.930 at producing everything. They have the absolute 00:24:32.930 --> 00:24:35.559 advantage in both goods, right? Not quite. They 00:24:35.559 --> 00:24:37.259 have the absolute advantage in tea, for sure, 00:24:37.339 --> 00:24:40.619 5 tons versus 0 .3. But in wool, both countries 00:24:40.619 --> 00:24:43.299 can produce 1 ton with 1 unit of labor, so there's 00:24:43.299 --> 00:24:45.759 no absolute advantage there. But they still benefit 00:24:45.759 --> 00:24:48.039 immensely from trade. Okay, so let's look at 00:24:48.039 --> 00:24:50.279 the opportunity costs again. For tea production, 00:24:50.619 --> 00:24:54.720 country A's OC is only 0 .2 tons of wool. Country 00:24:54.720 --> 00:24:59.359 B's OC is a whopping 3 .3 tons of wool. So conclusion 00:24:59.359 --> 00:25:01.779 number one is clear. Country A has the comparative 00:25:01.779 --> 00:25:04.500 advantage in tea production because of that vastly 00:25:04.500 --> 00:25:07.559 lower opportunity cost. They give up a tiny fraction 00:25:07.559 --> 00:25:09.519 of wool to make tea. Now let's look at wool. 00:25:09.660 --> 00:25:12.819 For wool production, Country A's OC is 5 tons 00:25:12.819 --> 00:25:16.359 of tea. Country B's OC is just 0 .3 tons of tea. 00:25:16.640 --> 00:25:19.240 Conclusion number two. Country B has the comparative 00:25:19.240 --> 00:25:21.200 advantage in wool production. They sacrifice 00:25:21.200 --> 00:25:23.339 far less tea to produce a ton of wool than Country 00:25:23.339 --> 00:25:26.079 A does. This is the genius of the theory. Country 00:25:26.079 --> 00:25:28.279 B should specialize in wool. Even though they 00:25:28.279 --> 00:25:30.859 aren't necessarily a more efficient overall producer. 00:25:31.160 --> 00:25:34.140 Exactly. The implication for global policy is 00:25:34.140 --> 00:25:37.519 just profound. By specializing purely in what 00:25:37.519 --> 00:25:39.680 they have a comparative advantage in, and then 00:25:39.680 --> 00:25:42.160 trading for the other product, both countries 00:25:42.160 --> 00:25:44.240 can consume more of both goods than they ever 00:25:44.240 --> 00:25:46.240 could have if they tried to produce everything 00:25:46.240 --> 00:25:49.000 in isolation. It ensures the most efficient use 00:25:49.000 --> 00:25:52.049 of resources on a global scale. all driven by 00:25:52.049 --> 00:25:54.269 that simple ratio calculation of opportunity 00:25:54.269 --> 00:25:57.890 cost. It shifts the entire focus from who is 00:25:57.890 --> 00:26:00.970 better to who loses less. And that same principle 00:26:00.970 --> 00:26:03.490 of maximizing resource efficiency scales all 00:26:03.490 --> 00:26:05.990 the way up to governmental policy and resource 00:26:05.990 --> 00:26:08.650 allocation. Governments constantly face these 00:26:08.650 --> 00:26:10.930 incredibly high stakes tradeoffs where opportunity 00:26:10.930 --> 00:26:13.950 cost has to be quantified. It has to be. Let's 00:26:13.950 --> 00:26:16.029 use the example of government spending on a major 00:26:16.029 --> 00:26:18.769 conflict. Say entering a war costs the government 00:26:18.769 --> 00:26:22.470 $840 billion in direct explicit cost wages for 00:26:22.470 --> 00:26:24.829 personnel, buying equipment, all the material. 00:26:25.089 --> 00:26:28.349 The public naturally focuses on that $840 million 00:26:28.349 --> 00:26:31.490 explicit cost. It's a huge number. And rightfully 00:26:31.490 --> 00:26:34.420 so. But the true price of that war is the opportunity 00:26:34.420 --> 00:26:37.579 cost. It's the $840 billion that is now prevented 00:26:37.579 --> 00:26:40.019 from funding any domestic priorities. That money 00:26:40.019 --> 00:26:41.839 could have been used to fund health care initiatives 00:26:41.839 --> 00:26:44.779 or to slash budget deficits. Or provide substantial 00:26:44.779 --> 00:26:47.880 tax cuts to stimulate the economy. The decision 00:26:47.880 --> 00:26:50.519 to pursue the war is implicitly a decision to 00:26:50.519 --> 00:26:53.279 forego those specific benefits. The economic 00:26:53.279 --> 00:26:56.099 cost is the loss of the best foregone alternative, 00:26:56.440 --> 00:26:58.599 whether that was a new highway system or better 00:26:58.599 --> 00:27:01.319 schools. And just like in business, the implicit 00:27:01.319 --> 00:27:04.400 costs here cascade long after the conflict is 00:27:04.400 --> 00:27:07.210 over. They absolutely do. The implicit costs 00:27:07.210 --> 00:27:11.089 include the lost output as resources labor, capital 00:27:11.089 --> 00:27:13.509 are shifted from civilian high productivity sectors 00:27:13.509 --> 00:27:16.630 to military production. And more complexly, you 00:27:16.630 --> 00:27:19.529 have the long -term deferred implicit costs. 00:27:20.150 --> 00:27:22.789 Decades of mandated veteran health care, future 00:27:22.789 --> 00:27:24.430 interest payments on the debt incurred to pay 00:27:24.430 --> 00:27:26.589 for the war, damage to international diplomatic 00:27:26.589 --> 00:27:29.630 relations. All of these represent foregone future 00:27:29.630 --> 00:27:32.539 policy options and lost utility. For a recent 00:27:32.539 --> 00:27:34.940 and incredibly comprehensive illustration of 00:27:34.940 --> 00:27:37.359 opportunity costs at the national level, we have 00:27:37.359 --> 00:27:39.599 to look at the governmental response to the COVID 00:27:39.599 --> 00:27:42.680 -19 pandemic. Oh, absolutely. That scenario offers 00:27:42.680 --> 00:27:45.359 a powerful case study in simultaneous large -scale 00:27:45.359 --> 00:27:48.289 explicit and implicit costs. The scale of the 00:27:48.289 --> 00:27:51.069 economic response was just unprecedented. We 00:27:51.069 --> 00:27:54.289 saw massive explicit costs. Our sources detail 00:27:54.289 --> 00:27:57.769 the direct expenses, $4 .5 billion on medical 00:27:57.769 --> 00:28:01.549 bills, over $17 billion on vaccine distribution. 00:28:01.990 --> 00:28:04.869 And hundreds of billions more poured into economic 00:28:04.869 --> 00:28:08.230 stimulus plans. These costs resulted in soaring 00:28:08.230 --> 00:28:11.069 public debt and at the same time decreased tax 00:28:11.069 --> 00:28:13.670 income as economies slowed down. But the true 00:28:13.670 --> 00:28:16.650 toll of the crisis, both economically and socially, 00:28:16.880 --> 00:28:19.880 really lay in the implicit opportunity costs, 00:28:20.059 --> 00:28:22.299 the benefits that were necessarily sacrificed 00:28:22.299 --> 00:28:25.279 to achieve the primary objective of public health 00:28:25.279 --> 00:28:27.519 containment. And that includes things like the 00:28:27.519 --> 00:28:30.799 $158 billion loss that's directly attributed 00:28:30.799 --> 00:28:32.920 to decreased economic activity from restrictions 00:28:32.920 --> 00:28:35.079 and lockdowns. But it goes so much deeper than 00:28:35.079 --> 00:28:36.799 that. You mean the reallocation of attention 00:28:36.799 --> 00:28:39.299 and resources away from routine services and 00:28:39.299 --> 00:28:41.619 toward the emergency COVID response. Exactly. 00:28:41.700 --> 00:28:43.940 That meant a massive implicit cost in public 00:28:43.940 --> 00:28:45.900 welfare. We're talking about delayed cancer screening. 00:28:46.089 --> 00:28:48.150 postponed non -emergency surgeries. The long 00:28:48.150 --> 00:28:50.369 -term educational loss due to remote learning, 00:28:50.450 --> 00:28:52.250 which we now know disproportionately affected 00:28:52.250 --> 00:28:54.609 certain demographics. These are all benefits 00:28:54.609 --> 00:28:57.470 or utility that were consciously foregone as 00:28:57.470 --> 00:29:00.009 a society. So things like the rise in mental 00:29:00.009 --> 00:29:02.769 health issues, the loss of social cohesion, the 00:29:02.769 --> 00:29:06.099 slowed economic growth. These are harder to put 00:29:06.099 --> 00:29:08.779 a precise dollar value on. Much harder. But they 00:29:08.779 --> 00:29:11.359 represent a substantial opportunity cost because 00:29:11.359 --> 00:29:14.440 the resources, the time, the facilities, the 00:29:14.440 --> 00:29:16.539 capital that could have been used to maintain 00:29:16.539 --> 00:29:19.180 or improve those conditions were locked down 00:29:19.180 --> 00:29:22.140 or redirected. The implicit cost of saving lives 00:29:22.140 --> 00:29:25.079 through lockdown was, for many, the quality of 00:29:25.079 --> 00:29:27.000 their life and the integrity of their community. 00:29:27.279 --> 00:29:29.180 And this brings us to a specific field where 00:29:29.180 --> 00:29:32.119 opportunity cost is not just a tool, but an ethical 00:29:32.119 --> 00:29:34.519 and structural necessity. Yeah. Health equity. 00:29:36.500 --> 00:29:39.380 In any health system, and certainly during the 00:29:39.380 --> 00:29:42.079 pandemic, opportunity cost is central to efficiency 00:29:42.079 --> 00:29:45.660 decisions. Resources are finite, and every decision 00:29:45.660 --> 00:29:47.700 to treat patient A means consciously accepting 00:29:47.700 --> 00:29:50.000 that you may not be able to treat patient B. 00:29:50.200 --> 00:29:52.920 During the peak of the COVID -19 crisis, the 00:29:52.920 --> 00:29:55.740 scarce resources were incredibly stark. We were 00:29:55.740 --> 00:29:58.180 talking about intensive care unit ICU bed days. 00:29:58.880 --> 00:30:01.700 ventilation time, therapeutic equipment, and 00:30:01.700 --> 00:30:03.759 of course, specialized medical staff. It was 00:30:03.759 --> 00:30:05.880 a textbook example of supply and demand disruption. 00:30:06.319 --> 00:30:09.359 It was. The demand curve for hospital beds shifted 00:30:09.359 --> 00:30:11.559 sharply to the right because severely infected 00:30:11.559 --> 00:30:14.279 patients required much longer hospital stays. 00:30:14.779 --> 00:30:17.980 At the same time, supply often shifted left due 00:30:17.980 --> 00:30:21.299 to staff shortages, burnout, or the need to decommission 00:30:21.299 --> 00:30:24.039 beds for contamination control. So the system 00:30:24.039 --> 00:30:26.460 was shrinking while the need was exploding. This 00:30:26.460 --> 00:30:30.089 is the moment where marginal opportunity Well, 00:30:31.690 --> 00:30:34.049 the balance in a perfect competition model is 00:30:34.049 --> 00:30:36.589 theoretically what we call Pareto optimal, meaning 00:30:36.589 --> 00:30:38.849 no one can be made better off without making 00:30:38.849 --> 00:30:41.190 someone else worse off. When resource scarcity 00:30:41.190 --> 00:30:43.089 hits like that, the system moves away from that 00:30:43.089 --> 00:30:45.430 optimum and medical allocation decisions must 00:30:45.430 --> 00:30:48.710 be made. Triage must happen. So when the system 00:30:48.710 --> 00:30:50.650 runs out of beds or ventilators, the cost of 00:30:50.650 --> 00:30:52.690 treating patient A, the explicit costs of their 00:30:52.690 --> 00:30:55.230 care, is suddenly multiplied by this massive 00:30:55.230 --> 00:30:58.069 implicit opportunity cost. The foregone ability 00:30:58.069 --> 00:31:01.250 to treat patient B, patient C, and patient D. 00:31:01.630 --> 00:31:04.289 who are now turned away or have their own routine, 00:31:04.470 --> 00:31:07.529 life -saving procedures postponed indefinitely. 00:31:07.789 --> 00:31:10.630 Opportunity cost in this context really measures 00:31:10.630 --> 00:31:12.990 the true price of that triage decision. It does. 00:31:13.130 --> 00:31:15.750 And it forces policymakers and health economists 00:31:15.750 --> 00:31:18.950 to quantify the utility lost by the entire population 00:31:18.950 --> 00:31:22.190 when resources are focused entirely on one crisis. 00:31:22.410 --> 00:31:24.990 And hopefully that ensures that future resource 00:31:24.990 --> 00:31:27.609 allocation strategies are based on the highest 00:31:27.609 --> 00:31:29.789 utility for the greatest number of people. This 00:31:29.789 --> 00:31:32.200 has truly been a deep... dive, we've moved from 00:31:32.200 --> 00:31:34.619 the most basic concepts of accounting to the 00:31:34.619 --> 00:31:37.619 highest stakes decisions in medicine and geopolitics. 00:31:37.660 --> 00:31:39.660 I think to synthesize the core message for you, 00:31:39.680 --> 00:31:42.359 it's this. Opportunity cost forces us to engage 00:31:42.359 --> 00:31:44.680 in critical thinking. It forces us to quantify 00:31:44.680 --> 00:31:47.240 not just what we paid in explicit dollars, but 00:31:47.240 --> 00:31:49.640 what we gave up in implicit value. It shifts 00:31:49.640 --> 00:31:52.079 the entire focus from simple reactive accounting 00:31:52.079 --> 00:31:54.759 to proactive, comprehensive economic profitability 00:31:54.759 --> 00:31:57.160 and resource efficiency. And that's true across 00:31:57.160 --> 00:31:59.849 all domains of life. We reviewed three major 00:31:59.849 --> 00:32:02.410 areas where this concept is just indispensable. 00:32:02.789 --> 00:32:05.730 First, in developing better, more honest business 00:32:05.730 --> 00:32:08.750 strategy by calculating true economic profit. 00:32:08.890 --> 00:32:11.490 And its critical role in the DCF valuation model. 00:32:11.710 --> 00:32:14.549 Second, enabling smarter global trade policies 00:32:14.549 --> 00:32:17.170 by specializing in comparative advantage, which 00:32:17.170 --> 00:32:19.819 leads to greater global consumption. And third, 00:32:20.119 --> 00:32:22.740 making those high stakes governmental policy 00:32:22.740 --> 00:32:25.700 choices clearer by forcing an acknowledgement 00:32:25.700 --> 00:32:29.440 of the vast long term implicit costs of something 00:32:29.440 --> 00:32:32.660 like a war or a pandemic response. So what does 00:32:32.660 --> 00:32:35.000 this all mean for you, the listener, right now? 00:32:35.180 --> 00:32:37.599 It means that every decision you make is an optimization 00:32:37.599 --> 00:32:40.880 problem. If time spent researching and managing 00:32:40.880 --> 00:32:43.579 information is an implicit cost, then you are 00:32:43.579 --> 00:32:45.539 constantly giving up a potential return on that 00:32:45.539 --> 00:32:48.289 time invested. Whether that's earning money or 00:32:48.289 --> 00:32:50.910 spending time with family or just engaging in 00:32:50.910 --> 00:32:53.789 leisure. That lost utility is the cost of not 00:32:53.789 --> 00:32:56.210 being well informed. The challenge of opportunity 00:32:56.210 --> 00:32:59.410 cost is that it is always there, whether we choose 00:32:59.410 --> 00:33:01.450 to ignore it or not. I think it's always there. 00:33:01.650 --> 00:33:03.869 The final provocative thought I want to leave 00:33:03.869 --> 00:33:06.990 with you is this. If the average human being 00:33:06.990 --> 00:33:10.450 makes... Dozens of significant high -impact decisions 00:33:10.450 --> 00:33:13.769 every single day. Career choices, personal time 00:33:13.769 --> 00:33:16.589 allocation, investment risks. And we've just 00:33:16.589 --> 00:33:18.430 seen that negative economic profit is driven 00:33:18.430 --> 00:33:21.150 by high opportunity costs. How many of your daily 00:33:21.150 --> 00:33:23.329 decisions result in a negative economic return? 00:33:23.710 --> 00:33:26.150 I challenge you to consider the true price of 00:33:26.150 --> 00:33:28.269 your attention, your time, and your limited capital 00:33:28.269 --> 00:33:30.769 purely through the lens of maximizing foregone 00:33:30.769 --> 00:33:33.630 utility. Are you spending time on the best possible 00:33:33.630 --> 00:33:36.250 use of that limited resource, or are you paying 00:33:36.250 --> 00:33:38.890 too high an opportunity cost? That is the true 00:33:38.890 --> 00:33:39.609 measure of efficiency.
