00:00:43.146 --> 00:00:46.463 After all, economics is all about studying decisions. 00:00:46.563 --> 00:00:49.666 Making a good decision is about comparing the benefits 00:00:49.666 --> 00:00:51.965 of that decision to the costs. 00:00:52.415 --> 00:00:54.033 The obvious costs for this date, 00:00:54.033 --> 00:00:57.697 for Jenny, were the Uber ride she paid for to get here, 00:00:57.793 --> 00:01:01.177 and her grande chai tea latte with whole milk. 00:01:01.483 --> 00:01:03.094 But what's missing? 00:01:03.094 --> 00:01:04.643 Her opportunity cost. 00:01:05.047 --> 00:01:09.329 Opportunity cost means the value of the next best alternative. 00:01:09.472 --> 00:01:12.956 For instance, instead of going on her third date with Adam, 00:01:13.207 --> 00:01:16.475 Jenny could've been binge watching her favorite tv show. 00:01:16.955 --> 00:01:19.423 She might've been on a first date instead, 00:01:19.423 --> 00:01:20.556 with Roman. 00:01:20.674 --> 00:01:22.739 Or she might've been having breakfast 00:01:22.739 --> 00:01:24.423 with her very sweet sister. 00:01:26.073 --> 00:01:27.616 Let's say her next best option 00:01:27.616 --> 00:01:29.690 would've been breakfast with her sister. 00:01:30.325 --> 00:01:32.667 Does the benefit of this third date with Adam 00:01:32.667 --> 00:01:34.733 outweigh the opportunity cost? 00:01:35.265 --> 00:01:38.298 It might seem strange to think this way about romance, 00:01:38.298 --> 00:01:41.999 and it doesn't mean that it's about calculating every decision 00:01:41.999 --> 00:01:43.561 down to the last penny. 00:01:43.743 --> 00:01:46.942 Nonetheless, Jenny's time, attention and energy -- 00:01:46.942 --> 00:01:48.276 those are scarce. 00:01:51.076 --> 00:01:53.850 And if she doesn't consider the alternatives at all, 00:01:53.850 --> 00:01:55.933 she might be wasting parts of her life. 00:01:58.682 --> 00:02:01.562 There's another fundamental related concept 00:02:01.562 --> 00:02:03.751 from economics -- tradeoffs. 00:02:04.585 --> 00:02:06.939 Take these sprinklers in the ceiling of the coffee shop, 00:02:06.939 --> 00:02:08.004 for example. 00:02:09.273 --> 00:02:11.982 Adding sprinklers can make it safer during a fire, 00:02:12.069 --> 00:02:15.018 but they also can cost a lot of money to install. 00:02:16.685 --> 00:02:19.986 How much cheaper would the coffee be without them? 00:02:21.290 --> 00:02:24.456 In a world of scarce resources, one typically has to choose. 00:02:25.066 --> 00:02:28.135 There's a tradeoff -- safer buildings cost more, 00:02:28.135 --> 00:02:30.910 but that means the coffee can be more expensive. 00:02:37.886 --> 00:02:40.796 The line is out the door here. 00:02:41.584 --> 00:02:45.950 Perhaps the owner has considered opening a second location. 00:02:47.329 --> 00:02:50.126 As the building code, however, becomes more stringent, 00:02:50.126 --> 00:02:53.419 the cost of opening an additional location goes up. 00:02:53.721 --> 00:02:57.771 It's not just the direct monetary costs of paying 00:02:57.771 --> 00:02:59.436 for things like sprinklers. 00:02:59.436 --> 00:03:03.503 It's also the opportunity costs of the extra time and effort 00:03:03.503 --> 00:03:07.738 to file permits, manage the work and schedule inspections. 00:03:10.010 --> 00:03:12.977 A more stringent building code means a higher cost 00:03:12.977 --> 00:03:14.908 for opening up new businesses. 00:03:18.690 --> 00:03:21.020 And in turn, that higher cost can mean 00:03:21.294 --> 00:03:23.512 that fewer new businesses get opened. 00:03:30.000 --> 00:03:34.177 What's the right tradeoff between making buildings safer... 00:03:38.284 --> 00:03:40.928 and making it easier to launch new businesses? 00:03:45.148 --> 00:03:46.645 Once you see these tradeoffs, 00:03:46.645 --> 00:03:48.496 you'll find them everywhere you look -- 00:03:49.012 --> 00:03:50.230 healthcare, 00:03:55.130 --> 00:03:56.381 food, 00:04:02.264 --> 00:04:03.897 the environment. 00:04:08.747 --> 00:04:10.647 education. 00:04:14.908 --> 00:04:17.013 One more decision to consider -- 00:04:17.322 --> 00:04:19.123 if you're a teacher, should you spice up 00:04:19.123 --> 00:04:22.775 your economics class by checking out our free unit plan 00:04:22.775 --> 00:04:24.424 that uses this video?
