0:00:00.254,0:00:01.392 ♪ [music] ♪ 0:00:03.179,0:00:04.561 ♪ [music] ♪ 0:00:05.696,0:00:08.163 - [Tyler] Once you master [br]the economic way of thinking, 0:00:08.314,0:00:10.640 you'll see the world [br]in a very different way. 0:00:11.634,0:00:14.884 Two fundamental economic concepts [br]are everywhere you look -- 0:00:15.927,0:00:17.920 opportunity cost, 0:00:19.932,0:00:21.408 and tradeoffs. 0:00:24.288,0:00:27.032 Let's start with opportunity cost. 0:00:27.411,0:00:29.277 At this busy coffee shop, 0:00:30.117,0:00:33.088 opportunity costs lie [br]behind every decision. 0:00:34.281,0:00:37.818 Like for Jenny -- she's here [br]for her third date with Adam. 0:00:40.977,0:00:42.670 Was that a good decision? 0:00:43.146,0:00:46.463 After all, economics is [br]all about studying decisions. 0:00:46.563,0:00:49.666 Making a good decision is [br]about comparing the benefits 0:00:49.666,0:00:51.965 of that decision to the costs. 0:00:52.415,0:00:54.033 The obvious costs for this date, 0:00:54.033,0:00:57.697 for Jenny, were the Uber ride[br]she paid for to get here, 0:00:57.793,0:01:01.177 and her grande chai tea latte[br]with whole milk. 0:01:01.483,0:01:03.094 But what's missing? 0:01:03.094,0:01:04.643 Her opportunity cost. 0:01:05.047,0:01:09.329 Opportunity cost means the value [br]of the next best alternative. 0:01:09.472,0:01:12.956 For instance, instead of going[br]on her third date with Adam, 0:01:13.207,0:01:16.475 Jenny could've been binge watching[br]her favorite tv show. 0:01:16.955,0:01:19.423 She might've been [br]on a first date instead, 0:01:19.423,0:01:20.556 with Roman. 0:01:20.674,0:01:22.739 Or she might've been [br]having breakfast 0:01:22.739,0:01:24.423 with her very sweet sister. 0:01:26.073,0:01:27.616 Let's say her next best option 0:01:27.616,0:01:29.690 would've been [br]breakfast with her sister. 0:01:30.325,0:01:32.667 Does the benefit [br]of this third date with Adam 0:01:32.667,0:01:34.733 outweigh the opportunity cost? 0:01:35.265,0:01:38.298 It might seem strange [br]to think this way about romance, 0:01:38.298,0:01:41.999 and it doesn't mean that it's [br]about calculating every decision 0:01:41.999,0:01:43.561 down to the last penny. 0:01:43.743,0:01:46.942 Nonetheless, Jenny's time, [br]attention and energy -- 0:01:46.942,0:01:48.276 those are scarce. 0:01:51.076,0:01:53.850 And if she doesn't consider [br]the alternatives at all, 0:01:53.850,0:01:55.933 she might be wasting [br]parts of her life. 0:01:58.682,0:02:01.562 There's another [br]fundamental related concept 0:02:01.562,0:02:03.751 from economics -- tradeoffs. 0:02:04.585,0:02:06.939 Take these sprinklers [br]in the ceiling of the coffee shop, 0:02:06.939,0:02:08.004 for example. 0:02:09.273,0:02:11.982 Adding sprinklers can [br]make it safer during a fire, 0:02:12.069,0:02:15.018 but they also can cost [br]a lot of money to install. 0:02:16.685,0:02:19.986 How much cheaper would [br]the coffee be without them? 0:02:20.700,0:02:24.456 In a world of scarce resources,[br]one typically has to choose. 0:02:25.066,0:02:28.135 There's a tradeoff -- [br]safer buildings cost more, 0:02:28.135,0:02:30.910 but that means the coffee can [br]be more expensive. 0:02:37.886,0:02:40.796 The line is out the door here. 0:02:41.584,0:02:45.950 Perhaps the owner has considered[br]opening a second location. 0:02:47.329,0:02:50.126 As the building code, however,[br]becomes more stringent, 0:02:50.126,0:02:53.419 the cost of opening [br]an additional location goes up. 0:02:53.721,0:02:57.771 It's not just the direct [br]monetary costs of paying 0:02:57.771,0:02:59.436 for things like sprinklers. 0:02:59.436,0:03:03.503 It's also the opportunity costs[br]of the extra time and effort 0:03:03.503,0:03:07.738 to file permits, manage the work[br]and schedule inspections. 0:03:10.010,0:03:12.977 A more stringent building code [br]means a higher cost 0:03:12.977,0:03:14.908 for opening up new businesses. 0:03:18.690,0:03:21.020 And in turn, [br]that higher cost can mean 0:03:21.294,0:03:23.512 that fewer new businesses [br]get opened. 0:03:30.000,0:03:34.177 What's the right tradeoff[br]between making buildings safer... 0:03:38.284,0:03:40.928 and making it easier [br]to launch new businesses? 0:03:45.148,0:03:46.645 Once you see these tradeoffs, 0:03:46.645,0:03:48.496 you'll find them [br]everywhere you look -- 0:03:49.012,0:03:50.230 healthcare, 0:03:55.130,0:03:56.381 food, 0:04:02.264,0:04:03.897 the environment. 0:04:08.747,0:04:10.647 education. 0:04:14.908,0:04:17.013 One more decision to consider -- 0:04:17.322,0:04:19.123 if you're a teacher, [br]should you spice up 0:04:19.123,0:04:22.775 your economics class [br]by checking out our free unit plan 0:04:22.775,0:04:24.424 that uses this video?
