9:59:59.000,9:59:59.000 - [Tyler] Once you master [br]the economic way of thinking, 9:59:59.000,9:59:59.000 you'll see the world [br]in a very different way. 9:59:59.000,9:59:59.000 Two fundamental economic concepts [br]are everywhere you look -- 9:59:59.000,9:59:59.000 opportunity costs, and tradeoffs. 9:59:59.000,9:59:59.000 Let's start with opportunity costs. 9:59:59.000,9:59:59.000 At this busy coffee shop, 9:59:59.000,9:59:59.000 opportunity costs lie [br]behind every decision. 9:59:59.000,9:59:59.000 Like for Jenny -- she's here [br]for her third date with Adam. 9:59:59.000,9:59:59.000 Was that a good decision? 9:59:59.000,9:59:59.000 After all, economics is [br]all about studying decisions. 9:59:59.000,9:59:59.000 Making a good decision is [br]about comparing the benefits 9:59:59.000,9:59:59.000 of that decision to the costs. 9:59:59.000,9:59:59.000 The obvious costs for this date 9:59:59.000,9:59:59.000 for Jenny were the Uber ride[br]she paid for to get here, 9:59:59.000,9:59:59.000 and her grande chai tea latte[br]with whole milk. 9:59:59.000,9:59:59.000 But what's missing? 9:59:59.000,9:59:59.000 Her opportunity cost. 9:59:59.000,9:59:59.000 Opportunity cost means the value [br]of the next best alternative. 9:59:59.000,9:59:59.000 For instance, instead of going[br]on her third date with Adam, 9:59:59.000,9:59:59.000 Jenny could've been binge watching[br]her favorite tv show. 9:59:59.000,9:59:59.000 She might've been [br]on a first date instead, 9:59:59.000,9:59:59.000 with Roman. 9:59:59.000,9:59:59.000 Or she might've been [br]having breakfast 9:59:59.000,9:59:59.000 with her very sweet sister. 9:59:59.000,9:59:59.000 Let's say her next best option 9:59:59.000,9:59:59.000 would've been [br]breakfast with her sister. 9:59:59.000,9:59:59.000 Does the benefit [br]of this third date with Adam 9:59:59.000,9:59:59.000 outweigh the opportunity cost? 9:59:59.000,9:59:59.000 It might seem strange [br]to think this way about romance, 9:59:59.000,9:59:59.000 and it doesn't mean it's [br]about calculating every decision 9:59:59.000,9:59:59.000 to the last penny. 9:59:59.000,9:59:59.000 Nonetheless, Jenny's time, [br]attention and energy -- 9:59:59.000,9:59:59.000 those are scarce. 9:59:59.000,9:59:59.000 And if she doesn't consider [br]the alternatives at all, 9:59:59.000,9:59:59.000 she might be wasting [br]parts of her life. 9:59:59.000,9:59:59.000 There's another [br]fundamental related concept 9:59:59.000,9:59:59.000 from economics -- tradeoffs. 9:59:59.000,9:59:59.000 Take these sprinklers [br]in the ceiling of the coffee shop, 9:59:59.000,9:59:59.000 foe example. 9:59:59.000,9:59:59.000 Adding sprinklers can [br]make it safer during a fire, 9:59:59.000,9:59:59.000 but they also can cost [br]a lot of money to install. 9:59:59.000,9:59:59.000 How much cheaper would [br]the coffee be without them? 9:59:59.000,9:59:59.000 In a world of scarce resources,[br]one typically has to choose. 9:59:59.000,9:59:59.000 There's a tradeoff -- [br]safer buildings cost more, 9:59:59.000,9:59:59.000 but that means the coffee can [br]be more expensive. 9:59:59.000,9:59:59.000 The line is out the door here. 9:59:59.000,9:59:59.000 Perhaps the owner has considered[br]opening a second location. 9:59:59.000,9:59:59.000 As the building code however[br]becomes more stringent, 9:59:59.000,9:59:59.000 the cost of opening [br]an additional location goes up. 9:59:59.000,9:59:59.000 It's not just the direct [br]monetary costs of paying 9:59:59.000,9:59:59.000 for things like sprinklers. 9:59:59.000,9:59:59.000 It's also the opportunity costs[br]of the extra time and effort 9:59:59.000,9:59:59.000 to file permits, manage the work[br]and schedule inspections. 9:59:59.000,9:59:59.000 A more stringent building code [br]means a higher cost 9:59:59.000,9:59:59.000 for opening up new businesses. 9:59:59.000,9:59:59.000 And in turn, [br]that higher cost can mean 9:59:59.000,9:59:59.000 that fewer new businesses [br]get opened. 9:59:59.000,9:59:59.000 What's the right tradeoff[br]between making buildings safer... 9:59:59.000,9:59:59.000 and making it easier [br]to launch new businesses? 9:59:59.000,9:59:59.000 Once you see these tradeoffs, 9:59:59.000,9:59:59.000 you'll find them [br]everywhere you look -- 9:59:59.000,9:59:59.000 healthcare, 9:59:59.000,9:59:59.000 food, 9:59:59.000,9:59:59.000 the environment. 9:59:59.000,9:59:59.000 education. 9:59:59.000,9:59:59.000 One more decision to consider -- 9:59:59.000,9:59:59.000 if you're a teacher, [br]should you spice up 9:59:59.000,9:59:59.000 your economics class [br]by checking out our free unit plan 9:59:59.000,9:59:59.000 that uses this video? 9:59:59.000,9:59:59.000 If you're a learner, [br]should you watch another MRU video? 9:59:59.000,9:59:59.000 Well, YouTube is full [br]of entertaining videos, 9:59:59.000,9:59:59.000 [cat meows] 9:59:59.000,9:59:59.000 but please, of course, consider[br]the opportunity costs.
