Chapter 1.2: Opportunity Cost

Slide 2 Copyright © Pearson Education, Inc.Chapter 1, Opener Bell Ringer Think of a recent decision you made and what was the alternative decision you could have chosen.

Slide 3 Copyright © Pearson Education, Inc.Chapter 1, Opener Trading time! Take out the product you brought from home Must trade with at least two people Can’t end up with your own product Time to trade!

Slide 4 Copyright © Pearson Education, Inc.Chapter 1, Opener Trade-offs Trade-offs involve things easily measured: money, property or time. Trade-off The act of giving up one benefit to gain another, greater benefit. But often they involve values that are hard to measure: Enjoyment Job satisfaction Feeling of well-being

Slide 5 Copyright © Pearson Education, Inc.Chapter 1, Opener Trade-offs Individuals and trade-offs –Give me examples Businesses and trade-offs –Give me examples Governments and trade-offs –Give me examples –“Guns or butter”- The choice between spending money on military or domestic needs

Slide 6 Copyright © Pearson Education, Inc.Chapter 1, Opener Determining Opportunity Cost We always have to make decisions and make trade-offs. Of all our trade-offs, one of those rejected alternatives is more desirable than the rest. This is known as the “opportunity cost” (definition to come)

Slide 7 Copyright © Pearson Education, Inc.Chapter 1, Opener Opportunity Cost Think of opportunity cost as the value of what you are giving up…not what you are giving up. Opportunity Cost The most desirable alternative given up as the result of a decision The benefits you could have received from the other action is the O.C.

Slide 13 Copyright © Pearson Education, Inc.Chapter 1, Opener Paper folding activity

Slide 14 Copyright © Pearson Education, Inc.Chapter 1, Opener Thinking at the Margin Many decisions involve adding or subtracting one unit – one hour, one dollar Thinking at the margin Deciding whether to do or use one additional/less unit of some resource From an economist’s point of view, when you decided how much to fold the paper, you were “thinking at the margin”

Slide 15 Copyright © Pearson Education, Inc.Chapter 1, Opener Cost/Benefit Analysis Deciding by “thinking at the margin” is just like making any other decision When we make decisions we think of the opportunity costs and the benefits- what we will sacrifice and what we gain from our decision.

Slide 16 Copyright © Pearson Education, Inc.Chapter 1, Opener Cost/Benefit Analysis We always want to make the best decision – that’s what we are programmed to do! Cost/benefit analysis A decision-making process in which you compare what you will sacrifice and gain by your action

Slide 17 Copyright © Pearson Education, Inc.Chapter 1, Opener Marginal Cost- The extra cost of adding one unit Marginal Benefit- The extra benefit of adding one unit
