This chapter explores the concept of opportunity costs and trade-offs involved in decision-making. It discusses how every choice, whether by individuals, businesses, or societies, comes with alternatives that must be sacrificed. Through the decision-making grid, readers can evaluate the benefits and costs of each option, exemplified by Karen's analysis of sleeping late versus waking up early to study. The importance of recognizing opportunity costs in daily choices emphasizes the impact of scarcity and the need for careful consideration in resource allocation.

Chapter 1 Section 2: Opportunity Costs
Trade offs • Alternatives that we give up whenever we choose one course of action over another • Individuals & trade offs • Every decision involves a trade off
Businesses & trade offs • Decisions that business people make about how to use land, labor, & capital resources also creates trade offs
Society & trade offs • Guns or butter • A country that decides to produce more military goods has fewer resources to devote to consumer goods & vice versa
Defining Opportunity Cost • Most desirable alternative given up as a result of a decision • Every ordinary decision that we make everyday involves an opportunity cost

Making the decision • With each new situation, the opportunity costs & benefits change • We always face opportunity costs • When we select one alternative, we have to sacrifice at least one alternative & forgo its benefits • By recognizing what we are sacrificing, we can decide whether the decision is worth it
Opportunity Cost: the foregone alternative Think: “next-best”

Thinking at the Margin • Many decisions involve adding one unit or subtracting one unit
Making a decision at the margin • When you decide how much more or less to do, you are thinking at the margin.
Cost & benefit at the margin • Such a comparison could help someone decide how much money to spend on a car, how many hours to work, & how much time to spend watching TV
Cost/Benefit Analysis • Decision makers just have to compare the opportunity costs & the benefits • What they will sacrifice & what they will gain • Once the opportunity cost outweighs the benefits, no more units should be added
