Chapter 1: What’s in Economics for you? (Scarcity, Opportunity Cost, and
Economics: How individuals, businesses, and governments make the best possible
choices to get what they want, and how these choices interact in the market.
Scarcity: The problem that arises because we all have limited; money, time. And
-Scarcity means every choice involves a trade-off
-Every dollar you spend involves choice, and because of scarcity it must be a smart
Opportunity Cost: Cost of best alternative given up.
-Opportunity Cost is the key to mutual benefits from trade.
-In weighing the benefits and costs of any decision, we compare what we get from each

is what we have to give up to get it.
Incentives: Rewards and penalties for choice
Voluntary Trade: With voluntary trade, each person feels that what he or she gets

Absolute Advantage: Ability to produce a product at a lower absolute cost than
Comparative Advantage: Ability to produce a product at a lower opportunity cost
than another producer.
-To determine comparative advantage it is best to use opportunity cost and measure it
per unite of the product chosen.
Opportunity Cost = Give Up
-Opportuity cost of any choice is the value of the fork in the rode not taken -Voluntary tade is not a zero-sum game, whre one persons gain is the others loss. Both
traders gain. Mutualy bennifical gains from trade are caused by differnece in
comparative advantage. Absolute advantage Is not important.
