Trade-offs and Opportunity CostALL decisions involve trade-offs.
The most desirable alternative given up as a result of a decision is known as opportunity cost.
Trade-offs are all the alternatives that we give up whenever we choose one course of action over others.
(Examples: going to the movies)
What are trade-offs of deciding to go to college? What is the opportunity cost of going to college?

Every society must answer three questions:
The Three Economic Questions1. What goods and services should be
produced? 2. How should these goods and services be
produced? 3. Who consumes these goods and services?
The way these questions are answered determines the economic system
An economic system is the method used by a society to produce and distribute goods and
services. 8

What Causes a Shift in Demand?
5 Shifters (changers) of Demand:
1.Tastes and Preferences2.Related Goods price3.Income4.Consumer population5.Expectations of the future
TRICE
Changes in PRICE don’t shift the curve. It only causes movement along the curve. 9

DEMAND DEFINEDWhat is Demand?
What is the Law of Demand?
The law of demand states There is an INVERSE relationship between price and quantity demanded

Scarcity vs. Shortages
•Shortages occur when producers will not or cannot offer goods or services at current prices. Shortages are temporary.
•Scarcity occurs at all times for all goods.
Price vs. CostWhat’s the price? vs. How much does that cost?
Price= Amount buyer (or consumer) pays
Cost= Amount seller pays to produce a good
InvestmentInvestment= the money spent by BUSINESSES to improve their production
Ex: $1,000 new computer, $1 Million new factory 11

Supply DefinedWhat is supply?Supply is the different quantities of a good that sellers are willing and able to sell (produce) at different prices.
What is the Law of Supply?There is a DIRECT (or positive) relationship between price and quantity supplied.
•As price increases, the quantity producers make increases•As price falls, the quantity producers make falls.
Why? Because, at higher prices profit seeking firms have an incentive to produce more.
EXAMPLE: Mowing Lawns13

6 Determinants (SHIFTERS) of Supply1. Prices/Availability of inputs (resources)2. Number of Sellers3. Technology4. Government Action: Taxes & Subsidies
5. Opportunity Cost of Alternative Production
6. Expectations of Future ProfitChanges in PRICE don’t shift the curve. It only
causes movement along the curve. 28

Hamburgers1. Mad cow disease kills 20% of cows 2. Price of burgers increase 30%3. Government taxes burger producers4. Restaurants can produce burgers and/or tacos. A demand
increase causes the price for tacos to increase 500%5. New bun baking technology cuts production time in half6. Minimum wage increases to $10
