2. Scarcity & Opportunity Costs People have unlimited wants Resources to fulfill these wants are limited. Resources are land, labor, capital and entrepreneurship (factors of production) “Economizing Problem” 3/8/2016

3. Example of scarcity A teenager wants to go to a soccer game on Saturday night but also wants to catch up on late school assignments. The teenager encounters the scarcity of what???? TIME 3/8/2016

5. Opportunity Costs Individuals and society must choose between competing wants. They must make decisions Opportunity cost emphasizes that people are making choices. People choose to do one activity and the cost is giving up another activity 3/8/2016

6. Production Possibilities Curve (PPC) The PPC is drawn assuming that 1. Economy is operating efficiently 2. All resources (land, labor, capital, entrepreneurship) are fixed in quantity and quality as well as fully employed. 3. The technology is constant 4. Economy produces only two types of products 3/8/2016

8. Production Possibilities Curve (PPC) The shape of the PPC (bowed out or concave to the origin) determines the trade-off in the production of the two commodities What other shapes could the PPC take, and what do the shapes imply about the trade- off? If the factors of production were not fully utilized, where on the graph would an economy be? 3/8/2016

11. 4 Fundamental Questions Answered by Every Economy 1. What goods and services will be produced? 2. How will the goods and services be produced? 3. Who will get the goods and services? 4. How will the system accommodate change? 3/8/2016

12. Trade What would life be like if we could only consume the goods produced by the state we live in? How would production in the state change if each state had to be self- sufficient? It is individuals, not nations or states, that trade 3/8/2016

13. Absolute and Comparative Advantage Absolute advantage One individual or nation can produce more output with the same resources as another individual or nation Comparative advantage One individual or nation can produce a good at a lower opportunity cost than another 3/8/2016

20. Demand Curves Movement along a Demand Curve As price declines, the quantity increases As price rises, the quantity decreases “Inverse relationship” between price and quantity demand Shift in Demand Increase in demand is a shift to the right Decrease in demand is a shift to the left 3/8/2016

30. Bringing Demand and Supply together Equilibrium price The price in a competitive market at which the quantity demanded and the quantity supplied are equal Equilibrium quantity The quantity demand and supplied at the equilibrium price in a competitive market 3/8/2016

32. What happens if prices are above or below the equilibrium price? Shortage Excess demand; the amount by which the quantity demanded of a product exceeds the quantity supplied at a particular price Surplus Excess supply; the amount by which the quantity supplied of a product exceeds the quantity demanded at a specific price 3/8/2016

33. Activity 7 3/8/2016

34. Elasticity A measurement of how much one variable will change if another variable changes Price elasticity of demand Always negative Price elasticity of supply Always positive ***But, we look at the absolute value of the coefficient of elasticity and always talk about positive values*** 3/8/2016
