2 What do you think is the market price for renting an apartment in Plainfield? What happens to the quantity of demand and supply after the price change? List four outcomes that would most likely occur if the price was set there Think like an economist!

3 Price Ceiling Maximum price that can be legally charged for a good or service It s called binding if the ceiling price is set below market equilibrium It s not binding if it s set above market equilibrium

6 Rent Control (Price ceiling) Allows people to live in neighborhoods they could not afford Causes a shortage of apartments Causes bad quality apartments Property value in surrounding area s can decline Causes deadweight loss!

7 What do you think the average wage is for a cashier at a Plainfield Target? What happens to the quantity of demand and supply after the wage change? List four outcomes that would most likely occur if the price was set there Think like an economist!

8 Price Floors Minimum price that is set that must be paid for a good or service It is called binding if the floor price is set above market equilibrium It s not binding if it s set below market equilibrium

11 Minimum Wage (price floor) Minimum price that an employer can pay a worker for an hour of labor Increases worker s income Can cause a surplus of workers Younger people may not be hired for low skilled jobs Many, many, many more outcomes

12 National & Illinois Minimum Wage National = $7.25 Illinois = $8.25 Is that enough or even needed?

13 TAXES! Why do I tax all the time?

14 How Taxes Affect Market Outcomes Market not efficient Total surplus not maximized When a good is taxed, the quantity sold is smaller. Buyers and sellers share the tax burden.

15 Tax incidence When the burden of a tax is shared among participants in a market

16 If there is a sales tax on buying these candy worms, it s not just the kid with worms who feels the burden of the tax

17 CANDY WORM MARKET Price Qd Qs $ $ $ $ $

18

19 Let s say there is a $0.50 tax on buying candy worms 3 questions must be answered to figure out the tax incidence Question 1: Does the tax affect the supply curve or the demand curve? Question 2: Which way does the curve shift? Question 3: How does the shift affect equilibrium?

20 What happens if there is a $0.50 tax on the buyer? P S1 D 1 Q

21 Your turn

22 Assume the government wants to reduce the amount of sugar Americans are consuming. So, they enforce a excise tax of $1.00 for every candy worm produced. 3 questions must be answered to figure out the tax incidence Question 1: Does the tax affect the supply curve or the demand curve? Question 2: Which way does the curve shift? Question 3: How does the shift affect equilibrium?

23 What happens if there is a $1.00 tax on the seller? P S1 D 1 Q

24 Elasticity and Tax Incidence In what proportions is the burden of the tax divided? How do the effects of taxes on sellers compare to those levied on buyers? The answers to these questions depend on the elasticity of demand and the elasticity of supply.

25 How the Burden of a Tax Is Divided (a) Elastic Supply, Inelastic Demand Price Price buyers pay 1. When supply is more elastic than demand... Supply Price without tax Price sellers receive Tax the incidence of the tax falls more heavily on consumers than on producers. Demand 0 Quantity

26 How the Burden of a Tax Is Divided Price Price buyers pay (b) Inelastic Supply, Elastic Demand 1. When demand is more elastic than supply... Supply Price without tax Tax than on consumers. Price sellers receive the incidence of the tax falls more heavily on producers... Demand 0 Quantity

36 Luxury Tax In 1990, Congress adopted a new luxury tax on items that only the rich could afford. The goal of this tax is to raise revenue from those who could easily afford to pay Answer this question: Does the price incidence truly affect buyers more? Write a short answer and provide a supply and demand curve to further explain your answer.

37 Market Efficiency vs. Efficiency Loss

38 Market Efficient Basics Total surplus consumer surplus + producer surplus So, when do you think a market is most efficient? When total surplus is maximized!

39 Measuring surplus on a graph Consumer surplus The area below the demand curve and above the price Producer surplus The area above the supply curve and below the price

40 Consumer and Producer Surplus in the Market Equilibrium Price A D Supply Total Surplus Equilibrium price Consumer surplus Producer surplus E Can you label: -Consumer surplus - Producer surplus - Total surplus B Demand C 0 Equilibrium Quantity quantity

41 Efficiency Loss Also known as deadweight loss or welfare loss Total surplus is NOT maximized Resources and products are underutilized Many causes Government Regulations Externalities Monopoly pricing

43 UTILITY We are not talking about us!

44 Market Efficiency Basics What do you think happens to the utility of this good after you Utility consume more and more of it? The amount of satisfaction or benefits one gets out of consuming a good.

45 Market Efficiency Basics Diminishing marginal utility There will be a decline in utility with each additional unit consumed Holy pizza! My utility from each slice of pizza really started to decline.think I ll just order a small pizza next time.

46 Market Efficiency Basics Utility maximization rule Maximize your marginal utility with each dollar you spend You do this by weighing your marginal utility per dollar spent $1 Slice of Pizza Total Utility Marginal Utility
