Document Summary

Purpose: demonstrate that competitive markets tend to equilibrium over time without any external guidance or co-ordination between buyers and sellers, see how shifts in demand or supply affect equilibrium outcomes, have some fun! We will be playing a game in tutorials this week. To prepare (and help you play better), i suggest: complete the questions below, review the instructions for moblab"s competitive market game: https://moblab. wistia. com/medias/8a685i5xwv. Note: not all problems will be taken up in tutorial; nor will solutions for these problems be posted: the market for oranges: assume the market demand curve for oranges is (cid:1843)(cid:4666)(cid:1842)(cid:4667)= 1(cid:2872)9(cid:2871) (cid:2871) and the market supply curve for oranges is (cid:1843)(cid:4666)(cid:1842)(cid:4667)=(cid:2873) 9. Find the new equilibrium price and quantity for oranges.

Look at the two tables below, which show, respectively, the willingness to pay and willingness to accept of buyers and sellers of bags of oranges. For the following questions, assume that the equilibrium price and quantity will depend on the indicated changes in supply and demand. Assume that the only market participants are those listed by name in the two tables.

Consumers			Producers
Person	Maximum Price Willing to Pay	Actual Price (Equilibrium Price)	Person	Minimum Acceptable Price	Actual Price (Equilibrium Price)
Bob	$16	$10	Carlos	$5	$10

Bill	13	10	Chuck	7	10
Bart	12	10	Cindy	8	10
Brent	11	10	Craig	9	10
Betty	10	10	Chad	10	10

a. Given the equilibrium price of $10, what is the equilibrium quantity given the data above?

c. Assume that we are back to talking about bags of oranges (a private good), but that the government has decided that tossed orange peels impose a negative externality on the public that must be rectified by imposing a $3-per-bag tax on sellers.

What is the new equilibrium price? $

What is the new equilibrium quantity?

Show these data graphically. Upon what speciﬁc assumptions is this production possibilities curve based? b. If the economy is at point C, what is the cost of one more unit of capital good? Of one more unit of consumer good? Explain how the production possibilities curve reﬂects the law of increasing opportunity costs. c. If the economy characterized by this production possibilities table and curve were producing 7 units of capital goods and 45 units of consumer goods, what could you conclude about its use of its available resources? d. What would production at a point outside the production possibilities curve indicate? What must occur before the economy can attain such a level of production? e. Assume consumer good are bread and cookies here. What happens to this frontier if disease kills half of the economy’s hens and cows? Q 2(a): How does self-interest help achieve society’s economic goals? Why is there such a wide variety of desired goods and services in a market system? In what way are entrepreneurs and businesses at the helm of the economy but commanded by consumers? b. Why is private property, and the protection of property rights, so critical to the success of the market system? c. How the market system decides what to produce, how to produce it, and who obtains it. Q 3: How will each of the following changes in demand and/or supply affect equilibrium price and equilibrium quantity in a competitive market; that is, do price and quantity rise, fall, or remain unchanged, or are the answers indeterminate because they depend on the magnitudes of the shifts? Use supply and demand diagrams to verify your answers. i. Supply decreases and demand is constant. ii. Demand increases and supply increases. iii. Supply increases and demand decreases. b. Explain why the price in competitive markets settles down at the equilibrium intersection of supply and demand. Explain what happens if the market price starts out too high or too low. c. Consider the following events: Scientists reveal that consumption of oranges decreases the risk of Corona Virus and, at the same time, farmers use a new fertilizer that makes orange trees more productive. Illustrate and explain what effect these changes have on the equilibrium price and quantity of oranges.
