Daily Homework Assignment Guide

Notice that Daily Homework Assignments generally cover new material. They are designed to help you prepare for class so that class is more meaningful. You should read the new material before completing the homework questions. The assigned videos will also be very helpful as you complete these questions.

Daily homework assignments are graded on completion and correctness. Each is worth a maximum of 10 points. If everything is correct, you’ll receive all 10 points. If almost everything is correct and you completed everything, you’ll receive 9/10. If something is correct and you completed everything, you’ll receive 8/10. If nothing is correct but it’s clear that you made a good faith effort on everything, you’ll receive 7/10. ALWAYS give an attempt at everything. The penalty for incomplete work is high.

Note the “identifier” for each assignment. It tells you important information. The first number relates to the section from the course (1, 2 or 3). The letter tells you that it’s for Option A students. The number after the letter tells you the chapter. Some chapters have multiple assignments so they have an extra number. Assignment 1.A.1 is for Section 1, Option A students and covers chapter 1. Assignment 1.A.4.1 is for Section 1, Option A students and covers chapter 1 but because there’s an extra number at the end, you can expect another assignment from this chapter (1.A.4.2).

1. Describe the law of demand.

2. Describe the law of supply.

3. Draw a supply and demand diagram. Label each axis, the demand curve, the supply curve, the equilibrium price, and the equilibrium quantity.

1.A.6.

Read Chapter 6, Price Controls. Stop when you get to taxes.

In the last chapter, we learned how and why markets come to an equilibrium. In this chapter, we consider the impact of price controls. The law of supply and demand means that markets will always try to get to equilibrium. But when it can’t get there (like when there is a binding price control), it will get as close as possible. Before you start this assignment, make sure you read the part of section 6 that deals with price controls and pay careful attention to the difference between price floors and price ceilings and the difference between a binding and nonbinding price control (both for floors and ceilings).

Consider the following supply and demand schedule for the market for fast food workers. When there are price controls, please note that the price (the wage) charged in the market might not be the same as the equilibrium price (wage). Think about what price (wage) people will ACTUALLY earn and businesses will ACTUALLY pay in each of the situations described below.

 Supply Schedule Demand Schedule Price (Wage) QS Price  (Wage) QD 10 20 10 15 9 18 9 16 8 17 8 17 7 15 7 18 6 12 6 19 5 8 5 20

1.       What is the equilibrium price and quantity?

2.       Is the minimum wage an example of a price floor or a price ceiling?

3.       If the minimum wage were \$10, what wage would be charged in the market?

4.       If the minimum wage were \$10, what would be the quantity of labor supplied?

5.       If the minimum wage were \$10, what would be the quantity of labor demanded?

6.       If the minimum wage were \$10, what would be the quantity of labor hired?

7.       If the minimum wage were \$10, would there be a shortage, a surplus, or would the market clear?

8.       If the minimum wage were \$7, what wage would be charged in the market?

9.       If the minimum wage were \$7, what would be the quantity of labor supplied?

10.    If the minimum wage were \$7, what would be the quantity of labor demanded?

11.    If the minimum wage were \$7, what would be the quantity of labor hired?

12.    If the minimum wage were \$7, would there be a shortage, a surplus, or would the market clear?

1.A.7

1. What is the formula for consumer surplus, for producer surplus, and for total surplus?

2. Complete the table by calculating consumer surplus, producer surplus and total surplus for each of the following transactions.
Key: P = Price, WTP = willingness to pay, Cost = cost to produce

 Quantity Willingness to Pay Price Cost to Produce Consumer Surplus for this transaction Producer Surplus for this transaction Total Surplus for this transaction First good 10 6 4 Second good 8 6 5 Third good 6 6 6 Fourth good 4 6 7

3. Draw a generic supply and demand diagram (do NOT try to use the information from #1!). Label each axis, the demand curve, the supply curve, the equilibrium price, and the equilibrium quantity. Label the consumer surplus, producer surplus, and total surplus.

The most important thing about this chapter is that it teaches that the market outcome (the equilibrium) is efficient. Carefully read section 7-3b: Evaluating the market equilibrium. In a few sentences, explain why markets are efficient.

1.A.9

Using a supply and demand diagram, draw a graph for a small country that EXPORTS sugar. Be sure that you label the domestic supply, domestic demand, autarky (no trade equilibrium) price, and autarky (no trade equilibrium) quantity. Also, label the world price, quantity produced domestically under free trade, quantity consumed domestically under free trade, and the amount of sugar exported. Finally, label the gains to free trade.

3.A.17.2

Review chapter 17 and the handouts on game theory.

Use this information to complete the questions.

Susan and Kim have an assignment that they must do together. They will receive a joint grade on the assignment. The grade that they earn is dependent upon how hard each of them works on the assignment. If they both work hard, they’ll get an A. If one works hard and the other slacks off, they’ll get a B. If they both slack off, they’ll get a C.

Susan gets 50 units of happiness from an A, 40 units of happiness from a B and 30 units of happiness from a C. Susan finds that working hard on an assignment costs her 20 units of happiness.

Kim gets 60 units of happiness from an A, 40 units of happiness from a B and 20 unites of happiness from a C. Kim finds that working hard on an assignment costs her 10 units of happiness.

1. Complete the playoff matrix below.

 Kim Work Slack Susan Work Both work hard, they earn an A. Kim’s payout is 50 (60-10) Susan’s payout is 30 (50-20) Susan works hard. Kim slacks. They earn a B. Kim’s payout is:  Susan’s payout is: Slack Susan slacks. Kim _______. They earn a/an______.Kim’s payout is ____.  Susan’s payout is ____. Susan ______. Kim _____. They earn a/an _____.  Kim’s payout is ______.  Susan’s payout is _____.

2. Is work a dominant strategy for Kim? Why or why not?

3. Is slack a dominant strategy for Kim? Why or why not?

4. Is work a dominant strategy for Susan? Why or why not?

5. Is slack a dominant strategy for Susan? Why or why not?

6. Does this game have a Nash equilibrium? How can you tell? If it has one, what is it?
