Problem 3 (5 points). Explain what the conditions are that an exchange must satisfy in order to make two individuals participate in it.

Problem 4 (10 points). Fab Tools Inc. can produce 150 widgets and 100 axes in a month. Another company AllMyTools Inc. can produce 80 widgets and 50 axes per month. Sketch the production sets and calculate the marginal costs.

Problem 5 (10 points). Suppose the seller’s opportunity cost of producing shirts is \$12 and the buyer’s valuation is \$22. If the seller gains \$2 more than the buyer from this transaction, what is the price at which the good is exchanged between the two parties?

Problem 6 (5 points). Define demand. Define supply. In your own words, explain the difference between demand and quantity demanded and supply and quantity supplied.

Problem 7 (10 points). The generalized demand function for good X is

Qd = 1,500 – 4P + 5A + 10M +3PY
