Assume that the economy is at long run equilibrium,with unemplyment at 5% and inflation at 2%pa.

Suppose a shock causes a very large increase in the cost of crude oil and gas. Assume that Ireland does not produce any oil or gas, and imports large amounts of oil and gas. The shock causes unemployment to rise to 9%, and inflation to rise to 4%pa.

(a) Using a large AD/AS diagram and a large Phillips curve diagram, illustrate the short-run effects of this shock on the Irish economy.

[assume that the oil cost shock causes v= 4%, that the price level is not sticky, and that beta symbol= 0.5 in the Phillips curve equation]

(b) Describe and illustrate a policy response that might help return the economy to its long-run equilibrium.

A monopoly firm sells its product to two countries: A and B. Demand in the two countries are QA = 100 – 2p and QB = 80 – p. Firm’s cost function is C = 100 + 10Q. Find the firm’s total profit and the prices it charges in the two countries.

Your textbook (Microeconomics 9th Edition) gives 3 “motives” for holding money. Please list one of these motives and give an example, not the definition, of why you might hold money using the rationale of motive that you have selected.

Consider the following two demand segments: 120−4Q = P and 100−4Q = P assuming there’s a constant marginal cost to serving either group, C(Q) = 60Q.

1. Find the optimal price, quantity and profits when the firm is able to practice third degree price discrimination.

2. Find the optimal price, quantity and profits when the firm is unable to practice third degree price discrimination.

3. Compute the price elasticity of demand associated with each optimal monopoly output in each segment. Do these results match what we would expect?

Suppose there are two types of demanders, casual: P = 500 − Q and hardcore: P = 500 − 0.5Q; while the cost to serve all consumers is given by C(Q) = 200Q. For simplicity, we’ll assume there is just a single consumer of each type.

1. Find the optimal two part pricing scheme when all prospective customers must be offered the same fixed access fee and per-unit price.

2. Find the optimal two part pricing scheme when the firm is able to treat each demand segment as distinct from the other and therefore may offer a different access fee and per-unit price to each group.
