Chapter - The Phillips Curve

1. The Original Phillips Curve
(a) Show the equation of the original Phillips Curve
(b) What is the main relationship this equation implies? Also, please give a numerical example of the implication.
(c) In the historical context, before 1970s, why expected inflation has no role here? (Πte = 0)
(d) What are the main reasons that caused the original Phillips Curve invalid since the 1970s?

Chapter - Openness in Goods and Financial Markets

1. The Real Exchange Rate
Suppose the United States produced one good, Dell Laptop, and Japan also produced only one good, Sony Laptop. Dell Laptop costs $1,000 in the US and Sony Laptop costs Y138,000 in Japan. One dollar is worth Y115. Please work in details on the real exchange rate between the US and Japan. Which laptop is cheaper? by how much?

2. Interest Parity Condition
Suppose the interest parity condition holds. Also assume that the one-year interest rate in the US is 5% and the one-year interest rate in Canada is 6%.

(b) Suppose output is below the natural level of output. In a fixed exchange rate regime, using AS-AD diagram and explain how the economy can return to the natural level of output.

(c) Suppose the economy is operating below the natural level of output. Use the AS-AD diagram and discuss the arguments for and against using a devaluation in such a situation.

Chapter - Solow Growth Model

1. Original Solow Growth Model

(b) Graphically illustrate the functions of depreciation and investment per worker. In your graph, clearly label all curves, steady state and equilibria.

(c) Suppose depreciation per worker is less than saving per worker. Given this situation, explain what will happen to each of the following variables over time: capital per worker, output per worker, saving per worker, and consumption per worker.

(d) Suppose depreciation per worker is more than saving per worker. Given this situation, explain what will happen to each of the following variables over time: capital per worker, output per worker, saving per worker, and consumption per worker.

(e) Suppose there is an increase in the saving rate. Explain what effect this will have on output, output per worker, the rate of growth of output, and the rate of growth of output per worker. Also, graphically illustrate and explain the effects of an increase in the saving rate on the Solow growth model. In your graph, clearly label all curves and equilibria.

2. Solow Growth Model with Technological Progress

(b) Graphically illustrate the functions of required investment, output and investment per effective worker. In your graph, clearly label all curves, balanced growth and equilibria.

(c) Suppose there is an increase in the saving rate. Explain what effect this increase in the saving rate will have on the rate of growth of output per worker. Also, graphically illustrate and explain the effects of an increase in the saving rate on the Solow growth model. In your answer, you must clearly label all curves and the initial and final equilibria. In your answer, explain what happens to the rate of growth of output per worker and the rate of growth of output as the economy adjusts to this increase in the saving rate.
