            Suppose the mark-up is 12% and the wage-setting equation is W = P (1 – u), where u is the unemployment rate.

            i) What is the real wage, as determined by the price-setting relationship?

            ii) Define the natural rate of unemployment in this context and calculate it for this example.

iii) Suppose the markup of prices over costs decreases to 6%. Compute the natural rate of unemployment now and compare it to the one in ii)? If you find it to be different, explain the economic logic behind the change (increase or decrease).

Suppose the economy is characterised by the following equations: Price setting: P = (1+m) (W/A) Wage setting: W = Ae P e (1-u) where A is the unobserved and difficult to estimate technology parameter in the production function Y=AN, and Ae is its expected value. First suppose that expectations of both prices and technology are accurate. Solve for the natural rate of unemployment and medium-run real wage rate if the mark-up, m, is equal to 10 per cent and A...

3. An economy is characterized by the following price- and wage-setting equations: P = (1+m)(W/A) W = PeAe(1-u)a. Find the rate of unemployment if Pe=P but Ae does not necessarily equal A. Explain the effects of Ae/A on the unemployment rate. b. Now suppose that Pe=P and Ae=A. Solve for the natural rate of unemployment if the markup is equal to 0.05 .c. Does the natural rate of unemployment depend on productivity? Explain.

Suppose a country produces two goods: wine and cloth. Suppose that each cask of wine always requires 4 labor units and 1 capital unit in its production and each bolt of cloth requires 2 and 5 units respectively of labor and capital. This is regardless of the factor prices. (a) If wage and rental rate of capital each equal 100, what are the unit costs of wine and cloth? (b) Suppose wage and rental rate of capital are both 110,...

A6. The marginal propensity to consume (I) is the increase in disposable income from a $1 increase in consumer spending. (II) is the increase in consumer spending from a $1 increase in disposable income. (III) is usually a number between zero and one, but occasionally is a number greater than one. (IV) can be written as the change in consumer spending divided by the change in disposable income. (A) Statements I, III, and IV are all correct. (B) Statements II,...
