Consider the Phillips curve π_t = π_t-1 – 0.5(u_t – 0.01).

What is the natural rate of unemployment? Graph the short-run and long-run relationships between inflation and unemployment.

How much unemployment is necessary to reduce inflation by 3%? Compute the sacrifice ratio.

Do flexible exchange rates permit a country to pick its own unemployment-inflation trade-off target?

Expert Solution

The currencies are bought and sold in the foreign exchange market. The equilibrium price of foreign currency is determined through the demand and supply of home currency in the exchange market. The equilibrium price of a currency is called the fundamental value of a currency.

The exchange rate is the price of foreign currency in terms of home currency. There are two exchange rate: fixed and flexible. The fixed exchange rate is determined by the government of the country and the flexible exchange rate is determined by the demand and supply in foreign exchange market.

In case of fixed exchange rate the ability of monetary policy is limited. If the government uses the monetary policy to maintain the fundamental exchange rate at official exchange rate, it cannot use it to stabilize the economy. Thus, flexible exchange rate gives the government to use stabilization policy and let them choose the desired inflation and unemployment rate of the economy.

5. a. The Phillips curve is πt = πt^e+ (m + z) – αut Rewrite this relation as a relation between the deviation of the unemployment rate from the natural rate of unemployment (NRU), inflation and expected inflation. b. When we derived the natural rate of unemployment using the wage setting and price setting equations, what condition on the price level and expected price level was imposed in part a? c. How does the NRU vary with the markup? d....

Suppose the economy has the Phillips curve ?? = ??−1 − 0.5(?? − ?? ? ), where the natural rate of unemployment is given by the average of past two years’ unemployment: ?? ? = 0.5(??−1 + ??−2). (i) Why might the natural rate of unemployment depend on recent unemployment (as is assumed in the preceding equation)? [5] (ii) Suppose the Central bank follows a policy to reduce the inflation rate permanently by 1 per centage point. What effect will...

Consider the Phillips curve: pi(t) = Epi(t) - 0.5(u(t) - 8), where pi(t) is inflation rate at t, Epi(t) is expected inflation for t, and u(t) is unemployment at t. Now suppose the public has adaptive expectation: Epi(t) = pi(t-1), Epi(t+1) = pi(t), and so on. Inflation at time t-1 is pi(t-1) = 3%; the rate of unemployment u(t) at time t is at the natural level. The authorities decide to bring the unemployment rate to 6% from time t+1...

Suppose that the Phillips curve is given by:πt-πt-1=m+z-αut. In addition, you are told the following:

Suppose that the Phillips curve is given by:πt-πt-1=m+z-αut. In addition, you are told the following:If the unemployment rate is 0.07, the inflation rate will riseIf the unemployment rate is 0.10, the inflation rate will fallBased on this information, we can conclude that the natural rate of unemployment isA) lower than 0.07B) equals 0.07C) between 0.07 and 0.10D) higher than 0.10

A) What is the “Natural rate” of unemployment? B) Why is a movement up the Phillips curve (that is, a reduction in unemployment below the “natural rate” at the cost of higher inflation) untenable in the very long run? Explain using Aggregate Demand and Aggregate Supply. C) What can be done to shift the Phillips curve to the left?
