3. Unemployment, the Phillips Curve and Okun’s Law

Suppose the government of Exampleland is considering the introduction of a new trade policy that consists of rescinding existing free-trade agreements and imposing tariffs on imports.

a) If the Phillips Curve equation for this economy is ?_t = ?_t-1 + 0.03 - 0.5u_t before the new government policy, which of the following would be more likely to represent the new Phillips Curve after the policy is introduced, and why?

(i) ?_t = ?_t-1 + 0.02 - 0.5u_t

(ii) ?_t = ?_t-1 + 0.04 - 0.5u_t

This economy currently has an unemployment rate of 10% and is growing at a 2.6% annual rate. A high-ranking official in the treasury department is quoted in the newspaper as saying that next year's forecast GDP growth rate of 4.1% is expected to bring down the unemployment rate to 7% within a year. The same report also quotes an economist saying that the government's predictions are "highly unlikely" because they "fly in the face of decades of macroeconomic research.”

b) Who do you believe, and why?

Expert Solution

a) Phillips curve shows the negative relationship between inflation and unemployment. the ?t = ?t-1 + 0.03 - 0.5ut

Introduction of a new trade policy which imposes tariff will increase the price level of the good.

Now we know that increase in price level is nothing but the increase in inflation. So at the same unemployment rate, the new inflation will be higher than the previous level of inflation. So, the new equation of Phillips curve will be ?t = ?t-1 + 0.04 - 0.5ut

b) Current unemployment rate = 10%, Growth of unemployment = (du/u) * 100 % = 2.6%

From Okun's law, we can say that, ?Y/Y = 0.03 - 2?u

Now GDP growth rate is 4.1% i.e., ?Y/Y = 4.1%

Which means, 0.03 - 2?u = 4.1

or, 2?u = 0.03 - 4.1

or, 2?u = - 4.07

or, ?u = - 2.035

Now the current unemployment rate is 10%

If there is a decrease in unemployment rate by 2.035%, then the new unemployment rate is (10 - 2.035) = 7.965

which is higher than 7%.

So, it is not possible to cut down the unemployment rate to 7% within a year.

Suppose that the tradeoff between unemployment and inflation is determined by the Phillips curve: ??=???????(???????). In addition, suppose that the country involves two political parties, the Left and the Right. Suppose that the Left party always follows a policy of high money growth and the Right party always follows a policy of low money growth. What “political business cycle” pattern of inflation and unemployment would you predict under the following conditions? 1) Every four years, one of the parties takes...

Suppose that the Phillips curve is given by: ?? = ?? ? + ? − ??? where ?? is the inflation rate, ?? ? is the expected inflation, ?? is the rate of unemployment and, a and b are two positive parameters. Before the COVID-19 crisis, no wage contract was indexed to the inflation. After the crisis a fraction ? > 0 of wage contracts are indexed to inflation. a.

Suppose the Phillips curve is correct. If the government increases taxes, then aggregate demand decreases and unemployment falls in the short run Select one: True False According to the long-run Phillips curve, in the long run, unemployment depends upon factors such as fiscal and monetary policies that are designed to reduce cyclical unemployment. Select one: True False Proponents of rational expectations argued that if people expected a decrease in the money supply growth rate and inflation, then the decrease in...

A, B, C. Arthur Okun’s law identifies an inverse relationship between GDP and unemployment. Using the common U3 measure of unemployment, Okun found that the inverse relationship does not have a one-to-one ratio. Separately answering as parts A, B, and C, give and explain three different reasons why the ratio is not one-to one. Include the actual expected ratio based on reasons that you provide, as well. (note: You are not being asked to give reasons why the relationship is...
