Answer to Problem 1P

a. Policy used by the policy makers in Japan to promote growth.

  • From the data, it is concluded that the policy maker used expansionary monetary policy as well as fiscal policy.
  • Short term interest rate has decreased from 7.38% in 1991 to 0.04% in 2003. This indicates that the policy used is expansionary monetary policy.

Explanation of Solution

  • Government debt as a percentage of GDP rose from 64.8% in 1991 to 157.5% in 2003. And the government deficit has also increased from 1.81% to 7.67%.
  • This indicates the use of expansionary fiscal policy by the policy makers.Thus, the policy makers used expansionary fiscal and monetary policy to promote growth.

b. Situation of liquidity traps.

  • It is a situation of liquidity trap in an economy. When the interest rate is very low, almost equal to zero, the monetary policy loses its effectiveness.
  • People prefer to keep money in the form of cash rather than bond or deposits.Thus, in the case of liquidity trap, monetary policy is ineffective.

  • The change in expenditure or tax is reflected as the change in real GDP.
