Concept Introduction:

Monetary Policy: This policy is used by the central bank to control the liquidity of money from an economy to bring the economy to a stable condition. This is done through management of interest rate and the money supply.

Expansionary Monetary Policy: This policy is used by the government to expand the money supply in the economy. Money supply is increased by reducing the interest rate, as lower interest rates will encourage people to borrow more.

Contractionary Monetary Policy: This policy is used by the government to contract the money supply from the economy. Money supply is reduced by increasing the interest rate, as higher interest rates will de-motivate people to borrow.

Inflationary gap: At the level of full employment, if the value of the real GDP is greater than the value of the potential GDP, it leads to emergence of inflationary gap.

Recessionary gap: At the level of full employment, if the value of the potential GDP is greater than the value of the real GDP, it leads to emergence of recessionary gap.

Suppose the marginal social cost of television sets is $100. This is constant and equal to the average cost of television sets. The annual demand for television sets is given by the following equation: Q = 200,000-500P, where Qis the quantity sold per year and P is the price of television sets. a) If television sets are sold in a perfectly competitive market, calculate the annual number sold. Under what circumstances will the market equilibrium be efficient? b) Show the losses in well-being each year that would result from a law limiting sales of television sets to 100,000 per year. Show the effect on the price, marginal social benefit, and marginal social cost of television sets. Show the net loss in well-being that will result from a complete ban on the sales of television sets. (show with graphs.)
