1.Suppose that the federal government has a budget deficit and the economy is closed. Using the savings–investment spending identity, explain how this affects investment spending.

2.The market for loanable funds is in equilibrium. All else equal, the federal government has eliminated taxes on interest earned from savings. Describe how this will affect the market for loanable funds, the equilibrium interest rate, and the equilibrium quantity of loanable funds.

Expert Solution

(1)

A budget deficit increases government borrowing for deficit financing. Since investment represents the demand for borrowing, higher borrowing increases investment, shifting investment curve to right, increasing interest rate and equilibrium investment (and savings).

In following graph, I0 and S0 are initial investment and saving curves, intersecting at point A with initial interest rate r0 and equilibrium investment & savings Q0. Higher investment shifts I0 right to I1, intersecting s0 at point B with higher interest rate r1 and higher investment & savings Q1.

(2)

Zero tax on interest income will incraese savings, shifting supply curve of loanable funds rightward, decreasing interest rate and increasing quantity of loanable funds.

In following graph, D0 and S0 are initial demand and supply curves for loanable funds, intersecting at point A with initial interest rate r0 and quantity of loanable funds Q0. Higher savings shifts S0 right to S1, intersecting D0 at point B with lower interest rate r1 and higher quantity of loanable funds Q1.

Question 2 Consider a small closed economy. The government wants to reduce the budget deficit by reducing its spending. a. Use the goods market and IS curve to illustrate graphically the impact of the reduction in government spending on output. b. Now use the goods market and money market diagrams and the IS-LM model to illustrate graphically the impact of the reduction in government spending on output c. Why the effect of the reduction in government spending on output is...

Suppose that the federal government begins to run a large budget deficit at a time when many productive resources are idle factories are operating far below capacity in most industries, and there are surplus of labour in almost every area of the economy. How might the existence of all these idle resources prevent even a very large increase in government borrowing from leading to an increase in interest rates? If you found part (a) hard to answer, ask yourself whether...

The U.S. is a large economy with a trade deficit. Suppose the U.S. federal government increases income tax. How will this policy affects the U.S. saving, investment, real interest rate, and capital flows? Is it possible to prevent changes due to this tax policy? If yes, how? Explain reasoning.

Effects of a government budget deficit Consider a hypothetical open economy.

Effects of a government budget deficit Consider a hypothetical open economy. The following table presents data on the relationship between various real interest rates and national saving, domestic investment, and net capital outflow in this economy, where the currency is the U.S. dollar. Assume that the economy is currently experiencing a balanced government budget.Given the information in the preceding table, use the blue points (circle symbol) to plot the demand for loanable funds. Next, use the orange points (square symbol)...

And suppose that, if at full employment, the economy would produce an output and income of 3200By how much would the government need to raise spending (G) to bring the economy to full employment?7Suppose a closed economy with no government spending which in equilibrium is producing an...
