- Demand Supply Supply Demand LOANABLE FUNDS (Billions of dollars) Scenario 1: Individual Retirement Accounts (IRAS) allow people to shelter some of their income from taxation. Suppose the maximum annual contribution to such accounts is $5,000 per person. Now suppose there is an increase in the maximum contribution, from $5,000 to $8,000 per year. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of saving causes the equilibrium interest rate in the market for loanable funds to and the level of investment spending to Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period. Suppose the government repeals a previously existing investment tax credit. Shift the appropriate curve on the graph to reflect this change. The repeal of the previously existing tax credit causes the interest rate to and the level of investment to Scenario 3: Initially, the government's…arrow_forwardAssume the following: • Tax Rate (T) = 0.25Y Consumption (C) = $150 +0.9(YT) • Investment (1) = $200 Government (G) = $100 Exports (X) = $500 Imports (M) = 0.15Y If investment increases from $200 to $300 by how much will aggregate expenditures increase?

Initially, the interest income earned on bonds or deposits is taxed at a rate of 20%. Now suppose there is an increase in the tax rate on interest income, from 20% to 25%. Shift the appropriate curve on the graph to reflect this change. This change in the tax treatment of interest income from saving causes the equilibrium interest rate in the market for loanable funds to and the level of investment spending to Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period.
