Note: In your final expression for Y, restrict coefficient values to three decimal points. (c) Suppose government spending is 1200 , money supply by the Central Bank is 900 and the price level is 1, find the value of GDP (Y) and equilibrium interest rate (R) for Sunderland. Income Identity Consumption function Investment function Government Expenditure Net export function Money market equilibrium (2)The questions in this section are related to the macroeconomic model of Sunderland.

O a contraction. O a slump. O All of these. QUESTION 17 Dean borrows $400 from Tim. Tim wants to make a 10% real return on his money, so they both agree on a 10% interest rate paid next year. Dean and Tim did not anticipate any inflation, yet the actual inflation turned out to be 4% next year. In this case, O Dean is better off. O Tim will receive more than 10% of real rate of return a year from now. O Dean will pay $56 a year from now on. Tim is better off.

(b) Assume that the government increases spending by 20%. Calculate the new goods market equilibrium. What is the multiplier for the change in government spending? Assume now that the country starts trading globally and has Exports and Imports. Assume that imports are given by Im = n Y, with n being the marginal propensity to import. (e) Explain why - with exports and imports - a increase in government spending (e.g., 20%) results in a smaller change in aggregate demand/income in equilibrium than without exports and imports. (You do not have to calculate the new equilibrium.)
