4. Consider a closed economy of AU land that can be described by the following functions:All values C, I, and G are in billions of USD.Investment expenditure: lg 500 -50r, where r is real interest rate(in percent) = 3%Government expenditure: G = 125Lump-sum constant taxes: T = 100(a) Find the equilibrium Y, C and IgConsumption expenditure: C = 100 +0.75(Y-T)6.lintiitch (b) The Bank of Thailand (BOT) has recently announced that consumer confidence inThailand fell. Let the decrease in consumer confidence to be equal to 10 points,from 100 to 90, so now C= 90+0.75(Y-T). Find the new equilibrium Y.(c) Suppose the Bank of Thailand (BOT) is trying to reverse this adverse effect on theeconomy. The Bank of Thailand (BOT) can cut the interest rate in order to stimulateinvestment spending (Ig). The increase in Ig has to be sufficient to push the overall Ylevel back to the original Y level that you have found in part (a). Solve for this newinterest rate. Please leave it as a percent with two decimal places.(d) Based upon your answer in part (c), what should the central bank do with the discountrate (DR) to achieve the target real interest rate? Also, what is the type of such amonetary policy?

Suppose that conditions in the economy are such that the after-tax expected real interest rate is described by the equationRa = a X gWhere a is a number that depends on how people value their consumption in one period compared with another period, and g is the growth rate of the economy.

Assume that GDP (Y ) is 5,000 in a closed economy. Consumption (C) is given by the equationC = 1,200 + 0.6(Y −T)−100r, where r is the real interest rate, in percent. Investment (I) is givenby the equation I = 2,000 − 200r. Taxes (T) are 1,000, and government spending (G) is 1,500.(a) What are the equilibrium values of C, I, and r? (b) What are the values of private saving, public saving, and national saving? (c) For the given consumption function, what does the relationship between consumption and theinterest rate imply about the saving schedule?

Assume a closed economy with no government and a fixed aggregate price level and constant interest rate. Furthermore, assume that the country's consumption function is C = 200 + 0.75YD, where YD is disposable income, and C is consumption, and that planned investment is $75. What will happen if aggregate wealth decreases by $100, all else equal? a. The aggregate spending line will shift downward. b. The income–expenditure equilibrium real GDP will increase by more than $100. c. There will be no multiplier effect on real GDP, since there is a drop in aggregate wealth. d. Planned investment will increase.
