We use the following terminology in this part: aggregate income Y and disposable income Ya (= Y –T), consumption function C(Y4), planned investment function I(r), government spending G, and taxation T = tY where t is the marginal tax rate; r% denotes the real interest rate in the economy. (Note, r is in percentage points, e.g. r = 2 means the interest rate is 2%. When doing calculations, the interest rate should not simply be inserted in decimal form. For example, if r = 2 then I(2) = 124 – 2 = 122.) Consider a hypothetical economy where: • C(Ya) = 12 + 0.75 × (Y – T) • I(r) = 124 – 1 ×r • G = 120 • t = 20%

In a simple model without government spending or taxation, if C = a +bY where C is consumer spending and Y is GDP which of the following statements are correct? Note that some of these questions require you to have read relevant sections of Core Unit 13. [FOUR correct answers] Select one or more: a. The consumption function implies that if GDP is zero, consumption is zero b. b is known as the average propensity to consume c. If there is an increase in consumers who engage in "consumption smoothing", this will cause an increase in a and a decrease in b d. a is known as the marginal propensity to consume e. b is known as the marginal propensity to consume f. a is the level of consumption when Y is zero g. If consumption-smoothing consumers become more optimistic about the future, a will increase. h. If there are more credit-constrained consumers in the economy, this will cause the marginal propensity to consume, to fall
Suppose a closed economy has an aggregate consumption function given by C = 100 + 0.75Yd and generates $3000 output and income in equilibrium. Suppose also that the government spends 300 and imposes a lump-sum tax of 50. What is the level of intended investment? (round your answer to the nearest whole value)
Suppose an economy is depicted by the expenditure function provided below: C + G + I + X = $200 + 0.80×Y + $350 + $225 + $125 All figures are in billions of dollars. Assume there are no taxes in this nation so disposable income Yd = Y. The economy reaches an equilibrium at $enter your response here billion. (Enter your answer as a whole number)
Suppose the consumption function is given by C(Y)=60+0.8(Y-T) where Y represents output and T stands for net taxes. Suppose further that the level of investment, I, is 400, the level of government expenditure, G, is 300, and net taxes, T, are 200. What is the equilibrium level of output in this economy? a. 1720 b. 3000 c. 1590 d. 720
