Q1: There are two equations for macroeconomic equilibrium in an economy. State them. Show (mathematically) that Savings equals Investment when expenditure equals income. What type of economy would you have when exports equal imports? What happens to the savings-investment relationship if exports are not equal to imports? [This can be greater than or less than]. [Hint: See video lecture on Open Economy Macroeconomics]. Note: Ensure to write out full meanings when you use abbreviations or short forms. This is key to getting full marks.

The outbreak of COVID-19 adversely attacks most economies. Some economists e/2 argue that the impacts on the macroeconomy mainly come from (i) the reduction in consumption and investment appetite, while others believe that the impacts mainly come from (ii) the immediate destruction of the supply-chain and production. Suppose two quarters since the outbreak of the COVID-19, changes in selected macroeconomic data of Country X can be summarized as below: Last year This year Annualized economic growth rate 4% -6% Unemployment rate 5% 8% Inflation rate 2% 5% Using an AD-AS model, explain whether argument (i) or (ii) above fits better to а. the case of Country X. b. Given your answer in (a), briefly discuss one plausible short-run dilemma facing the central bank of Country X.
Consider the following model. Expenditure is given by: E = C +1 + G. The consumption function is specified as: C = c0 +cY. We assume a closed macroeconomics system so that: Y=E. If the model parameters are configured such that I= 500, G=2000, c0=1000 and c=0.8, what will the level of consumption expenditure, C, be equal to? a. 4,375 b. 15,000 c. 14,000 Cd. 14,500
Suppose that a new free trade agreement allows the economy to import cheaper goods from overseas, thereby decreasing the general price level. Adjust the following graph by either shifting the consumption function curve or the initial point on the consumption function curve (A) to illustrate the impact of a fall in the price level.

Assuming that there is no government spending or trade, an economy’s GDP is the sum of domestic consumption C and investment I, i.e. Y = C+ I Assume that I is unaffected by GDP Assume the consumption function is C = c0 + c1Y In any equilibrium aggregate demand, AD must be equal to Y, GDP. Given this model, which FIVE of the following statements are correct? Select one or more: A. If the economy above is a demand-driven economy, then the equilibrium solution for Y is given by Y = m(c0 + I), where m = 1/(1 - c1) is the multiplier. B. if c1 = 0.8 the multiplier is equal to 1/0.8= 1.25 C. if c1 = 0.75 the multiplier is equal to 4 D. assume c0 =100, I=50, c1=0.6. The equilibrium value of Y in a demand-driven economy is 300. E. Assume that Y is initially 400, I is initially 100, and the multiplier is 2.5. I increases by 10%. The multiplier implies that in equilibrium Y will increase by 25%. F. The higher is c1 the larger is the multiplier G. If consumers…

We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.
