- 3. Determinants of aggregate demand The following graph shows an increase in aggregate demand (AD) in a hypothetical country. Specifically, aggregate demand shifts to the right from AD₁ to AD2, causing the quantity of output demanded to rise at all price levels. For example, at a price level of 140, output is now $400 billion, where previously it was $300 billion. 170 PRICE LEVEL 160 150 140 120 110 100 90 0 +--+ AD2 AD1 600 100 200 300 400 500 OUTPUT (Billions of dollars) 700 800Suppose the US economy enters a recession. During the recession, inflation falls and interest rates rise. What kind of change ("shock") to demand and or production is likely cause of the recession? Answer in one short paragraph.

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.
- In this problem you will work with the IS-MP model to calculate a macroeconomic equilibrium using algebra. The steps are: 1) find the IS equation 2) find the MP equation 3) combine them by substituting the r value from the MP equation into the IS equation Assume C = 1 + 0.75Y - 0.5T - 25r, I = 19 - 75r, G = 12, T = 14, the average FFR = 0.05, expected inflation is 3%, the risk premium is 4%, and potential output is 80. What is the output gap in the macroeconomic equilibrium?Considering a three sector economy, i.e., Y = C + I + G, derive the expression for output (Y) and aggregate demand equitionsAD AD AD, Real GDP Refer to the above diagram. An expansionary fiscal policy can best be represented by a: Multiple Choice shift in the aggregate demand curve from AD2 to AD1. shift in the aggregate demand curve from AD3 to AD2. Prex Price Level
- Consider the following model of house prices: lhprice=β0+β1bdrms+β2llotsize+β3lsqrft+u The variables are defined as: lhprice = the natural log of the house price bedrms = the number of bedrooms llotsize = the natural log of the land or lot size lsqrft = the natural log of the floor space of the house in square feet. You may assume the Gauss Markov Assumptions hold. Which of the following will make our inference on the partial effect of the number of bedrooms on the house price less precise? a) A smaller variance of any unobserved factors captured in the error term, u. b) A larger sample size. c) More variation in the number of bedrooms across the observations in the sample. d) None of the possible answers describe something that would make our inference less precise. e) A higher correlation between the number of bedrooms and the floor space of the house.A. Based on the graph would you say marginal utility is increasing or decreasing B.
