Economics Suppose that the effects of COVID-19 on the economy can be thought of as a permanent negative productivity shock, i.e., a permanent decrease of the production owing to lower total factor productivity. What does the model predict will happen to the following variables: (1) real interest rate, (2) real output), (3) real consumption, (4) real investment, (5) labor input? For each variable explain why COVID-19 would have the predicted effect.

Consider the short-term model characterized by the following AS and AD curves: Ý, = à – bm(x, – ñ) (AD] and A; = x; + vỶ, + õ, (AS). The economy is in steady state at time t = -1 (that is, a-1 = ñ, ō-1 = 0, and ā = 0). It is hit by a one-time inflation shock öy = .025 at time i = 0. For now, expectations are adaptive: 7 = ,-1. You'll use the answer to this question in several follow-up questions. To keep track of your results, you should use a spreadsheet application. If you don't already have one, you can use this hyperlinked template e (it's a Google Sheet). Calculate zo assuming b = 0.5, m = 2, ñ = 0.03, and ū = 1. Enter your answer as a percentage and round to the nearest hundredth.

What must be true of the model parameters and variables in the long-run equilibrium, i.e. in the steady state? Analyse the effects of an oil supply shock that causes a temporary increase in inflation, using the three-equation model. Assume that the shock lasts for one-period and then assumes the value 2%. Describe the mechanisms that bring the economy back to long-run equilibrium. What happens to aggregate demand? Consider an economy that starts out in steady state when the central bank decides to make the inflation target more ambitious. Analyse the effects of a decrease in the inflation target from ? to .

Do you remember the Harrod-Domar model? Derive it and apply it to a numerical case where d=4%, s=35%, and gY=8% last year. If s is expected to rise to 45% next year, what will happen to gY?

Use r = 5, 10, 15 and Use the IS-LM model to predict the short-run effects of each of the following shocks on income. A wave of credit card fraud increases the frequency by which people make transactions in cash. A best-seller novel titled “The Financial Diet” convinces the public to increase the percentage of their income devoted to savings.
a) Which of the following would a classical macroeconomist disagree with? The interest rate is the price of time or productivity of capital Nominals effect nominals Recessions are caused by an over production of all economic goods Prices should be as flexible as possible Effective demand comes from prior supply b) Which of the following is true? The expected costs and returns for holding money are important for estimating the demand of real cash balances The difference between nominal GNP and real GNP is that nominal GNP has been adjusted by a price deflator to account for changes in the value of money (inflation) People in Group 1 receive the inflation tax on their cash-balances Interest is the price of money The real money supply is equal to the nominal money supply divided by the real money supply
I have to analyze, using the IS-LM model, the macroeconomiceffects of an increase in savings in the short term and its implications for long-term growth. Specifically, I have to suppose that households (consumers) lose confidence and start saving more for any level of disposable income. The question is: Using the IS-LM model, show the effect of an increase in saving on production,investment and consumption, assuming that the Central Bank modifies the money supply when income changes, so that the LM curve is flat.
