- Suppose two countries have identical aggregate demandcurves and potential levels of output, and g is the samein both countries. Assume that in 2019, both countriesare hit with the same negative supply shock. Given thetable of values below for inflation in each country, whatcan you say, if anything, about the credibility of eachcountry’s central bank? Explain your answer.Country A Country B2018 3.0% 3.0%2019 3.8% 5.5%2020 3.5% 5.0%2021 3.2% 4.3%2022 3.0% 3.8%Suppose that changes in bank regulations expand theavailability of credit cards so that people can holdless cash.a. How does this event affect the demand formoney?b. If the Fed does not respond to this event, what willhappen to the price level?c. If the Fed wants to keep the price level stable,what should it do?2. Suppose country A has a central bank with full credibility, and country B has a central bank with no credibility. Assume that in 2020, both countries are hit with the same COVID-19 shock.If the both central banks announce an autonomous easing policy to reduce the unemployment rate, a) How does the credibility of each country’s central bank affect the speed of adjustment of the aggregate supply curve to policy announcements? b) How does this result affect output stability? (Use aggregate supply and demand diagrams to demonstrate)
- 2. Suppose country A has a central bank with full credibility, and country B has a central bank with no credibility.Using a graph of aggregate demand and supply EXPLAIN how the credibility of each country’s central bank affect economic outcomes, if both countries are hit with the samea) positive aggregate demand shock? b) negative temporary aggregate supply shock? EXPLAIN EVERTHING IN DETAIL PLEASEWhich monetary policy tool can the Federal Reserve use to conduct an expansionary monetarypolicy (please state at least one instrument)? Which monetary policy instrument can the Fed useto conduct a restrictive monetary policy? Assume the country is experiencing highunemployment and a recession, such as during 2001, 2008-2009, and 2020. What is the Fedlikely to do in this scenario? Discuss the effects of such policy on the economy. Can you givea specific example to what the Fed did during any of those recessions? This is not a writing, it is economic.Suppose that the Fed sets the interest rate and adjusts the money supply accordingly (i.e., horizontal LM curve) and the economy is in recession. (a) In this part, suppose also that private business investment spending depends only on sales expectations. What kind of policy mix would be able to increase output? Why? Explain. [Hint: Begin with showing the implications of assumptions first.] (b) In this part, suppose also that private business investment spending depends on both sales expectations and the rate of interest. How would your answer in part (a) change? What if the interest rate is already equal to zero (i.e., the zero lower bound). What kind of policy mix would be able to increase output? Why? Explain.

Explain why the aggregate short-run aggregate supply curve is upward sloping? b. What is the theory of liquidity preference? c. How does it help to explain the downward slope of the aggregate demand cure?d. Suppose that changes in the bank regulations expand the availability of credit cards so that people need to hold less cash.(i) How does that affect the demand for money? (ii) If the Central Bank does not respond to this event, what will happen to the price level?
