Comparing ModelsWhat are the differences between our Keynesian Cross and the Macro Equilibrium (AS and AD) diagram? Which model has more to offer?
Is the way that NBER measures a recession fair and accurate? Please explain
Prompt We have been discussing major macroeconomic concepts like the ADAS Model and Fiscal Policy. This is an opportunity to apply that knowledge to a real-world scenario. Choose one of the following scenarios and identify whether it is an example of a recessionary economy or inflationary economy. Next, analyze possible Neoclassical solutions for it. Then, analyze possible Keynesian solutions for it. What would the impact on the economy be in the short-run? Long-run? Scenario 1: An increase in the unemployment rate to 7.4% has occurred. Inflation has increased causing a decline in consumer spending. Exports have declined by more than $4 billion. This has caused a decrease in GDP by 3.7%. Scenario 2: An increase in consumer and government spending has occurred. This has increased GDP by 4.4%. Currently, inflation rate has increased to 1.6%. Unemployment has remained at 5.5%. Scenario 3: An increase in the stock market by 26.5% has occurred. Companies are stockpiling the earnings…

Suppose that in Macroland the consumption and the investment have a negative relationship withthe real interest rate and positive relationship with Y. The Central Bank of the country targets acertain nominal interest rate and lets the money supply adjust in order to reach that interest rate.a. Draw a graph of the IS-LM model in this situation.b. Suppose that the Central Bank announces an increase of the interest rate in the future.Represent graphically the initial position of IS-LM curves. Then, show the IS-LM curves of thefuture, after the announced increase in the interest rate is implemented. (Assume that the ISis constant.).c. Suppose that agents today take into consideration the resulting income of the future whendeciding the amount of consumption and investment. Show what happens to the IS-LMcurves today after the announcement of the CB (tip: the CB is NOT increasing the nominalinterest rate today).d.
