- Suppose that for every increase in the interest rate of one percentage point, the level of investment spending declines by $0.5 billion. Based on the changes made to the money market in the previous scenario, the new interest rate causes the level of investment spending to by Taking the multiplier effect into account, the change in investment spending will cause the quantity of output demanded to known as the by at every price level. The impact of an increase in government purchases on the interest rate and the level of investment spending is effect. Use the purple line (diamond symbol) on the graph at the beginning of this problem to show the aggregate demand curve (AD3) after accounting for the impact of the increase in government purchases on the interest rate and the level of investment spending. Hint: Be sure your final aggregate demand curve (AD3) is parallel to AD₁ and AD₂. You can see the slopes of AD₁ and AD₂ by selecting them on the graph.5:45 PM A 5 P NO fill 1.5 42 K ECF515-D-1-2021-1.docx SESSION A: CHOOSE THE BEST ANSWER 1.

- The enormous budget deficits of 2009 through 2011 meant that the federal government was borrowing upwards of $1.5 trillion per year. If that borrowing had limited the ability of the private sector to get financial capital for its purposes, economists would call this crowding out. There was O significant evidence this was a problem because interest rates were very high. O little evidence this was a problem because interest rates were very low. O significant evidence this was a problem because interest rates were very low. O little evidence this was a problem because interest rates were very high.4.

- We found that for every $1 increase in G there is a multiplied impact on output with, in the most 1 basic model, a multiplier of A study by economists at the New York Fed conducted 1- MPC during the COVID-19 recession found that "as of the end of June 2020, a relatively small share of stimulus payments-ljust] 29 percent-was used for consumption." What is the G multiplier based on that estimated MPC and the formula from the basic model?What will be the effect of “contractionary fiscal policy of abroad” on net export, saving and interest rate? Show your answer with the help of graph and also properly explainCOURSE: MACROECONOMICS - IS-LM and/or MUNDELL FLEMING MODELS Refer to 2 different models (and/or conditions) under which an increase in the amount of money circulating in the economy has a NULL impact on GDP. Then, refer to 2 different models (and/or conditions) under which an increase in the amount of money circulating in the economy has a MAXIMUM impact on GDP. EXPLAIN very briefly the mechanism by which each model generates that NULL or MAXIMUM impact on GDP. Hint: 2 conditions under increase of M (money) and how impact null (zero) and maximum on GDP. Example, considering both fiscal or monetary policies or liquidity trap model. Please graph and explain on detail both cases.
