- Inventories typically increase starting at the beginningof recessions, and begin to decline near the end ofrecessions. What does this say about the relationshipbetween planned spending and aggregate output overthe business cycle?Given the following consumption function, C = 400 + 0.75YD,where C= consumption expenditure, YD = disposable income, Investment= $1200, Government spending = $1600,Exports = $500, Imports = $600, Taxes = $1200 and Potential GDP = $9000Choose corrcct optiona) Aactual output is less than potential outputb) actual output is zeroc) actual output is equal to potential outputd) actual output is higher than potential output| Assume in country Y, the average marginal propensity to save is 0.2. When the aggregate income is zero, consum- ers spend 50 to consume. Derive the saving function and consumption function for this country. What happens to consumption when the propensity to save decreases to 0.1? Explain your answer and show this on the graph.

- 11. For an economy, if the marginal propensity to consume is 0.75, how much will the national income increase for an initial investment increase of CNY100 million yuan?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?Suppose MPC equals 0.9, government taxes 30% of all incomes, and the marginal propensity to import equals 0.07. The economy's real GDP is currently $5,454 billion while its potential real GDP is $6,000 billion. Glven a horizontal SRAS curve, what change in government spending on goods and services would bring the economy to full employment real GDP? When doing the calculations, round the value for the multiplier to 2 decimal places, and round your final value for the change in G to the nearest billion.
