A8. An increase in the marginal rate of tax, with other things equal, should lead to a) a decrease in the size of the Keynesian multiplier b) an increase in the size of the Keynesian multiplier c) no change in the size of the Keynesian multiplier d) an indeterminate effect on the size of the Keynesian multiplier

A. Suppose you are given the following fixed-price Keynesian model: C=280 + 0.9Y. I-200 G=100 X3D200 M= 100 + 0.1Y. T= 100 a. Find the aggregate expenditure function. b. Find the equilibrium level of real GDP. C. What is the spending multiolier in this model? Tax multiplier? d. Show that leakages injections at equilibrium. e. If taxes increase by $100, what is the new equilibrium level of GDP? E. Show your answers to b) and e) graphically.

Consider a closed economy where investment is constant and the marginal propensity to consume is 0.8. In that economy, the government decides to increase its expenditures. Why is the associated Keynesian multiplier greater than 1? Select one: a. Because the production increase leads to a revenue increase which leads to a demand increase which leads to a consumption increase which leads to further increases in production, demand and consumption b. Because the demand increase leads to a consumption increase which leads to a GDP increase which leads to a supply increase which leads to further increases in consumption, revenue and supply c. Because the demand increase leads to a supply increase which leads to a revenue increase which leads to a consumption increase which leads to further increases in demand, supply and GDP d. Because the production increase leads to a demand increase which leads to a supply increase which leads to a revenue increase which leads to further increases in…

Consider a 4-sector Keynesian model like that discussed in class with the following characteristics: exogenous consumption=2000, exogenous taxation=100, government spending=1000, exports=400, planned investment=400. The marginal propensity to save=20%, the marginal tax rate=20% and the marginal propensity to import=40%. The potential output for this economy is 6000. Note that import demand depends on disposable income. a) At its short run equilibrium, this economy is experiencing __________ (a contractionary/an expansionary) gap of __________ (round to 2 decimal places) b) Following the outbreak of a pandemic in the above economy, exogenous consumption falls to 1000 and the marginal propensity to save increases to 40%. In order for this economy to experience a zero output gap, government spending must ____________ (increase/decrease) by ____________ . Assume all other quantities remain unchanged

Assume that the Marginal Propensity to Consume (MPC) is 0.8. If the multiplier effect is taken into account, the reduction in government expenditure by $ 200 million will shift the overall demand process to the correct order below. A) right, $1,000 million B) left, $ 200 million C) left, $160 million D) left, $1,000 million E) right, $ 160 million

If the Keynesian multiplier is defined as 1/ (1-c) where c is the proportion of income that is consumed, then when c increases, a. the multiplier decreasesb. income declines c. the multiplier increases d. investment increases

Consider a Keynesian model of the economy with the following equations; C = 300 + 0.7Yd = 500 TR ァミ250 = 300 = 400 X 150 M = 0,2Y The equilibrium level of income is O €1,500 €2,720 €2,650 O €1,325

a) Explain the principle of consumption smoothing. Illustrate this concept with a diagram. b) Explain how borrowing constraints can impede the process of consumption smoothing. If many households are affected by such constraints, explain how this may result in a “Keynesian" consumption function. c) In a closed economy Keynesian Cross framework show the link between the consumption function and the "multiplier". d) What assumptions are required to make the multiplier model relevant to the impact of fiscal and monetary policy?

If the intersection of AD and SRAS occurs at $21 trillion GDP but full employment GDP (LRAS) is at $22 trillion GDP, which of the following policy choices would help move the economy toward full employment? a) Lowering income taxes and payroll taxes for all employees. b) All of the choices would help increase AD and bring the economy closer to full employment. c) increasing the money supply to lower interest rates. d) Increases government spending on infrastructure. e) Sending out stimulus checks to everyone earning less than $100,000 per year.

true or false and why  The economy is at the Keynesian equilibrium. Assuming that taxes are zero, a decrease in the marginal propensity to consume decreases unplanned inventories in the short run.
