- 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 unchangedIf the consumer function has the form C = 100 + 0.8 (Y-T), where T is the level of lump-sum taxes, then in a simple Keynesian model, when government spending changes by 10 million, IS will shift by:Suppose we have the following information for the simple (fixed r, fixed P, fixed W) Keynesian model. C = 400 + 0.8 I = 310 G = 140 = 400 + 0.8 (Y - T) T = 200, where C is the consumption function, (Y - T) is disposable income, I is investment, G is government spending, and T is taxes.

C)Gross domestic product (GDP) is the value of all goods and services produced in an economy over a particular time period. D)Monetary policy refers to taxation and spending policies implemented by government. E)In a simple Keynesian model (with lump-sum taxes and a MPC of 0.8), a tax cut of 20 billion TL will have less of an impact on GDP than an increase in government spending of 10 billion TL. D)When you take 1000 TL from your savings account and deposit it in your checking account, M2 decreases. F)An open market purchase of government securities (such as Treasury Bills) by the Central Bank will decrease the money supply and raise the interest rate.…In the Keynesian cross, assume that the consumption function is given by C = 200 + 0.75 (Y − T). Planned investment is 100; government purchases and taxes are both 100. What level of government purchases is needed to achieve an income of 1,600?In the Keynesian cross model, assume that the consumption function is given by C = 100 + 0.75(Y - T). If government spending increases by AG = 100, what is the increase in output? How does your answer change when the spending increase is financed by an equal increase in taxes?
