If the MPC rises to 0.8 and also the sensitivity of real money demand to changes in the income rises well, use the IS-LM model to illustrate the impact of an expansionary fiscal policy. Label the initial point prior to the fiscal policy as A and the new point following the expansionary policy as B.

Match the following terms ( terms are labeled 1-10 )to the correct definition(definitions are labeled a through J) aggregate consumption function, multiplier, planned aggregate expenditure (PAE), income-expenditure equlibrium GDP, marginal propensity to consume (MPC), consumption function, unplanned inventory investment, actual investment spending,inventory, autonomous spending A) The amount by which consumption rises when disposable income rise by one dollar marginal propensity to consume (MPC) B) The level of output (real GDP) at which output (real GDP) equals planned aggregate expenditure. income-expenditure equlibrium GDP C) The ratio of total change in real GDP caused by an autonomous change in aggregate spending. multiplier D) Total planned spending on final goods and services in the economy. aggregate consumption function E) The equation showing how individual household's consumer spending varies with its current disposable income. consumption function F) Consumption…

Consider the following macroeconomy. All amounts are in millions (m.) of $: C = 750 + 0.8 YD                                    I = 1200                                    G = 150                                    T = 250 Calculate eqm Y and prove that I=sum of S at this equilibrium. What is meant by the “Paradox of Thrift” (POT)? Go back to the original eqm of part a. Now prove using multiplier analysis that the POT holds in this economy by assuming that the change in co is -$50 m. As part of your answer, explain “intuitively” why this paradox exists.  Show what happens in the Z-Y space graph.

Assume a model economy with the following parameters: C=300+0.25 Yd I=250+0.5Y-2500i G=350 T=300 (M/P)d= 4Y-16,000i (M/P)s= 880   Derive the IS and LM relations and solve for equilibrium real output and equilibrium interest rate.

2.1 According to the permanent income hypothesis, how will a representative consumer's bor- rowing and consumption respond to: 1. An anticipated temporary decrease in income at t = 2. 2. An anticipated permanent decrease in income (at time periods t = 1 and t = 2) when it occurs. 3. Are the answers different if the changes in income are unanticipated, i.e. if they come as a surprise to the consumer? Comment on the size of the marginal propensity to consume.

Suppose the economy of Ghana in 2020 was characterized by C = ¢400m + 0.75(Y-T); I = ¢400m - 20r; G = ¢200m; T = ¢200m; Ms = ¢250m/P; Md = 0.25Y - 10r a. Derive the IS and LM curve equations. Give a brief explanation as to why they are positively or negatively sloped. b. Calculate equilibrium output and interest rates (in this case assume P=1). Econ313 2020/2021 PROBLEM SET 2 Page 1 of 2 c. Suppose the government of Ghana in the second half of 2020 spent an additional ¢50m to mitigate the impact of the COVID pandemic on households and businesses and government tax revenue declined by 10% as a result of the lockdown in Ghana what will be the new equilibrium output? d. Will the policy in (c) above have an impact on interest rate? Briefly explain. e. What is the amount of the fiscal deficit incurred as a result of the government fiscal policies as pursued in (c) above?
