1. An economy is described by the following equations: Expenditure Sector: Money Sector: S = - 200 + (1/5)YD Ms = 400 TA = (1/8)Y - 40 Md = (1/4)Y + 100 - 5i TR = 60 I = 300 – 10i G = 70 NX = 150 - (1/5)Y Here S is saving; TA is taxes; TR is transfers; I is investment; G is government spending; NX is net exports; Ms is money supply; and Md is money demand. a) (30p) Find the IS and LM equations for this economy. Draw those equations in an IS-LM framework. b) (20p) Find the equilibrium level of output and interest rates. Calculate also the equilibrium values of investment (I), net exports (NX), and money demand (md).

As the marginal propensity to consume (mpc) increases, the multiplier remains the same. increases. decreases. as the marginal propensity to save (mps) increases, the multiplier decreases. increases. remains the same. if the marginal propensity to consume is 0.30, what is the multiplier, assuming there are no taxes or imports? round to the tenths place. given the multiplier that you calculated, by how much will gross domestic product (gdp) increase when there is a $1,000 increase in government spending? $

Jennifer purchased a house in a brand new development in the outskirts of town. when her house was built, the nearest fire department was nearly 20 miles away. as her neighborhood developed, the density of the community called for a new fire department 1.5 miles away. what effect will the new fire station have on her homeowners insurance premium? a. a new fire department will be more demanding on local taxes. her annual premium will go up. b. the location of a fire department has no bearing on the value of her house. her annual premium will stay the same. c. the new fire department will reduce the risk of financial loss in her home. her annual premium should decrease. d. with a fire department so close (less than 5 miles), financial risk on jennifer’s home practically disappears. she will not need to pay insurance anymore.
