Our closed economy has a production function Y = A•F(K,LxE), where Y, K, L, E & A all have their usual meanings as per our lectures & course textbook. Also, this production function exhibits all the usual mathematical/economic properties we usually assume: positive marginal products, diminishing marginal products, complementarity between K & (LxE), and constant returns to scale. The aggregate consumption function depends negatively on the real interest rate, the government budget is balanced initially & the economy is in both a long-run equilibrium and steady state initially. The population growth rate is 2% per year, capital depreciates at a rate of 3% per year, the saving rate is 25% and technology is constant. Suppose the level of labour effectiveness (E) suddenly permanently rises by 10%. a) Use the long-run classical model to determine the qualitative impact of this shock on the long-run equilibrium levels of real output, consumption, investment, real interest…

Consider the following​ one-period model. Consumer Utility function over consumption​ (C) and leisure​ (L) ​ U(C,L)= C^(1/2)L^(1/2) = Total​ hours: H​ = 40 Labour​ hours: ​= H​ – L ​Non-labour income:​ π ​Lump-sum tax: T Hourly​ wage: w Firm Production​ function: Y​ = ​zF(​) ​= z Total factor​ productivitiy: z​ = 2 Government Government spending​ (exogenous): G​ = 20 Suppose that the total factor​ productivity, z, increases to 5. What is the substitution effect of this wage change on labour ​supply(​)? A. ​+8.51 B. ​-5.51 C. ​-8.51 D. ​+5.51 E. None of the above

(1)The following macroeconomic model describes the economy of Sunderland. 1. Y= C +I + G + NX 2. C = 220 + 0.63 Y 3. 1 = 1000- 2000R 4. G = Go 5. NX = 525-0.10Y-50OR 6. M (0.1583Y-1000R)P (a)ls it a fair characterization to refer to equation #2 as a "simple" consumption function? Explain. (b)Derive the expression for equilibrium real output, Y, for this economy. Note: In your final expression for Y, restrict coefficient values to three decimal points. (c) Suppose government spending is 1200 , money supply by the Central Bank is 900 and the price level is 1, find the value of GDP (Y) and equilibrium interest rate (R) for Sunderland. Income Identity Consumption function Investment function Government Expenditure Net export function Money market equilibrium (2)The questions in this section are related to the macroeconomic model of Sunderland. (a)The expression you are asked to derive in question #1b can be considered an aggregate demand curve. Do you agree? Explain your answer. (b)Sketch…

Consider the following 2-period model U(C1,C2) = min{3C1,4C2} C1 + S = Y1 – T1 C2 = Y2 – T2 + (1+r)S Where C1 : first period consumption C2 : second period consumption S : first period saving Y1 = 20 : first period income T1 = 5 : first period lump-sum tax Y2 = 50 : second period income T2 = 10 : second period lump-sum tax r = 0.05 : real interest rate Find the optimal saving, S*

Hello, I'm trying to figure out how this person got this answer. I get stuck at the line after the fourth equal sign. Could you please explain in detail how this was simplified? Thank you.

do fast.

Typed plz and asap thanks
