What is the effect of an increase in iše in investment spending on the overall priceX level in the income-expenditure model? There is no effect because prices are not changing by assumption A Prices will increase, because increased investment spending B leads to higher GDP levels and higher prices. Prices will increase, as an increase in investment C spending will lead to higher interest rates and therefore higher prices.

- We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.In our construction of the savings and investment model, weconsidered government spending to be immediate spending. In otherwords, there was no “investment” component to government spending.Let’s change up that assumption. Suppose government spending comesin two types: investment spending (new airports, for example) aswell as government consumption (snow plowing, for example). Callthe first GI and the second GCE.Assume that in 2015, the following prevails in theRepublic of Nurd:Y = $200 G = $0C = $160 T = $0S = $40I (planned) = $30Assume that households consume 80 percent of their income, they save 20 percent of their income, MPC = 0.8,and MPS = 0.2. That is, C = 0.8Yd and S = 0.2Yd.a. Is the economy of Nurd in equilibrium? What is Nurd’sequilibrium level of income? What is likely to happen inthe coming months if the government takes no action?b. If $200 is the “full-employment” level of Y, what fiscal policy might the government follow if its goal is fullemployment?c. If the full-employment level of Y is $250, what fiscalpolicy might the government follow?d. Suppose Y = $200, C = $160, S = $40, and I = $40. IsNurd’s economy in equilibrium?e. Starting with the situation in part d, suppose the government starts spending $30 each year with no taxationand continues to spend $30 every period. If I remains
- Suppose that for a particular economy, for some time period, consumption was given by theconsumption function C = 300 + 0.9YD, investment was equal to 200, government expenditure wasequal to 100, net taxes were fixed at 100, exports were equal to 200, and imports were given by theimports function Z = 10 + 0.1YD. Note that YD represents disposable income. a.Suppose households earn $150 more in their disposable income. How much more would theyconsume in total? How much go to domestic goods and how much go to imported goods? Howmuch would they end up saving? b.What is the level of equilibrium income? What about the level of consumption and import? c.What are the values of the government spending multiplier, tax multiplier and balanced-budgetmultiplier? d.Suppose the investment level suddenly declined by 20. How should the government stabilize theeconomy? Please provide all options in detailCourse: Macroeconomic - IS-LM Model Prove mathematically the following: Given an increase in the proportional tax on income(t), what happens to the level of output and to the tax?" . Hint: for demostration, use the IS general function for a closed economy Y = C + I + G, where C = a + c*YD and YD = Y + TR - Y*t (where t = proportional income tax) and realize changes i.e., from "t1" to "t2"A country’s GDP is defined by the following equation: GDP = Consumer Spending + Investmentspending. The economy of this country is closed and there’s no government. Investment spendingis defined by the following equation: Investment Spending = Investment (planned) + Investment(unplanned). Investment (planned) is fixed at 350. Consumer spending is defined by thefollowing equation: Consumer spending = 200 + 0.55 (GDP). And for this country, PlannedExpenditure = Consumer Spending + Investment Planned. Based on this information, attempt thefollowing questions:a. “Investment (unplanned) will be negative if GDP is 900” – showing work, test theauthenticity of this statement. b. How do you think GDP (and production) will change if the income of this country is 1500?Explain by deriving Investment (unplanned) for an income of 1500. c. Derive the GDP for which Planned Expenditure = GDP. d. Supposed Investment (planned) was increased to 450. How will income-expenditureequilibrium change. e. Relate…
- 30. Given this model, what would be the change in equilibrium level of income were G to increase to 250? 31. Given this model, what would be the new equi8librium level of income were Investment spending to decline by 50?Suppose we have the following consumption function in an economy C = 2000 + 0.9YD. Howmuch government spending has to be increased in order to have an increase in equilibriumoutput equal to 1000? a. 100.b. 200.c. 250.d. 1000.e. none of these.f. do not have adequate information.Consider an economy called Xanadu for which desired aggregate consumptiondepends on income, Y. and the real interest rate, r, according toCd =100+0.7Y - 200r.Xanadu's GDP is Y = 1000 and government spending on goods and services is G=180. Xanadu's desired future capital stock is given byK* = 140 - 100ucwhere luCdenotes the user-cost of capital. The price of capital is PK =2, thephysical depreciation rate is d =0.1 and the existing capital stock is K0= 50. Trapital stock between any period t and the following period t+1 evolves accordng toKt+1 = It+(1-d)Kt where It the level of investment.
