8. The income-expenditure model Consider a small economy that is closed to trade, so its net exports are equal to zero. Suppose that the economy has the following consumption function, where C is consumption, Y is real GDP, I is investment, G is government purchases, and T stands for net taxes: c=15+0.75 x (Y-T) Suppose G = $90 billion, I $60 billion, and T - $20 billion. Given the consumption function and the fact that for a closed economy total expenditure can be calculated as Y=C+I+G, the equilibrium output level is equal to S billion. Suppose the government purchases are increased by $50 billion. The new equilibrium level of output will be equal to Based on the effect of the change in government purchases on equilibrium output, you can tell that this economy's spending multiplier is equal to

13. Assuming that an economy’s aggregate demand is given by its domestic consumption C and investment I, AD = C + I = c0 + c1Y + I. In the economy’s goods market equilibrium, this equals its output: AD = Y. Solving for Y this yields: Y = [1/(1 -c1 )] (c0+ I) Given this equation, which of the following statements is correct? 1. The multiplier is given by 1 – c1. 2. The boost in the economy’s output is the same, regardless of whether the aggregate demand shock comes from an increase in investment I or in autonomous consumption c0. 3. The larger the marginal propensity to consume (c1), the smaller the multiplier. 4. If c1 = 1/3, then a £1 million increase in investment would result in a £2 million increase in output. 14. In the US and the UK, loans are…

6) Suppose the Canadian economy is represented by the following: C=100+0.8Yd T-$50 I-20+0.1Y G-200 Yd-Y-T a) What is the equilibrium level of output? (Hint: first, drive the equation for C as a function of Y, then drive the equation for Z) b) What is the multiplier?
(a) Suppose in a simple Keynesian economy, planned consumption function is given by C=250+0.65(Y-T). Planned investment, government purchases, taxes are $100 million, $100 million and $150 million respectively. What is MPC, MPS and autonomous consumption Derive the saving function. What is the equilibrium level of income? Y= AD=C+I+G If government purchases increase to $150 million, what is the new equilibrium level of income? What level of government purchases is needed to achieve an income of $2000 million? From question e) you get the newly government purchase. Now find out the multiplier value What is the amount of shift in AD curve? [Use the multiplier value from e)] (b) In a self-regulating economy “X”, labor supply is 40 million but labor demand is 10 million. What will happen in goods and service market simultaneously? Explain this situation with relevant graph. Based on your findings in a) is it denoting long run equilibrium? If not, will the economy be able to restore…
A simple closed economy with government sector is given by the following equations: C = 10 + 0.75 Y I = 20 G = 40 where C is aggregate consumption, Y is national income, G is government expenditure on goods and services, and I is investment expenditure. Note that there are no taxes assumed in parts (a) to (c). (a) What is the equilibrium level of national income? Show all your workings. (b) What is the value of aggregate consumption and the value of aggregate savings at the equilibrium level of the national income? Show all your workings. (c) What would be the new level of national income if government expenditure increased by 10? Show all your workings and explain the mechanisms through which the economy reaches a new equilibrium. (d) If a tax rate of 1/3 of national income were introduced, what would be the new equilibrium level of national income in the economy outlined above. Show all your workings and explain the mechanisms through which the economy reaches the new equilibrium.
if investment spending at each level of output increases by $120 billion, what will equilibrium output and income be?
C is consumer expenditure T is tax revenue Y is aggregate output I is investment expenditure r is interest rate G is government expenditure L is money demand M is money supply Derive the relevant matrix inverse (do not use Cramer's rule) to solve for the equilibrium level of income in terms of government expenditure (G). At what level of public spending does the government balance its budget? (Hint: the endogenous variables are Y and r).

Suppose that we are in an economy with international trade, the government, domestic consumption, and investment. The government retains a tax rate of 10%. - Suppose that we observe this economy at two levels of national income (Y) ceteris paribus: (i) Y = 1,000 and (ii) Y = 1,800. The amounts for each of these desired expenditure categories at each of these levels of Y are given by: At Y = 1,000: + Consumption = 1,000 - Government Spending = 550 %3D Investment = 150 %3D Imports = 100 t Exports = 150 At Y = 1,800: 4 Consumption = 1,560 - Government Spending = 550 Investment = 270 e %3D Imports = 180 Exports = 150 Based upon this data, answer the following questions. We will keep referring to four categories - these are Consumption (C), Investment (1), Government Spending (G), and Net Exports (NX). « | 1. Plot both of the Desired Consumption and Desired Savings Functions, with Y on the x-axis and C & S on the y-axis. Label both functions' y-intercepts, and the x-intercept for the…
