Equilibrium in the goods market requires that Aggregate Output equals Aggregate Expenditures. Given that Consumption = Disposable Income minus Private Savings, mathematically prove that equilibrium in the goods market requires Investment (I) to equal national savings (S) -- hence the IS curve.

- The consumption and saving functions in the Keynesian model Suppose we observe that a person's disposable income (DI) is 50,000 in 2019 and 63,000 in 2020. Suppose we observe that this person's consumption (C) is 47,000 in 2019 and 58,700 in 2020. Assume that this person's consumption obeys the Keynesian consumption function, so that C = A + MPC*DI. Finally, assume that A and MPC are unchanged between 2019 and 2020. (a) Calculate the values of A and MPC for this consumer, and graph the consumption function. (Hint: subtract the C function in 2019 from the C function of 2020). (b) In general, saving is given by the formula S = DI - C. Calculate this person's saving in 2019 and 2020. Assuming that this person's wealth (net worth) on January 1, 2019 was 80,000, what is their wealth on January 1, 2020? on January 1, 2021? (c) In general, if consumption is given by the function C = A + MPC*DI, then saving will obey the saving function S = -A + (1 - MPC)*DI. Plot the saving function…Assume that total expenditure E comprises the sum of government consumption, G, household consumption, C, and investment, I. Assume a closed macroeconomic system, so that income equals expenditure Y=E. If we define household saving, SH, as SH=Y-T-C, where the cunsumption function is a fixed proportion of disposable income, C=c(Y-T), which of the following will be true? a. Higher government spending alongside unchanged taxation will lead to higher investment and higher household saving b. Higher government spending alongside unchanged taxation will have no effect on household saving or investment c. Higher government spending alongside unchanged taxation will lead to higher household saving d. Higher government spending alongside unchanged taxation will lead to lower household savingThe following are exogenous (not directly affected by income): G = 9 I = 14 X = M = 0 The consumption function is: C = k + cY, where k = 8, c = 0.6 What is the equilibrium level of GDP? State to ONE decimal place What is the multiplier for this economy? The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 What is the equilibrium level of GDP? What is the multiplier? Same information as in the previous question: The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 Imagine the maximum potential output or real GDP of this economy is 100. Assume that is the same as saying we reach the edge of the PPF at 100. Now assume we want to get that economy from the current level of GDP to its maximum potential of 100. We can do this in two ways - either increase government spending (G) or reduce taxes, (we…
- National income accounting (GDP calculate) is an essential part of macroeconomics. Analyse the following hypothetical economy and answer the questions that follow: G = 400, I = 70, X = 300, M =100, autonomous consumption = 100, MPC = 0.6, taxes=50 Calculate the level of national income in this economy What percentage of disposable income do people save? Calculate the level of savings Show that in this economy, injections are indeed equal to withdrawals Calculate the multiplier? Using the multiplier in v above, what would be the new level of national income if government spending rose to 500?In the country of Borealis, the minimum amount of consumption spending that will occur is $300 - that is, no matter what level of income households have, the aggregate amount of consumption spending in the economy will be at least $300. In addition, for every extra dollar of national income, consumption spending will increase by $0.75.In a closed economy, subsistence consumption is 10 billions, households spend 60% of their net disposable income on leisure consumption, investment is constant at 40 billions, taxes are 20 billions, government spending is 20 billions and the gross domestic product is 145 billions. Assume that suppliers always respond to variations in demand, that it takes them 1 month to adjust to new demand levels and that they make adjustments once per month (if any). One day, the government increases its spending to 30 billions. After 2 months (at the end of the 2nd month), by how much has the gross domestic product increased? Select one: a. 16 b. 25. c. 32 d. 50
- Please write down whether the following statements are true or false, and explain your answer very briefly A)If actual investment is greater than planned investment, inventories increase more than planned. B)The marginal propensity to consume is the change in consumption expenditure divided by the percentage change in income. C)Gross domestic product (GDP) is the value of all goods and services produced in an economy over a particular time period. D)Monetary policy refers to taxation and spending policies implemented by government. E)In a simple Keynesian model (with lump-sum taxes and a MPC of 0.8), a tax cut of 20 billion TL will have less of an impact on GDP than an increase in government spending of 10 billion TL. D)When you take 1000 TL from your savings account and deposit it in your checking account, M2 decreases. F)An open market purchase of government securities (such as Treasury Bills) by the Central Bank will decrease the money supply and raise the interest rate.…Question 17 In early 2000, China was the fastest emerging economy in Asia. However, in recent years, China has indicated deteriorating growth beginning of 2020. Suppose consumption function for China is C = 250 +0.6(Y-T) and taxes are T = 15+0.05Y, meanwhile investment is 250, government outlays are 400, and net - export is 300. a) What is the multiplier value for China? b) Suppose China's investment has dropped to 200, government outlays received deduction from the budget by 25% and other components are ceteris paribus. Calculate the national equilibrium new national income equilibrium. c) From the changes that happened in (b) China has reaccelerated export and import activities. This sector has contributed another $100 for net-export, meanwhile other components are ceteris paribus. Calculate national income equilibrium using multiplier approaches.The private consumption of Macroland is given by C=500+0.75Y and the private investment function is given by I=400−1000r, where r is the interest rate and Y is the GDP. The planned aggregate expenditure can therefore be written as PE=C+I=900+0.75Y−1000r. The equilibrium in the goods and services market happens when the planned expenditure is equal to the actual expenditure, or PE=Y Find the equilibrium GDP by solving the system of equations PE=900+0.75Y-1000r PE= Y for Y and PE. Note your solutions will depend on r! 1. Plot your solution for Y in a diagram measuring Y on the horizontal axis and r on the vertical axis. This curve is called the IS curve.
- The following are exogenous (not directly affected by income): G = 11 I = 4 X = M = 0 The consumption function is: C = k + cY, where k = 3, c = 0.8 What is the equilibrium level of GDP? What is the multiplier?You are given the following data concerning Kadwan, a country located in the mountains. • Consumption function: C = 125 +0.50Y • Investment function: I = 125 • Aggregate expenditure function: AE =C+I • Equilibrium: AE = Y Describe the graph of the consumption function and the aggregate expenditure function and then identify the equilibrium level of income. The consumption function has an intercept of and a slope equal to MPC = =. The AE line is found by adding I to C. AE is achieved at Y = C with a slope equal to the MPC and an intercept of Equilibrium is steeper than parallel to flatter thanWhich of the following best describes the catch-up effect? Question 14 options: It is easier for a country to grow fast and "catch up" with richer countries if it starts out relatively poor. Saving will always "catch up" with investment spending. If investment spending is low, increased saving will help investment to "catch up." Rich countries aid relatively poor countries so as to help them "catch up."
