- In the Keynesian macroeconomic model, the equation for the savings function is given as: S = -420 + 1/4Y. Based on this information, which of the following statements is correct? (1) The marginal propensity to consume is 1/4;(2) The marginal propensity to save is -420; (3) At an income level of R1 000, the value of savings is 250;(4) At an income level of R1 000, the level of savings is -170.In the Keynesian-cross analysis, if the consumption function is given by C=100+0.6(Y-T),and planned investment is 100,G is 100, and T is 100,then the equilibrium Y is: Select one: a. 400 b. 350 c. 750 d. 600If the Keynesian consumption function is C = 100 +0.75Y4 and there is no investment then, when disposable income is 500, what is the average propensity to consume? Round your answer to 2 decimal places e.g. 2.22
- look at the keynesian consumption function:c=c0+(mpc)(yd).which part of it relates to autonomous consumption?which part of it relates to included consumption?define autonomous consumption and induced consumptionState the main properties of keynesian consumption function i need three properties.According to Keynes's Consumption function, a) Consumption spending is a function of disposable (after-tax) income (Yd). b) There cannot be any consumption without disposable income. c) Total consumption spending is composed of autonomous consumption, independent of income (Ca), and induced consumption, determined by disposable income. d) The induced consumption component is equal to a constant proportion of disposable income. e) The induced consumption is equal to the marginal propensity to consume times disposable income f) The consumption function Is modified in the Lecture Notes to a simplified version where consumption is a function of real income. g) Autonomous consumption cannot be changed by other factors.
- Consider the Keynesian consumption function Yt =B₁ + B₂x2+ + Et ( where y, is per capita consumption, and x2+ is per capita income. The coefficient ₂ is interpreted causally as the marginal propensity to consume, and we expect 0 < ₂ < 1. At the same time, X2t = Yt + Z2t where Z2, denotes per capita investment. Assume for now that investment is exogenous and Cov(Et, 22t) = E[EtZ2+] = 0 Darixe, the: show steps reduced form X2t Yt = = B₁ 1- B₂ B₁ 1-₂ + + 1 1-₂ B₂ 1-₂ -Z2t + -Z2t + ( 1 1- B₂ 1 1-₂ -Et -Etthese bottom two are solved I am just struggling with how to graph the consumption function and the breakeven condition for this problem and to Point out the income and consumption values relevant for these problems: 3. The marginal propensity to consume (MPC) is 0.75, which means that households spend 75% of each additional dollar of income. The starvation-level consumption is 6, which means that households will consume at least 6 dollars, regardless of their income. Therefore, the amount that households will save can be found by subtracting their minimum consumption level from their gross income, multiplying the difference by the MPC, and subtracting the lump-sum tax: Savings = (1 - MPC) * (Gross Income - Starvation-level Consumption) - Lump-sum Tax Savings = (1 - 0.75) * (40 - 6) - 10 Savings = 0.25 * 34 - 10 Savings = 1.5 Therefore, households will save $1.5. 3. a) How should the lump-sum income tax change to allow households to save 3? To allow households to save…please kindly assist with the following QnA Induced consumption is: (a) the part of consumption which is independent of the level of income.(b) the minimum level of consumption that is financed from sources other than income.(c) The maximum level of consumption that is financed from sources other than income.(d) shown by the slope of the consumption function.In the Keynesian model, an introduction of a proportional tax will: (a) increase the slope of the consumption function.(b) reduce the multiplier.(c) increase the equilibrium level of income.(d) increase the multiplier.A decrease in the price level will: (a) shift the AS curve to the left.(b) shift the AD curve to the left.(c) shift the AS curve to the right.(d) leave both the AD curve and the AS curve unchanged. During an economic expansion, real GDP ____ and unemployment ____. (a) increases, increases (b) increases, decreases (c) decreases, increases(d)…
- Which of the following statements about the Keynesian framework are accurate? a)Keynes posited a linear Consumption function C=Ca + mpcYd, where C is total desired consumption spending, Ca is consumption spending independent of income and Yd is disposable income and mpc is marginal propensity to consume b) In the C=Ca +mpcYd the Ca is the vertical axis intercept parameter, and mpc is the slope parameter. c) Keynes also posited that Investment spending was a function of expectations and the interest rate. d) In the Keynesian investment function the firm's estimated profitability of potential investment projects were determined by expectations of future sales and costs. e) Businesses would invest in those projects whose estimated profitability was greater than the market rate of interest. f) If the firms don't have the cash, they will borrow funds and earn the difference between the rate of return on the project and the lower market rate of interest. If they have more cash than needed…Knowing that: The formula for economic impact is I(r)=(A)/1-r ---(i) The formula for impact change is ∆I= I'(r)*∆r ---(ii) The formula for percentage change in spending is g(r)=(r)/1-r ---(iii)In the Keynesian cross model, assume that the consumption function is given by C = 20 + 0.8(Y- T). Planned investment is 200; government purchases and taxes are both 400. There is no foreign trade. An economist has claimed that the full employment level of output is 2,400. How much should the government expenditure or taxes rise or fall to achieve full employment?
