- 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.Consider a closed economy to which the Keynesian-cross analysis applies. Consumption is given by the equation C = 200 + 2/3(Y – T). Planned investment is 300, as are government spending and taxes. What happens to unplanned inventory investment? Should equilibrium Y be higher or lower than 1,500?The Wilson family has a disposable income of $70,000 annually. Currently, the Wilson family spends 80% of new disposable income on consumption. Assume that their marginal propensity to consume is 0.8 and that their autonomous consumption spending is equal to $10,000. What is the amount of the Wilson family's annual consumer spending?
- 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…Which one of the following statements relating to marginal propensity to consume is INCORRECT? (a) Marginal propensity to consume for a given consumption function is usually less than 1; (b) If the people in a country save 30c out of every rand they earn, the marginal propensity to consume in this country is said to be 0.7; (c) If the marginal propensity to consume is given as 0.622, then the value of the simple multiplier will be 2.5; (d) The larger the value of the marginal propensity to consume, the steeper the consumption function will be.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.…
