The consumption and saving functions in the Keynesian modelSuppose we observe that a person's disposable income (DI) is 50,000 in 2019 and 63,000 in 2020. Suppose weobserve that this person's consumption (C) is 47,000 in 2019 and 58,700 in 2020. Assume that this person'sconsumption obeys the Keynesian consumption function, so that C = A + MPC*DI. Finally, assume that A and MPC areunchanged between 2019 and 2020.(a) Calculate the values of A and MPC for this consumer, and graph the consumption function. (Hint: subtract the Cfunction 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 thatthis 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 graphically for the consumer in this problem (using the values you found inpart (a)). What is this consumer's marginal propensity to save?(d) Calculate the level of disposable income such that saving is exactly zero for this person. If disposable income is lessthan this level, what happens to saving? Explain how a person can have negative saving, and give two examples of howa person can finance negative saving.(e) Suppose that this person earns 70,000 in 2021. What will their saving be in 2021?(f) Which of the following combinations of asset transactions could be consistent with the level of saving that youfound for this person in 2021?More than one answer can be correct-answer either "yes" or “no" for each of thefollowing combinations and explain your answer in terms of the increase in net worth implied by these transactions.F1: Buy 1000 worth of stocks, sell 4000 worth of jewelryF2: Buy a house worth 200,000; take out a 195,000 mortgage loanF3: Repay a 10,000 student loan; put 5000 in a bank accountF4: Repay a 7,000 personal loan, sell 2000 worth of stocks

Assume the following consumption schedule: C=20+0.9Y, where C is consumption and Y is disposable income. The MPC is:
If the consumption function is C = 80 + 0.6Y, then the marginal propensity to consume equals: 0.6. 0.4. 0.5. -0.4.
Suppose you know the following facts about consumer behavior of Amy in 2019. In a year, Amy spends $10000 on basic household items regardless of how much she is earning. For every dollar of disposable income earned, Amy spends 50% on extra purchases. Amy pays taxes in the amount of $1000, and receives no transfers. Use this information to: Derive Amy’s consumption function in nominal terms. Suppose the price level index in the economy for 2019 is estimated to be P = 2. Rewrite the consumption function in real terms.
Q.1.8 If the marginal propensity to consume increases: (1) The slope of the consumption function will be steeper; (2) There will be a movement from left to right along the consumption function; (3) The consumption function will shift parallel upwards; (4) The consumption function will shift parallel downwards.
What is the consumption function? What is the marginal propensity to consume? What does an upward-sloping consumption function mean?
If the marginal propensity to consume increases, that will: Shift the consumption function downwards Lead to the consumption function becoming flatter Shift the consumption function upwards Lead to the consumption function becoming steeper
Consider the Keynesian consumption function Yt =B₁ + B₂x2t + εt ( where yt is per capita consumption, and x2+ is per capita income. The coefficient B₂ is interpreted causally as the marginal propensity to consume, and we expect 0
