A country is closed. It has no government sector, and its aggregate price levels and interest rates are fixed. Furthermore, the marginal propensity to consume is constant and the country's consumption function is as follows: C = 200+ 0.75 YD, where YD is disposable income and Cis consumption. Assume that planned investment equals 75. If this country's income increased by $10,000, consumption would increase by: A) $10,000. B) $7,500. C) $200. D) $7,700.

Assume in country Y, the average marginal propensity to save is 0.2. When the aggregateincome is zero, consumers spend 50 to consume. Derive the saving function and consumptionfunction for this country. What happens to consumption when the propensity to savedecreases to 0.1? Explain your answer and show this on the graph.
You are an economic advisor to the government. Discuss your opinion . a) How COVID-19 pandemic will affect the consumption behavior as well as the investment done by the firms and household for the next two years? b) What are the actions or policies that the government can implement to face this situation? please answers with analysis and --graph (if possible)
Assume there are 2 people Xavier with a Marginal propensity to consume (MPC) of 80% and Francis with a Marginal Propensity to save (MPS) of 10%. Xavier enjoys life and has a minimum consumption of $10,000 without any income, while Francis is more modest, with a minimum consumption of $7,500 without any income. a. Demonstrate and explain the income expenditure model for Xavier and Francis on separate graphs with income ranging from 0 to $100,000 in $20,000 increments. b. Compare the minimum income levels where savings begins for Xavier and Francis. c. How does the difference in MPC affect the economies for each state? d. If the government decides to take all savings above $2,000, is this fair to Xavier? Francis? e. How might this change their behavior? How is this relevant to discussions about wealth inequality? How are individual choices relevant to wealth inequality?
these 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…
If Andrea’s disposable income increases from $600 to $700 and her level of personal consumption expenditures increases from $450 to $475. You may conclude that her marginal propensity to consume is: Group of answer choices 0.5 0.1 0.75 0.25
Describe how the endogeneity versus exogeneity of consumption expenditures (i.e., the household sector) affects the size of predicted output multipliers by an input-output model.

Suppose that Jane’s income increases from $1700 per month to $2350. At the same time, her consumption changes from $950 per month to $1300 month. What is Jane’s marginal propensity to consume? (Round your answer to two decimal places.)
We again assume asimple closed economy with GDP of 100 and:c0(autonomous consumption) = 20c1 (marginal propensity to consume) = 0.6I (investment) = 20.a) Now assume that c0falls by 5 (i.e. 5% of GDP), i.e. for any given level of output,consumption will fall by 5. Show the implied fall in the AD function in yourdiagram and show that output will fall by more than 5.b) Show that the multiplier is equal to 2.5, and hence that, in the new equilibrium,output will have fallen by 12.5 (i.e. by 12.5%)c) How big would the impact be if, say, c1 = 0.4 or c1 = 0.8? Explain the difference.

Please no written by hand solutions Data on before-tax income, taxes paid and consumption spending (on domestic goods and services) for the Simpson family in various years are given below. BEFORE-TAX INCOME ($) TAX PAID ($) CONSUMPTION SPENDING ($) 3000 3500 3700 4000 25 000 27 000 28 000 30 000 20 000 21 350 22 070 23 600 a. Graph the Simpsons's consumption function and find their household's marginal propensity to consume. b. How much would you expect the Simpsons to consume if their income was $32 000 and they paid taxes of $5000? c. Homer Simpson wins a lottery prize. As a result, the Simpson family increases its consumption by $1000 at each level of after-tax income. ('Income' does not include the prize money.) How does this change affect the graph of their consumption function? How does it affect their marginal propensity to consume?
Write down the Planner’s problem, as well as the Lagrangian. (Hint: There should be two constraints because aggregate consumption of each good cannot exceed the economy’s endowment.) Label the multipliers ϕ1 and ϕ2. What are the first order conditions of the Planner’s problem? (Hint: There should be 6.). Find the solution to the Planner’s problem and label the quantities (xpA; ypA) and (xpB; ypB). If we compare the first order conditions of the Planner’s problem to the first order conditions of a corresponding competitive equilibrium (CE), we can obtain a relationship between ϕx, ϕy, λ, px, and py so that the CE and the Planner’s problem give us the same solution. This is called decentralizing the Planner’s problem.Decentralize the Planner’s problem. (find the equilibrium prices and the value of λ so that the two problems have the same solution.) Can you relate this to the two welfare theorems?
