- assume you are given a $100 raise, and decide to save $20 of that money. also assume that if you make zero income in a year, you will still spend $7000. a.) what is your consumption function? b.) if you earn $20000 in a year how much will you spend? c.) will you be able to save while earning the above income?Equation for consumption is C=40/(0.8Y) where Y= yearly income = $400. A) what is the level of consumption B) what is the average propensity to consumeIn an economy the savings function is given to be as:- C = 1000 + 0.75Y Where C is the Consumption Expenditure and Y is the national income. Derive the saving function
- Suppose that the linear equation for consumption in a hypothetical economy is C = 40 + .8Y. Also suppose that income (Y ) is $400. Determine (a) the marginal propensity to consume, (b) the marginal propensity to save, (c) the level of consumption, (d ) the average propensity to consume, (e) the level of saving, and ( f ) the average propensity to save.a) Draw a consumption function and label the axes.b) Suppose that your friend has a consumption function of the form y=1.4x+200. Is this function sustainable in the long run? Why or why not?c) Suppose that your consumption function is y=0.75+1000. What is your marginal propensity to consume? What is your autonomous expenditure?d) State the permanent income hypothesis.e) Suppose that I raise your income today by $10, and lower it tomorrow by $10. How would your behavior change according to the consumption function (aka Keynesian, aka rule-of-thumb) model? And what about according to the permanent income hypothesis model?The slope of the consumption function is positive and equals 1-MPC True False
- Find the equilibrium level of GDP (income or V) demanded in an economy in which investment (1) is always $300, net exports (X-IM) are always - 550, government expenditures (G) and taxes (T) are each equal to $400, and the consumption function is described by the following algebraic equation: C = 150 + 0.75Dl DI is disposable income. How much saving (5) is there at the equilibrium level of income. Hint: (1) Dl = Y (national income or GDP) minus taxes (Y-T) (2) Income (Y) not consumed (C) must be saved (S). This means that S = Y-C. (3) to answer this you have to set Y=AE or Y=C+1+G (X-IM), and solve for Y. Then you have to solve for S.Assume that that tax revenues (T) are proportional to income (Y). That means if the tax rate is equal to t, then we have T = tY.Also, consumption (C) and investment (I) functions are given as the following: C = a + b (Y – T) [where a and b are constant]I = c – dr. [where c and d are constant, and r is the interest rate] A) Find the expression of the government purchase multiplier. (Use derivative) B) What will happen to multiplier if tax rate increases? What will happen to multiplier if MPC increases?Find the value of MPC when multiplier is stated as 0.97
- Construct a consumption function from the data given here and determine the MPC. Given the consumption function in the above question, what is the relationship between disposable income and consumption? Is it direct or indirect and then explain what it means.6. Given the savings function S = (3Y2 +2Y)/ ( Y-1) a) Write the consumption function. b) Find the equilibrium level of income, if the consumption is 100. Please answer both subparts. I will really upvote7. If the consumption function is given by C = 0.62Y + 50 state the values of (a) autonomous consumption (b) marginal propensity to consume Transpose this formula to express Y in terms of Cand hence find the value of Y when C = 120.
