Indentify if the following statement is true or false, and explain.
If consumption is given by C = a + b(Y − T) and investment is given by I = f − hr, then a tax cut has no effect on equilibrium investment in the long run in the loanable funds model.
Answer : The answer is False.
Income = Consumption + Saving
=> Saving = Income - Consumption.
Here due to tax cut the T (tax) is deducted in consumption function. Due to tax cut the consumption expenditure falls which increase the savings. We know that,
Savings = Investment
As here savings increases due to tax cut hence investment will increase in long-run because savings is always equal to investment. This means that tax cut effect the long run equilibrium investment in loanable funds. Therefore, the given statement is false.

question 4 4. This question concerns how the consumption function affects the analysis of the loanable funds market. Suppose consumption depends on the interest rate, i.e. C = C(Y - T,r). a. b. How will a rise in interest rate affect consumption expenditure and thus national saving? Explain how an increase in government expenditure would affect the economy in the long-run. In particular, explain the effects on investment and consumption. Suppose there is an increase in investment incentive because of...
function is given by I = 900 - 280r. Th Problem 4 (25 points). In a closed economy in the long run, real closed economy in the long run, real GDP is Y = 2000. The investment is given by / 900 - 280r. The real interest rater is measured in percentage points (e.g. for 5% and not 0.05). The consumption function is c 200 + 0.5Y - 20r. Here YD is disposable income. Currently, net taxes consititute 20% of...
Macroeconomics (consumption, investment and loanable funds) question. The Current U.S. government spending is $4.746 trillion. That's the federal budget for fiscal year 2020 covering October 1, 2019, to September 30, 2020. It's 21% of gross domestic product. That means that Government Spending in the United States has increased under the current U.S. Administration. Additionally, last year the Congress passed a tax reform that, among other effects, cut payroll taxes: i) Can you establish the macroeconomics effects of these policies on...
TRUE-FALSE-UNCERTAIN For each of the following claims, indicate whether it is true or false, or whether it could be either one, depending on circumstances. Then, explain why. Your grade will depend on your explanation. Try to make sure your explanation is not only correct but thorough. In particular, if a statement is false for more than one reason, discuss all those reasons (even though, logically, it takes just one contradiction to make the entire statement false). Doing this will prepare...
2. The country, Hoosier (a closed economy), has the following data: GDP: Y = 1200, Consumption: C = 600 – 10,000 r, Taxes: T = 200, Government purchases: G = 300. The investment is I = 700 – 10,000 r a. Use the information above to find the supply and demand equations for loanable funds: i. Supply equation: ii. Demand equation: _ b. What is the equilibrium interest rate, r, and what are national saving and investment, S and I?...

1. True, False or Uncertain: For each of the following statements determne if the statement is TRUE, FALSE, or UNCERTAIN. You must justify your answer either graphically or algebraically. No credit will be given without an explanation. a. "Suppose that the CPI in Japan in 2015 is equal to 180 and the CPI in the United States in 2015 is equal to 165. Then the inflation rate in Japan was higher than the U.S. inflation rate between 2014 and 2015."...
Use the model of loanable funds to answer the following questions: In the long-run, how does a increase in taxes affect the real interest rate (r)? Include the appropriate diagram. How does the policy affect the levels of (i) national income (Y ), (ii) consumption (C), and (iii) investment (I)? How do you know?
