Assume an economy in which:(i) there are no exports and no imports,(ii) investors always want to spend $200 billion, or I = 200,(iii) government spends $500 billion and tax revenue is $200 billion,(iv) consumption is a linear function of disposable income, C=100+0.8Yd
What is the saving equation? Please answer briefly
Consider an economy described by the following equations:
Y = C+I+G
Y = 5000
G = 1000
T = 1000
C = 250 + 0.75(Y-T)
I = 1000 - 50r
In this economy, compute private saving, public saving, and national saving.
Find equilibrium interest rate.
Now suppose that G rises to 1250. Compute private saving, public saving, and national saving.
Find the new equilibrium interest rate.
Using your knowledge of Macroeconomics and intuition explain the reason why increasing government expenditure causes interest rate to rise?
If the government wants to increase the amount of savings in the economy, how should it alter government spending? What effect will this action have on the interest rate in the economy?
Explain the difference between saving and investment as defined by a macroeconomist. Which of the following situations represent investment and which represent saving? Explain.a. Your family takes out a mortgage and buys a new house.You use your $200 paycheck to buy stock in Africel.Your roommate earns $100 and deposits it in his account at a bank.You borrow $1,000 from a bank to buy a car to use in your pizza delivery business.The interest rate is 7 percent. Use the concept of present value to compare $200 to be received in 10 years and $300 to be received in 20 years.A company has an investment project that would cost $10 million today and yield a payoff of $15 million in 4 years.Should the firm undertake the project if the interest rate is 11 percent? 10 percent? 9 percent? 8 percent?Can you figure out the exact cutoff for the interest rate between profitability and nonprofitability?

- 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.arrow_forward1. Assume in a simple economy that the level of saving is –500 when aggregate output equals zero and that the marginal propensity to save is 0.2.
