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?
What of the following summarises the the paradox thirft?
a. if all people reduce their consumption, the additional saving makes higher investment possible.
b. if all people try to increase their saving simultaneously then consumption, income and emplyment will fall but the volume of saving will remain unchanged.
c. higher saving is required to achieve higher investment.
d. the proprotion of national income saved decreases if the marginal propensity to consume decreases.
