Q.c) Which type of consumer (lender or borrower) becomes better off after the interest rate change? Explain in words.

Ans-

The borrower becomes the better consumer after the interest rate change. The interest rate is a big factor for the borrowers,i.e. when the rate of interest decreases then the borrower pays less interest, which gives them plenty of money to expand, which generates a ripple effect throughout the economy of increasing spending.

Q. Suppose the real interest rate falls in the two-period model (where income and taxes are exogenous). Consider the income and substitution effects and explain in words and through diagrams how this change affects current consumption, future consumption, and savings of a consumer who is a

a) lender

b) borrower

Ans-

Optimal consumption bundle is at the tangency of indifference curve to budget constraint
At Figures, the endowment point is at E, but the consumer chooses to point A
At Point A
MRSc1,c2=1+r
Consumer lends distance DB that is s1=y1-t1-c1*>0(fig 1)
Consumer borrowers distance DB that is s1=y1-t1-c1*<0(fig 2)

Suppose that, in the basic one-period model, there is no government spending and no taxes. Production by the representative firm produces pollution in proportion to the amount of output produced. Given any consumption bundle (a consumption-leisure pair), the consumer is worse off the more pollution there is. (a) In a diagram, show the competitive equilibrium and the Pareto optimum. Show that the competitive equilibrium is not Pareto optimal, and explain why. Is more or less output produced in the competitive...

A more realistic depiction of the two-period consumption model would have a different interest rate for savers and borrowers. Think about it. The rate you pay for a student loan or a home mortgage (when you are a borrower) is much higher than the rate you earn on a savings account at a bank (when you are a saver/lender). 1 Let r S be the interest rate for a saver and r B be the interest rate for borrower, such...

Consider a two-period model of mineral extraction with a 3% discount rate, in which the total supply of minerals is fixed at 100. A social planner is trying to decide how much we should consume in each period (i.e. what the efficient consumption pattern would be). Q1 is our consumption in period 1; Q2 is our consumption in period 2. Prices (P1), marginal benefits (MB1), and marginal costs of extraction (MCE1) in period 1 are: P1 = MB1 = 80...
