Consider a consumer’s consumption-saving decision in a two-period model. Suppose that the real interest rate is r. This consumer’s current income is y and the future income is y’ . The government imposes lumpsum taxes t and t’ in the current period and future period, respectively. In addition, the government subsidizes savings with rate q: the consumer needs to pay 1 /(1+q) to save one unit of consumption. That is, the budget constraint of the current period is c + s/( 1 + q) = y − t.

(a) (10 points) Derive the lifetime budget constraint. Graphically illustrate this person’s budget constraint, endowment point, and optimal choice. Assume that this consumer is the lender (saver).

(b) (10 points) What will be the effects of decreasing q on (c, c’ , s), respectively? Assume that this consumer remains as the lender, and the substitution effects are dominating. Explain.

Expert Solution

In this solution, we have considered the subsidized savings and solve the sum with two period model.

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

In the two-period model of consumption, suppose that the first period income is $5,000 and the second period income is $5,500 for both Jill and Jack. The interest rate is 10 percent. Jack’s lifetime utility function is ?1 + ?2 while Jill’s lifetime utility function is ?1 + 0.8?2. 1)Draw a graph that represents the common budget constraint that Jill and Jack face. 2)Draw indifference curves of Jill and Jack in separate graphs and compare the slopes of the indifference...

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 the two-period Neoclassical consumption model seen in class. Suppose that income is measured in dollars. Let the utility function take the logarithmic form U(C)=ln C, and the representative consumer maximize her lifetime utility subject to her budget constraint. Suppose that income in period 1 is $50,000, income in period 2 is $30,000, ?=1 and ?=5%. Do you think that the consumption profile of the agent in this numerical example is going to be smoother than her income? If so,...

1. Suppose that Americans decide to increase their saving. As a result, the real interest rate will (Rise/Fall) , and U.S. net capital outflow will (Increase/Decrease) . 2. If the elasticity of U.S. net capital outflow with respect to the real interest rate is very low, this increase in private saving will have a (Large/Small) effect on U.S. domestic investment. 3. If the elasticity of U.S. exports with respect to the real exchange rate is very high, this increase in...

Consider a two-period consumption model where an individual has income It > 0 in period t and the (net) interest rate is r > 0. However, suppose the price levels are not assumed to be 1. Instead, let p2 ≥ p1 > 0. (a) Derive the lifetime budget constraint. (b) What is the slope of the lifetime budget line? Letting 1 + π = p2/p1 bethe gross inflation rate, given an interpretation of the magnitude of them budget line. (c)...

Consider the following two-period Fisher model of consumption. Jamil earns $600 in the first period and $0 in the second period. The interest rate is 10 percent. His lifetime utility function is log(?1 ) + 0.5log(?2). a) Find the optimal values of ?1 and ?2. Answer: ?? = ???, ?? = ??? b) Suppose that the lifetime utility function changes to log(?1 ) + log(?2). Calculate the new optimal values of ?1 and ?2. How is the optimal value of...

1. Consider Irving Fisher’s two-period model of consumption. Suppose that the consumer also pay’s taxes T1 in the present, T2 in future. a. Derive the inter-temporal budget constraint of the consumer. b. Draw a graph that would represent optimization of consumption. Label the graph clearly. c. Suppose future taxes decrease to T’2. Using a graph, show the effect of this on optimal consumption. Show in a new graph d. Suppose the consumer’s future income increases to Y2 to Y’2, as...

Two period saving model) Consider an economy populated by identical people who live for two periods. They have preferences over consumption of the following form: U=ln(c1) +βln(c2), where ct denotes the stream of consumption in period t. They also receive an income of 50 dollars in period 1 and an income of 55 dollars in period 2. They can use savings to smooth consumption over time, and if they save, they will earn an interest rate of 10% per period....

Consider the consumer’s optimization problem in the one-period model. Utility is: u ( c , l ) = ln ⁡ ( c ) + γ ln ⁡ ( l ) where c is consumption of goods, l is leisure, and γ is a constant. The consumer’s nominal budget constraint is: P c = W ( h − l ) where P is the price of goods; W is the nominal wage; and h is the total hours in the period....
