Consider the following model of a very simple economy. Household saving and investment behavior depend in part on wealth (accumulated savings and inheritance). In the late 1990s many were oncerned with very large increases in stock values (a form of wealth) and its possible effect on saving and investment. The following consumption function incorporates wealth (W) as a determinant of consumption. We have the following information on consumption (C) and investment (1): • C= 40 +0.75Y+0.07W • 1 = 100 • W = 1,000 We are ignoring the fact that saving adds to the stock of wealth. Calculate the values of equilibrium Y, C, and saving (S). (Enter your responses as integers.) = $ 840 C = $ 740 6= $ 100 uppose that wealth increases by 60 percent.

Scenario 2: An investment tax credit effectively lowers the tax bill of any firm that purchases new capital in the relevant time period. Suppose the government repeals a previously existing investment tax credit. Shift the appropriate curve on the graph to reflect this change. The repeal of the previously existing tax credit causes the interest rate to and the level of investment to
You are given the following consumption function: C = RM150 million + 0.75Yd Based on the above consumption function, answer the following questions: How much is: Autonomous consumption Autonomous saving How much is the disposable income when saving is zero? If there an investment of RM200 million, what will be the new equilibrium level of income.

Consider the following two-period model of consumption and saving: Utility In(C1) + In(C2) C1 C2/(1+r) Y1 + Y2/(1+r) where Y1 = 4, Y2 = 7 and r = 0.14. Find a numerical solution for period 2 consumption, C2. (State your answer to 2 decimal places.)
Consider a two-period consumption saving model and let ci and c2 denote the first and second period consumption, respectively. Assume that the interest rate at which the consumer may lend or borrow is 10%. Suppose that a consumer's utility function is u (C1, c2) = c1 + 20 c2. The consumer first period income is I1 = $100 and the present value of her income stream is $330. (a) What is the optimal consumption stream (consumption bundle) of this consumer? (b) Is this consumer borrower or lender? How much does she borrow or lend? (c) What is the effect of a reduction of the interest rate to 5% on the consumer's optimal first-period saving? (Make sure to take into account the effect of the decline in the interest rate on the present value of the consumer's income stream.)
