Linear equations for the consumption and saving schedules take the general form C = a + bY and S = -a + (1 - b)Y, where C, S, and Y are consumption, saving, and national income, respectively. The constant a represents the vertical intercept, and b represents the slope of the consumption schedule.a. Use the following data to substitute numerical values for a and b in the consumption and saving equations. b. What is the economic meaning of b? Of (1 - b)? c. Suppose that the amount of saving that occurs at each level of national income falls by $20 but that the values of b and (1 - b) remain unchanged. Restate the saving and consumption equations for the new numerical values, and cite a factor that might have caused the change.
Suppose that when the interest rate on loans is 16 percent, businesses find it unprofitable to invest in machinery and equipment. However, when the interest rate is 14 percent, $5 billion worth of investment is profitable. At 12 percent interest, a total of $10 billion of investment is profitable. Similarly, total investment increases by $5 billion for each successive 2-percentagepoint decline in the interest rate. Describe the relevant relationship between the interest rate and investment in a table, on a graph, and as an equation. Put the interest rate on the vertical axis and investment on the horizontal axis. In your equation use the form i = a + bI, where i is the interest rate, a is the vertical intercept, b is the slope of the line (which is negative),and I is the level of investment.
Q1. Consider the following two-period model of consumption and saving:
Utility = C1^0.5 + B*C2^0.5
C1 + C2/(1+r) = Y1 + Y2/(1+r)
where Y1 = 4, Y2 = 1, r = 0.17 and B = 0.5.
Find a numerical solution for period 1 consumption, C1.
(State your answer to 2 decimal places.)

How consumptions in both periods will change?arrow_forwardConsider the following extract and then answers the questions that follow: How SA's recession is impacting consumer spending Consumers are actively doing pre‐shopping research either through broadsheets or online, and comparing retailers’ offerings to seek out the best value before even leaving the house. Consumers simply no longer purchase certain items, pointing to their extreme need for frugality in current market conditions. Added to this, consumers have also changed the way they use these products in their homes to maximise usage and minimise wastage. This includes the alternative use of products, like using margarine in place of cooking oil and fragranced body lotion instead of perfume. Q1.

- A college professor is planning for his retirement years. His utility function is ?(?t , ?r ) = 3c t 0.5+2cr0.5 where ct represents his consumption today (period 1), his active years of teaching, and cr represents his consumption in his retirement years (period 2). During his active years of teaching, he makes a total of ₺3 million, while in his retirement years his total income is ₺1 million. He can borrow or lend at an interest rate of 25% between the two periods. Write an equation that describes the professor’s budget assuming he will spend all his income during his lifetime. If the professor chooses neither to borrow nor to lend during his active years, what will be his marginal rate of substitution between his consumption today and his retirement years?
