Specifically, we assume that the population of this economy is growing so that Nt = nNt−1 for every period t, where n is a constant greater than 1. This says that the number of people born in any period is always n times the number born in the previous period. 05, then the number of people born in each period is growing by 5 percent from generation to generation. ” The gross rate is the net rate plus 1. 1. 2. Trace out the number of young and old people alive in periods 1 and 2. What is the growth rate of the total population?

32 states that the utility-maximizing demand for money occurs where the marginal rate of substitution between first- and second-period consumption equals the rate of return on money. The marginal rate of substitution U1 /U2 , which is the ratio of the marginal utilities in the two periods of life, represents −1 times the slope of the indifference curve at the combination of c1,t and c2,t+1 that corresponds to a given value of qt . 32 is simply a mathematical expression of the statement that utility is maximized where an indifference curve is tangent to the budget line.

At point A, individuals maximize utility given their lifetime budget set in the monetary equilibrium. Point A is found by locating a point of tangency between an indifference curve and the individual’s lifetime budget set line. The rate of return on fiat money determines the slope of the budget set line. In the second period of life, the individual receives no endowment. Hence, when old, an individual can acquire goods for consumption only by spending the money acquired in the previous period. In the second period of life (period t + 1), this money will purchase vt+1 mt units of the consumption good.
