[size=11.000000pt]Suppose [size=11.000000pt]n [size=11.000000pt]= 1. Suppose the endowment grows, i.e. [size=11.000000pt]ω[size=8.000000pt]t [size=11.000000pt]= ([size=11.000000pt]y[size=8.000000pt]t[size=11.000000pt], [size=11.000000pt]0) where [size=11.000000pt]y[size=8.000000pt]t [size=11.000000pt]= [size=11.000000pt]Ay[size=8.000000pt]t[size=8.000000pt]−[size=8.000000pt]1[size=11.000000pt], and [size=11.000000pt]A > [size=11.000000pt]1 is aconstant. Also, [size=11.000000pt]ω[size=8.000000pt]1 [size=11.000000pt]= ([size=11.000000pt]y,[size=11.000000pt]0). There is a constant amount of fiat money [size=11.000000pt]M[size=11.000000pt]. Suppose the preferences of generations 1, 2, ..., are
u(c1, c2) = √c1 + √c2, and those of the IO are uIO(c2) = c2.
- Write down equations that represent the budget constraints in the first and second periodof a typical individual from generation [size=11.000000pt]t. Combine these constraints into a lfetime budetconstraint of this individual.
- Restrict attention to a stationary solution in which each generation would consume the samefraction of its endowment when young. Write down the conditions that represents the clearingof the money market in an arbitrary period [size=11.000000pt]t. Use condition to find the real rate of return offiat money in a monetary equilibrium. Explain the path over time of the value of fiat money.
- Find the Golden Rule allocation for this economy.
- Find the optimal ([size=11.000000pt]c[size=8.000000pt]∗[size=8.000000pt]1[size=8.000000pt]t[size=11.000000pt],c[size=8.000000pt]∗[size=8.000000pt]2[size=8.000000pt],t[size=8.000000pt]+1). Compare it with the Golden Rule allocation found above.
