Problem 1 Consider the following two-period utility maximization problem. This utility function belongs to the CRRA (Constant Relative Risk Aversion) class of functions which can be thought of as generalized logarithmic functions. An agent lives for two periods and in both receives some positive income. subject to +6+1 4+1 = 3+1 + (1 + r) ar+1 where a > 0,13 € (0, 1) and r>-1. (a) Rewrite the budget constraints into a single lifetime budget constraint and set up the...
Consider an economy occupied by two households (i- A, B) who are facing the two-period consumption problem. Each household i - A, B is facing the following utility maximization problem: max subject to ci +biy(1+r)bo where Vi and US are household i's exogenous income in period t 1.2. cỈ and c are household i's consumption in period t 1,2. bo,bi is household i's bond holdings of which bo is exogenously given, r is the real interest rate, and 0 <...
2. Consider the following four consumers (C1,C2,C3,C4) with the following utility functions: Consumer Utility Function C1 u(x,y) = 2x+2y C2 u(x,y) = x^3/4y^1/4 C3 u(x,y) = min(x,y) C4 u(x,y) = min(4x,3y) On the appropriate graph, draw each consumer’s indifference curves through the following points: (2,2), (4,4), (6,6) and (8,8), AND label the utility level of each curve. Hint: Each grid should have 4 curves on it representing the same preferences but with different utility levels. 3. In the following parts,...
Consider the following statements.
(i) The Laplace Transform of
11tet2 cos(et2)
is well-defined for some values of s.
(ii) The Laplace Transform is an integral transform that turns
the problem of solving constant coefficient ODEs into an algebraic
problem. This transform is particularly useful when it comes to
studying problems arising in applications where the forcing
function in the ODE is piece-wise continuous but not necessarily
continuous, or when it comes to studying some Volterra equations
and integro-differential equations.

Consider the following investment strategies: a. Buying and holding an n-year zero-coupon bond b. Buying an (n-1)-year zero-coupon bond and rolling over the proceeds into a 1. year bond Under certainty, the yield curve suggests that neither entails any risk and so both strategies must provide equal returns. Mathematically, this can be expressed as (1 + Yn)" = (1 + Yn-1)-1 X (1+ (1) where n denotes the period of maturity, Yn is the yield to maturity of a zero-coupon...
