Consider the following model of labour supply. There is a representative worker with the following utility function: U(C, L) = CªL*-a %3D where U is utility, C is consumption, L is leisure, and a is a parameter that governs the importance of consumption to the worker's utility relative to leisure. a must satisfy 0 < a < 1. Consumption and Leisure are always positive (by definition) The budget constraint and time constraint are: C = wh + V h = T – L where w is hourly wage, and V is non-labour income, T is time endowment. Here, w,V and T are parameters. h is hours work

Question
Consider the following model of labour supply. There is a representative worker
with the following utility function:
U(C,L) = CªL²-a
where U is utility, C is consumption, L is leisure, and a is a parameter that governs
the importance of consumption to the worker's utility relative to leisure. a must
satisfy 0 < a < 1. Consumption and Leisure are always positive (by definition)
The budget constraint and time constraint are:
C = wh + V
h = T – L
where w is hourly wage, and V is non-labour income, T is time endowment. Here,
w,V and T are parameters. h is hours work
a) Does the utility function exhibit the "the more the better" and "law of
diminishing marginal utility" assumptions? Show it.
b) Characterize the optimal leisure and consumption as functions of the
parameters a, w, V and T
