Suppose that the utility function is U(c, l) = c^(a) l^(1−a) where < a < 1. Calculate the slope of an indifference curve for this utility function. What happens to the slope of the indifference curve when c decreases and l increases? Explain.
Solutions
Expert Solution
Utility function is;
U(c,I) = ca I(1-a)
Marginal rate of substitution
MRS is the rate at which consumer is willing to give up some units of one good in order to gain 1 more unit of other good. It represents the slope of the indifference curve and is calculated as;
MRS = MUc / MUI
= aca-1I(1-a) / (1-a)ca
I-a
= aIa I1-a / (1-a)ca
c1-a
= aI / (1-a) c
MRS = aI / c - ac
When c decreases it means that MRS will increase, i.e slope of the indifference curve will increase and at the same time when I increases, MRS will increase i.e slope of the indifference curve will increase.

Suppose a worker's utility function is U(C, L) = C^2 +(2nL)^2 ,
where C denotes consumption and L leisure. Let T denote time
available to split between leisure and work, w denote the wage rate
and V = 0 denote non-labor income (as in the lecture).
(a) What is the worker's optimal choice of C and L as a function
of w, T, and n?
(b) What is the worker's reservation wage as a function of T and
n?

Consider an economy where the representative consumer has a
utility function u (C; L) over consumption C and leisure L. Assume
preferences satisfy the standard properties we saw in class. The
consumer has an endowment of H units of time that they allocate to
leisure or labor. The consumer also receives dividends, D, from the
representative Örm. The representative consumer provides labor, Ns,
at wage rate w, and receives dividends D, from the representative
Örm. The representative Örm has a...

Suppose that an individual has a utility function of the form U
= Y½ where U is utility and Y is income.
a) Calculate the utility level for Y values of $10,000,
$40,000, $90,000, $160,000, and $250,000 and then plot the
individual’s total utility function.
b) This individual is currently earning $90,000 but has
a 50-50 chance of earning either $40,000 or $160,000 in a new
job.
i) Calculate the expected income and utility from the

accident that will cost him $30,000.
