At a workers utility maximizing level of leisure and income, their marginal utility with respect to leisure is 5, their marginal utility with respect to income is X, their hourly wage is $6, and their non-labor income is $50. What must X equal?
Answer
Lets first find budget constraint :
Y = wH + Yo
where Yo = non labor income = 50, w = hourly wage = 6, H = Total labor hours worked
L + H = T where L = leisure, T = Total time available
=> Y = 6(T - L) + 50
=> Y + 6L = 6T + 50
We can consider as budget constraint and thus Price of Y = 1 and Price of T = 6
Utility maximizing condition :
In order to maximize utility a consumer consumes that quantity at which Marginal Utility / Price of all goods are equal.
Here, (Marginal Utility / Price) of Leisure = 5/6 and (Marginal Utility / Price) of Income = X/1
According to above utility maximizing condition :
5/6 = X/1 => X = 0.83 and Hence X = 0.83

4. Let a person's utility function over consumption, X, and leisure, L, be given by U = XL2, SO MUx = L2 and MUL = 2xL.The individual may work up to 24 hours per day at wage rate, w = $10 per hour, and he has non-labor income of $50 per day. The price of x, px, is $5. (a) Find the utility-maximizing x and L. (b) Show that at the utility- maximizing quantities of x and L, the consumer's...
Assume that a consumer’s satisfaction depends upon leisure (L) and income (Y), so that the utility function is: U = 48L + LY – L2 Let N denote the hours of work by the consumer and W the hourly wage rate. Consequently, Y = WN and L + N = 24. If the hourly wage rate is $15 per hour: a) What are the utility maximizing hours of leisure, L*? b) What are the utility maximizing hours of work, N*?
Clark gains utility from consumption c and leisure l and his preferences for consumption and leisure can be expressed as U(c, l) = 2(√ c)(l). This utility function implies that Clark’s marginal utility of leisure is 2√ c and his marginal utility of consumption is l √ c . He has 16 hours per day to allocate between leisure (l) and work (h). His hourly wage is $12 after taxes. Clark also receives a daily check of $30 from the...

13) Consider the standard labor-leisure choice model. Consumer gets utility from consumption (C) and leisure (L). She has H total hours. She works N S hours and receives the hourly wage, w. She has some non-labor income π and pays lump-sum tax T. Further suppose (π – T) > 0. The shape of utility function is downward-sloping and bowed-in towards the origin (the standard U- shaped case just like a cobb-douglas function) If this consumer decides to NOT WORK AT...
Suppose a consumer values income (m) and leisure (l) with utility function U(m,l)=ml. The consumer has T hours per week to allocate between labor and leisure with an hourly wage rate of w. The consumer's weekly time constraint is (m/w)+l=T. Use a Lagrangian to maximize the consumer's utility subject to the weekly time constraint. What is the optimal amount of leisure? what is the optimal amount of labor (L=T-l)

Consider the utility function u (c, o) = oc (o = leisure; c = consumption), determine the optimal amount of consumption and leisure if the consumer can work at most 24 hours, the hourly wage is 5 and the price of each unit of consumption is 2. There is no initial income endowment.
