33.Louisa works for a hedge fund company. Her wage increased from $30 per hour to $40 per hour. She can work up to 50 hours each week. Louisa is currently working 10 hours per week and receives 84 utils for the leisure time she enjoys. If she decides to work 20 hours instead, her total utility of having only 30 hours of leisure is 71 utils. Her total utility from the income she receives working 10 hours per week is 74 utils and her total utility from the income she receives working 20 hours per week is 110 utils. If she decides to work 30 hours then her marginal utility gain from having more income will now be:

Multiple Choice

a.74.

b.36.

c.13.

d.12.

Aleah is currently working 30 hours per week and receives 54 utils for the leisure time she enjoys. If she decides to work 20 hours instead, her total utility of having 30 hours of leisure is 73 utils. Her total utility from the income she receives working 30 hours per week is 122 utils and her total utility from the income she receives working 20 hours per week is 113 utils. If she decides to work 30 hours, her marginal utility loss from having less income is:

Homework Answers

Answer #1

1) Option A is correct because with increase in income expenditure on music festival is also increasing that is there exist a positive relationship between income and Music festival demand

income elasticity = 100%/25% = 4

2) Option D is correct because cross price elasticity shows that how demand of one good changes when prices of another good changes , here it is negative which shows that goods are complementary and Good y and Good z are normal good because of positive income elasticity .

3) option B is correct

MU = 110-74 =36

5) option A is correct

TVC = TC-TFC

  = 54-24

6) Option A is correct

TFC = AFC*Q =15*2 = 30

TC = TVC+TFC = 30+24=54

7) Option A is correct

TVC = AVC*Q = 12*2 = 24

Suppose that a worker’s utility (i.e., preferences) with respect to total income (Y) and hours of leisure time per week (LT) can be represented by the following Cobb-Douglas utility function: U = Y0.4 ∙ LT0.6 (note: A=1; α=0.4; β=0.6) Assume that the market wage is $25 per hour of work (H), and his/her non-labor income is $300 per week.

Brittanys preferance for money income and leisure can be exoressed as U(Y,L)= (Y-200)*(L-50). This utitlity function implies that Brittany's marginal utility of leisure is (Y-200) and her marginal utility of money income is (L-50). There are 168 hours in the week available to split between work and leisure. Brittany earns $20 per hour after taxes. She also recieves $400 worth of welfare benefits each week regardless of how much she works. A) Graph Brittany budget line. B) Find Brittanys optimal...

In the labor-leisure model, the representative consumer receives satisfaction from consumption of goods (C) and from the consumption of Leisure (L). Let C be the composite good with price $1 and L determines the number of hours of leisure this person consumes. Therefore U = f(C,L) for this consumer. This consumer’s consumption is constrained by time and income. Let her non-labor income, V, be $1200 per week, let the hourly wage rate be $8 and h be the number of...
