- 4. A consumer’s utility function over leisure and consumption is given by u(L, Y) =LY. Wage rate is w and the price of the composite consumption good is p = 1. (a) Suppose w = 10. Find the optimal leisure - consumption combination. (b) Suppose the overtime wage law is passed so that the firm must pay 1.5 times the normal wage for hours worked beyond the first 8 hours. Find the effect on the hours worked. Decompose the effect into substitution effect and income effectConsider worker 1 with non-labour income Y facing a wage offer w and a utility function defined over consumption and leisure. U(c,l) = lnC + 4lnl a) Derive worker’s income elasticity. Is leisure a normal or inferior good for this worker? b) Provide the functional form of the income effect from a marginal decrease in income. c) Provide the functional form of the substitution and total income effects of a marginal increase in wage.A. Consider a consumer whose preferences can be represented by Cobb-Douglas utility function u(x₁, x₂) = xx where ₁ and 2 are the quantities of good 1 and good 2 she consumes. Let p₁ and p2 be the prices of good 1 and good 2 and let m denote her income. 1. Derive the consumer's Marshallian demand functions. 2. Derive the consumer's Hicksian demand functions. 3. Derive the consumer's expenditure function. 4. Let m = 20, P₁ = 2, and p2 = 1. Suppose that the price of good 1 drops to p₁ = 1. Find the following (a) Compensating variation (CV) (b) Equivalent variation (EV) (c) Change in consumer surplus (ACS) (d) Compare CV, ACS, and EV. 5. Let m = 120, P₁ = 1, and p2 = 1.

- 3. John's utility function is U(C, L) = C1/2L!/2. The most leisure time he can consume is 110 hours. His wage rate is $10. Find John's optimal amount of consumption and hours for leisure and work.Consider the following labor-leisure choice model. Utility function over consumption (C) and leisure (L) U(C.L) = (1/3L1/3 Total hours: H = 40 Labor hours: NS = H - L Non-labor income: π = 30 Lumpsum tax: T = 10 Hourly wage: w = 4 Suppose the hourly wage changes to w = 3. What is the substitution effect of this change on labor supply? A. +2.65 B. -2.65 C. +3.48 D.-3.48 E. None of the aboveThis question will analyze the impact on a person's labour supply from a shock to their partner's job. Assume leisure is a normal good. Let's assume Vanessa has a wage rate of $20 per hour. Recently her partner, Bill, had to take a wage cut at work, with his wage falling from $45 per hour to $30 per hour, but allowed them to continue working 40 hours per week. Analyze the decision of the household over choice consumption and Vanessa's leisure, taking Bill's hours as given (constant).
- A consumer has preferences over bundles of leisure (L) and consumption (z) respresented by the utility function u(L, r) = La and has 24 hours in the day to divide between work and lesiure. This consumer has sorme positive amount of nonwork income per day (m > 0) and is able to select how many hours they wish to work at some positive wage per hour (w > 0). Find the consumer's reservation wage as a function of m: this is the lowest wage at which the consumer will work positive hours. Equivalently, it is the highest wage at which the consumer will work zero hours. (Hint: this is all about the MRS when working zero hours.)Consider the following Labour-Leisure Choice model. Utility function over consumption (C) and leisure (L) 1 3 U(CL) = cL4 Total hours H = 20 Labour hours: N = H-L Non-labour income: 1 = 20 Lump-sum tax T= 10 Hourly wage w = 3 Suppose that the hourly wage increases to 5 What is the substitution effect of this wage change on labour supply(N)? A. -1.10 B. -2.10 O C. +1.10 OD. +2. 10 O E. None of the aboveConsider worker 1 with non-labour income Y facing a wage offer w and a utility functiondefined over consumption and leisureU(c,l) = lnC + 4lnl1) Compare worker 1 with worker 2 whose utility function is described by U(c,l) = cl. Whichworker places a higher value on labour market work?12) Suppose the worker participates in the labour market. Derive worker’s compensated laborsupply function and the compensated labour supply elasticity with respect to wage as a functionof utility level and wage.3) Derive worker’s uncompensated labour supply function (for labour market participants andnon-participants) and the uncompensated labour supply elasticity (for labor market participants)with respect to wage as a function of non-labour income and wage.4) Derive worker’s income elasticity.

- Sharon spends her time (16h) between leisure (L) and work and he consume Y product from his working income (P=1). Assume that she gets W$ per hour of working (W>0) and has the following utility function: U (L, Y) =LY 4Y. a.Calculate the demand function for L. and show it on a graph (L. vs W). b. Calculate the labor supply (H) and show it on a graph (H vs W). c.What will happen to L. Y and H if the wage per hour (W) will decrease?A worker has 110 hours available in a week that can be used for leisure (L) or work (h). The utility function is U = (1 - α)ln(C) + α ln(L), where C is consumption. a) The price per unit of consumption is 1, the hourly wage is w, and the worker has a non-labor income of V. Show that the labor supply is: h* = (110(1-a)- (av)/w). Also, find the demand for consumption and leisure. b) What is the effect on labor supply of i) an increase in the hourly wage and ii) an increase in non-labor income? c) Set α = ½. What are C, L, and h when w = 200 and V = 10000? What is the reservation wage? d) What is the effect on labor supply of i) a 30% income tax and ii) a 10% wealth tax (on V)? e) What is the labor supply if V increases to 11600? f) An increase in V to 11600 gives the worker the same utility as w = 250 and V = 10000 (you do not need to show it). What are the income, substitution, and total effects on labor supply of an increase in wage from 200 to 250 while V remains at 10000?…Consider a consumer who could earn $400 per week and has 50 weeks available each year to allocate between work (H) and nonmarket time (L). They have no non-labour income. Their utility function is U = C2L , where C is the value of consumption goods. What is their optimal choice for the number of weeks in nonmarket time and consumption? Show this in a diagram. Suppose the government introduces a policy that (i) offers no benefits to people who do not work, (ii) offers a wage subsidy on earnings at a rate of 25%, with a maximum benefit of $5000, and (iii) the benefit is subject to reduction at a rate of 25% for every dollar earned above $20,000 in the year. Show the person’s new budget constraint in a new diagram, and discuss how the person’s optimal choice might change (you do not have to calculate this, but point to where it is likely on the new budget constraint). Discuss how income and substitution effects play a role.
