A: Answer to the question is as follows:
Assume you can work as many hours
you wish at £12 per hour (net of tax). If you do not work, you have no
income. You have no ability to borrow or lend, so your consumption, c, is
simply equal to your income.
Now assume that you receive an income of £140 per week from an unknown benefactor. Show the impact on your feasible set, and show a new optimal choice in which consumption increases but labour supply decreases. Using the concept of the marginal rate of substitution, explain why this is a likely outcome.

- A worker receives, when unemployed, an offer to work forever at wage w, where w is drawn from the distribution F(w). Wage offers are identically and independently distributed over time. The worker maximizes Where ct is consumption and lt is leisure. Assume Rt is i.i.d. with distribution H(R). The budget constraint is given by And lt + nt ≤ 1 if the worker has a job that pays wt. If the worker is unemployed, the budget constraint is at+1 ≤ Rt(at + z − ct) and lt = 1. Here z is unemployment compensation. It is assumed that u(·) is bounded and that at , the worker’s asset position, cannot be negative. This assumption corresponds to a no-borrowing assumption. Write the Bellman equation for this problem.All individuals have the same utility function over consumption, C, and leisure, L, given by U = C1/3L2/3, Denote the wage rate by w. The total time available for labour and leisure is equal to 12. The price of consumption is PC=1. Denote the amount of labour supplied as N. 1)Find the Labour supply function. 2)The government introduces a tax t=0.2 on wage, such that the after-tax wage is (1-t)w. How much tax revenue does the government collect on everyone? What is the effect on labour supply? 3)The government chooses instead to collect a fixed lump-sum T from everyone. What is the effect on labour supply?Consider the utility function for a worker according to leisure, l, and consumption, c: where consumption has the price p and the wage has the price w. The state can implement an income tax, t, for the worker where 0 < t < 1 such that his after-tax hourly wage is w(1 - t). What is the biggest tax revenue that the state can get?
- Consider a single mother with the utility function U = 2/3 log(x) + 1/3 log(), where x is consumption and is leisure. The mother can work up to 100 hours per month. Any of the 100 hours that are not worked are leisure hours. She earns a wage of $10 per hour and pays no taxes. The consumption price is normalized to $1. To be able to work, she has to incur a child care cost of $5 for every hour worked. a. Suppose that there is no tax and welfare benefits. How many hours will she work and what will be her consumption level? Draw the graph depicting her budget set with consumption on the vertical axis and leisure on the horizontal axis. b. Suppose that the government introduces a negative income tax (NIT) that guarantees an income of $200 per month. The benefit is taken away one for one as earnings increase. Draw the new budget set. Compute the new number of hours worked and consumption level. Has consumption increased and is the mother better off? Why or why not? c. Now…Assuming that the substitution effect is large relative to the income effect, tax reform designed to increase saving a. increases the interest rate and decreases spending on capital goods. b. increases the interest rate and increases spending on capital goods. c. decreases the interest rate and increases spending on capital goods. d. decreases the interest rate and decreases spending on capital goods.Suppose that following represents the utility function of the individual U(c,l)=log(c)+log(l) c = consumption level of the individual and l = leisure, while the market wage is 10 and available time is 20. 1) Find and draw the labor supply function. 2) Suppose that the government introduces a cash grant for the labor (who is in the labor force) in the amount of R. Find and draw the labor supply function? Compare it to the labor supply function you have found in a). 3) Discuss the existence of reservation wage in the settings described in a and b? If your answer is : “there are no reservation wages under those settings”, please introduce a change in the policy described in b) to make sure that the reservation wage would exist.
- A worker receives a wage rate w and has L hours of leisure every day (the total endowment of hours is 24 hours per day). The government gives a subsidy of rate S of his income. The worker spends all his income. 1. Write a budget constraint of this individual and plot it. 2. Display graphically what is the optimal consumption-leisure choice for this worker. 3. Imagine that instead, the government imposes income tax at rate T . What is the new budget constraint? Display on the same picture. In the new optimum is the consumption higher? Explain the answer in terms of wealth and substitution effects.The weekly preferences over consumption (C) and leisure(L) are defined by u(C, L) = √C + 3√L. The person receives a weekly allowance of m from The hourly wage is $18 per hour, and the person can work up to50 hours each week (T = z + L = 50), where z is the number of hours spent working). a)How many hours will the person work if her allowance is m= $450 per week b) What is the smallest allowance m for which the person will stopworking altogether (z∗ = 0) for a wage of w = 18?Consider the following model of a competitive labour market where both firms and workers have perfect foresight and symmetric information about the price level (that is, no misperceptions). Firms' technology is given by the production function y = a N ½ (production function) where a is a positive constant representing total productivity, N is employment and the elasticity of production to employed labour is 1/2. The government requires firms to pay pension contributions to the fiscal authority: the contribution is a small fraction x of the wage paid to each employed worker. Therefore, firms profits equal P y - W N - x W N and they are maximized taking the price level P, the nominal wage W, and the pension contribution rate x as given. Labour supply is given by: W = P b N where b is a positive constant. Answer all the following questions. a) Derive the labour demand schedule by solving the profit maximization problem of firms.
- Anna and Bob are the only residents of a small town. The town currently funds its fire department solely from the individual contributions of these two residents. Each of the two residents has a utility function over private goods ? and total number of firemen ?, of the form: ?(?,?)=2ln?+ln?. The total provision of firemen hired, ?, is the sum of the number hired by each of the two persons: ?=??+??. Ann and Bob both have income of 200 each, and the price of both the private good and a fireman is 1. They are limited to providing between 0 and 200 firemen. For the purposes of this problem, you can treat the number of firemen as a continuous variable (it could be man-years). Consider the setup from Question 2. Suppose that the government recruits additional ?N firemen and taxes Ann and Bob equally to cover the cost. Therefore, the total number of firemen is ??+??+?MA+MB+N, where ??,??MA,MB are appropriate individually-optimal contributions of ?A and ?B(i.e., the agents behave optimally,…Tatum is a mother of Anny (1 year old). Tatum derives utility from income Y (i.e. a disposable income that she can spend on consumption goods other than childcare) and leisure L according to the utility function U(Y,L)=Y*L . She has non-labour income of $300 per day. Her time endowment is 16 hours per day that can be spent either on Leisure (which mostly consists of caring for Anny) or labour market work. If Tatum works she has to leave Anny in the child care. Tatum’s wage is $30 per hour, while the childcare cost $5 per hour. Tatum only uses childcare when she works. Compute how many hours Tatum will work under these circumstances. Round your answer to the second decimal point.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?…
