Q7: An individual lives for only two periods and has preferences given by the follow-ing intertemporal utility function:U = lng + aln(1-h₁) + B[lno₂+ a ln(1 — h₂)](1)where, c₁, c₂ denotes consumption in period 1 and period 2 respectively h₁, h₂ denotethe labour supply in period 1 and 2 respectively. Therefore 1-h is the amount ofleisure time in period 1.The term 3 is the discount factor. The problem of the individual at period 1 is tochoose consumption in both periods and labour supply in both periods subject tothe following budget constraints:+8= why and 0₂= w₂h₂ + (1+r)swhere s denote the saving, w denotes the wates and r denotes the real interest rate.(a) Provide an economic interpretation of the two budget constraints written above.(b) Combine the two budget constraints written above and prove the economicinterpretation of of life time budget constraint.(c) Set the Lagrangean function and find the first order conditions with respect toC₁ C₂, hi and h₂.(d) Find the Euler equation of consumption and explain what happens to therelative consumption when there is an increase in interest rate.

The objective of the question is to understand the economic interpretation of the budget…

Susan obtains utility by consuming carrots C and enjoying leisure L. Suppose that she has a daily non-wage income Y of £100 and is paid a fixed hourly wage rate of £10 for every hour she works in a local coffee shop. Assume that Susan is a utility maximiser and is free to choose x hours of work per day where 0 ≤ x ≤ 10. Assume also that the unit price of C is £1. a) Suppose that L is measured on the horizontal axis and C on the vertical axis. Use these axes to draw the set of all C and L combinations that Susan can choose from. Write down Susan’s budget equation. b) Suppose that Susan’s preferences over carrots and leisure are expressed by the following utility function: U(C,L) = min{C, 10L}. Calculate Susan’s optimal consumption bundle, both algebraically and graphically. Calculate the value of MRS at the optimal choice. c) Suppose instead that Susan’s preferences are such that indifference curves in the L-C space are strictly convex to the origin, and that she chooses to work 5…

a) Present the Lagrangian (constrained maximisation) problem for the household under this modified specification and derive the first order conditions in this case. Hint: the household chooses c1, c2, ℓ1 and ℓ2. b) Use the first order conditions for ℓ1 and ℓ2 to derive an expression for the relative amount of leisure time chosen by the household over the two periods, i.e. derive an expression for (1–ℓ1)/(1–ℓ2). Explain how an increase in the relative wage (w2/w1) affects the household’s decision about how much leisure to enjoy in each period. c) Calculate the intertemporal elasticity of substitution between period 1 and period 2 leisure time in this case. Explain how the magnitude of this elasticity influences the household’s decision-making in the model. d) Use the first order conditions for c1 and c2 to derive an expression for the relative amount of consumption chosen by the household over the two time periods, i.e. derive an expression for c2/c1.

11. A worker derives utility from consumption, C and leisure, L U = U(C, L) and initially faces the constraints p.C = N+w.H H = 24 - L where p is the nominal price of consumption, N> 0 is unearned income, w is the nominal wage and H is hours worked. (a) Derive the budget constraint in terms of C and L and show on a diagram an initial optimal choice of C and L, in which both are positive. (b) State this equilibrium algebraically, and briefly explain how it can be derived. (c) Show that, assuming normality of leisure, for some value N*, if N> N*, the individual will choose not to work. Is the initial level of N in your answers to parts a) and b) greater or less than N*?
just answer the part e notice that you can do part e without the answer of abcd.
Consider a worker who consumes one good and has a preference for leisure. She maximizes the utility function u(x, L) = xL, where a represents consumption of the good and L represents leisure. Suppose that this worker can choose any L € [0, 1], and receives income w(1 – L); w represents the wage rate. Let p denote the price of the consumption good. In addition to her wage income, the worker also has a fixed income of y ≥ 0. (a) Write down the utility maximization problem for this consumer. Solution: The problem is max x L s.t. px ≤w(1 L) + y. x>0, LE [0,1] The budget constraint may also be written with equality since preferences are monotone. (b) Find the Marshallian demands for the consumption good and leisure. Solution: Using FOCs will find the maximum since preferences are Cobb-Douglas (and therefore convex). Dividing the FOCs L= Xp and x = Xw gives wL = px. Substituting into the budget constraint and checking the restriction L = [0, 1], we get and x(p, w, y) L(p, w, y) = = = 1 w+y…
Answer please with added diagrams b) Assume that your optimal choice of consumption and leisure is to work 8 hours per day. Illustrate this choice diagrammatically using the feasible set and indifference curves. c) Use indifference curves and the feasible set to show why, given the properties of the optimal choice in part b it is not optimal to work, say, 10, or 6 hours per day.
Fred is planning his consumption over two time periods. Fred's preferences for consumption in period and two can be represented by the following utility function: U(c,,c,) = C +(1+p) C" , where pis the subjective discount rate, and c;,c, is consumption in the first and second period. Fred's income in the first period is y, and grows by g % from the first period to the second period. Fred has access to perfect financial markets. The rate of interest is r>0. (a) Derive Fred's demand functions for consumption in the two periods as functions of p,r , y and g. (b) Derive Fred's demand for borrowing/saving as a function of p,r, y and g. (c) Give a condition involving the relationship between r and g for when Fred will borrow and when he will save.
