Suppose the representative consumer’s preferences are given by the utility function,

U(C, l) = aln C + (1- a) ln l

Where C is consumption and l is leisure, with a utility function that is increasing both the arguments and strictly quiescence, and twice differentiable.

Question:

The total quantity of time available to the consumer is h. The consumer earns w real wage from working in the market, receives endowment π from his/her parents, and pays the T lump-sum tax on the endowment. Setup the consumer’s optimization problem where he/she chooses C and l to maximize U(C, l). Obtain and interpret the optimization conditions and optimum consumption bundle for the consumer.

PS:

This is a constrained optimization problem.

There are two possible ways (that I am aware of); lagrangian and substitution to solve this.

Setup lagrangian, find first-order conditions and then solve for c and l.

A consumer likes two goods; good 1 and good 2. the consumer’s preferences are described the by the cobb-douglass utility function U = (c1,c2) = c1α,c21-α Where c1 denotes consumption of good 1, c2 denotes consumption of good 2, and parameter α lies between zero and one; 1>α>0. Let I denote consumer’s income, let p1 denotes the price of good 1, and p2 denotes the price of good 2. Then the consumer can be viewed as choosing c1 and c2...

3. Suppose that an individual’s utility function for consumption, C, and leisure, L, is given by U(C, L) = C 0.5L 0.5 This person is constrained by two equations: (1) an income constraint that shows how consumption can be financed, C = wH + V, where H is hours of work and V is nonlabor income; and (2) a total time constraint (T = 1) L + H = 1 Assume V = 0, then the expenditure-minimization problem is minimize...

1. Consider the representative consumer’s problem as follows. The representative consumer maximizes utility by choosing the amount of consumption good C and the amount of leisure l . The consumer has h units of time available for leisure l and for working Ns , that is, h = l+Ns . Government imposes a proportional tax on the consumer’s wage income. The consumer’s after-tax wage income is then (1−t )w(h −l ), where 0 < t < 1 is the tax...

Suppose a consumer’s Utility Function U(x,y) = X1/2Y1/2. The consumer wants to choose the bundle (x*, y*) that would maximize utility. Suppose Px = $5 and Py = $10 and the consumer has $500 to spend. Write the consumer’s budget constraint. Use the budget constraint to write Y in terms of X. Substitute Y from above into the utility function U(x,y) = X1/2Y1/2. To solve for the utility maximizing, taking the derivative of U from (b) with respect to X....

A representative consumer living in a Country A values consuming goods (C) and enjoys leisure (l). The consumer has h = 1 units of time to divide between working and enjoying leisure. For each hour worked, he receives w = 1.5 units of the consumption good. The consumer also owns shares in a factory which gives him an additional π = 0.55 units of income. The government in this economy taxes the consumer and uses the proceeds to buy consumption...
