Chez has the following preferences over toothpaste, T, and a composite good, G, that represents all other goods. H (G, T ) = 100 × ln(T ) + G Chez receives $500 per month in income. The price of a tube of toothpaste, PT , is one dollar per tube and the price of the composite good is $.01 per unit of the composite good. (a) Determine the marginal utility of additional tube of toothpaste, the marginal utility of an additional unit of the composite good, and the rate at which Chez is willing to exchange toothpaste for the composite good?
Given H(G,T)=100*ln(T)+G
Marginal utility of additional tube of toothpaste=dH(G,T)/dT=MUT=100/T
Marginal utility of additional unit of composite good=dH(G,T)/dG=MUG=1
Rate at which Chez is willing to exchange toothpaste for composite good=MUG/MUT=T/100

4. Devon's preferences over food and a composite good are given by u(x, y) = xy , where x is the quantity of food and y is the quantity of composite good. His income is $120 per week. a) Find Devon's optimal bundle when the price of food is $4 per unit. b) Calculate Devon's income and substitution effects of a decrease in the price of food to $2 per unit.
Consider a representative consumer who has preferences over an aggregate consumption good c and leisure l. Her preferences are described by the utility function: U(c,l) = ln(c) + ln(l) The consumer has a time endowment of h hours which can be used to work at the market or enjoyed as leisure. The real wage rate is w per hour. The worker pays a proportional wage tax of rate t, so the worker’s after-tax wage is (1−t)w. The consumer also has...
T/F/U. Imagine that two goods make you happy: Good A and good B. The marginal utility of good A is 10 at a price of $2 per unit and the marginal utility of good B is 5 at a price of $1per unit. To satisfy the optimal consumption rule, you would want twice as many of good B than good A. Show your work and tell me how you arrived at your answer using the definition of optimal consumption.
John has the following utility function that represents his preferences over food (x) and housing (y) (his only two expenses) and marginal utilities: มุ4 for a level of wealth W and prices of food and housing P y respectively. Using the results from the previous homework answer the following questions Write down the Engel Curve for both goods and graph them 2) Assume W-10 and the price of food changes from 1 to 3 while the price of housing remains...

Problem 2. Consider a consumer has Cobb-Douglas preferences over two goods 21 and 22, given by u (21, 22) = 7 ln 21 + In 22. Let pı = 5 and p2 = 3 be the prices of the two goods, and suppose the agent has income I = 20. Suppose there is rationing of goods, so that in addition to paying for goods, the agent must have the appropriate number of coupons. Suppose, the agent begins...
1. Which of the following statements best describes the law of diminishing marginal utility? Consumers will purchase more of a good at a lower price, ceteris paribus. Consumers maximize total utility when the marginal utility per dollar spent is equal for all goods consumed. Each successive unit of a good consumed yields less additional utility. Consumers behave rationally when the price of a good equals the marginal utility of the good. 2. Assume the price elasticity of demand for Nike...
