A comsumer has the utility function U(x,y)=e^( (y+√x) ^ 1/3 ) where x is the good in concern and y is the money that can be spent on all other goods(so the price of y is normalized to be 1). The income of this consumer is 100.
(a)(10 pts)Derive the demand function of x for this consumer.
(b)(5 pts)Calculate the price elasticity of the demand function in (a). Is it true that the absolute value if the elasticity of the demand decreases as the amount of x increases?
(c)(10 pts)Suppose price if x decreases from 1/2 to 1/4. Calculate the compensating variation of this price change.

Consumer's surplus: A consumer has the utility function U(x,y) =e^((ln(X)+Y)^1/3) where X is the good in concern and Y is the money that can be spent on all other goods. (So the price of Y is normalized to be 1). The income of this consumer is 100. (a) (10pts) Derive the demand function of x for this consumer. Make sure that at every price of x, the consumer always has enough income to buy the amount of x as indicated...

Anna's utility function is given by U (r.y) = (r + 3) (y + 2), where I and y are the two goods she consumes. The price of good r is p ,. The price of good y is Py. Her income is m. (a) Write her maximization problem and find her demand functions for the two goods. Is it always possible to have an interior solution? Justify your answer. (b) Are the two goods ordinary or giffen? Are the...
Consider two goods, good 1 and good 2. The consumer’s utility function is given by U(x1,x2)=V(x1)+x2. Derive the ordinary demand function of good 1. When the market price of good 1 is given P1=P1' , derive the consumer’s surplus. If the price is changed to P1=P1", prove that the change measured by consumer’s surplus is the same as the Compensating variation. Also prove that it is the same as Equivalent variation.
Consider a consumer whose utility function is given by U(x, y) = x^1/4y^1/2, where x and y represent quantities of consumption of two consumer goods. (a) Derive and interpret the consumer’s Marshallian demand functions for x and y. (b) Derive and interpret the consumer’s Indirect Utility Function. (c) If the consumer’s income is $1000 and the prices of x and y are both $5, how should the consumer maximize her utility? What is her maximum level of utility? (d) Suppose...
A consumer buys two goods, good X and a composite good Y. The utility function is given as U(X,Y) = In3XY. The price of X is Py, the price of Y is Py and Income is I. 1) Derive the demand equation for good X. ( 5 marks) 2) Are the two goods X and Y complements or substitutes? Why? ( 5 marks) 3) Suppose that I=$10 and suppose that initially the Px = $1 and subsequently Px falls and...
A consumer has preferences represented by the utility function u(x, y) -xlyi. (This means that a. What is the marginal rate of substitution? b. Suppose that the price of good x is 2, and the price of good y is 1. The consumer's income is 20. What is the optimal quantity of x and y the consumer will choose? c. Suppose the price of good x decreases to 1. The price of good y and the consumer's income are unchanged....
Suppose a consumer's preferences can be represented by the utility function: U(X,Y)=X3/5Y1/4 a. Derive the function for the marginal rate of substitution holding utility constant: U X Y b. Derive the demand curves for the two goods, X and Y. c. Confirm that both demand curves slope downward. d. Calculate the price elasticity for each of the goods. e. Calculate the income elasticity for each of the goods.
1. When a consumer has a Cobb-Douglas utility function given by u(x, y) = xa yb , their demand for good x is given by x∗ = m/Px (a/a+b) where m is income and Px is the price of good x. Using this demand function, find the formula for this consumer’s price elasticity of demand. Interpret it in words.
