If x 1 and x 2 are the number of items of two goods bought, a customer’s utility is U ( x 1 , x 2 ) = 2 x 1 x 2 + 3 x 1 . The unit cost is $ 1 for the first good and $ 3 for the second. Use Lagrange multipliers to find the maximum value of U if the consumer’s disposable income is $ 100 . Estimate the change in optimal utility if the consumer's disposable income increases by $ 8 .

1. Identify the last two items (consumer goods and durable goods) you purchased. Alternatively, select any two items you purchased during the last two months. Choose diverse items and analyze each item in terms of the following factors: a. Why did you buy that item? How did you decide what to get? b. What attributes proved most important in narrowing your choices? c. Where did you get your information about the item? d. Where did you go to buy the...

Suppose that x is real number. Prove that x+1/x =2 if and only if x=1. Prove that there does not exist a smallest positive real number. Is the result still true if we replace ”real number” with ”integer”? Suppose that x is a real number. Use either proof by contrapositive or proof by contradiction to show that x3 + 5x = 0 implies that x = 0.

Suppose there are two goods in an economy, X and Y. Prices of these goods are Px and Py, respectively. The income of the only agent (consumer) in the economy is I. Using this information, answer the following questions: a. Write down the budget constraint of the consumer. Draw it on a graph and label the critical points accordingly. Provide a verbal explanation of why all income is spent, mentioning the underlying assumption for this outcome. b. Define substitution and...

Two goods are given, where x1 and x2 are the number of units of these goods. The preference structure of a consumer is given by the following (ordinal) utility function: u (x1, x2) = x1 * x2 The indifference curves show a strictly convex course to the origin. The prices of the goods are given by p1 and p2. The consumer wants to achieve the level of utility ū with minimal expenditure. Determine the Hick’s demand function Please specify the...

Goods 1 and 2 are perfect complements for Kane. He always consumes these two goods in the ratio of 2 units of good 2 for every unit of good 1. The price of good 1 is $1.00, and the price of good 2 is $4.00. Kane has $936.00 to spend. part 1) The substitution effect of a change in the price of good 2 from $4.00 to $6.00 will reduce the demand for good 2 by _______ units. part 2)...
