The demand for personal computers has been estimated to be Q = 500,000 - 700P +200I - 500S. Assume that per capita income I is $13,000 and the average price of software S is $400. When the price of personal computers is P=$3000,
The new mayor has pledged to reduce air pollution, and the only source of air pollution in the city are two cement plants, plant A and plant B. 25 years ago, when plant A was constructed, the cement production techn..
The total number of movie projections, M, is the sum of the number paid for by each of the two persons: M = MS + ML. Spielberg and Lucas both have income of 70, and the price of both the private good and a movie projection is 1. They are limited, ..
The agency of Labor Statistics follows 5-steps to calculate Consumer Price Index. Determine three strengths and three weaknesses of the Consumer Price Index calculation.
What is the probability that the annual return in a given year will exceed 15%? Suppose that the fund managers change the holdings of the fund such that the mean becomes 15% and the standard deviation becomes 5%. What are the new values for the pre..
Find (all) the partial derivatives (e.g. ?u/?x and ?u/?y) of the following functions: 1. Q(p,I) = 300 - 3p - 4I 2. u(x,y) = 10xy 3. u(x,y) = ax? y? 4. z = (x+y)2 5. z = 2x3-11x2y +3y2
Jim's utility function is U(x, y) = xy. Jerry's utility function is U(x, y) = 1,000xy + 2,000. Tammy's utility function is U(x, y) = xy(1 - xy). Oral's utility function is U(x,y)= -1/(10+2xy).Marjoe's utility function is U(x, y) = x(y + 1,000). Pa..
Describe the effect of this change in units on the estimated regression coefficients and their standard errors, t and F-statistics, p-values, and the value of R 2 .
On the basis of the information regarding the risk involved in the two projects, you come up with the following probability distributions for the projects:
Spookmart and Scaretown are the only two halloween costume stores in town. Both the stores are wondering how many Miley Cyrus twerking costumes to order. Each costume costs $2 from the supplier (i.e., marginal cost for the stores is $2) and market..
Suppose per unit tax, T is imposed on buyers. Then what is the equilibrium quantity and equilibrium price? Now, assume T=30, then what will be equilibrium price and quantity. (Hint: use P is the price producer receives, and P+T is price paid by th..
Imagine that the current price of waste disposal is $0.025/lb and the average waste disposal is 2.40 lb/p/d. When the price was previously $0.01/lb, the average waste disposal was 2.52 lb/p/d. Assume that the marginal social cost of waste disposal..
