5.2 David N. gets $3 per week as an allowance to spend any way he pleases. Because he likes only peanut butter and jelly sandwiches, he spends the entire amount on peanut butter (at $0.05 per ounce) and jelly (at $0.10 per ounce). Bread is provided free of charge by a concerned neighbor. David is a particular eater and makes his sandwiches with exactly 1 ounce of jelly and 2 ounces of peanut butter. He is set in his ways and will never change these proportions. a. How much peanut butter and jelly will David buy with his $3 allowance in a week? b. Suppose the price of jelly were to increase to $0.15 an ounce. How much of each commodity would be bought? c. By how much should David's allowance be increased to compensate for the increase in the price of jelly in part (b)? d. Graph your results in parts (a) to (c). e. In what sense does this problem involve only a single commodity, peanut butter and jelly sandwiches? Graph the demand curve for this single commodity. f. Discuss the results of this problem in terms of the income and substitution effects involved in the demand for jelly.

The Energy Information Administration's forecast that world crude oil demand will likely outpace supply by 20 million barrels this year has also increased market uncertainty and driven up prices. Companies in the US steel and alumina industries have been urging the loosening of import restrictions because they fear running short of petrol. Despite the potential market effects, analysts believe that most steel and alumina companies won't be significantly impacted because crude oil only accounts for a small fraction of their overall costs. In general, rising crude oil prices are the result of a mix of supply and demand issues, market uncertainty, and other reasons. The price of this significant commodity will undoubtedly continue to be significantly influenced by global supply and demand dynamics, even though the precise trajectory of prices in the future is difficult to forecast. 1) Draw a graph to show this information.
A computer reseller needs to decide how many laptops to order next month. The lowest end laptop costs $220 and the retailer can sell these for $300. However, the laptop manufacturer already announced that they are coming out with a new model in a couple of months. Any laptops that will not be sold by the end of next month will have to be heavily discounted at half-price. The reseller also needs to consider that every time he fails to fulfill a laptop order, he stands to lose $25 for every unit. Based on the past months’ sales, the reseller estimates the demand probabilities for sales (S) as follows: P(0 units) = 0.3; P(1 units) = 0.4; P(2 units) = 0.2; P(3 units) =0.1. The reseller thinks it’s a good idea to conduct a survey on whether or not his customers are going to buy laptops and how many. The survey results will either be Yes (Y), No (N) or Don’t Know (DK). The probability estimates of the results based on the demand for number of units are: P(Y|S = 0 units) = 0.1 P(Y|S = 1…

Suppose you are interested in studying the effect of time spent in an SAT preparation course on actual SAT score. You propose the following regression of SAT score on hours spent in preparation for SAT and family income: Y = Bo + BiX + B2X2 + u Where Y = score on SAT X₁ = time spent in studying in an SAT preparation course X₂ = income of the student's family u = error term An important assumption in the regression model with two independent variables is that E(u|x₁,x₂)=0. Assume for simplicity that the only other relevant factor (contained in the error term) that affects Y is natural ability. That is, natural ability and u are essentially equivalent in your regression. In the context of your proposed regression, this assumption assumes which of the following?
