Sylvan works full time at home, so only Alex works in the market. a) Given this information, which couple has the higher opportunity cost of home produced goods? Explain how you determined this. You can add a diagram if that helps, but you are not required to include one. b) Can you determine which couple has the higher utility? Explain why or why not. Suppose now that value of market production for both Alex and Esther increased to $12/per hour. c) Explain the change in the household joint production possibility frontier generated by this change. d) Explain what would happen to each couple’s choice of both household and market produced goods, using an analysis by means of income and substitution effects. e) What changes in time allocation for each couple that would be necessary to produce and consume this new bundle?

chases frozen turkeys at a constant wholesale price of $1/turkey, which is its full marginal cost for supplying turkeys. During July, only a small number of wealthy people are interested in buying turkeys in Pilgrim. Their demand curve is P = 10 – .02 Q, where P is Wegboys’ retail price for turkeys during the month and Q is the quantity of turkeys purchased. The demand curve for these wealthy people is constant – it is the same curve in both November and July. During November, a large number of less wealthy people enter the market to purchase turkeys for Thanksgiving. Their demand curve for Wegboys’ turkeys is P = 4 – .0005Q. In other months of the year, they do not purchase turkeys at any price. a. (5 points) What price should Wegboys charge in July to maximize its profits? Calculate its profits from turkey sales. b. (5 points) Demonstrate that Wegboys can earn a higher profit if it lowers its retail price for turkeys during November (you can do this without finding the optimal price). Explain the basic economic intuition.

m 2 After graduating from AUD, Salman plans to start a book publishing company in the Media City. He did some research and found that the printer will cost Dh 230,000. He estimated that the variable cost per book is Dh 170 and the selling price is Dh 390. a. How many books must he sell to break even? Also calculate the breakeven in dirham. b. In addition to the costs given above, if he wants to pay himself a salary of Dh 15,400 per year, what is her breakeven point in units and dirham? c. In the first three months of his business, he sold 400 books. Suddenly the printer breaks down. He spent Dh 25000 to fix the printer. In addition to 400 books sold, how many more books she should sell to breakeven? Assume that this part of the question is independent, and she does not draw any salary. Problem 8 A furniture store makes tables and chairs from plywood and glass. The store has 30 units of plywood, 24 units of glass. Each table requires 7 units of plywood three units of glass, whereas each chair requires three units of plywood and two units of glass. The demand for chairs is between 2 and 4. The ratio between the table and chair is at least 1 to 2. A table earns $225 in profit and a chair, $145. The store also wants a minimum profit of $5000. The store wants to determine the number of tables and chairs to make in order to maximize profit. Formulate a linear programming model for this problem

of $100 equals 20% . Included in the 20% margin is sales commission which equals 10% of the $100 , which is $10. If I decrease the commission to only 3% , $3 instead of the 10%, $10 , what will my new deal margin be? After we cut the commission on the deal , we are also going to reduce our price to the customer by 6% . What does the 6% represent in terms of overall dollars on the $100 service and what would the deal commission be after this additional change to the financial structure of the deal?

, a standard deviation of $1 would be considered large if it is describing the variability from store to store in the price of an ice cube tray. On the other hand, a standard deviation of $1 would be considered small if it is describing store-to-store variability in the price of a particular brand of freezer. A quantity designed to give a relative measure of variability is the coefficient of variation. Denoted by CV, the coefficient of variation expresses the standard deviation as a percentage of the mean. It is defined by the formula CV = 100(s/ x ). Consider two samples. Sample 1 gives the actual weight (in ounces) of the contents of cans of pet food labeled as having a net weight of 8 oz. Sample 2 gives the actual weight (in pounds) of the contents of bags of dry pet food labeled as having a net weight of 50 lb. There are weights for the two samples.

oking for an online math and SAT/ACT tutor, possibly an IB Math tutor as well.  My children are native English speakers, but go to an international school. They are looking to attend an English speaking school for the university.  Can you please let me know the price range I am expected to pay per hour? Also, I haven’t had some of the best experiences in the past with someone claiming that they could help with SAT only to find out that they weren’t qualified. At this point, I will need a way to demonstrate your expertise as an SAT or ACT tutor. Also, for IB Math, if you are able to do both.  I look forward to hearing from you. Just to let you know, I have other friends looking for a similar tutor. Please make sure to send your CV, and a personal statement if you have one, so I can better understand your teaching/tutoring philosophy better.  Oh yes, where are you located for time zone differences?  Best, Edward Rochman

To receive this special $60 price, the customer must buy a round-trip ticket. Ryan has a nonrefundable 30% penalty fare for cancellation; it estimates that about seven-tenths of 1% will cancel their reservations. The airline also estimates this special price will cause a passenger traffic increase from 350 to 700. Ryan expects revenue for the year to be 55.3% higher than the previous year. Last year, Ryan’s sales were $485,000. To receive the special rate, Janice Miller bought two round-trip tickets. On other airlines, Janice has paid $100 round trip (with no cancellation penalty). A.Calculate the percent passenger travel will increase. B.Calculate Janice’s loss if she cancels one round-trip flight. C.Approximately how many more cancellations can Ryan Airlines expect (after Janice’s cancellation)? (Round down your answer to nearest whole number.)

he efficacy of this spending is therefore relatively important. When it comes to contagious diseases, there are generally two strategies that can be adopted. The first involves prevention, which includes vaccinations to lower or eliminate the risk of contracting a disease. The second involves treatment of those unfortunate enough to get sick, treatment typically requires some form of a drug. Since pharmaceutical companies can produce both vaccines and drugs, we would like to understand the incentives they have to develop each type of medicine. To explore this question, consider a population of 100 consumers, 90 of whom have a low disease risk, say 10%. The remaining ten have a high risk – to make things simple, assume they are certain to contract the disease. In addition, suppose the disease generates personal harm equal to the loss of $100 for each individual when they are infected. Suppose also that pharmaceuticals of either form (vaccines or drugs) are costless to produce (once R & D has occurred) and are perfectly effective Question 2. What price would a profit maximising monopolist charge for a vaccine? What are the monopoly profits on the vaccine? What is the efficient outcome (i.e. SMB = SMC)? What is the welfare under the monopoly and at the efficient allocation? Question 3.Now consider the demand for the drug (assume that the vaccine is not available). Construct the demand function for the drug and plot it on a diagram. What price would a profit maximising monopolist charge for the drug? What are the monopoly profits from the drug? What is the efficient outcome? What is the welfare under the monopoly and at the efficient allocation? Question 4. If the R&D costs of the vaccine and drug are the same, what will the pharmaceutical company do? Explain your answer in terms of the variation in the willingness to pay and the size of the R& D costs. What would a social planner do? Question 5. What are the R&D cost for the vaccine and the R&D cost for the vaccine drug that would make a pharmaceutical company indifferent between developing the vaccine and the drug? Is the social planner indifferent in this case? Explain any difference.
