Economic analysis of gift giving

John is trying to decide how to divide his time between his job as a stocker in the local grocery store, which pays $7/hr for as many hours as he chooses to work, and cleaning windows for the businesses in downtown. He makes $2 for every window he cleans. John is indifferent between the two tasks, and the number of windows he can clean depends on how many hours he cleans a day, as shown in the table below: Cleaning time (hr/day) Total numbers of windows cleaned 0 0 1 7 2345 11 14 16 17 What is John's per-window reservation price to justify the 4th and 5th hours of cleaning windows? A. $7 and $7.5 respectively B. $2 and $3.5 respectively C. $3.5 and $7 respectively D. $11 and $14 respectively

Assume you are pursuing a bachelor’s degree and you have 40 hours to divide between work and school in a week. You choose the amount of time you spend on each based on the classes you take and the hours you request at work. The degree will take you 3 years to complete if you dedicate 40 hours a week and do not take summers off. Obviously, if you devote no time to school, you never get your degree. You have been going to school full time for two quarters.  In the third quarter, you do not receive as much loan money as you anticipate and need. You decide to work 20 hours a week to make up the difference and take fewer classes. What is your opportunity cost? Make sure to include how this change will factor into the length of time it will take you to finish your degree.

Task 4: leisure or work? The consumer choice is not restricted to the choice of consumption goods. In fact, it can apply to all our decisions that involve trade-offs. Suppose Mary has a wage per hour of 10 euros. With her earned income she consumes. That is, C = wH per day. She also decides how many hours to work of take leisure time each day. H = 24 – N, where H is work and N is leisure. Her utility is given by C1-o U(C, N) + B log(N) 1- o (a) Solve for the optimal decision of labor/leisure. Plot the budget constraint and the indif- ferent curve. What is the labor supply function? (b) If o > 1, what is the shape of the labor supply? How does it relate with the income and

Your Econ. Professor bought airline tickets to leave a conference early on Saturday morning. He later found out that he needed to present a paper later that Saturday, so he changed his tickets at a cost of $200. When he got to the conference, he discovered that he was scheduled twice: on Friday and on Saturday. He was given his choice of when to give the presentation. He said he would present on Saturday, because he paid an extra $200 in order to stay. Explain why you agree or disagree with his logic.

Your business produces two products: graphics and writing assessments. However, time is finite and your business must allocate its time between the two products. If your business is producing one service, it cannot produce the other service at the same time. Based on previous experience, you know that your firm can produce 11 graphics and 20 assessments per day. Your firm could also produce 7 graphics and 40 assessments per day. Given these production possibilities, what is the tradeoff between your two services? Make sure you estimate your tradeoff (opportunity cost) in terms of how much you receive for each unit of graphics services that you give up, that is, for 1 unit of graphics given up, how many units of assessments do you gain? Make sure to express your answer to the first decimal point.

The Chief Executive Officer of Dar Al Herfya (World of Handicrafts) spends her days contacting potential clients and setting up meetings in which she explains the salient features of the hand-made products she sells and their role in sustaining the rural economy in Oman. Her hectic schedule has not diminished her enthusiasm a bit. “This has been my routine for the last three years. You have to work hard if you have a mission,” says Zuwaina of her pet project. In 2012, Zuwaina relinquished her top corporate job, and all the perks that went with it, to launch her own company with the goal of promoting traditional Omani handicraft. “I worked with Omran as director of branding, and Omantel as senior manager of branding and communication.

It culminated in the launch of Dar Al Herfya,”…
