Two economists are attending a conference in an unfamiliar city. At the end of the day, Economist A states she is "in the mood for a high-quality dinner" and wanders through the center of the city looking for a restaurant. After narrowing her search to two fine-dining establishments located on the same block, she ultimately selects the restaurant with the higher prices (assuming cost is not an issue for either economist). Economist B chooses to go to a one-price all-you-can-eat buffet. Using economic theory how would you explain the difference in way Economist A goes about maximizing her utility compared to Economist B? Next year when they both return to the economics conference in the same city, which of the two restaurants do you think has a higher chance of not being there anymore?

our mother owns and runs art and craft store, and the business is doing well. She would have otherwise been employed as a high school geography teacher making $80,000 a year or as an interior decorator making $68,000 a year. She owns the building in which her shop is located, which she could have rented out for $24,000 a year. Her annual revenue from the shop is $430,000 and she employs four workers, each of whom earns $30,000 a year. On average, she spends $206,000 per year traveling, purchasing, and shipping unique merchandise for resale at her store. Based on this information, do you think you should encourage her to return to teaching? Explain your advice with the help of calculations on her opportunity costs, accounting profit, and economic profit.
