A study by University of Minnesota economist, Joel Waldfogel, estimated the difference in the actual monetary value of gifts received and how much the recipients would have been willing to pay to buy them on their own. The study suggested that the average recipient's valuation was approximately 90% of the actual purchase price. a. In 2017, it was estimated that the average amount spent on winter holiday gifts in the United States was $906. Based on the estimate from the Waldfogel study, how much of this would be deadweight loss?

$90.6

What does this type of deadweight loss triangle reflect? -excess marginal costs and a lack of advantageous transactions -too many transactions executed and marginal benefits acquired -excess marginal costs and too many transactions -a lack of advantageous transactions implemented and marginal benefits acquired

-a lack of advantageous transactions implemented and marginal benefits acquired

When the forces of supply and demand lead to an inefficient outcome -economists call this a deadweight loss. -the economic surplus is maximized. -economists call this a market failure. -it is a signal that the government needs to take ownership of that market including all the resources involved.

-economists call this a market failure.

A study by University of Minnesota economist, Joel Waldfogel, estimated the difference in the actual monetary value of gifts received and how much the recipients would have been willing to pay to buy them on their own.

Suppose that Verania and Josimar are roommates that need to complete some household chores. Vacuuming and washing dishes need to be done. They know from the last time they did these chores that it takes Verania 2 hours to vacuum and 1 hour to wash dishes. It takes Josimar 3 hours to vacuum and 2 hours to wash dishes.

Because Verania is faster at both tasks, there is no benefit in each volunteer specializing in one task or the other. -is wrong. Because Verania has an absolute advantage in both tasks, she should perform both tasks herself. -is wrong. Because Verania has a comparative advantage in washing dishes, she should wash dishes, and Josimar should vacuum. -is wrong. Because Josimar has a comparative advantage in washing dishes, he should wash dishes, and Verania should vacuum.

Davis Florist has two employees, Anita and Jerome, and two tasks that need to be completed, floral arrangements and floral delivery. It takes Anita 30 minutes to finish one floral arrangement and 40 minutes to make a delivery. It takes Jerome 10 minutes to finish one floral arrangement and 30 minutes to make a delivery. Each worker works six hours per day. e. Suppose that, initially, both Jerome and Anita spend four hours each day doing floral arrangements and two hours each day doing deliveries. Now suppose they change their tasks, so that each individual does nothing but the task in which she or he has a comparative advantage. How many more floral arrangements and deliveries could they produce each day? ___________ additional floral arrangements and _______ additional deliveries

4, 2 It takes Jerome 10 minutes to finish a floral arrangement and 30 minutes to make a delivery. Therefore, if he devotes four hours to floral arrangements and two hours to deliveries, he will complete 24 floral arrangements and 4 deliveries in a six-hour day. It takes Anita 30 minutes to finish a floral arrangement and 40 minutes to make a delivery. Therefore, if she devotes four hours to floral arrangements and two hours to deliveries, she will complete 8 floral arrangements and 3 deliveries in a six-hour day. This adds up to 32 floral arrangements and 7 deliveries per day. If they allocate tasks based on comparative advantage, Jerome will make floral arrangements, and Anita will make deliveries. In a six-hour day, Jerome could complete 36 floral arrangements, and Anita could make 9 deliveries. Thus, if each individual specializes in the task in which she or he has a comparative advantage, the two together will complete 4 additional floral arrangements and 2 additional deliveries in a six-hour day.
