Assume that a city can earn an additional $100,000 of revenue each year from using drones to catch speeding drivers. What must the additional cost of using drones to catch speeders be to make this economically rational?

"Company A is willing to produce more generators if the price of a unit is $10,000 than if the price of a unit is $7,000." What is the microeconomics in this situation?

Three managers of the Magic Potion Company are discussing a possible increase in production. Each suggests a way to make this decision. HARRY: We should examine whether our company’s productivity—gallons of potion per worker—would rise or fall. RON: We should examine whether our average cost—cost per worker—would rise or fall. HERMIONE: We should examine whether the extra revenue from selling the additional potion would be greater or smaller than the extra costs. Who do you think is right? Why?

The English economist William Stanley Jevons described a world tour during the 1880s by a French singer, Mademoiselle Zélie. One stop on the tour was a theater in the Society Islands, part of French Polynesia in the South Pacific. She performed for her usual fee, which was one-third of the receipts. This turned out to be 3 pigs, 23 turkeys, 44 chickens, 5,000 coconuts, and "considerable quantities of bananas, lemons, and oranges.'' She estimated that all of this would have had a value in France of 4,000 francs. According to Jevons, "as Mademoiselle could not consume any considerable portion of the receipts herself, it became necessary in the meantime to feed the pigs and poultry with the fruit.'' Which of the functions of money does this payment fulfill? Which does it fail to fulfill? A complete answer will list the functions of money and evaluate each of them.

Michael owns a strawberry farm in central California and is deciding how many strawberries to supply this month. Which question appropriately applies the cost-benefit principle to the supply decision?   Is the price Michael gets for the extra bushel of strawberries at least as large as the marginal cost? What is the fixed cost of production for Michael's strawberries? If Michael was not producing strawberries, how else could he use his resources? Is Michael "holding all else constant" when making this decision?

Suppose that you got up early this morning to buy a concert ticket for your favorite band. You had to log in to their website and wait in a queue for 20 minutes to access the online sale, but you were ultimately successful in buying two tickets for $45 each. The show sold out minutes later. What is the true cost of attending the concert?

According to Thomas Friedman, Steve Jobs got his inspiration for the Mac from:

Your health club offers you “free” parking and unlimited use of its facilities seven days a week if you buy an annual membership for $3,650, to be paid at the time the membership is taken out. Otherwise, you buy daily passes for $10 per day for the use of the facilities, plus pay for your parking. Is your parking truly “free” if you buy the annual membership? Explain.  A newspaper report states that chocolate production is failing to keep up with worldwide consumption and could fall behind by 2 million metric tons annually by 2030. Does this create an excess demand or excess supply situation? Explain how it will affect the price of chocolates in the future.  The news report further goes on and states that adverse weather and fungal disease are partly to blame. Explain how that affects the supply curve.  How will your answer in b. above change if innovation of disease resistant and higher yielding cocoa trees replace their traditional counterparts?  Read the 2018 article…
