In early 2017, an article in the Financial Times about the oil market quoted the chief economist of oil company \(\mathrm{BP}\) as saying, "Pricing pressure is likely to come from the supply side, because of strong growth in US shale oil (crude oil found within shale formations), and the demand side as the rise of renewable energy, including electric vehicles, gradually slows growth in oil consumption." After reading this article, a student argues: "From this information, we would expect that the price of oil will fall, but we don't know whether the equilibrium quantity of oil will increase or decrease." Is the student's analysis correct? Illustrate your answer with a demand and supply graph.
[Related to Solved Problem 3.3 on page 88\(]\) In The Wealth of Nations, Adam Smith discussed what has come to be known as the "diamond and water paradox": Nothing is more useful than water: but it will purchase scarce anything; scarce anything can be had in exchange for it. A diamond, on the contrary, has scarce any value in use; but a very great quantity of other goods may frequently be had in exchange for it. Graph the market for diamonds and the market for water. Show how it is possible for the price of water to be much lower than the price of diamonds, even though the demand for water is much greater than the demand for diamonds.
Proposals have been made to increase government regulation of firms providing childcare services by, for instance, setting education requirements for childcare workers. Suppose that these regulations increase the quality of childcare and cause the demand for childcare services to increase. At the same time, assume that complying with the new government regulations increases the costs of firms providing childcare services. Draw a demand and supply graph to illustrate the effects of these changes in the market for childcare services. Briefly explain whether the total quantity of childcare services purchased will increase or decrease as a result of the regulations.
