Get started for freeIn 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.
State whether each of the following events will result in a movement along the demand curve for McDonald's Quarter Pounder hamburgers or whether it will cause the curve to shift. If the demand curve shifts, indicate whether it will shift to the left or to the right and draw a graph to illustrate the shift. a. The price of Burger King's Whopper hamburger declines. b. McDonald's distributes coupons for \(\$ 1.00\) off the purchase of a Quarter Pounder. c. Because of a shortage of potatoes, the price of French fries increases. d. McDonald's switches to using fresh, never-frozen beef patties in its Quarter Pounders. e. The U.S. economy enters a period of rapid growth in incomes.
What is the difference between a change in demand and a change in quantity demanded?
From 1979 to 2015 , China had a policy that allowed couples to have only one child. (Since 2016 , couples have been allowed to have two children.) The one- child policy caused a change in the demographics of China. Between 1980 and 2015 , the share of the population aged 14 and under decreased from 36 percent to 17 percent. And, as parents attempted to ensure that the lone child was a son, the number of male children relative to female children increased. Choose three goods and explain how the demand for them has been affected by China's one-child policy. Sources: World Bank, World Development Indicators, April 2016; and "China New 'Two Child' Policy Increases Births by 7.9 Percent, Government Says," cbsnews.com, January 23, 2017 .
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.
