Problem
In each of the following examples, discuss wich market model appears to best explain the behavior described (Perfect competition, Monopolistic compeition, Oligopoly, Monopoly):
a. Corn prices reached highs in United States in August 2012, given the worst drought in decades. However, by October these prices started to drop again as countries including China, Japan, and South Korea began to purchase from producers in other countries such as Argentina and Brazil.
b. In 2012, Staples Inc., Office Max Inc., and Office Depot Inc. were all closing many stores, decreasing the size of their stores, and focusing more on online operations. All three chains struggled to deal with changing consumer shopping habits as consumers tested equipment in the stores and then made purchases online.
c. In fall 2012, T-Mobile announced it was close to a merger with its smallest rival MetroPCS. This merger would strengthen T-Mobile's position as the forth-largest wireless operator in the United States. The merger would allow the combined company to cut costs and operate on a larger scale.
d. Chinese cooking is the most popular food in America that isn't dominated by big national chains. Chinese food is typically cooked in a wok that requires high heat and a special stove. Specialized chefs are also required. Small mom-and-pop restaurants comprise nearly all of the nation's 36,000 Chinese restaurants, which have more locations than McDonald's, Burger King, and Wendy's combined.
