The behavior of the macro or mass-production segment of the U.S. brewing industry appears to be paradoxical. Since the end of Prohibition in 1934, the number of independent brewers has continuously declined while the major national brewers, such as Anheuser-Busch, Miller, and Coors, have gained market share. In spite of this decline in the number of competitors, profits and market power have remained low in brewing. Iwasaki et al. (2008) explain this result by providing evidence that changes in marketing and production technologies favored larger brewers and forced the industry into a war of attrition, in which only a handful of firms could survive. This led to fierce competition, especially from the 1960s through the mid 1980s. Since the late 1990s, the war appears to have subsided. Thus, the purpose of this study is to determine whether price competition diminished after the mid-1990s. We find evidence that competition has diminished but not enough to substantially increase market power. (JEL Classification: D22, L11, L66)

a b s t r a c tWe analyze the effect of Toyota's faulty accelerator pedal on stockholder wealth. Using the event study methodology, we show that a major recall in January of 2010 is associated with a 19% fall in the company's cumulative abnormal returns. Continued concerns that Toyota was unable to identify and adequately fix the problem prompted the National Highway Traffic Safety Administration to conduct its own investigation in March, 2010. The results of this government investigation exonerated the company and Toyota's cumulative abnormal returns rose by almost 9%. The Toyota case provides an opportunity to study a product recall with both company error and a government action that addressed concerns about the safety of the product.
