A change in market responses to the environmental management ranking in Japan

This article investigates stock price reactions to the release of the environmental management ranking issued by Nihon Keizai Shimbun (Nikkei newspaper) from 1998 to 2005, by using a standard event study methodology. An examination of stock price movements of the top 100 manufacturing companies reveals that stock prices during the sample period did not respond significantly to the release of the ranking within a 3-day event window. However, market responses became significantly positive after 2003, while they were significantly negative in 1999 and 2000. The stock prices of upgraded companies in particular reacted negatively before 2000, but positively after 2002. These results indicate that market reactions were changed between 2001 and 2002, when the Japanese government showed its strong commitment to environmental policies by establishing the Ministry of the Environment and signing the Kyoto Protocol, following a number of legislations.

Quality Competition and Social Welfare in Markets with Partial Coverage: New Results*

We use a vertical product differentiation model under partial market coverage to study the social welfare optimum and duopoly equilibrium when convex costs of quality provision are either fixed or variable in terms of production. We show the following new results. First, under fixed costs, the social planner charges a uniform price for the single variant that just covers costs of quality provision. Like the duopoly equilibrium, this socially optimal pricing entails a partially uncovered market, but a smaller share of the market is served compared with the duopoly equilibrium. Second, for the variable cost case, it is socially optimal to provide both high‐ and low‐quality variants, but market shares need not be equal. This differs from the result in fully covered markets. Third, in the duopoly equilibrium, the quality spread is too wide under variable costs relative to the social optimum. Under fixed costs, the duopoly produces two variants, but quality is too low relative to the social optimum, which has only one variant.
