New Pedagogy and New Content: The Case of Statistics

Abstract: Summary Statistical education now takes place in a new social context. It is influenced by a movement to reform the teaching of the mathematical sciences in general. At the same time, the changing nature of our discipline demands revised content for introductory instruction, and technology strongly influences both what we teach and how we teach. The case for substantial change in statistics instruction is built on strong synergies between content, pedagogy, and technology. Statisticians who teach beginners should become more familiar with research on teaching and learning and with changes in educational technology. The spirit of contemporary introductions to statistics should be very different from the traditional emphasis on lectures and on probability and inference.

Selling to Socially Responsible Consumers: Competition and The Private Provision of Public Goods

Abstract: We model firms as competing for socially responsible consumers by linking the provision of a public good (environmentally friendly or socially responsible activities) to sales of their private goods. In many cases, too little of the public good is provided, but under certain conditions, competition leads to excessive provision. Further, there is generally a trade-off between more efficient provision of the private and the public good. Our results indicate that the level of private provision of the public good varies inversely with the competitiveness of the private-good market and that the types of public goods provided are biased toward those for which consumers have high participation value.

Strategic Group Formation and Performance: The Case of the U.S. Pharmaceutical Industry, 1963-1982

Abstract: The focus of this paper is on three major questions: 1 what is the theoretical rationale for the strategic group concept?; 2 does strategic group membership have performance implications?; and 3 are strategic groups and membership in strategic groups stable characteristics of industries? A statistical procedure is proposed to longitudinally identify strategic groups. The empirical setting is the U.S. pharmaceutical industry over the period 1963-82. While performance differences are found in terms of market share, profitability differences between groups are not observed. Neither are differences found in terms of risk and risk-adjusted performance. These results are attributed to the existence of performance variation within each strategic group. A dynamic model of competitive repositioning is proposed which helps integrate the findings from the study.
