Marketing-mix variables and the diffusion of successive generations of a technological innovation

Abstract: Research addressing the diffusion of successive generations of technological innovations has generally ignored the impact of marketing-mix variables. As a result, there have been several calls for the development of multiple-generation models that incorporate marketing-mix variables. The authors develop a model of first-time sales and subscriptions for successive generations of a technological innovation, which explicitly captures the effects of marketing-mix variables through a proportional hazards framework. The empirical analysis estimates the impact of price for two generations of cellular telephones in a European country. The results suggest that there are important substantive insights to be gained from the parameter estimates for this marketing-mix variable when intergenerational interdependencies are considered. For example, although the time path of the estimated price elasticities in a multiple-generation setting closely follows those reported previously for single generations, the auth...

Blockholders: A Survey of Theory and Evidence

Abstract: This paper reviews the theoretical and empirical literature on the role of blockholders (large shareholders) in corporate governance. We start with the underlying property rights of public corporations; we discuss how blockholders are critical in addressing free-rider problems and why, like owners of private property in general, blockholders are likely to be active in firm governance. We then examine what distinguishes a blockholder from an ordinary shareholder and advocate additional definitions from the typical threshold of 5% ownership. We next present new evidence on the frequency and characteristics of blockholders in United States corporations. Then we develop a simple unifying model to present theories of blockholder governance through both voice (direct intervention) and exit (selling one's shares). We survey the empirical evidence on blockholder governance, emphasizing the empirical challenges in identifying causal effects involving blockholders. We highlight the lack of credible instruments for blockholders and argue that exogenous variation should not be a prerequisite for research—a narrow focus on identification may lead to a focus on identifying narrow questions. We emphasize the value of descriptive research with blockholders and how endogeneity concerns can be addressed with economic logic and by directly testing alternative explanations. We close with suggestions for future research.

Conflict in Small Groups: The Meaning and Consequences of Process Conflict:

Abstract: Through three studies of interacting small groups, we aimed to better understand the meaning and consequences of process conflict. Study 1 was an exploratory analysis of qualitative data that helped us to identify the unique dimensions of process conflict to more clearly distinguish it from task and relationship conflict. Study 2 used a broader sampling of participants to (a) demonstrate why process conflict has been difficult to discriminate from task conflict in many conflict scales, and (b) develop a two-factor Process Conflict Scale that effectively distinguishes process from task conflict. Study 3 used this new scale to examine the relationship between process conflict and group viability (group performance, satisfaction, and effective group process). The results showed that process conflict negatively affects group performance, member satisfaction, and group coordination.

Insider Trading in Credit Derivatives

Abstract: Insider trading in the credit derivatives market has become a significant concern for regulators and participants. This paper attempts to quantify the problem. Using news reflected in the stock market as a benchmark for public information, we report evidence of significant incremental information revelation in the credit default swap (CDS) market under circumstances consistent with the use of non-public information by informed banks. Specifically, the information revelation occurs only for negative credit news and for entities that subsequently experience adverse shocks. Moreover the degree of advance information revelation increases with the number of banks that have lending/monitoring relations with a given firm, and this effect is robust to controls for non-informational trade. We find no evidence, however, that the degree of asymmetric information adversely affects prices or liquidity in either the equity or credit markets. If anything, with regard to liquidity, the reverse appears to be true.
