A question of ethics: Developing information system ethics

This study develops a pedagogy for the teaching of ethical principles in information systems (IS) classes, and reports on an empirical study that supports the efficacy of the approach. The proposed pedagogy involves having management information systems professors lead questioning and discussion on a list of ethical issues as part of their existing IS courses. The rationale for this pedagogy involves (1) the maturational aspects of ethics, and (2) the importance of repetition, challenge, and practice in developing a personal set of ethics. A study of IS ethics using a pre-post test design found that classes receiving such treatment significantly improved their performance on an IS ethics questionnaire. It appears to me that in Ethics, as in all other philosophical studies, the difficulties ... are mainly due to ... the attempt to answer questions, without first discovering precisely what question it is which you desire to answer.

Discussion of “Investor recognition and stock returns”

Lehavy and Sloan (2008, Review of Accounting Studies) note that prior studies find that earnings and cash flows explain only a small portion of the cross-sectional variation in stock return. This motivates them to investigate empirically the ability of a behavioral model of capital market equilibrium proposed by Merton (1987, Journal of Finance, 42, 483–510) to explain the remaining variation in stock returns. Their primary findings show that security value is, as predicted, increasing in investor recognition of the security and that investor recognition is incremental to and more important than cash flows in explaining the cross-sectional variation of stock returns. While the research question is intriguing and well motivated, a number of methodological limitations may limit the reliability of the findings/interpretations. In this paper, I first evaluate the motivation and potential contribution of the Lehavy and Sloan (2008) study. I then outline methodological limitations underlying the study and offer ways of overcoming them. In the final section, I state my conclusions.     

The Association of R&D and Capital Expenditures with Subsequent Earnings Variability

Abstract:  We estimate the association of investments in R&D and in physical assets (CAPEX) with subsequent earnings variability. We estimate these relations in different time periods and across industries. We find that R&D contributes to subsequent earnings variability more than CAPEX only in relative R&D-intensive industries – industries in which R&D is relatively more intensive than physical capital. In physical assets-intensive industries, we do not find similar relations. The findings suggest that with respect to subsequent earnings variability, fundamental differences between investment information about R&D and CAPEX exist. However, they are mainly noticeable in firms that operate in relatively R&D-intensive industries. The evidence also suggests there was a shift in the relations between R&D and CAPEX over time. Our findings contribute to the debate on accounting for R&D expenditures.     

ROBUSTNESS OF THE HEADQUARTERS‐CITY EFFECT ON STOCK RETURNS

Recent studies report that U.S. firms headquartered near each other experience positive comovement in their stock returns, a finding suggestive of local biases in equity trading activity. We investigate the robustness of these findings and find that including additional pricing factors in models for monthly stock returns materially reduces the magnitude of the headquarters‐city effect in stock returns. Additionally, we find that an implicit null hypothesis of zero local return comovement is inappropriate as there is positive comovement between a stock's return and returns on portfolios of stocks from nonheadquarters cities, on average. Nevertheless, results benchmarked against estimates based on resampling methods indicate a significant and robust headquarters‐city effect in stock returns.     

Organizational variables, sales force perceptions of readiness for change, learning, and performance among boundary-spanning teams: A conceptual framework and propositions for research

Sales organizations are continuously developing new ideas and approaches to be more competitive. One of the approaches taken by most successful organizations is the move from individuals to boundary-spanning, cross-functional teams. Sales teams are being employed to counter efforts by buying organizations to form buying centers. It is proffered in this paper that organizations that are ready for change are conducive to enhancement of sales team learning. Organization readiness for change is a condition impacted by a variety of organizational antecedent variables such as culture and climate. This paper proposes that sales team learning is impacted by team members' perceptions of the organization's readiness for change. In addition, we also posit the moderating influence of two environmental variables: turbulence and competitive intensity on the relationship between readiness for change and sales team learning. Sales team learning is then proposed to be related to a variety of sales outcomes. In this paper, we present a conceptual framework for understanding the contexts in which team learning occurs and the impact of team learning on team effectiveness. Throughout the paper, we present research propositions that provide opportunities for future examinations of team learning.     

Stimulating organic farming via publicly provided services and an auction-based subsidy

Governments generally use a mix of temporary hectare paymentsand provision of public services to stimulate the organic cropsector. In this paper, a conceptual model is developed for determininga socially optimal hectare payment for any given level of publicservices. Farm heterogeneity, due to the variability of soilquality and management skills, is explicitly taken into account.Using an nth price auction mechanism, farmers indicate whattheir reservation subsidy is for a given level of public inputprovision. The results of this auction are used to determinethe government's optimal policy choices.     

Interrelationships between environmental dependencies: A basis for tradeoffs to increase autonomy

General managers of large industrial plants in Israel were asked to evaluate the effects of environmental dependencies on their freedom of action. It was found that most segments of the environment were perceived as homogeneous—affecting the firms' autonomy in similar ways. Different components of government, however, were perceived as having conflicting interests both within the segment and with other segments of the environment. When a segment of the environment is heterogeneous, it is possible that managers use a tradeoff strategy, in which pressures generated by one component of the environment can be used as a means to reduce pressure of the other components.
