The biotechnology industry and strategies of biodiversity conservation: The influence of managerial interpretations and risk propensity

This article presents the results of a questionnaire‐based mail survey which was conducted to examine the influence of managerial cognitions on the strategies for biodiversity conservation undertaken by individual companies in the North American biotechnology industry. The study confirmed that managerial issue interpretations and risk propensities were significant influences on organisational actions for biodiversity preservation. More specifically, the biodiversity conservation strategies undertaken by individual companies were influenced by whether or not the managers of these companies interpreted biodiversity conservation as an opportunity or a threat as well as the propensity of these managers to undertake risk on behalf of their companies. This article concludes that opportunity interpretations of biodiversity conservation by managers of biotechnology companies will be translated into proactive environmental responsiveness strategies in uncertain environments only if these managers also exhibit a high risk propensity.

Trend-following trading strategies in commodity futures: A re-examination

This paper examines the performance of trend-following trading strategies in commodity futures markets using a monthly dataset spanning 48 years and 28 markets. We find that all parameterizations of the dual moving average crossover and channel strategies that we implement yield positive mean excess returns net of transactions costs in at least 22 of the 28 markets. When we pool our results across markets, we show that all of the trading rules earn hugely significant positive returns that prevail over most subperiods of the data as well. These results are robust with respect to the set of commodities the trading rules are implemented with, distributional assumptions, data-mining adjustments and transactions costs, and help resolve divergent evidence in the extant literature regarding the performance of momentum and pure trend-following strategies that is otherwise difficult to explain.     

Mode of entry and ex-post performance

In this study I develop and empirically test hypotheses delineating how a set of industry- and firm-level factors are differentially associated with postentry performance of de novo and acquisitive entrants. First, I conceptualize structural entry barriers as sunk costs or irrecoverable investments that entrants must make in the entered industry to be competitive vis-à-vis incumbents. I then argue that de novo and acquisitive entrants differ in three important ways: (1) incremental vs. up-front sunk cost investments in overcoming impediments to entry; (2) increasing productive capacity vs. changing ownership in the entered industry; and (3) low vs. high costs of integration when realizing synergies with parent firms. I use the Trinet, FTC-ALB, and Compustat data bases to construct a sample comprising de novo and acquisitive entries made during the period 1980–82. Next, I evaluate postentry survival and growth between 1982 and 1986. Overall, empirical tests provided partial support for the hypotheses, and the explained variance in my models ranged from 17 percent to 37 percent. © 1998 John Wiley & Sons, Ltd.     

Learning to learn in the accounting Principles course: Outcome assessment of an integrative business analysis project

This paper reports on an effort to integrate some of the Accounting Education Change Commission's recommendations for the Principles course. A project involving comprehensive analysis of a publicly traded company was introduced in the Managerial Accounting course as a vehicle to develop critical thinking, problem solving, ethical sensitivity, team-work, and communication skills among sophomore-level business majors. As a means of assessing outcomes, a follow-up questionnaire was administered to measure the effectiveness of the project, and results were analyzed. The project was found to have made positive impacts across several dimensions of the learning process. Implications for Accounting curricula are discussed.     

Trends in corporate diversification

This paper studies the diversification and refocusing strategies of firms in the last three decades. The 1980s were characterized by a trend towards greater focus. This trend slackens in the 1990s to be replaced by a surge in the number of newly listed single-segment firms. From 2000 to 2007 there is very little change in the proportion of diversified firms. Overall, the proportion of conglomerates declines from 40% to 17% from 1980 to 1997. In addition, about one third of the diversifying firms reverse the diversification decision within four years. The analysis of the statements made by these firms suggests that there is significant heterogeneity in the motivations behind diversification.     

Scale variable specification in a money demand function for Malaysia

We investigate what scale variable is most appropriate in the money demand function for Malaysia. Candidates include income, consumption, disposable income, and domestic absorption and these are considered for simple sum M1 and M2 and for Divisia M1 and M2. Non-nested tests and other model selection criteria such as R² are used. The non-nested tests for the M1 aggregates are inconclusive but more support is given for income as the scale variable for the M2 aggregates, especially for Divisia M2. The other procedures also show that income is preferred for M2 and some support is also given for income for the M1 aggregates.     

Political Economy of Conditional Aid in a Federal Economy

This paper employs a political economy approach to model the joint determination of national and subnational sectoral protection in an open federal economy. Political interactions between special interest groups and policymakers as well as economic interrelationships between federal and state government policies are analyzed. The model is applied to study the effects of conditional financial assistance on policy‐making in the aid‐receiving federal economy. We find that policy‐based financial assistance to the federal government tends to reduce the extent of distortions resulting from the federal government policy. However, if federal and state government policies are strategic substitutes, state government induced policy distortions would increase, thereby detracting from the effectiveness of conditionality in reducing overall policy distortions in the recipient economy.
