This paper estimates the effects of actual and potential rivalry on profitability of firms in the U.S. pharmaceutical industry during the 20‐year period 1963–82. The results show that during the 1960s actual rivalry among the sampled firms did not materially affect firm profitability, but that during the 1970s competition among incumbents had an increasingly adverse effect on their profitability. The results also show that potential competition significantly reduced drug firms’ profitability during the entire 20‐year period. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

ABSTRACTIn this study, we examined the relationship between organizational complexity and the adoption of participatory innovation in German municipal government. We proposed that organizations with more complex organizational structures are more likely to adopt participatory innovation. We investigated municipalities (N = 394) of the German state of North Rhine-Westphalia and used participatory budgeting as an indicator for innovation. Our results indicate that organizational complexity expressed by functional differentiation has a positive relationship with the occurrence of participatory innovation. The results inform a debate about the value trade-offs that are inherent to the structural design of public organizations. 相似文献

Je mehr individuelle Leistungen die Kunden verlangen, desto mehr Informationen ben?tigen die Anbieter. W?hrend die H?ndler
im Distanzgesch?ft über personalisierte Daten ihrer Kunden und vor allem im Online-Shop über Bewegungsdaten verfügen, hat
der station?re Einzelhandel noch erhebliche Datenlücken. Diese Lücken kann man mit einer Pervasive-Computing-Umgebung schlie?en.

Common reasons mentioned for a firm's internationalization are related to advantages for the firm. However, if firms are conceptualized as political coalitions, this view does not seem to be sufficient to explain why and to what extent firms internationalize. A principal-agent theoretical approach focusing the ownership-stake-related motivations and bargaining power of owners plus the range of actions managers can employ in different ownership situations offers an alternative explanation. We consequently studied the influences of ownership structure – defined as the concentration of ownership – on a firm's degree of internationalization and the main regions of international diversification. Overall, we conclude that the relationship is non-linear. To test our hypotheses, we utilize panel data for the 102 largest German manufacturing firms from 1990 to 2006. The analysis confirms our assumptions. 相似文献

Many employees in today’s organizations are involved in more than one team at the same time. Building on the challenge-hindrance stressor framework, this study investigates potential benefits and disadvantages of such multiple team membership (MTM) for individual employees. Furthermore, we extend this framework with insights from the job demands-resources model to propose that, depending on an employee’s organizational tenure, individual MTM will differentially shape his or her perceptions of work challenge and role ambiguity, subsequently influencing the employee’s job performance and absenteeism. We tested our conceptual model using time-lagged multi-source data from a large organization of applied research (N = 1211). Our results demonstrate that, for employees with relatively low organizational tenure, MTM was negatively associated with perceived work challenge and positively associated with perceived role ambiguity, which in turn associated with lower job performance and higher absenteeism. For employees with higher organizational tenure, by contrast, MTM associated positively with their work challenge perceptions and subsequent performance outcomes, whereas MTM was unrelated to perceived role ambiguity as well as absenteeism. These findings identify relevant psychological mechanisms and a key contingency factor that explain when and why MTM may have positive or negative individual-level consequences. 相似文献

How many resources does a nation spend on transactions costs to ‘grease the wheels of trade’? To examine this question the Dutch economy is used as a case study. The Netherlands are known as a nation of traders and this image was derived in the seventeenth century from successes in long distance trade, shipping and financial innovations. Despite its historical background the trading sector has never been adequately measured. In this paper, we present a first attempt in measuring and describing the Dutch transaction sector. Measurement by means of occupational data points out that approximately 25% of Dutch workers is employed in transaction jobs, and 29% if one includes transport tasks. We make the case that traditional industrial sector categories overestimate the true transaction character of an economy. Traditional ‘trade’ sectors employed 13% of the workers in 1807 and 39 percent in 1998, but these figures conceal the fact that all organizations employ jobs which have transformation and transaction tasks. A counterfactual exercise suggests that the growth of the transaction sector share in employment over two centuries was not 200% but 42%. 相似文献

Robust planning: a new paradigm for demand chain planning 总被引:3,自引:0,他引:3
This paper proposes a new paradigm for tactical demand chain planning (DCP), called robust planning, based on risk assessment of the supply and demand chain. The concepts of supply chain management (SCM), and its extension demand chain management (DCM), have been at the center of much recent research. One of the reasons for this is that, over the last years, a significant number of information systems have emerged, which claim to support the concept. The paper argues that these systems mostly adopt a myopic view of planning, based on pure deterministic planning methods. It demonstrates that such an approach fails to coop with the considerable uncertainty of the planning information. The proposed robust planning paradigm is then introduced and its impact explained, using the well-known example of the beer game. It holds the promise of reducing the number of re-planning cycles, through a better characterization of the expected service level performance over a medium planning horizon. Finally, a case study will show the value of robust planning in a European chemical enterprise. 相似文献

Liquidity biases in asset pricing tests 总被引:1,自引:0,他引:1
Microstructure noise in security prices biases the results of empirical asset pricing specifications, particularly when security-level explanatory variables are cross-sectionally correlated with the amount of noise. We focus on tests of whether measures of illiquidity, which are likely to be correlated with the noise, are priced in the cross-section of stock returns, and show a significant upward bias in estimated return premiums for an array of illiquidity measures in Center for Research in Security Prices (CRSP) monthly return data. The upward bias is larger when illiquid securities are included in the sample, but persists even for NYSE/Amex stocks after decimalization. We introduce a methodological correction to eliminate the biases that simply involves weighted least squares (WLS) rather than ordinary least squares (OLS) estimation, and find evidence of smaller, but still significant, return premiums for illiquidity after implementing the correction. 相似文献
