Employment effects of business dynamics: Mice, Gazelles and Elephants   总被引:2,自引:0,他引:2  
Much of the theoretical work on industry dynamics focuses on the role of ‘noisy’ selection and incomplete information on firm entry and survival. We extend this research by looking at the impact of firm heterogeneity on employment effects for 320 U.S. Metropolitan Statistical Areas (MSA). We find that only start-ups with greater than 20 and less than 500 employees have persistent employment effects over time and only in large diversified metropolitan regions. Therefore, both the type of entry (Gazelles) and the characteristics of the region are important for employment growth.

This paper re-examines the link between new firm formation and subsequent employment growth. It investigates whether it is possible to have the wrong type of entrepreneurship—defined as new firm formation which leads to zero or even negative subsequent employment growth. It uses a very similar approach to that of Fritsch and Mueller (Regional Studies, 38(8), 961–976, 2004), confirming their findings that the employment impact of new firm formation is in three discrete phases. Then, using data for Great Britain, the paper shows the employment impact of new firm formation is significantly positive in the high-enterprise counties of Great Britain. However, for the low-enterprise counties, it shows that new firm formation has a negative effect on employment. Of the 15 low-enterprise regions, eight are Scottish (of nine Scottish regions in our data base) and three are North East Counties (of four). Our findings imply that having the “wrong type of entrepreneurship” is indeed possible.

Organizational governance has historically focused around the perspective of principals and managers and has traditionally pursued the goal of maximizing owner wealth. This paper suggests that organizational governance can profitably be viewed from the ethical perspective of organizational followers – employees of the organization to whom important ethical duties are also owed. We present two perspectives of organizational governance: Principal Theory that suggests that organizational owners and managers can often be ethically opportunistic and take advantage of employees who serve them and Principle Theory that focuses on guiding principles that are sometimes taken too far in organizations. In introducing these two new organizational governance perspectives, we offer insights into the value of rethinking ethical duties owed to organizational followers.

The industrial sales force is the primary source of information about the competitive environment. Differences of perceptions of that environment between the national sales manager and the firm president in small industrial firms may reflect inadequate environmental information input into strategic decision-making. The sales force is a major element in implementation of strategy and differences between perceptions of firm strategy may reflect inadequate coordination and communication between the chief strategy decision-maker and the manager who is responsible for implementing that strategy in the market place. It would be expected that these differences in perceptions would impact negatively strategy formulation and execution resulting in unsatisfactory firm performance. This study surveyed the environmental and strategy perceptions of presidents and national sales managers in small to medium-sized industrial firms as well as presidents' satisfaction with firm profitability and marketing/sales effectiveness. The average absolute difference in environment perceptions has a negative relationship with satisfaction with profit. The average absolute difference in strategy perceptions has a negative relationship with marketing/sales effectiveness. This latter relationship is especially strong in an environment high in capital spending variation and for larger firms. The authors suggest implications for managers based on these results.  相似文献

We investigate the effects of new business formation on employment change in German regions. A special focus is on the lag-structure of this effect and on differences between regions. The different phases of the effects of new business formation on regional development are relatively pronounced in agglomerations as well as in regions with a high-level of labor productivity. In low-productivity regions, the overall employment effect of new business formation activity might be negative. The interregional differences indicate that regional factors play an important role.

Incubation is a process whereby the firm nurtures breakthrough discoveries and inventions to test their potential as new business platforms. The recent emergence of organizational roles associated with innovation incubation shows that internal incubation is becoming recognized as an important organizational capability. This development also suggests that firms that invest in discovery for competitive advantage recognize a need to leverage that investment more fully. While case studies describe incubation activities and note their importance, empirical research linking this capability to firm performance is limited. The current study represents an initial attempt at exploring the relationship empirically. Our main finding is that financial markets have difficulty valuing a firm's exploratory discovery investments and that the presence of an incubation capability positively moderates the impact of such investments on firm market valuation. The implication of this result is that investments in certain types of R&D may be suboptimized if there is not a parallel investment in a capability to incubate the opportunities that arise from potentially breakthrough inventions.  相似文献

Prior competitive dynamics research has drawn on theories of information processing to model the subjective antecedents of executives' retaliation choices. This prior work has made great progress in developing our understanding of the retaliation choices most firms will make to a given type of attack. What the information processing perspective has not been able to do is explain firm‐specific behavior to predict which competitive moves individual firms will challenge, or explain why individual firms differ in the types of actions that they are most likely to challenge. The goal of this paper is to sharpen the theoretical and empirical focus on predicting firm‐level retaliation proclivities. We leverage managerial cognition research to examine the relationship between firm‐level differences in the cognitive frameworks that executives possess, and firm‐level differences in whether and how quickly firms challenge a market move. Results from a longitudinal study of the airline industry suggest that the addition of a cognitive perspective provides important insights into competitive retaliation.

The recent market turmoil has brought attention to how deregulation of the financial sector may affect risk. The purpose of our study is to examine the market's perception of risk associated with deregulation. We accomplish this by decomposing security risk around deregulation into systematic and unsystematic risk. We examine deregulation of several industries and find a consistent pattern of risk adjustment to deregulation, whereby the increase in security risk is temporary and largely unsystematic.  相似文献

Public private partnerships (PPP) are an established model for most governments internationally to provide infrastructure-based services, using private finance. Typically the public authority will sign a contract with a special purpose vehicle (SPV), which, because of the holistic nature of PPP, in turn sub-contracts the finance, design, construction, maintenance and soft services to companies that are often related to its shareholders. Thus there is a considerable network of linked organisations that together procure and provide the PPP project.While there is an increasing body of research that examines these PPP projects, much of it is interview or case study based so that the evidence is drawn from a small number of interviews or cases in specific sectors. It also focuses on the public sector procurer and the private sector contractor in the network of organisations. Although it has been recognised that the perceptions of the financiers may vary from those of other key PPP players there is much less research that focuses on the financiers.In this paper we report the results of a postal questionnaire survey, administered to 109 providers of senior debt and equity, from which the response rate was just less than 40%. We supplement these findings with a small number of illustrative quotes from interviewees, where the cited quote represents a commonly held view. We used SPSS and Nvivo to analyse the data.The findings show that when assessing PPPs financiers perceive a very wide range of risks as important, and that it is important to them that many of these risks are either insured or allocated to sub-contractors. When considering participating in PPPs, financiers agree that working with familiar partners on familiar projects and in familiar sectors is important, which may raise barriers to entry and undermine competitive processes.  相似文献

Automation and trading speed are increasingly important aspects of competition among financial markets. Yet we know little about how changing a market's automation and speed affects the cost of immediacy and price discovery, two key dimensions of market quality. At the end of 2006 the New York Stock Exchange introduced its Hybrid Market, increasing automation and reducing the execution time for market orders from 10 seconds to less than one second. We find that the change raises the cost of immediacy (bid-ask spreads) because of increased adverse selection and reduces the noise in prices, making prices more efficient.  相似文献
