An analysis using British matched employer-employee data finds that workers in establishments operating employee participation schemes feel that they have greater influence over their jobs. Schemes involving broader forms of participation, such as representative participation and briefing groups, are shown to be more strongly associated with greater influence than those of a more focused type, such as quality circles and work teams. There is little evidence of a strong positive interaction between these types of schemes.  相似文献

The impact of managerial change on team performance in professional sports   总被引:1,自引:0,他引:1  
Over a quarter-century of match-level data are used to examine the effect of managerial change on team performance in English (association) football, using ordered probit regression. On average, teams that changed their manager within-season are found to under-perform over the following 3 months. Managerial change also increases the variance of the non-systematic component of performance in the short term. The high incidence of within-season managerial change in English football may be a consequence of team owners gambling that an increased variance may help produce an improvement in performance sufficient to stave off the threat of relegation.  相似文献

Employee job rights have become a controversial issue, with some courts ruling employees have a fundamental right in retaining their job. Employment at will and assigning the worker a property right to his job are examined from three paradigms of social interaction. An alternative model is presented, and is more consistent with each of the three paradigms. Rick Molz is Assistant Professor of Management at Clarkson University. He was Vice-president of the Hickson Electric Corp. from 1975–1981. His articles have appeared in such journals as The Journal of Business Strategy and Business Horizons.  相似文献

Information systems, incentives and the timing of investments   总被引:1,自引:0,他引:1  
The purpose of this paper is to study the effects of introducing information systems into a model featuring managerial incentive problems and investment opportunities that are mutually exclusive over time. In a principal-agent model in which a manager (agent) has superior information about investment costs, we introduce information systems, the signals from which are available to both the manager and the owner of the investment opportunity, which allow the owner to decrease the manager's informational advantage.We examine (i) the characteristics of the optimal information systems; (ii) the effects of such information systems on the owner's investment and compensation choices and on the value of the investment opportunity to the owner; (iii) the effects of such information systems on the timing of investment; (iv) the effects of such information systems on the overall probability of investment; and (v) when the owner might want to improve the information system at a particular point in time.  相似文献

In Malawi, population growth has reduced opportunities for farmers to expand and cultivate new land. The country's primary farming population is comprised of smallholders, many who cultivate monocultures of maize (Zea mays). To reduce negative outcomes from this practice, intercropping maize with legumes has been promoted. The sustainable intensification (SI) practice was once widely used, but has declined in recent decades. Little is known about the determinants of intercropping or its role in agricultural development. The objective of this study was to examine the drivers of intercropping among smallholders. We used multiple logistic regression analysis to estimate the determinants of intercropping based on a survey of 324 households. Smallholders who sold legumes were more likely to intercrop, contrary to literature positing intercropping as a practice primarily intended to enhance food security. In addition, complementary SI practices such as fertilizer, manure and compost application were more likely to have occurred on intercropped fields relative to sole maize fields. Furthermore, smallholder farmers appeared to apply more fertilizer to their intercropped fields relative to their sole maize fields. The study highlights the value of including field-level characteristics and household socioeconomic survey data to understand farming practices as a means to inform agricultural policy.

We provide a meta‐analysis of the empirical literature concerning role breadth, defined as the degree to which employees consider organizational citizenship behavior (OCB) to be an inherent part of their job. Results based on a combined sample size of 9,222 showed: (a) Confucian Asians consider OCB as part of their job to a greater extent than do their Anglo counterparts; (b) affiliative kinds of OCB (e.g., helping, conscientiousness, and courtesy) are more likely to be considered part of one's job than are change‐oriented OCB (e.g., voice, taking charge, and initiative); and (c) OCB‐inclusive role breadth correlates strongly with OCB (rc = .43). The implications of these findings for human resources practice, such as competency modeling, employee selection and training, organizational rewards, and employee‐employer/supervisor relations, are discussed. © 2013 Wiley Periodicals, Inc.  相似文献

High-frequency trading dominates trading in financial markets. How it affects the low-frequency trading, however, is still unclear. Using NASDAQ order book data, the authors investigate this question by categorizing orders as either high or low frequency, and examining several measures. They find that high-frequency trading enhances liquidity by increasing the trade frequency and quantity of low-frequency orders. High-frequency trading also reduces the waiting time of low-frequency limit orders and improves their likelihood of execution. The results indicate that high-frequency trading has a liquidity provision effect and improves the execution quality of low-frequency orders.  相似文献

We consider three explanations for public ownership: publicinterest, regulation, and a transaction cost interpretation.We employ a large dataset containing information on the municipalacquisition of U.S. private water companies between 1897 and1915. Those data allow us to isolate the effects of high waterrates, water quality, financial difficulties, extensivenessof distribution system, and the like in determining the probabilityof subsequent municipal takeover of companies that were privatein 1897. After controlling for such factors, we find evidenceconsistent with a transaction cost interpretation of municipalacquisition. We find relatively little support for regulation-basedor public interest interpretations. Our evidence indicates thatmunicipalities were unable to credibly precommit to not expropriatingvalue from private water companies once investments were made,resulting in a rational reduction in investment in water provisionby private companies. Local governments, in turn, used thisrational underinvestment as a pretext for municipalizing privatewater companies.  相似文献

Despite more than three decades of promotion, conservation agriculture (CA) has not been widely adopted by smallholder farmer in sub-Saharan Africa. This low rate of adoption reflects substantial negative evaluation of CA by many smallholder farmers, the causes of which have not been adequately explored in an in-depth, qualitative manner. Hence, we implement the Livelihoods Platforms Approach to explore directly with negatively evaluating farmers the reasons why they chose not to implement CA using semi-structured interviews with 35 farmers from 23 communities in 6 African countries. While there are issues with perceived benefit and relevance, the primary driver of negative evaluation of CA was found to be the feasibility of implementation. The required resources to implement CA (financial, physical, human and informational) are limited by community and institutional constraints which appear unlikely to be overcome through interventions targeted at addressing household resources. More positive evaluation of CA by smallholder farmers requires: (1) development of financially viable CA adoption pathways; (2) incorporation of wider livelihood objectives into a CA ‘package’; (3) re-evaluation of current extension policy; and (4) development of CA-complementary agricultural policies. Without addressing these issues, the potential benefits of CA adoption are unlikely to be achieved in African smallholder systems.  相似文献
