This study draws from the corporate governance literature to investigate the implications of board involvement for international joint ventures (IJVs). We extend recent corporate governance research on the value of board involvement by investigating unique sources of complexity related to the nature of the IJV. We argue and find that board involvement can enhance the performance of IJVs, particularly for collaborations that are complex in nature due to their broad functional scope as well the level of market overlap between IJV parents. We complement recent research on joint venture control that has focused on the antecedents and types of control, as well as studies on formal (e.g. contractual safeguards and monitoring) and informal governance mechanisms (e.g. trust) by providing empirical evidence that IJV board involvement is valuable when directors undertake their control and coordination responsibilities. We advance corporate governance research by providing evidence that joint ventures possess several unique characteristics that shape the value of board involvement, thereby showing that applications of corporate governance theory to joint ventures are useful, but should be made with care.  相似文献

Financial time series are often non‐negative‐valued (volumes, trades, durations, realized volatility, daily range) and exhibit clustering. When joint dynamics is of interest, the vector multiplicative error model (vMEM; the element‐by‐element product of a vector of conditionally autoregressive scale factors and a multivariate i.i.d. innovation process) is a suitable strategy. Its parameters can be estimated by generalized method of moments, bypassing the problem of specifying a multivariate distribution for the errors. Simulated results show the gains in efficiency relative to an equation‐by‐equation approach. A vMEM on several measures of volatility justifies a joint approach revealing full interdependence.

Answering a call for a more fully developed concept of work-life balance (WLB), we use person-environment fit and control theories to develop a model of WLB incorporating the work, family, and personal domains. We propose a cybernetic model which recognizes that individuals have a desired balance among the three domains that serves as a standard against which they compare their perceptions of WLB at any given point in time. Our cybernetic model suggests that individuals will seek to restore balance when a negative imbalance is perceived. Further we propose that role senders and resources in the domains, as well as anticipated future WLB and retrospective perceptions of WLB also affect desired balance and actions. We discuss the implications of the proposed model for future research and practice.  相似文献

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.  相似文献

This article examines the development of supply management in the U.S. to assess its progress towards academic disciplinary status. A comparison of the fields of business administration and public administration indicates that supply management is more developed in the former than in the latter, which inhibits its disciplinary status. Various reasons for this uneven development in the two fields are explored. The paper argues that a paradigm shift must occur for public supply management, which will re-orient it around the concept of the public interest. This will require public supply professionals to participate strategically in public policy-making in order to ascertain and promote the public interest. A policy framework is used to illustrate this re-orientation and to suggest directions for further research.  相似文献

A welfare framework for the analysis of the spatial dimensions of sustainability is developed. It covers agglomeration effects, interregional trade, negative environmental externalities, and various land use categories. The model is used to compare rankings of spatial configurations according to evaluations based on social welfare and ecological footprint indicators. Five spatial configurations are considered for this purpose. The exercise is operationalized with the help of a two-region model of the economy, that is, in line with the ‘new economic geography.’ By generating a number of numerical ‘counter-examples,’ it is shown that the footprint method is inconsistent with an approach aimed at maximum social welfare. Unless environmental externalities are such a large problem that they overwhelm all other components of economic well-being, a ‘spatial welfare economic’ approach delivers totally different rankings of alternative land use configurations than the ecological footprint.   相似文献

We show that the entry of private profit-maximising firms makes the consumers worse off compared to having a nationalised monopoly. Such entry increases the nationalised firm’s profit, industry profit, and social welfare, at the expense of the consumers. Our result is important for competition policy.  相似文献

This study assesses the impact of parental involvement laws on adolescent abortion rates and pregnancy rates. The analysis estimates abortion rate and pregnancy rate models using state-level data pooled over time for adolescents aged 15–17 compared to older teens aged 18–19 and adults aged 20–44. The results indicate that parental involvement laws reduce adolescent abortion rates and may, to a lessor degree, reduce adolescent pregnancy rates. Thus, the findings imply that enforcement of parental involvement laws will increase adolescent fertility rates.  相似文献

In data envelopment analysis (DEA), there are two principal methods for identifying and measuring congestion: Those of Färe et al. [Färe R, Grosskopf S. When can slacks be used to identify congestion. An answer to W. W. Cooper, L. Seiford, J. Zhu. Socio-Economic Planning Sciences 2001;35:1–10] and Cooper et al. [Cooper WW, Deng H, Huang ZM, Li SX. A one-model approach to congestion in data envelopment analysis. Socio-Economic Planning Sciences 2002;36:231–8]. In the present paper, we focus on the latter work in proposing a new method that requires considerably less computation. Then, by proving a selected theorem, we show that our proposed methodology is indeed equivalent to that of Cooper et al.  相似文献

The present study shows how the evaluation of sport motivation according to Achievement Goal Theory is different if the criteria used are predominant goal orientation or motivational profile combination, as well as presenting its relationship with other variables such as the amount of sport practise or the level of competition and success achieved. Seventy two men and women participated, all students of Physical Educational and Sport Science, completing the Questionnaire on Motivational Orientation in Sport ((Guivernau and Duda, Revista de Psicología del Deporte, 5, 1994) a Spanish adaptation of the Task and Ego Orientation in Sport Questionnaire, TEOSQ, (Duda, J Sport Exerc Psychol, 11, 1989)). The results showed the existence of different motivational relationships with variables of the practise of sport, depending on the type of profile used. Finally, the practical implications of these findings are discussed with respect to the motivational climate generated in the teaching of Physical Education.  相似文献
