Elections with platform and valence competition   总被引:1,自引:0,他引:1  
We study a game in which candidates first choose platforms and then invest in costly valences (e.g., engage in campaign spending). The marginal return to valence depends on platform polarization—the closer platforms are, the more valence affects the election outcome. Consequently, candidates without policy preferences choose divergent platforms to soften valence competition. Moreover, exogenous increases in incentives for valence accumulation lead to both increased valence and increased polarization—the latter because candidates seek to avoid the costs of extra valence. As a result, the increase in valence is smaller than it would have been with exogenous platforms. Finally, the model highlights the overlooked substantive importance of common modeling assumptions. Changing the source of uncertainty in our model from noise around the median voter's ideal point to a shock to one candidate's valence (as is common in the literature) leads to complete platform convergence for all parameter values.  相似文献

This study investigates antecedents of corporate social responsibility (CSR) in multinational corporations’ (MNCs’) subsidiaries. Using stakeholder theory and institutional theory that identify internal and external pressures for legitimacy in MNCs’ subsidiaries, we integrate international business and CSR literatures to create a model depicting CSR practices in MNCs’ subsidiaries. We propose that MNCs’ subsidiaries will be likely to adapt to local practices to legitimize themselves if they operate in host countries with different institutional environments and demanding stakeholders. We also predict that MNCs’ subsidiaries will be likely to adapt to local practices to avoid spillover effects if their parent companies suffer major legitimacy problems at home or abroad. However, we speculate that MNCs’ subsidiaries will be less likely to adapt to local practices if they are strongly annexed to their parent companies and the benefit to gain internal legitimacy outweighs external legitimacy. This article contributes to the discourse on CSR across borders by exploring the antecedents of CSR practices in MNCs’ subsidiaries at social and organizational levels, and integrating institutional and stakeholder views. We provide a number of propositions for future studies and explore implications for practitioners.  相似文献

The estimation of physical intensity processes in the context of default risk is investigated here. Using data from Moody's Corporate Bond Default Database, a term structure of default probabilities for different rating classes is constructed each year from 1970 to 2001. Two specifications used for modeling the dynamics of the (risk‐neutral) intensity process in the bond‐pricing literature are then examined empirically: the Ornstein–Uhlenbeck and square‐root cases. The results reveal that the Ornstein–Uhlenbeck case is not an adequate modeling alternative with a rejection of this specification in five out of seven credit classes and nonsignificant mean reverting behavior for all credit classes. The square‐root case obtains better results with four credit classes out of seven for which this specification cannot be rejected and significant mean reversion parameters in many cases. © 2008 Wiley Periodicals, Inc.

This article offers an argument for how genetic factors may influence the tendency of people to engage in entrepreneurial activity, and describes four mechanisms through which genetic factors could operate. It also explores ways that researchers can use quantitative and molecular genetics to examine entrepreneurship, and discusses the potential implications of a genetic perspective for management research on entrepreneurship.  相似文献

This special issue of the Journal of Business Research features eleven articles selected from the papers presented during the fourth meeting of the Royal Bank International Research Seminar which took place in Montreal at the John Molson School of Business, Concordia University, September 23 and 24, 2007. They cover topics related to culture and marketing communications, consumer socialization, materialism, identity and religiosity, service quality, language effects, consumer revenge behavior and government actions.  相似文献

The current empirical study examines the intention to use and subsequent implementation of a supply chain technology. Specifically, the authors extend the technology acceptance model (TAM) to incorporate the state of the technology environment (technological turbulence) and the extent to which other supply chain technologies have already been adopted by the firm (technological breadth). A series of seemingly unrelated regressions (SUR) were used to analyze survey data from 195 respondents. The results show that in technologically turbulent environments, the relationships between the firm's perceived usefulness and ease of use and the firm's intention to use a supply chain technology are stronger. The study also finds that the relationship between the firm's intention to use a supply chain technology and the implementation of the technology is weaker in firms with greater technological breadth.  相似文献

Leadership development and practice have traditionally been quite narrow, with a decided focus on the analytical realm of leadership. However, the contemporary climate of corporate scandal and resultant loss of societal confidence, coupled with the evolving demands, needs, and expectations of employees, point to the potential need for a more holistic approach to leadership. Thus, this article proposes how management education and leadership development programs can develop holistic leaders that are adept at operating in the analytical, conceptual, emotional, and spiritual domains of leadership practice. An integrated model for holistic leadership development and practice that addresses all four of these domains is proposed, and grounded in both established and emerging leadership development theory. Additionally, a leadership development classification scheme is proposed based on classroom, job, and organizational contexts.  相似文献

Conventional wisdom holds that in markets with positive feedbacks being first to market can matter more than product quality. In this paper, we test that intuition within a generalized Pólya urn model. We find that if we assume constant feedbacks, in the long run, higher quality products dominate the market regardless of initial market shares, contradicting the common wisdom. However, when we allow for variable feedbacks, initial advantages persist almost indefinitely. Thus, the choice of whether to rush to market or focus on quality depends on market characteristics such as whether the positive feedbacks result from more consistent returns to scale or from more variable social influences.  相似文献

The objective of this paper is to develop conditions for global multivariate comparative risk aversion in the presence of uninsurable, or background, risks, and thus generalize Kihlstrom and Mirman [1974] and Karni [1979,1989]. We analyze von Neumann-Morgenstern (VNM) utility functionsas well as smooth preference functionals which are nonlinear in distribution but locally linear in probabilities. In each case we provide an economic application which illustrates how our theorems can be used. We analyze a risk sharing, a portfolio choice, and a labor supply problem for VNM utility functions, and the optimal allocation of effort to risky technologies in the presence of a random supply (or quality) of a public good for nonlinear preference functionals. We consider thecase where the random variables are mean-independent as well as the case where they are independent. In the labor supply application for VNM utility functions, we show that if the two risks are independent, the comparative statics effect of greater risk aversion on labor supply in the presence of a background non-wage income risk is determined by a monotonic relationship between labor supply and the wage rate under certainty. That is, we extend the applicability of the Diamond-Stiglitz [1974]-Kihlstrom-Mirman [1974]single-crossing property to the case where an independent background risk is present.  相似文献
