This paper examines whether common ownership – i.e., instances where investors simultaneously own significant stakes in competing firms – affects voluntary disclosure. We argue that common ownership (i) reduces proprietary cost concerns of disclosure, and (ii) incentivizes firms to “internalize” the externality benefits of their disclosure for co-owned peer firms. Accordingly, we find a positive relation between common ownership and disclosure. Evidence from cross-sectional tests and a quasi-natural experiment based on financial institution mergers help mitigate concerns that our results are explained by an omitted variable bias or reverse causality. Finally, we find that common ownership is associated with increased market liquidity.  相似文献

In this article, we develop, and empirically test, a moderated mediation model of the effects of flexible leave on employees' organizational attachment. Drawing on a social exchange framework and signaling theory, we explore how the material and non-material nature of exchange between the employer and employee shapes their relationship. First, we show that the relationship between the availability of flexible leave and organizational attachment is shaped by two competing mediators, perceived organizational support (POS) and perceived flexibility stigma. Second, we delineate between availability and use of the policy, to show how the effect of POS is enhanced and perceived flexibility stigma reduced, with use. Our findings demonstrate that the relationship between the availability of flexible leave and organizational attachment is complex, but is enhanced through use of flexible leave. We contribute toward HRM scholarship about the relationship between employees' experience of HR practices and their corresponding impact on employees' subsequent behavior.  相似文献

Standard finance theory suggests that managers invest in projects that, in expectation, produce returns that justify the use of capital. An underlying assumption is that managers have the information necessary to understand the distributional properties of the pay‐offs underlying the decision. This paper examines firm investment behavior when managers are likely to find it more challenging to develop expectations of pay‐offs, namely during periods of increased macroeconomic ambiguity. In particular, we examine how macroeconomic ambiguity – proxied by the variance premium (Drechsler, 2010 ) and the dispersion in forecasts of corporate profits from the Survey of Professional Forecasters (Anderson et al., 2009 ) – impacts managerial capital investment and cash holdings. Consistent with ambiguity theory, we find that macroeconomic ambiguity is negatively associated with capital investment and positively associated with cash holdings. These results are robust to alternative explanations related to risk, investor sentiment and economic conditions. Moreover, consistent with recent theoretical real options literature, we find that ambiguity reduces the value of investment opportunities, while risk increases the value of such opportunities. Overall, these findings provide initial empirical evidence on the economic distinction between ambiguity and risk with respect to managerial investment and cash holdings.  相似文献

Y is conditionally independent of Z given X   if Pr{f(y|X,Z)=f(y|X)}=1{f(y|X,Z)=f(y|X)}=1 for all y on its support, where f(·|·)f(·|·) denotes the conditional density of Y   given (X,Z)(X,Z) or X.X. This paper proposes a nonparametric test of conditional independence based on the notion that two conditional distributions are equal if and only if the corresponding conditional characteristic functions are equal. We extend the test of Su and White (2005. A Hellinger-metric nonparametric test for conditional independence. Discussion Paper, Department of Economics, UCSD) in two directions: (1) our test is less sensitive to the choice of bandwidth sequences; (2) our test has power against deviations on the full support of the density of (X,Y,ZX,Y,Z). We establish asymptotic normality for our test statistic under weak data dependence conditions. Simulation results suggest that the test is well behaved in finite samples. Applications to stock market data indicate that our test can reveal some interesting nonlinear dependence that a traditional linear Granger causality test fails to detect.  相似文献

  • The museum sector has undergone considerable change in the last few decades, which has been a result of both internal and external forces. The topic of pricing in museums, however, has attracted little interest from researchers in the field despite the sector's need to understand it better. This study aimed to address this gap in knowledge. Results of a comprehensive literature review on pricing highlight that the topic of pricing in museums is problematic, as a range of issues, social, political and often value-laden, must be considered before pricing decisions can be made. The study highlights that there is diversity in the sector with regard to pricing, but that museums generally adopt a unilateral approach to pricing. Researchers in entrepreneurial marketing have noted that conventional pricing theory is being turned on its head and they argue that deciding what prices to charge represents one of the more entrepreneurial strategies for organisations. This study indicates that, within the context of museums, marketers are failing to recognise and capitalise on such pricing opportunities. Approaches to setting multiple museum pricing strategies, depending on the market context, are proposed in this paper. In this way, knowledge of museum pricing can optimise the organisational outcomes of museums while continuing to meet their social responsibilities.

The crash of the French stock market in 1882 presented the Paris Bourse with its worst crisis of the nineteenth century. Its structure was similar in key respects to today’s futures markets, with a dominant forward market leading the Bourse to adopt a common fund to guarantee transactions and liquidity. While this mutualization of risk protects clients and brokers from idiosyncratic shocks, it is generally assumed that it also provides considerable protection against systemic shocks, as no twentieth century exchange has been forced to shut down. Using new archival data, this paper shows how a stock market crash overwhelmed the Bourse’s common fund. Only an emergency loan from the Bank of France, intermediated by the largest banks, prevented a closure of the Bourse.

Multi-purpose recreation facilities (MPRFs) are a popular setting for physical activity and it is therefore important that they are safe for all patrons. However, the attitudes of MPRF users towards safety are a potential barrier to the success of injury prevention programmes implemented within MPRFs. This article reports a survey of the safety attitudes of over 700 users of four indoor MPRFs. Factor analysis of 12 five-point Likert scale statements showed that the attitudes clustered around three major dimensions - the importance of safety, the benefits of safety and the perceptions of injury risk. Together, these three dimensions accounted for 49% of the variability in the attitudes. More than 85% of respondents agreed/strongly agreed that: safety was an important aspect of physical activity participation; being injured affected enjoyment of physical activity; people should adopt appropriate safety measures for all physical activity; and individuals were responsible for their own safety. The MPRF users, particularly women and older people, were generally safety conscious, believed in adopting safety measures, and were willing to take responsibility for their own safety. Facility managers can be confident that if they provide evidence-based injury prevention interventions in these settings, then users will respond appropriately and adopt the promoted behaviours.  相似文献

A conceptual model tested the leisure constraints negotiation process of outdoor recreation: motivation and the constraints to participate likely influenced by negotiation efforts. Higher motivation to participate encourages using negotiation strategies and resources to overcome constraints. Experiencing constraints was thought to trigger negotiation efforts. Drawing from social cognitive theory, negotiation-efficacy was proposed to encourage motivation, diminish the perception of constraints and promote negotiation efforts, which indirectly influenced positive participation. The model tested used data collected from a random sample of Arizona residents through hierarchical confirmatory factor analysis and structural equation modeling. Results support the conceptual model and suggest the constraints negotiation process is a dynamic interaction of influences promoting outdoor recreation participation.  相似文献
