Previous studies document a negative return to equity on the announcement of an SEO. However, the effects of SEO announcements on bonds have received little attention. We find that bondholders experience a significant positive return on the announcement of an SEO and this effect is more pronounced for bonds with lower ratings. We examine alternate explanations for bond market reactions to SEO announcements including the leverage risk reduction, wealth transfer, and information signaling hypotheses. Overall, our results are most consistent with the leverage risk reduction hypothesis. 相似文献

We identify structural breaks in economic growth in 140 countries and use these to define “growth spells:” periods of high growth preceded by an upbreak and ending either with a downbreak or with the end of the sample. Growth spells tend to be shorter in African and Latin American countries than elsewhere. We find evidence that growth duration is positively related to: the degree of equality of the income distribution; democratic institutions; export orientation (with higher propensities to export manufactures, greater openness to FDI, and avoidance of exchange rate overvaluation favorable for duration); and macroeconomic stability. 相似文献

This article examines work to family conflict for Hispanic Business Professionals with varied levels of Hispanic identity.
Based on this study of 971 Hispanics from across the United States, results show that level of Hispanic identity moderates
the relationship between work to family conflict and job satisfaction. The authors posit that identification with a culture
of collectivism may attenuate the negative impact of work to family conflict on job satisfaction, enabling Hispanic professionals
to view work as a way of supporting the family and contributing to the greater good of the groups to which they belong. 相似文献

This paper extends the literature on modelling healthcare cost data by applying the generalised beta of the second kind (GB2) distribution to English hospital inpatient cost data. A quasi‐experimental design, estimating models on a sub‐population of the data and evaluating performance on another sub‐population, is used to compare this distribution with its nested and limiting cases. While for these data the beta of the second kind (B2) distribution and generalised gamma (GG) distribution outperform the GB2, our results illustrate that the GB2 can be used as a device for choosing among competing parametric distributions for healthcare cost data.

Isolated pockets of innovation can be found in projects—such as the novel solution used to redesign the Velodrome roof during the London 2012 Olympics—but there have been few, if any, systematic efforts to manage innovation in a megaproject. This paper presents the initial findings of an ongoing three‐year (2012–2014) action research project between Crossrail and researchers at Imperial College London and University College London. Action research is well suited to a setting where an intervention is required to diagnose and solve an organizational problem and produce scientific findings (Miles & Huberman, 1994; Van de Ven, 2007). Undertaken in collaboration with practitioners, the aim of action research is to transform the research setting through a process of critical inquiry and action. Our engagement with Crossrail aimed to formulate and implement an innovation strategy to improve the performance and outcomes of the project. We identified four stages—or windows of opportunity—to intervene to generate, discover, and implement innovation in a megaproject: (1) the bridging window during the front‐end when ideas, learning, and practices from other projects and industries can be used to create an innovative project process, organization, and governance structure; (2) the engaging window, when tendering and contractual processes can be used by the client to encourage contractors and suppliers to develop novel ideas and innovative solutions; (3) the leveraging window, when all the parties involved—clients, delivery partners, and suppliers—are mobilized to develop novel ideas, new technologies, and organizational practices to improve performance; and (4) the exchanging window at the back‐end, when ideas and resources for innovation can be (re)combined with those of other projects in the wider innovation ecosystem to improve performance. The first two stages had largely occurred when we became involved in the Crossrail project in 2012. Our intervention addressed the final two stages, when we assisted in the development and implementation of an innovation strategy. Core to this strategy was a coordinated mobilization of the innovative capabilities across the project supply chain. Though, to be successful, this approach had to be open enough to span organizational boundaries beyond the supply chain, reaching into the broader ecosystem. The four windows provide a valuable new heuristic for organizing innovation in megaprojects, pointing to areas where project managers can craft targeted innovation interventions and compare their efforts with those of others. 相似文献

Change agency is seen as a key route to reducing the occupational vulnerability of human resource management (HRM). However, few look outside of the HRM context to consider change agency more broadly in organisations. Drawing on a study of change agency units in British organisations, we argue that challenges to occupational credibility and competing jurisdictional claims have wider implications for the role of HR practitioners. In particular, change agency is better seen as replaying rather than resolving the ambiguity of HRM's role and identity in organisations. 相似文献

We study frictionless matching in large economies with and without market imperfections, providing sufficient conditions for monotone matching that are weaker than those previously known. Necessary conditions, which depend on a key analytical object we call the surplus function , are also offered. Changes in the surplus yield valuable information about the comparative statics of matching patterns across environments. We apply our framework to some examples adapted from the literature, accounting for and extending several comparative–static and welfare results. We also explore the dependence of the matching pattern on the type distribution. 相似文献

Seismic waves traveling in the water/sediment or sub-bottom sediment interface have been the subject of considerable interest in underwater acoustics in recent years. Some progress has been made in understanding the propagation and attenuation characteristics of interface waves in different geological environments. However, the generating mechanisms are poorly understood. In particular, what is the acoustic-seismic energy conversion process? As seismic waves involve both time and space parameters it should be able to relate directly the propagation characteristics of the ocean bottom interface waves to the shear properties of the sediments over the propagation area. To address these problems we have applied the wavelet correlation method (WCR) to examine the variations of bottom characteristics and their role in coupling waterborne sound into the sea bottom. To confirm the validity of the developed modeling technique, we applied the wavelet correlation analysis for synthetic seismograms and field data. In this discussion paper we present images of the first and second shear modes and the interface wave component as a function of arrival time and frequency. We also discuss the possibility of inverting phase and group velocity information directly from the wavelet cross-correlation function and propose the way of using the WCR method to predict physical dynamic parameters of marine sediments. 相似文献

Commenting on the Pinochet regime, Friedrich Hayek famously claimed in 1981 that he would prefer a ‘liberal’ dictator to ‘democratic government lacking liberalism.’ Hayek's defense of a transitional dictatorship in Chile was not an impromptu response. In late 1960, in a little known BBC radio broadcast, Hayek suggested that a dictatorial regime may be able to facilitate a transition to stable limited democracy. While Hayek's comments about Pinochet have generated much controversy, this paper neither provides a blanket condemnation of his views (he did not advocate dictatorship as a first-best ‘state of the world’) nor tries to excuse his failure to condemn the Pinochet junta's human rights abuses, but instead provides a critical assessment of Hayek's implicit model of transitional dictatorship. 相似文献
