In their out-of-sample predictions of stock returns in the presence of structural breaks, Lettau and Van Nieuwerburgh (2008) implicitly assume that economic agents’ perception of the regime-specific mean for the dividend-price ratio is time-invariant within a regime. In this paper, we challenge this assumption and employ least squares learning with constant gain (or constant-gain learning) in estimating economic agents’ time-varying perception for the mean of dividend-price ratio. We obtain better out-of-sample predictions of stock returns than in Lettau and Van Nieuwerburgh (2008) for both the U.S. and Japanese stock markets. Our empirical results suggest that economic agents’ learning plays an important role in the dynamics of stock returns. 相似文献

The first “Made in Germany, Designed for Chinese” luxury cruise, Norwegian Joy, announced an unexpected Chinese-market-withdrawal decision on July 14th, 2018, less than a year after her maiden voyage from Shanghai. How does customer satisfaction change as a response to a cruise's market-withdrawal decision? By resorting to the confirmation of expectation theory, our paper highlights satisfaction as being a function of the baseline effect of expectations plus perceived disconfirmation of expectations. We propose that customer satisfaction will rise because the withdrawal decision implies strategic mistake of the cruise and therefore lowers customer expectation. Drawing on customers' comments on the largest travel agency website in China, we conducted sentiment analysis and used ‘difference in difference’ statistical approach to test our hypothesis. Results show that customer satisfaction increased after Norwegian Joy's withdrawal announcement. 相似文献

We assess the conditional relationship in the time-frequency domain between the return on S&P 500 and confirmed cases and deaths by COVID-19 in Hubei, China, countries with record deaths and the world, for the period from January 29 to June 30, 2020. Methodologically, we follow Aguiar-Conraria et al. (2018), by using partial coherencies, phase-difference diagrams, and gains. We also perform a parametric test for Granger-causality in quantiles developed by Troster (2018). We find that short-term cycles of deaths in Italy in the first days of March, and soon afterwards, cycles of deaths in the world are able to lead out-of-phase US stock market. We find that low frequency cycles of the US market index in the first half of April are useful to anticipate in an anti-phasic way the cycles of deaths in the US. We also explore sectoral contagion, based on dissimilarities, Granger causality and partial coherencies between S&P sector indices. Our findings, such as the strategic role of the energy sector, which first reacted to the pandemic, or the evidence about predictability of the Telecom cycles, are useful to tell the history of the pass-through of this recent health crises across the sectors of the US economy. 相似文献

The role of social proximity in professional CEO appointments: Evidence from caste/religion‐based hiring of CEOs in India 下载免费PDF全文
Research Summary: The role of homophily in CEO appointments at the largest corporations is an important subject in corporate governance. This subject is particularly important in a country like India where a multitude of religions, castes, and communities form its social fabric. We test for the role of homophily in professional CEO appointments in India by empirically examining the preference for same caste/religion CEOs by the largest firms. Using a unique dataset, assembled by detailed identification of castes/religions from family names and counterfactuals obtained through the Coarsened Exact Matching technique, we find that caste/religion plays a crucial role in CEO selection as a source of information (positive discrimination). The evidence is not consistent with its use to pursue taste‐based preferences (negative discrimination). Managerial Summary: We test for the role of homophily in the appointments of CEOs in India by empirically examining the preference for same caste/religion CEOs by the largest firms. We find that caste/religion plays an important role in CEO selection, i.e., as a form of information or “positive discrimination.” The evidence is not consistent with its use to pursue taste‐based preferences or “negative discrimination.” 相似文献

This study integrates insights from Self-Determination Theory and Boundary Theory to present scenarios on how flexible workplace designs can trigger multiple motivational processes underlying gendered work/nonwork integration behaviors, and how these affect work/life conflict. We disentangle processes underlying work engagement and work/life conflict, explaining the paradoxical outcomes found with regard to gender inequality in terms of work/life performance, satisfaction, and health. Policy makers and organizations need an increased understanding and a reconceptualization of these issues, realizing that the ideal worker does not exist. Instead, a long-term perspective is needed in order to truly realize the potential benefits of flexible workplace designs for all stakeholders. Organizations need to take responsibility for preventing individual workers’ depletion and stimulating the regeneration of workers’ resources. 相似文献

The conventional partial adjustment model, which focuses on leverage evolution, has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage. We propose and estimate a financing-based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution. The speed of adjustment (SOA) is firm-specific and stochastic, and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit. Overall, we find expected SOA from active rebalancing (30%) more than doubles what is expected from mechanical mean reversion alone (13%). 相似文献

Se presenta un análisis contextualizado de las resoluciones judiciales dictadas en Côte d'Ivoire entre 1971 y 2013 en el marco del código general del trabajo. La jurisprudencia y las entrevistas cualitativas con actores institucionales muestran que las prácticas innovadoras derivan de la aplicación del código por inspectores y jueces que equiparan el trabajo doméstico a cualquier otro, lo que impide abordar su especificidad. Tras reafirmar que la regulación del trabajo doméstico debe englobar su dualidad (trabajo como otro cualquiera, pero diferente de todos los demás), se aboga por la creación de una comunidad internacional de aprendizaje sobre trabajo decente para los trabajadores domésticos. 相似文献

This study examines the previously unexplored mediating role of work engagement in the link between creative work involvement and the relational resources embedded in supervisor‐follower exchanges. We studied three relational resources inherent to the exchanges between followers and their supervisors: trust in supervisor, goal congruence, and relationship informality. Data were captured from IT professionals working at four well‐established IT companies in Ukraine. The findings show that relationship informality and goal congruence positively affect employees' creative work involvement, yet these effects are less pronounced when controlling for work engagement. The significance and implications of these findings for research and practice are discussed. Copyright © 2016 ASAC. Published by John Wiley & Sons, Ltd. 相似文献
