We suggest that the distortion of the positive risk–return relation in the ICAPM is a consequence of trading by informed investors to exploit mispricing. We hypothesize and demonstrate that a non-positive (strongly positive) risk–return relation following positive (negative) market returns is attributed to short-selling (purchasing) of overpriced (underpriced) stocks along with optimistic (pessimistic) expectations conditional on good (bad) market news. We verify this asymmetry in the risk–return relation through the indirect risk–return relation conditional on good (bad) market news. We also find that the attenuation (reinforcement) of the positive risk–return relation is more profound in high- (low-) sentiment periods.  相似文献

Funding for infrastructure projects recently shows that debt has a portion more than equity, triggering public debates. Therefore, leverage as an instrument to measure the ability and willingness of project sponsors to fund becomes the utmost importance to discuss. Relating to leverage, risk and government participation are two main factors that can explain the choice of funding decisions by the project sponsors. For this reason, this study would analyze the effect of risk and government participation on leverage through the two main sectors of infrastructure projects, namely the transportation sector and the energy sector, and derivating risk to political risk and financial risk. The objects of research were 976 infrastructure projects listed in the Asian Development Bank during 2007−2016. We use censored regression to examine the model by infrastructure sectors, both as individual and through interaction effects. The analysis showed that overall, leverage of infrastructure projects was rather influenced by financial risk than by political risk. However, the leverage of infrastructure projects in the transportation sector was more vulnerable to risk than that in other sectors.  相似文献

基于1997~2017年的跨国面板数据,构建双向固定效应模型研究实际汇率对劳动参与率的影响效应。研究结果显示:(1)实际汇率升值会降低劳动参与率,贬值则提升劳动参与率;(2)实际汇率变动主要通过影响劳动力需求,进而影响劳动参与率;(3)相比于高收入国家,中低收入国家实际汇率变动对劳动参与率的影响更显著。因此,汇率政策的制定需要考虑其对劳动参与率的影响。在中国经济发展过程中,也应采取适当措施来抵消人民币升值对劳动参与率的不良影响。  相似文献

重大水利工程项目决策社会稳定风险评估中,公众是重要的参与主体,个体间生活环境、知识背景及心理素质的差异性会直接影响稳评结果。公众参与成熟度是公众参与的衡量要素,由能力成熟度和心理成熟度两个方面构成。从能力与心理两个角度设计调查问卷,运用结构方程模型,探究内部影响路径。结果表明,公众参与心理成熟度直接影响能力成熟度,而能力成熟度又通过参与意愿影响着心理成熟度,两者间存在相互影响的关系。政府可以通过开展道德素质教育,改善公众参与动机,以提高公众参与心理成熟度及能力成熟度,最终整体提高公众参与成熟度,保证稳评工作的质量,提升重大水利工程项目决策科学性。  相似文献

We argue that multinationals from different home countries have different technologies and input sourcing behavior. These differences impinge on potential productivity spillovers through backward linkages of multinationals and such effects also differ across host local firms depending on their absorptive capacity. Using a panel of Cameroonian manufacturing firms over the period 1993 to 2005, we find supportive evidence of these arguments. There is a negative relationship between the presence of American and European affiliates in downstream sectors and the productivity of Cameroonian firms in the supplying industries and a positive correlation in the case of Asian affiliates. The absorptive capacity of Cameroonian firms mainly explains these divergent results.  相似文献

The rise of early retirement in Europe is typically attributed to the European system of taxes and transfers. A model with an imperfectly competitive labor market allows us to consider also the effects of bargaining power and of matching efficiency on pre‐retirement. We find that lower bargaining power of workers and declining matching efficiency have been important determinants of early retirement in France and Germany. These structural changes, combined with early retirement transfers and population aging, are also consistent with the employment and unemployment rates, labor share and seniority premia.  相似文献

We apply an affordance lens on qualitative data from three case organisations using a digital voice channel providing employees with the opportunity to speak up via answering periodic mini‐surveys and making comments in an anonymous mini‐forum. We find that imbrications of material and social agencies (i.e., the voice channel's features and managerial reactions to voice) in the respective organisational contexts culminate in employees perceiving the channel as either affording or constraining voice, leading to perceived voice outcomes that eventually encourage or discourage them to speak up. Whether voice is encouraged or discouraged partly results from the mere interaction between employees and the digital voice channel independent of managerial reactions. Our findings thus challenge the emphasis on managerial behaviour and reactions to voice in explaining voice behaviour and outcomes in extant literature.  相似文献

This paper empirically examines individual and joint effects of two types of customer participation (CP)—mandatory and replaceable—within a mobile app on bakery purchase behavior. This research conducts a field experiment to track customer decisions on whether to participate in in-app CP events—store loyalty program enrollment and store satisfaction survey—and whether to change their purchasing amount and frequency. After controlling other influencing factors, the authors performed ANOVA with the sample of 19,065 bakery customers’ behavioral decisions. The results confirm that mandatory CP has a positive effect on purchase behavior, while replaceable CP has mixed effects across stores. In addition, the results confirm that customers who engaged in both types of CP increased their purchase amount and frequency, compared to customers who engaged in one type or neither. The study suggests hospitality firms should motivate customers to engage in mandatory and replaceable CP to enhance customer loyalty cost-effectively.  相似文献

Previous research investigating cross‐border M&As (CBM&As) by emerging economies (EEs) provided contrasting evidence on the value enhancement role of investor protection rules. We conduct a new empirical study to address the issue with an accurate sample selection of bidders from more homogeneous developing countries and transactions on developed countries only. Our analysis over the 1997–2012 period on a sample of M&A deals by companies from Brazil, Russia, India, China, and South Africa (BRICS) does not provide evidence that better institutional standards in the destination country are rewarded by the local stock market. We find that foreign governance quality is not associated with positive excess stock returns around the announcement date. Rather, these returns are affected by firm‐specific and deal‐specific factors, such as the relative deal size, the listed status of the target company, and the acquirer size. Comparison with other studies on excess returns for emerging markets (including BRICs) suggests that the results could be driven at least partially by country choice.  相似文献
