Under semi-strong market efficiency future returns are unpredictable from previously released information. We test the degree of semi-strong form market efficiency in the credit default swap (CDS) market by examining the relationship between subsequent CDS returns and previously announced quarterly earnings surprises and quarterly accruals, both of which have been the source of stock market anomalies. We conduct our analysis over three time periods: (1) before the credit crisis that spanned from July 2007 to June 2009, (2) during the credit crisis, and (3) after the credit crisis. Both before and after the credit crisis, the CDS market was efficient, exhibiting no systematic relation between subsequent CDS returns and previously announced accounting information. During the credit crisis, however, we find that both quarterly earnings surprises and quarterly accruals are associated with systematic patterns in subsequent CDS returns that are consistent with underreaction to both measures. In the latter stages of the crisis, the pattern reverses, consistent with the CDS market overreacting to both measures although the overreaction is short-lived. Collectively, our results indicate that the CDS market is efficient during periods of relative economic stability but call into question its efficiency during less stable economic periods.  相似文献

We consider estimation and testing of linkage equilibrium from genotypic data on a random sample of sibs, such as monozygotic and dizygotic twins. We compute the maximum likelihood estimator with an EM‐algorithm and a likelihood ratio statistic that takes the family structure into account. As we are interested in applying this to twin data we also allow observations on single children, so that monozygotic twins can be included. We allow non‐zero recombination fraction between the loci of interest, so that linkage disequilibrium between both linked and unlinked loci can be tested. The EM‐algorithm for computing the maximum likelihood estimator of the haplotype frequencies and the likelihood ratio test‐statistic, are described in detail. It is shown that the usual estimators of haplotype frequencies based on ignoring that the sibs are related are inefficient, and the likelihood ratio test for testing that the loci are in linkage disequilibrium.  相似文献

This paper uses the Canadian Labour Force Survey to understand why the level and dispersion of wages have evolved differently across provinces from 1997 to 2013. The faster increase in the level of wages and the decline in wage dispersion in Newfoundland, Saskatchewan and Alberta are the starkest interprovincial differences. We find that they are accounted for by the growth in the extractive resources sectors, which benefited less‐educated and younger workers the most. Increases in minimum wages since 2005 are found to be the main reason why wages at the very bottom grew more than those in the middle of the distribution.  相似文献

Despite the central role of trust in the organizational sciences, we know little about what makes people trust the organizations they work for. This paper examines the antecedents of employees' trust in their organizations drawing on survey data from over 600 European professional workers and managers. The results revealed direct as well as indirect relationships of both human resource (HR) practices and procedural justice with trust. The relationships of both HR practices and procedural justice with trust were partially mediated by perceptions of organizational trustworthiness (in terms of perceived ability and trustworthy intentions of the organization). Justice and HR practices were also found to interact such that justice forms a stronger predictor of trust in organizations when HR practices are less developed. In addition, employees' dispositional propensity to trust explained significant variance in employee trust in their organization, even when it was controlled in our analysis. The implications of these findings for research and practice are discussed.  相似文献

High-density urban living means that urban green spaces are important nodes of contact with nature. This study examines expected outcomes that motivate people to seek green spaces in urban settings. A sample of Swiss residents were presented with Shin, Kwon, Hammitt, and Kim's (2005 Shin, W., Kwon, H., Hammitt, W. and Kim, B. 2005. Urban forest park use and psychosocial outcomes: A case study in six cities across South Korea. Scandinavian Journal of Forest Research, 20(5): 441447. [Taylor & Francis Online], [Web of Science ®] [Google Scholar]) psychosocial outcomes scale and asked which activities they choose to undertake in nearby natural areas. The most important motivations for visiting nearby green spaces were related to restoration, with social bonding as a desirable side benefit. There were few observable differences between urban and rural residents and level of education attained. Older people are motivated to visit nearby green spaces by the wish to seek social contact while younger people are motivated by the wish to seek escape and to reflect. This study contributes to the understanding of the psychosocial outcomes that residents expect from engaging in an activity in an urban green space.  相似文献

Internationalization of emerging market multinationals is a recent phenomenon gaining importance in the global economy. This foreign expansion of a new breed of companies has challenged established theories and practices in the field of international business (Cuervo-Cazurra, 2007). This article addresses the issue of whether or not there is something to learn from these emerging market companies and their foreign expansion. Focusing on the international trajectories of four Brazilian multinationals (i.e., Odebrecht, Embraer, Stefanini, and Marcopolo), this study analyzes their strategies and managerial processes during and after the recent economic crisis with regards to internationalization. Our qualitative fieldwork suggests that the trajectories of these Brazilian multinationals are quite unstructured and evolve as a reaction to the opportunities they face in international markets. It seems all four companies in our sample shared a strong entrepreneurial spirit and a high motivation to expand their international operations despite the crisis and the obstacles they faced. Our findings and suggestions in terms of lessons learned should provide valuable implications for multinational managers from other emerging markets by providing a better understanding of how Brazilian multinationals expand internationally, deal with economic crisis, and manage relationships with local and foreign institutions.  相似文献

Using a sample of 149 firms from the UK and New Zealand, we extend previous research on the nature of contemporary marketing practices by Brodie et al. (1997) to examine the practice of e-Marketing in relation to other aspects of marketing. Analysis reveals four combinations of marketing practice. While one third of firms emphasize either a Traditional Transactional or Traditional Relational approach to their markets, another third practice e-Marketing in combination with Transaction and Database Marketing, and a final third integrate all of Transaction, Database, Interaction, Network and e-Marketing. The findings show that for most firms, the level of e-Marketing practice reflects the extent to which information technology plays either a reinforcing, enhancing or transforming role in the organisation.  相似文献

In the Netherlands auditors can be trained in a part-time educational track in which students combine working and studying or in a full-time educational track. The former training is relatively firm-specific whereas the latter training is relatively general. Applying human capital theory, we expect higher wage growth for full-time educated auditors than for dual-educated auditors. Furthermore, full-time educated auditors may have better outside options than part-time educated auditors. This may make it easier for them to switch employers than for the part-time educated auditors. The predictions on tenure and wages of differently educated auditors are supported by the estimation results in this paper. The part-time, dual track appears an important route for students from a lower socioeconomic background.  相似文献

Over the last decade, governments throughout eastern and southern Africa have increasingly used strategic reserves and/or marketing boards to influence grain market outcomes, yet little is known about how these activities are affecting grain markets. This article estimates the effects of the Food Reserve Agency (FRA) on maize market prices in production and consumption regions in Zambia using a vector autoregression model and monthly data from July 1996 through December 2008. In recent years, FRA has become the dominant buyer of smallholder maize in Zambia. Simulations show that FRA activities stabilized market prices throughout the July 1996–December 2008 study period and raised mean prices between July 2003 and December 2008 by 17–19%. The price raising effects of FRA policies have assisted surplus maize producers but adversely affected net buyers of maize in Zambia, namely urban consumers and the majority of the rural poor. The increase in maize price stability is unlikely to have had substantial welfare effects on poor households. In contrast, relatively wealthy producers are likely to have benefited from the higher average and more stable maize prices resulting from FRA policies.  相似文献

Alternative approaches to discrete working time choice in an AGE framework   总被引:1,自引:0,他引:1  
We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly incorporates a logit discrete-choice approach into an AGE framework. On the grounds of both calibration consistency and adequate accommodation of within-household interaction, we argue that the logit approach is preferable.  相似文献
