Sentiment and stock returns: The SAD anomaly revisited

Widely-cited research by Kamstra et al. (2003) argues that changes in mood resulting from Seasonal Affective Disorder (SAD) drive changes in investor risk aversion and cause seasonal patterns in aggregate stock returns around the world. In this paper we reexamine the so-called SAD effect by replicating and extending Kamstra et al. (2003). We study the psychological underpinnings of the SAD hypothesis and show that the time-series predictions of the SAD model do not correspond to the seasonal patterns in depression found in the general population. We also investigate the cross-sectional prediction that SAD has a greater effect on stock markets in countries where SAD is more prevalent and find no relation between the prevalence of SAD and stock returns. Finally, we document that the SAD effect is mechanically driven by an overlapping dummy-variable specification and higher returns around the turn of the year.     

Societal risks as seen by Chinese students living in Macao

The present study reports on mean risk magnitude judgements expressed by Chinese students living in Macao on 87 hazardous activities, substances and technologies. These judgements were compared with findings on African, American and European samples. Despite high similarity in mean results, standard deviations, and linear correlation with the other countries, Macao appears to be the country in which the level of risk perception was clearly the highest, and this seems largely due to five items connected with violence and crime. These results are explained by the exceptionally high level of crime in Macao and its crude display by the local media.     

The Spatial Range of Public Goods Revealed Through Referendum Voting

Billions of dollars are now spent annually in the United States and Europe for spatially delineated environmental services such as agricultural landscape management and river restoration programs, yet little is known about the spatial distribution of the benefits from these policies. This paper develops a framework for recovering information on this question from the spatial pattern of votes cast for referenda on the provision of spatially delineated public goods. We specify a model linking voter support for environmental improvement to the distance at which such improvements are expected to occur. The empirical application is to a river restoration referendum in the Swiss canton of Bern. Our results indicate that the benefits from river restoration have a strong local component, sufficiently strong that voter approval would not occur if only canton-wide benefits were at stake. Surprisingly, support for river restoration is no greater, and in some specifications is actually lower, in locations where rivers are a prominent feature in the environment.

Performance Measurement and Compensation Practices in Hospitals: An Empirical Analysis in Consideration of Ownership Types

Against the background of regulatory initiatives that put hospitals under increasing financial pressure, we explore performance measurement and compensation practices in hospitals through a multiple case study. We extend previous research by comparing practices among different ownership types (i.e. public, non-profit, and private) and by providing initial evidence on compensation schemes for the clinical staff. Our empirical investigation is embedded in the ‘stewardship–agency axis’ that allows the development of theoretical arguments about the interdependencies between ownership and performance measurement systems (PMS). We distinguish two primary levels of analysis – the types of measures implemented and their linkage with compensation and decision-making. Our findings suggest that the types of measures are primarily affected by regulatory pressures, while powerful internal actors considerably influence the linkage between these measures and compensation. Consistent with our theorised patterns, cross-case analyses indicate differences between ownership types concerning the performance dimensions that are prioritised and the linkage of performance measures with compensation of the clinical staff. Together, these findings provide evidence on the interdependent effects of the regulatory environment, the type of ownership and internal actors on a hospital's PMS. We also provide some tentative explanations for these findings based on insights from institutional and behavioural theory.     

Financing a Portfolio of Projects

This article shows that investors financing a portfolio of projectsmay use the depth of their financial pockets to overcome entrepreneurialincentive problems. Competition for scarce informed capitalat the refinancing stage strengthens investors' bargaining positions.And yet, entrepreneurs' incentives may be improved, becauseprojects funded by investors with "shallow pockets" must havenot only a positive net present value at the refinancing stage,but one that is higher than that of competing portfolio projects.Our article may help understand provisions used in venture capitalfinance that limit a fund'sinitial capital and make it difficultto add more capital once the initial venture capital fund israised.
