On theoretical grounds, monitoring of top executives by the (supervisory) board is expected to be value relevant. The empirical evidence is ambiguous and we analyze three non-competing explanations for this ambiguity: (i) The positive effect on firm value of board monitoring is hidden in stock...

Many studies estimate the impact of exposure to some quasi-experimental policy or event using a panel event study design. These models, as a generalized extension of 'difference-in-differences' or two-way fixed effect models, allow for dynamic lags and leads to the event of interest to be...

Using a unique longitudinal representative survey of both manufacturing and non-manufacturing businesses in the United States during the 1990's, I examine the incidence and intensity of organizational innovation and the factors associated with investments in organizational innovation. Past...

The literature has pointed to different causes to explain the productivity gap between Europe and United States in the last decades. This paper tests the hypothesis that the lower European productivity performance in comparison with the US can be explained not only by a lower level of corporate...

Teamwork in research has been on the rise and so has the size of R&D teams. This paper offers an explanation for increasing team size that we call the "racing against time" hypothesis: With innovation races more competitive globally, R&D firms need to finish research projects as quickly as...

The purpose of this study is to investigate the relationship between a firm's R&D expenditures considered as an investment in knowledge, and its productivity, looking at sectoral peculiarities which may emerge; to this end, we use a large unique longitudinal database consisting of 1,809 US and...

An important issue in the analysis of cross-sectional dependence which has received renewed interest in the past few years is the need for a better understanding of the extent and nature of such cross dependencies. In this paper we focus on measures of cross-sectional dependence and how such...

The paper links finance theory to labor economics and political economy in the context of migration and immigration policy. Most research treating the impact of immigration has focused on the consequences for employees as measured by wages, earnings, and employment. Less is known about the...

Do wealth shocks affect the health of the elderly in developed countries? The economic literature is skeptical about such effects which have so far only been found for poor retirees in poor countries. In this paper I show that wealth shocks also matter for the health of wealthy retirees in the...

This paper formulates a simple model of female labor force decisions which embeds an in-work benefit reform and explicitly allows for announcement and implementation effects. We explore several mechanisms through which women can respond to the announcement of a reform that increases in-work...
