In this paper, we examine how parental health affects children's development of personality traits and problem behavior. Based on a German mother-and-child data base, we draw on observed parental health shocks as a more exogenous source of health variation to identify these effects and control...

We examine how parental health shocks affect children's non-cognitive skills. Based on a German mother-and-child data base, we draw on significant changes in selfreported parental health as an exogenous source of health variation to identify effects on outcomes for children at ages of three and...

We examine the empirical relation between CO2 emissions per capita and GDP per capita during the period 1960-1996, using a panel of 100 countries. Relying on the nonparametric poolability test of Baltagi et al. (1996), we find evidence of structural stability of the relationship. We then specify...

R&D encompasses plenty of activities which are usually summarized under the terms of basic research, applied research and development. Although basic research is often associated with low appropriability it provides the fundamental basis for subsequent applied research and development....

We scrutinize the impact of international productivity gains (spillovers) induced by imports and exports on optimal tariffs. First, we solve a stylized 2x2 trade model of a large open economy and show that (a) productivity gains via exports and imports both reduce the strategically optimal...

Assar Lindbeck has pointed to the problem that generous welfare state institutions may in the long-run undermine those social norms which limit the costs and incentives effects of the welfare state and thus guarantee its viability. This study is the first to assess the empirical validity of...

Inventors often experience a low productivity after their company has been subject to a merger or acquisition (M&As). It is of central managerial interest to identify factors facilitating the integration of new inventive staff and thereby counteracting innovation declines after M&As. This paper...

This paper provides a labour supply explanation to the observation that in Germany employment changes are asymmetric during the business cycle. Employment increases are slower, because the reservation wage of workers increases in times of job uncertainty. Workers are afraid in those periods of...

Based on a large data set containing information on occupations between 1979 and 1999, this study explores the ?black box? surrounding the skill?biased technological change hypothesis by analyzing the mechanisms that induce information technologies to be complementary to employees with higher...
