Abstract This paper investigates the existence of a possible media bias by analyzing the impact of automobile manufacturers’ advertisements on automobile reviews in a leading German car magazine. By accounting for both endogeneity and sample selection using a two-step procedure, we find a...

We use a rich longitudinal data set for West Germany to disentangle the wage effects for female workers around first birth. Data on daily real wages reveal a dip in women's real wages shortly before giving birth and a drop of 10 to 20 percent after finishing maternity leave and returning to the...

Does trade openness cause higher GDP per capita? Since the seminal instrumental variables (IV) estimates of Frankel and Romer [F&R](1999) important doubts have surfaced. Is the correlation spurious and driven by omitted geographical and institutional variables? In this paper, we generalize F&R's...

We investigate the effect of Europe's largest multilateral subsidy program for R&D-performing, small and medium-sized enterprises on firm growth. The program was organized under a specific budget allocation rule, referred to as Virtual Common Pot (VCP), which is designed to avoid...

The documented historical rise in female labour force participation has flattened in recent decades, but the proportion of mothers working full-time has steadily increased. We provide the first empirical evidence that the increase in mothers' working hours is amplified through the influence of...

Does U.S. military aid make the United States safer? To answer this question, we collect data on 173 countries between 1968 and 2014. Exploiting quasi-random variation in the global patterns of U.S. military aid, our paper is the first to provide causal estimates of the effect of U.S. military...

We develop the case of two-stage least squares estimation (2SLS) in the general framework of Athey et al. (Generalized Random Forests, Annals of Statistics, Vol. 47, 2019) and provide a software implementation for R and C++. We use the method to revisit the classic application of instrumental...
