This paper analyses the Relative Age Effect (RAE) in German elite youth soccer academies. We examine the efficiency of talent selection and the returns to training. Our results indicate a strong effect of players' birth dates on their probability of getting selected - and, thus, a waste of...

Crinò and Epifani (2012) report and discuss two empirical regularities they find in a representative sample of Italian manufacturing firms. First, there is a negative correlation between firms' productivity and their export share to low-income destinations. Second, there is a negative...

This paper uses a unique newly constructed data set to investigate for the first time the link between credit constraints and the extensive margins of exports in Germany, one of the leading actors on the international market for goods. In line with theoretical considerations and comparable...

Feenstra and Ma (2008) develop a monopolistic competition model where firms choose their optimal product scope by balancing the profits from a new variety against the costs of "cannibalizing" sales of existing varieties. While more productive firms always have a higher market share, there is no...

This study uses tailor made enterprise level data from various sources for firms from manufacturing industries to test for the link between credit constraints, measured by a credit rating score provided by a leading credit rating agency, and imports in Germany for the first time. We find...

In this article, I analyze whether German gasoline stations passed on the gasoline tax reduction to consumers. I use a difference-in-differences approach with France as the control group, as well as data for all countries in the European Union. The German fuel discount was in effect from June to...

Do we have effective competition between the gasoline's big five oligopolists (Aral, Shell, Esso, Total and Jet) and fringe gasoline stations? Using 2014 Market Transparency price data from 66 cities with populations between 60,000 and 100,000, we analyze which brands lead price increases, the...

This paper uses information on export transactions by German firms from 2011 to document the role of characteristics of destination countries for export scope, where export scope is defined as the number of different products a firm exports to a destination market. It demonstrates that in line...
