There is considerable evidence that producer-level churning contributes substantially to aggregate (industry) productivity growth, as more productive businesses displace less productive ones. However, this research has been limited by the fact that producer-level prices are typically unobserved;...

The main purpose of this paper is to provide a critical overview of the recent empirical contributions that use cross country data to study the effect of product market regulation and reform on a country's macroeconomic performance. After a brief review of the theoretical literature and of...

This paper provides evidence from a natural experiment on the importance of workers' tacit knowledge about firms' intangible assets for competition in product and labor markets. Evidence is presented on product and labor market imperfections across manufacturing and services firms in the...

We study how the threat of entry affects service quantity and quality of general practitioners (GPs). We leverage Germany's needs-based primary care planning system, in which the likelihood of new GPs reduces by 20 percentage points when primary care coverage exceeds a cut-off. We compile novel...

Using register data, we document that the average German labor market, defined by hires in combinations of 3-digit occupations, requirement levels, and commuting zones, is highly concentrated (HHI=0.257). By EU antitrust thresholds, 56 percent of these labor markets feature moderate or high...

Many start-ups chose to compete with incumbent firms using one of two generic strategies: cost leadership or differentiation. Our study demonstrates how this choice depends on whether the startup was founded out of necessity. Our results, based on a representative data set of 4,568 German...

We establish the existence of strong media slant against foreign owners. Using a unique data set from nation-wide distributed quality newspapers in Germany, we find that a foreign firm that downsizes in Germany receives almost twice as much attention than a domestic firm. This quantitative slant...

Our analysis of the survival of firms leads to the important result that the hypotheses about differences between various industries in the life duration of new firms and about the importance of the region of location for the probability of survival are confirmed. Many more enterprises are...

Medical providers often have a significant influence on treatment decisions which they can use in their own financial interest. Classical models of supplier-induced demand predict that medical providers will supply fewer services if they face increasing prices. We test this prediction based on a...

Strategy research often aims to empirically establish a causal relationship between an independent variable and a dependent variable such as firm performance. For many important strategy research questions, however, traditional empirical techniques are not sufficient to establish causal effects...
