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...

This paper shows that self-employment opportunities shape the market power of employers in low-income countries, with implications for industrial development. Using data from Peru, we document substantial employer concentration and high self-employment rates across manufacturing local labor...

Anonymous and unannounced site inspections known as "Mystery Shopping" (MS) are common in multi-site service firms, but little is known about the strategic importance of this practice. We conceptualize MS as a monitoring tool firms use to implement the optimal allocation of site resources...

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...

This paper uses basic empirical facts from attention and perception psychology for a behavioral approach to equilibrium analysis at the industry and the macroeconomic level. The paper endogenously determines whether an economy is information-rich and whether scarcity of attention complements...

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...

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;...

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...

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...

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...
