This paper estimates a theory-guided gravity equation of regional patient flows. In our model, a patient's choice to consult a physician in a particular region depends on a measure of spatial accessibility that accounts for the exact locations of both patients and physicians. Introducing this...

A striking pattern in transaction-level data is the concentration of international shipments in the hands of a few large firms. One common feature of dominating high-performance firms is that they produce multiple products and ship them to many destinations. Motivated by the emergence of highly...

This paper investigates the effects of mergers on the product mix of multiproduct firms. Thus, we open the black box of post-merger efficiency improvements to reveal a new margin of adjustment along the product dimension. We analyze horizontal mergers in a theoretical model where oligopolistic...

Motivated by the European Union's debate on sanctioning crude oil imports from Russia, we estimate the elasticity of substitution between different crude oil types. Using European data on country-level crude oil imports by field of origin, we argue that crude oil is not a homogenous good and...

We use the most recent wave of the German Qualifications and Career Survey and reveal a substantial wage premium in a Mincer regression for workers performing their job from home. The premium persists within narrowly defined jobs and after controlling for workplace activities and accounts to...

High-performance firms typically have two features in common: i) they produce in more than one country and ii) they produce more than one product. In this paper, we analyze the internationalization strategies of multi-product firms at the product-level. We find that the most productive firms...

We address the mismatch between existing theoretical models and standard empirical practice in the analysis of the labor market effects of offshoring. While theory focuses on one-sector or two-sector models, empirical studies exploit variation in offshoring across a large number of industries,...

This paper reveals a new determinant of wage markdowns at the firm level, namely, the product scope. Using matched employer-employee data on Danish manufacturing firms, we document a negative elasticity between wages and firm scope, which is of a similar magnitude but opposite sign as the...
