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,...

The optimal market structure in the mobile industry is an important topic in the mobile industry. In this paper, we use two theoretical frameworks and a structural estimation approach to assess the effects of market structure on consumer surplus in symmetric mobile markets. When mobile services...

In many industries, the number of firms evolves non-monotonically over time. A phase of rapid entry is followed by an industry shakeout: a large number of firms exit within a short period. We present a simple timing game of entry and exit with an exogenous technological process governing firm...

This paper studies the effect of non-compliance with a minimum quality standard on prices, quality, and welfare in a vertical differentiation model. Non-compliance with a minimum quality standard by a low-quality firm reduces quality levels of both firms, increases the price for the high-quality...

Consumers buy products even if they find it too time-consuming to evaluate products carefully. I present a simple market model with sequential consumer search and differentiated products in which consumers may purchase products without evaluation. In a market with evaluation cost heterogeneity...

We study research joint ventures (RJV) given that knowledge spillovers depend positively on the technological proximity between rms. Possible scenarios differ in the intensity of collaboration, i.e., the (non)coordination of research activities and the extent of knowledge sharing. The...

Inspired by recent regulations in the New York ICAP market, this paper examines the effect of price regulations on a multi-unit uniform price auction. General bid caps reduce the maximum price below the bid cap, but also the minimum potential market price below the cap. A bid cap only for the...

Price levels and movements on gasoline and diesel markets are heavily debated among consumers, policy-makers, and competition authorities alike. In this paper, we empirically investigate how and why price levels differ across gasoline stations in Germany, using eight months of data from a novel...

The recent development of 3D printing raises the issue of how to protect manufacturing firms from product piracy. In this paper, we are interested in potential regulatory requirements to protect firms from falling victim of product piracy and associated quality choices. We employ a...

The existence and persistence of large spatial disparities in un-employment within national economies is a central issue in regional economics. Previous empirical analyses have largely disregarded the role of fundamentals. On the contrary in this paper we explore the link between labour...
