In US vaccine markets, competing producers with high fixed, sunk costs face relatively concentrated demand. The resulting price and quality competition leads to the exit of all but one or very few producers per vaccine. Our empirical analysis of exits from US vaccine markets supports the...

The Mexican banking sector experienced a process of liberalization which aimed towards increasing the level of competition and efficiency. This paper studies the evolution of the efficiency of the Mexican banking sector from 2002 to 2012 and also analyses its relationship with the degree of...

This paper rigorously investigates the determinants of bank competition for 146 countries over the sample period 1999–2011. The results employing both the Lerner index and the Boone indicator, reveal the distinctive characteristics of the competition drivers across different income groups of...

Many studies have attempted to investigate the determinants and implications of competition in the banking industry. The literature on the measurement of competition can be divided between the structural and non-structural approaches. The structural approach infers the degree of competition from...

Cross-country variability in regulatory frameworks, industrial policy, physician/pharmacy autonomy, brand/generic distinctions, and in the practice of medicine contributes to ambiguous interpretations of pharmaceutical cost comparisons. Here we report cross-country comparisons that: (i) focus on...

We examine the impact of bank competition and institutional factors on net firm entry in a sample of European manufacturing industries over the 1995-2006 period. Taking into account industry differences in the need for external finance, we find that bank competition helps firm entry. In...

Casual empiricism suggests higher quality is associated with greater variety. However, recent theoretical and empirical research has either not considered this link, or has been unable to establish unambiguous predictions about the relationship between quality and variety. In this paper we...

In media markets, products are highly differentiated but prices are often bunched at apparent focal points. I use a comprehensive cross-section data set on the German book market to assess whether such focal points are a result of upstream coordination and whether the option to impose resale...

This paper identifies patterns of cross-sectional and temporal price dispersion-in the Spanish online grocery retail market-and evaluates the extent to which search costs and chain heterogeneity explain such dispersion. We build a data set comprising 836,074 prices for the most popular grocery...

This paper studies regulatory policy interventions aimed at protecting vulnerable consumers who are disengaged and thus exposed to exploitation. We model heterogeneous consumer switching costs alongside asymmetric market shares. This setting encompasses many markets in which established rms are...
