In this paper a model, based on the nested multinomial logit model, is used to analyze airport competition and airline competition in a multiple airport region. It is shown that if the frequency elasticity of demand is smaller than 1, airfare-frequency and airport tax equilibria exist and are...

We extend the models in ("Competition in two-sided markets" of Armstrong (2006, Rand Journal of Economics) by adding within-group externalities.

Policy makers are increasingly concerned about the combination of market power and massive data collection in digital markets. This concern is fueled by the theoretical prediction that more market power causes firms to collect ever more data from their users. We investigate the relationship...

This report presents new evidence on industry concentration trends in Europe and in North America. It uses two novel data sources: representative firm-level concentration measures from the OECD MultiProd project, and business-group-level concentration measures using matched...

The main purpose of this paper is to calculate the effective total factor productivity (ETFP) of the Brazilian agricultural and industrial sectors during 1990-2009. The results are the following: all sectors have reached high ETFPs, with a few exceptions; however, the ETFPs have not mobilized...

This paper empirically analyzes the effects of a second generation rent control. We make use of an uncommon policy intervention in the German housing market and translate the generated variation into a difference-and-differences setup, augmented with elements of a discontinuity design, to...
