Using U.S. NETS data, we present evidence that the positive trend observed in national product-market concentration between 1990 and 2014 becomes a negative trend when we focus on measures of local concentration. We document diverging trends for several geographic definitions of local markets....

We study the spatial expansion of banks in response to banking deregulation in the 1980s and 90s. During this period, large banks expanded rapidly, mostly by adding new branches in new locations, while many small banks exited. We document that large banks sorted into the densest markets, but...

To explain the spatial selection of vertically di fferentiated firms, this paper incorporates heterogeneous preferences and heterogeneous quality productions into a framework of the footloose capital model, in which labor is immobile. In two regions with identical population size, when trade...

The paper explores the analogy between city and two-sided market. It generalizes the results on the pricing strategies of the platform in the two-sided markets for the case when concentration spillover plays an important role. The two-sided market framework is applied to model a city. The paper...

Sustainable use of natural resources becomes an important issue today not only due to global warming and pollution issues but also because of critical pressure on the Earth's regeneration possibility. We cannot use classical microeconomic approach here for two reasons: a) impossibility to create...

The seaborne steam coal market changed in recent years. Trade volumes grew dynamically, important players emerged and since 2007 prices increased significantly and remained relatively high since then. In this paper we analyse market equilibria in the years 2006 and 2008 by testing for two...

In the homogenous good case, the relationship between market struc- ture and efficiency was studied extensively. Assuming a standard quadratic utility with quantity competition, this paper carries on the analysis in a differentiated good context. It can be shown that there is a positive re-...

We investigate the causal effect of market structure on market performance in the consumer electronics. We combine data from Austria's largest online site for price comparisons with retail data on wholesale prices provided by a major hardware producer for consumer electronics. We observe input...
