This paper examines the evolution of market structure in emerging market banking systems during the 1990s. While significant bank consolidation has been taking place in these countries, reflected in a sharp decline in the number of banks, this process has not systematically been associated with...

Open banking facilitates data sharing consented by customers who generate the data, with a regulatory goal of promoting competition between traditional banks and challenger fintech entrants. We study lending market competition when sharing banks' customer data enables better borrower screening...

This paper evaluates the main measures that have been used to regulate the interconnection prices in the telecommunication sector. We show that many of the regulations that are applying the vast majority of countries have very little theoretical support, and we identify the restrictions that...

Mandatory network unbundling is perhaps one of the foremost topics in regulatory economics today. The concept has crucial importance in the deregulation of many previously regulated industries including telecommunications, gas, electricity and railroads. Moreover, the topic has emerged as one of...

The fundamental contribution of the paper is to contest the view that greater market contestability has non-negative effects on market performance. In a model where employees pose a threat of potential entry, we demonstrate that a reduction in barriers to entry causes no fall in industry price...

We analyze the incentives of internet service providers (ISPs) to break net neutrality by excluding internet applications competing with their own products, a typical example being the exclusion of VoIP applications by telecom companies offering internet and voice services. Exclusion is not a...

In the 1950s and 60s, Japanese and US antitrust authorities occassionally used the degree of concentration to regulate industries. Does regulating firms based on their market shares make theoretical sense? We set up a simple duopoly model with stochastic R&D activities to evaluate market share...

Consider a government tendering a facility, such as an airport or utility, where one bidder owns a competing facility. With a "standard auction", this "existing operator" bids above the auctioned facility's expected profit, as winning means being a monopolist instead of a duopolist. This auction...

Network shares and retail prices are not symmetric in the telecommunications market with multiple bottlenecks which give rise to new questions of access fee regulation. In this paper we consider a model with two types of asymmetry arising from different entry timing, i.e. a larger reputation for...
