In current horizontal merger policy in the US and the EU an explicit efficiency defense is allowed. On both sides of the Atlantic mergers are unconditionally approved if internal efficiencies are sufficient to reverse the mergers’ potential to harm consumers in the relevant market. Current...

We compare the prevailing system of compulsory pre-merger notification with the Australian system of voluntary pre-merger notification. It is shown that, for a non-trivial set of parameter values, a perfect Bayesian equilibrium exists in mixed strategies in which the regulator investigates...

We review the enforcement of competition policy and the activities of Turkish Competition Authority during 1997-2000. Descriptive statistics are provided on the caseload handled, such as types of anti-competitive behavior investigated, breakdown of investigations by industry, violations found,...

We analyze a model where an antitrust authority delegates to an audit inspector the mission of gathering the sufficient information to condemn a cartel. The authority has two instruments at her disposal: rewarding the inspector with a proportion of the collected fine or providing him with...

The effect of competition among self-regulatory organizations (SRO) on the efficiency of the corresponding goods and services markets is considered. It is shown that under certain conditions the competition among SRO worsens the quality of the goods and services and leads to decrease in...

The ongoing restructuring of the electricity sectors in many countries raises the policy question of to what extent the public generating assets should be privatized and what the objective function of any remaining public generation companies should be. We analyze the optimal regulatory policy...

This paper looks at competition in the Telecommunications industry with non-linear tariffs and network based price discrimination. Allowing for asymmetric networks and non-cooperatively chosen access prices simultaneously allows to explicitly derive non-reciprocal equilibrium access price...

The EU regulatory framework for electronic communications services distinguishes between markets that are susceptible to ex ante regulation and those that are subject to competition law alone. The paper lays out the methodology for identifying relevant markets that may be considered for ex ante...

This article discusses changes in the U.S. telecommunications market over the last decade and argues that increasing competitive substitution from wireless and internetbased communications has undermined the rationale for conventional monopoly regulation of incumbent local telephone carriers....
