To prevent possible abuse of market power, an antitrust agency can force merging firms to divest some of their assets. The divested assets can be sold via auction either to existing competitors or to a new entrant. Divestiture of assets extends the range of parameters when a merger satisfies a...

We study a voluntary pre-merger notification game under asymmetric information and characterize perfect Bayesian equilibria. It is shown that the equilibrium outcomes are similar to those when notification is compulsory. However, thanks to the signaling opportunity that arises when notification...

This paper provides a first attempt to understand how outcomes are determined by the standard institutions of merger control. In particular, we focus on the internationally standard 2-phase investigation structure and remedy negotiations of the form practiced by the EC. We find that there are...

This paper develops a signalling model to look at some effects of the inclusion of an efficiency defence in merger regulation. By incorporating Type I and Type II errors into the antitrust agency's pay-off function approval probabilities are endogenized. The agency can choose to use a fuzzy...

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...

This paper analyses tax competition between a unionised and a non-unionised country for the location of an outside firm. We show that unionisation offers an extra incentive for the government to attract a foreign competitor to a concentrated domestic market, in order to affect the behaviour of...

An important puzzle in corporate taxation is that effective tax rates have fallen significantly while tax revenue has simultaneously risen in most countries. Moreover, the gross profitability of firms seems to be lower in high-tax countries, even though standard models of international...

This paper analyzes measures that limit firms' profit shifting activities in a model that incorporates heterogeneous firm productivity and monopolistic competition. Such measures, e.g. thin capitalization rules, have become increasingly widespread as governments have reacted to growing profit...
