The paper discusses the respective roles of competition policy and sector-specific regulation for industries such as telecommunications, electricity, and gas, in which network infrastructures that are natural monopolies serve as essential facilities for anybody who wants to provide services in...

We address one of the cardinal puzzles of European corporate law: the lack of derivate share-holder suits. We explain this phenomenon on the basis of percentage limits which require share-holders to hold a minimum amount of shares in order to bring a lawsuit. We show that, under this legal...

Anti-trust cases more often than not hinge upon market definition. The anti-trust authorities use standardised tests for the purpose, like the small but significant and nontransitory increase in price test prevalent in US law.

I study the incentives of oligopolists to acquire and disclose information on a common demand intercept. Since firms may fail to acquire information even when they invest in information acquisition, firms can credibly conceal unfavorable news while disclosing favorable news. Firms may earn...

This paper analyzes the impact vertical integration has on upstream collusion when the price of the input is linear. As a first step, the paper derives the collusive equilibrium that requires the lowest discount factor in the infinitely repeated game when one firm is vertically integrated. It...

By using general information structures and precision criteria based on the dispersion of conditional expectations, we study how oligopolists' information acquisition decisions may change the effects of information sharing on the consumer surplus. Sharing information about individual cost...
