Oil price indexing is a peculiar feature of the natural gas markets in Germany and other European countries. It is closely linked to the existence of local monopolies (at least de facto) and of the so called "take-or-pay" (TOP) contracts. After discussing the relation between these features and...

The unprecedented access of firms to consumer level data facilitates more precisely targeted individual pricing. We study the incentives of a data broker to sell data about a segment of the market to three competing firms. The segment only includes a share of the consumers in the market around...

Using a model with switching costs it is shown that firms may have an incentive to set up a new firm supplying to the same market under quite general conditions. The new firm attracts some market share of the founding firm. The start up firm is thus an act of cannibalization. Moreover, entry of...

I find that current US's and EU's Antitrust laws -- in particular their "moderate"' leniency programmes that only reduce or at best cancel sanctions for price-fixing firms that self-report -- may make collusion enforceable even in one-shot competitive interactions, like Bertrand oligopolies and...

The decision over exports vs. foreign direct investment (FDI) is usually discussed in an extension of the so-called Melitz model where firms with heterogeneous costs compete in a monopolistically competitive industry. The present paper starts from a situation where a potential foreign entrant...

We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a high-demand and a low-demand market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria are...
