In its landmark ruling in Illinois Brick Co. v. Illinois in 1977, the U.S. Supreme Court restricted standing to sue for recovery of antitrust damages to direct purchasers. However, antitrust damages are typically (in part) passed on to intermediaries lower in the chain of production and...

In positive expectations feedback experiments, however, convergence to the equilibrium price tends...</p></a>

We present a dynamic model of the interaction between interest groupsand policymakers, featuringendogenous interest group formation. We show that complicated dynamicpatterns in economicpolicies may arise once interest group formation is taken intoaccount.

This discussion paper resulted in a publication in <I>Games and Economic Behavior</I> (2014). Volume 86, pages 77-95.<P> Minority games are a stylized description of strategic situations with both coordination and competition. These games are widely studied using either simulations or laboratory...</p></i>

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that the presence of these interest groups increases the winning set, which is the set of policy platforms for the challenger that will defeat the incumbent. Therefore interest...

We study participation games with negative feedback, i.e. games where players choose either to participate in a certain project or not and where the payoff for participating decreases in the number of participating players. We use the replicator dynamics to model the competition between...

We show that, by coordinating voting behavior,these interest groups increase the winning set, which...</p></a>

This paper introduces the Werden-Froeb Index (WFI) to assist in evaluating merger-specific efficiencies in horizontal mergers. The index measures the weighted average reduction in marginal costs required to restore pre-merger equilibrium prices and quantities after the (full or partial) merger...

We investigate expectation formation in a controlled experimental en-vironment. Subjects are asked to predict the price in a standard asset pricingmodel. They do not have knowledge of the underlying market equilibrium equa-tions, but they know all past realized prices and their own predictions....

This discussion paper led to a publication in the <I>Journal of Economic Dynamics & Control</I>. Volume 36(8), pp. 1101-1120.<P> Recent studies suggest that the type of strategic environment or expectation feedback can have a large impact on whether the market can learn the rational fundamental price.
