Thresholds defined on the level and change in the HHI (Herfindahl- Hirschmann Index) applied to market shares seem to be the main instrument to select notified mergers for investigation in both the EU and US. We question the use of such a selection rule in di?erentiated products industries. We...

Given that brands (products) are location specific in terms of coverage of retail stores, we allow consumers to have preferences over location and products to carry distribution costs, alongside preferences and costs over other observable and unobservable product characteristics. We embed these...

Price coordination can be very harmful for consumers. Yet, even if a cartel is proved to exist, and successful in enforcement, how do we estimate damages or price overcharges to consumers? We build a structural model of the Irish automobile market that avails of a crosssection of new cars and...

Using weekly spot and future commodity prices in Chicago and New York, we construct expected transportation rates for grain between these two cities, expected inventory levels in New York, and realized errors in the expectations of such variables. We incorporate these exogenous commodity market...

We incorporate previously omitted controls of external conditions in transportation and commodity markets into Porter’s (1983) analysis of industry demand, conduct and stability of the JEC railroad cartel. We estimate the equilibrium price path, non-parametrically, and find that the reaction...
