It is increasingly observable that in different industries competitors jointly acquire and share customer data. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such agreements and their welfare implications. In our model the...

It is increasingly observable that competitors in different industries share customer data, which can be used for targeted pricing. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such sharing and its ensuing welfare effects. We...

We investigate how firms' incentives to acquire customer data for targeted offers depend on its quality. A two-dimensional Hotelling model is proposed where consumers are heterogeneous both with respect to their locations and transportation cost parameters (flexibility). Firms have perfect data...

In late 2005, the German energy companies E.ON and Wintershall and Russian Gazprom reached an agreement to build a new huge pipeline Nord Stream through the Baltic Sea. This pipeline will provide Russia for the first time ever with the direct access to its Western European customers. This...

Ende 2005 vereinbarten die deutschen Energieunternehmen E.ON und Wintershall gemeinsam mit der russischen Gazprom eine neue Pipeline "Nord-Stream" zu bauen, mit der russisches Erdgas erstmalig direkt durch die Ostsee nach Deutschland geliefert werden kann. Diese Pipeline erhöht die Sicherheit...

We develop a dynamic model of strategic investment in a transnational pipeline system. In the absence of international contract enforcement, countries may distort investment in order to increase their bargaining power, resulting in overinvestment in expensive and underinvestment in cheap...
