We study the impact of research collaborations in coauthorship networks on total research output. Through the links in the collaboration network researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them. We characterize the interior...

Einkaufen in Internet, die Nutzung von sozialen Netzen oder Online- Banking gehören zum Alltag der Verbraucher in Deutschland. Das Thema Privatsphäre und Datenmissbrauch ist deshalb nahezu täglich in den Medien. Da ist es erstaunlich, dass fundiertes wissenschaftliches Wissen, wie Verbraucher...

Das digitale Wirtschafsleben ist geprägt von der nahezu täglichen Angabe persönlicher Informationen zu verschiedenen Zwecken. Die Entlohnung dafür findet auf unterschiedliche Weisen statt: durch Preisreduktion, Produkt-Personalisierung oder scheinbar freie Nutzung von Dienstleistungen im...

We take for granted that the basic choice in public policy is between allocation of resources by government bureaucracy, on the one hand, or allocation by markets, on the other. But that dichotomy is false, and at least under contemporary circumstances it is more accurate to describe the choice...

We consider price-fee competition in bilateral oligopolies with perfectly-divisible goods, non-expandable infrastructures, concentrated agents on both sides, and constant marginal costs. We define and characterize stable market outcomes. Buyers exclusively trade with the supplier with whom they...

In his 2012 article, “Revisiting the Revisionist History of Standard Oil”, Christopher Leslie takes issue with John McGee's work on predatory pricing and its influence on antitrust law and scholarship. Leslie claims McGee's analysis was methodologically flawed, ideologically motivated, but...

The aim of this work is to give a perspective about the utility of the strategic alliances from the view of three theories: The resource-based theory, the industry-based theory and the institutional-based theory. The raised hypotheses were that the strategic alliances are useful to enter to the...

This article characterises the commercial airline transport market in Colombia and then develops a reputation model describing the relationship between airlines and consumers. Grossman and Hart's pioneering work (1986) is thus used for modelling horizontal integration between firms and is then...

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....
