This paper examines how delivery tariffs and private quality standards are determined in vertical relations that are subject to asymmetric information. We consider an infinitely repeated game where an upstream firm sells a product to a downstream firm. In each period, the firms negotiate a...

In this paper, we propose a probabilistic voter model that rationalizes the ineff cient use of labor input in municipality-owned enterprises. Our focus is on the relationship between absolute as well as relative ineff ciency measures and the size of the municipality in which public rms operate....

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first results is that export...

We analyze pricing and competition under paid prioritization within a model of interconnected internet service providers (ISPs), heterogeneous content providers (CPs) and heterogeneous consumers. We show that prioritization is welfare superior to a regime without prioritization (network...

We analyze a vertical structure with an upstream monopoly and two downstream retailers. Demand is uncertain but each retailer receives an informative private signal about the state of the demand. We construct an incentive compatible and ex ante balanced mechanism which induces the retailers to...

In den letzten Jahren haben sich die Telekommunikation (TK) und das Internet zu einem hoch innovativen Bereich entwickelt, der ein wichtiger Wachstumstreiber für die gesamte Volkswirtschaft werden kann. Eine Regulierung, die primär auf die Beschränkung marktmächtiger Unternehmen abzielt,...

Die von der Bundesregierung geplante Verschärfung der Preissetzungsregeln im Einzelhandel sieht vor, dass Einzelhändler Güter nicht mehr zu Preisen verkaufen dürfen, die unter den Einstandspreisen liegen. Eine solche Preispolitik ist schon heute unzulässig, wenn damit kleinere Konkurrenten...
