We compute average mark-ups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions the results, with annual data for a set of 14 OECD countries covering the period 1970-2007, show...

This paper studies household inequality and product market power in dynamic, general equilibrium. In our model, households' price elasticities of demand endogenously vary with wealth. Heterogeneous firms set their price as oligopolistic competitors given the endogenous distribution of demand. A...

We document the decline in market power of the U.K. in safe assets and quantify the resulting losses. We estimate an increasing elasticity of demand for U.K. public debt during the latter half of the 20th century. This is in sharp contrast to the U.S., which displays the opposite pattern with...

Dieser Beitrag thematisiert die ökonomische Macht von Unternehmen in Österreich und stellt die Frage, ob diese - wie auch in anderen OECD-Ländern - zugenommen hat. Konzeptuell wird eine neuartige Differenzierung zwischen ökonomischer und politischer Macht sowie zwischen Marktmacht im engeren...

In April 2003 the U.S. Federal Energy Regulatory Commission proposed a complicated marketdesign – the Wholesale Power Market Platform (WPMP) – for common adoption byall U.S. wholesale power markets. Versions of the WPMP have been implemented in NewEngland, New York, the mid-Atlantic states,...

Präferenzen für Gütervielfalt und hieraus resultierende heterogene Preisbildung auf unvollkommenen Gütermärkten werden in empirischen Produktivitätsuntersuchungen bislang nur unzureichend berücksichtigt. Der vorliegende Beitrag möchte zur Schließung dieser Forschungslücke beitragen: Er...

Der angekündigte mehrheitliche Verkauf des Discounters "Plus" würde der Konzentration im deutschen Einzelhandel einen neuen Schub verleihen. Die oft vorgebrachte These, dass ein Ausscheiden kleinerer Wettbewerber langfristig auch den Konsumenten schadet, ist allerdings rein spekulativ. Dieser...

We evaluate behavior-based price discrimination from an antitrust perspective by focusing on an industry with inherited market dominance. Under horizontal differentiation behavior-based pricing does not by itself lead to persistence of dominance unless the dominant firm is protected by...

In this thesis, I have examined whether the current approach to competition policy is suitable for the distinct characteristics of the digital economy. It is particularly difficult to define the relevant market and rely on market share test as a proxy for market power in the digital economy...

"Two-sided" markets have two different groups of customers that businesses have to get on board to succeed - there is a "chicken-and-egg" problem that needs to be solved. These industries range from dating clubs (men and women), to video game consoles (game developers and users), to credit cards...
