Persistent shifts in equilibria are likely to arise in oligopolistic markets and may be detrimental to the measurement of conduct, related markups and intensity of competition. We develop a cointegrated VAR (vector autoregression) based approach to detect long-run changes in conduct when data...

Intertemporal shifts in conduct, such as a transition from competitive to anticompetitive behavior, induce shifts in the firms' equilibrium price configurations. Such shifts generate non-stationary price dynamics in addition to those which originate from exogenous fundamentals. We exploit this...

A central motivating factor for studying price markups is their effect on consumer welfare. Reported estimates of (firm-level) price markups in the literature, however, are often focused on industry or cross-country comparisons. These treat different industries equally rather than based on how...

Recent empirical studies suggest that there is a rising trend of market power across sectors in advanced economies. We contribute to this line of research by providing industry-specific evidence for German manufacturing industries, based on representative high-quality firm level data from...

In Westdeutschland ging die durchschnittliche Betriebsgroße in den 1990er Jahren zurück und begann in den späten 2000er Jahren wieder zu steigen, während die Betriebsgrößenlohnprämie umgekehrt dazu verlief. In diesem Papier zeigen wir, dass diese beiden Entwicklungen miteinander...
