Dieser Beitrag fasst die Ergebnisse unserer industrieökonomischen, theoretischen Forschung zur Fragestellung von Stabilität und Wandel von Arbeitsmarktinstitutionen zusammen. Wir verfolgen dabei einen wettbewerbsökonomischen Forschungsansatz, der Marktmacht sowohl auf Arbeits- als auch auf...

"This contribution gives an overview of the main results of our theoretical research on the stability and change of labour market institutions. We use so-called models of unionised oligopolies which are borrowed from the theory of industrial organization in order to analyse the effects of...

This paper analyses the extent of inter-format retail competition between supermarkets, discounters and drugstores in Germany, using data from the German market for diapers. We estimate a random coefficient logit model at the individual household level. Based on consumer substitution patterns,...
