We study contestability in non-profit markets when non-commercial providers supply a homogeneous collective good through increasing-returns-to-scale technologies. Unlike in the case of for-profit competition, in the non-profit case the absence of price-based sales contracts means that fixed...

Google wird häufig als marktmächtig bezeichnet. Grund dafür ist ein mutmaßlicher Marktanteil von über 90% in manchen Ländern. Eine gründliche Marktabgrenzung im wettbewerbsrechtlichen Sinne liegt dieser Aussage aber nicht zugrunde. Was umfasst den 'Suchmarkt'? Wird z.B. zwischen Produkt-,...

We experimentally examine the effects of price competition in markets for expe-rience goods where sellers can build up reputations for quality. We compare price competition to monopolistic markets and markets where prices are exogenously fixed (somewhere between the endogenous oligopoly and...

Seit Mai 2007 veröffentlicht die Europäische Zentralbank (EZB) einen experimentellen Index für die Entwicklung administrierter Preise im Euro-Währungsgebiet. Damit hat die EZB ein neues interessantes Instrument für die Konjunkturanalyse bereitgestellt. Der Index erfasst die Preisentwicklung...

On average, for an export-active firm, one-off events generate 17 % of foreign sales. These patterns do not sit well with available trade models. To reconcile theory with the...

This paper uses a unique representative firm level data set to analyse the effect of domestic and international competitive pressure and ownership changes in three emerging economies, Bulgaria Poland and Romania. Our main findings can be summarized as follows: Domestic competitive pressure,...

This paper explores an equilibrium model for industry entry dynamics and technological change. We focus on the share valuation of firms in the transition as technology changes, and whether or not share prices are always increasing when technology improves. We find that there can be a U-shaped...

The disclosure requirements for firms issuing equity on German crowdinvestingplatforms are quite lax at the moment. This paper states that this loose requirement policy is not optimal in the presence of competition among platforms. First, a simple three-staged theoretical model is derived to...

On crowdinvesting-platforms, non-publicly traded companies can offer equity to private investors. Currently, platforms like Crowdcube.com in Great Britain or Seedmatch.de in Germany are using a mechanism for the allocation of available shares best described by the phrase first come, first...

We discuss the benefits of net neutrality regulation in the context of a two-sided market model in which platforms sell Internet access services to consumers and may set fees to content and applications providers on the other side of the Internet. When access is monopolized, we find that...
