Theoretically and experimentally, we generalize the analysis of acquiringa company (Samuelson and Bazerman 1985) by allowing for competition ofboth, buyers and sellers. Naivety of both is related to the idea that higherprices exclude worse qualities. While competition of naive buyers...

We analyze the impact of a uniform price cap at electricity spot markets on firms investmentdecisions and on welfare. Since investment decisions for those markets are taken in the longrun, fluctuating demand at the spot market eventually gives rise to high price spikes in case ofbinding...

To reduce the competition from farmers who self-produce seed, an inbred line seed producercan switch to nondurable hybrid seed. In a two-period model we investigate the impactof crop durability on self-production, pricing and switching decisions, and we examine theimpact of license fees paid by...

Recent research has led to the empirical regularity that rm growth rate distributionsare heavy tailed. This nding implies that a few rms experience spectaculargrowth rates and decline, but that most rms have marginal growth rates. The literatureon high growth rms shows that high growth rms are...

We propose a framework for analyzing transformations of demand. Such transformations frequently stem from changes in the dispersion of consumers` valuations, which lead to rotations of the demand curve. In a wide variety of settings, profits are a U-shaped function of dispersion. A high level of...

Firms selling multiple quality-differentiated products frequently alter theirproduct lines when a competitor enters the market. We present a model of multiproductmonopoly and duopoly using a general “upgrades” approach that yields a powerfulanalytical framework. We provide a simple...

This paper measures the extent to which prices exceed marginal costs in the U.S. natural gas distributionmarket during the period 1991-2007. We find large departures from marginal cost pricing in all 50states, with residential and commercial customers facing average markups of over 40%. Based...

This paper explores the macroeconomic consequences of preferences displaying asubsistence point. It departs from the existing related literature by assuming thatsubsistence points are specific to each variety of goods rather than to the compositeconsumption good. We show that this simple feature...

Der entwicklungsökonomische Diskurs ist aktuell geprägt durch eine kontroverseDebatte zwischen Jeffrey Sachs und William Easterly. Der Beitrag rekonstruiert beide Ansätze aus ordonomischer Perspektive. Er argumentiert, dass eine auf Kooperation angelegte Semantik vergleichsweise besser...
