mode of production exist that is based on the contributions of many software programmerswithout providing any direct monetary incentives for them? And how can these programmerscoordinate their actions without relying on either the guidance of the price mechanism or thedirection through a...

This paper reviews the Hotelling literature of product differentiation. The purpose of this work is to examine the impact of the market structure on price competitionand equilibrium differentiation. The existence of a general ’principle of differentiation’ is rejected. In contrast,...

This paper extends the standard Hotelling model with quadratic transport costs to the multi-firm case. Considering locational equilibria we show that neither holds the Principle of Maximum Differentiation - as in the duopoly model - nor does the Principle of Minimum Differentiation - as in the...

The common prior assumption justifies private beliefs as posterior probabilities when updatinga common prior based on individual information. Common priors are pervasive in most economicmodels of incomplete information and oligopoly models with asymmetrically informed firms. Wedispose of the...

The common prior assumption asserts that the beliefs of agents in different states of theworld are their posteriors based on a common prior and possibly some private signal. Commonpriors are pervasive in most economic models of incomplete information, oligopoly models withasymmetrically informed...

We introduce a generalized theoretical approach to study imitation andsubject it to rigorous experimental testing. In our theoretical analysiswe …nd that the different predictions of previous imitation models aredue to different informational assumptions, not to different behavioralrules. It is...

Dieser Beitrag erweitert die Standardmodellierung der Literatur über Informationsaustausch zwischen Unternehmen bei Nachfrageunsicherheit und läßt sich vor allem auf Unternehmen in neuen Branchen oder in unsicheren Märkten anwenden ...

Historical examples (ISDN, Teletex, telefax, telex) show us that forecasting efforts in the telecommunication sector can go awry - not only by a few percentage points but by large magnitudes. We maintain that with strong network effects it is not possible to forecast the success of...

This paper will present results of the surveys and new trends which were relatedto e-governmental issues. A common understanding of e-government isusage of ICT means in the public sector for delivering information and servicesto its customers and enterprises. The objective is improvement of...

We analyze the economic effects of a developer’s connectedness in the electronic gameindustry. Knowledge spillovers between developers should be of special relevance in this knowledgebasedindustry. We calculate measures for a developer’s connectedness to other developers atmultiple points in...
