In a duopoly market, aspiration levels express how much sellers want to earn given their expectations about the other's behavior. We augment the sellers' decision task by eliciting their profit aspiration. In a first experimental phase, whenever satisficing is not possible, sales choices, point...

Electronic coordination links markets at different locations that have initially been (partially) separated by transport costs. Rising competitive pressure should in turn affect incentives to differentiate products. In this paper investment decisions concerning transport cost reduction and...

Der Beitrag sollte verdeutlichen, dass sich seit den Pioniermodellen mit unvollständiger Information mittlerweile eine recht heterogene Klasse von Ansätzen etabliert hat, die sich unter alternativen Grundannahmen mit der Frage auseinandersetzen, ob Unternehmen angesichts diverser...

They accumulate capacity through costly investment, with capital acumulation dynamics being affected by an additive shock the mean and variance of which...

Die Kompetenzverteilung in Genossenschaften zwischen Mitgliedern und Genossenschaftsbetrieb führt zu einer Organisationsform zwischen Hierarchie und Wettbewerb. Sowohl Mitglieder als auch das Management erhalten Teile der Entscheidungsbefugnis. In dieser Arbeit wird gezeigt, dass die...
