Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of drawing and shifting curves in the plane and is,...

Der Preisanpassungsprozess im Oligopol wird untersucht. Unter recht allgemeinen Voraussetzungen an die (lineare) Preis-Nachfrage-Funktionen der Akteure werden verschiedene Strategien diskutiert, wie z. B. die klassische Cournot-Nash-Lösung, die Launhardt-Hotelling-Strategie, die Stackelbergsche...

We study a Hotelling’s duopoly in world cotton market to examine the effects of Precision Agriculture’s (PA) adoption in term of strategic international trade between the United-States and Central and West Africa (CWA). We prove that US producers should be well advised to adopt PA to offer...

We analyze welfare maximizing monetary policy in a dynamic two-country model with price stickiness and imperfect competition. In this context, a typical terms of trade externality affects policy interaction between independent monetary authorities. Unlike the existing literature, we remain...

In their model of network formation, Berninghaus et al. (Exp Econ 9:237–251, <CitationRef CitationID="CR7">2006</CitationRef>; J Evol Econ 17:317–347, <CitationRef CitationID="CR8">2007</CitationRef>) showed that a periphery-sponsored star network is a strict Nash equilibrium. To examine the validity of their result, they also performed a laboratory experiment with human...</citationref></citationref>

This article analyses the ability of the learning firms in a Cournot oligopoly to discover market solutions more collusive that the Cournot equilibrium (CE). We start from the results of Vallée and Yıldızoğlu (J Econ Behav Organ 72:670–690, <CitationRef CitationID="CR11">2009</CitationRef>) and of Alós-Ferrer (Int J Ind Organ...</citationref>

We use a dynamic game model of a two-country monetary union to study the impacts of an exogenous fall in aggregate demand, the resulting increase in public debt, and the consequences of a sovereign debt haircut for a member country or bloc of the union. Two different scenarios for such a haircut...

We consider a supply chain with a single supplier and two retailers. The retailers choose their orders strategically, and if their orders exceed the supplier's capacity, quantities are allocated proportionally to the orders. We experimentally study the capacity allocation game using subjects...

In this paper, we introduce a generalized version of impulse balance equilibrium. The stationary concept is applied to 3 × 3 games based on the Bailiff and Poacher Game (Selten, 1991) and its predictive success is experimentally tested against the one of Nash equilibrium. Experiments with 26...
