We suggest a simple asset market model in which we analyze competitive and strategic behavior simultaneously. If two-fund separation is found to hold across periods for competitive behavior, it also holds for strategic behavior. In this case the relative prices of the assets do not depend on...

We explain excess volatility, short-term momentum and long-term reversal of asset prices by a repeated game version of Keynes beauty contest. In every period the players can either place a buy or sell order on the asset market. The actual price movement is determined by average market orders and...

We present two new notions of evolutionary stability, the trulyevolutionarily stable state (TESS) and the generalized evolutionarilystable equilibrium (GESE). The GESE generalizes the evolutionar-ily stable equilibrium (ESE) of Joosten [1996]. An ESE attracts allnearby trajectories...

A common feature of the literature on the evolution of preferencesis that evolution favors nonmaterialistic preferences only if preferencetypes are observable at least to some degree. We argue that this resultis due to the assumption that in each state of the evolutionary dynam-ics some Bayesian...

We study the nature of dominance violations in three minimalist dominance-solvable guessing games, featuring two or three players choosing among two or three strategies. We examine how subjects’ reported reasoning translates into their choices and beliefs about others’ choices, and how...

In a public goods experiment, subjects can vary over a period of stochasticlength two contribution levels: one is publicly observable (their cheap talkstated intention), while the other is not seen by the others (their secretintention). When the period suddenly stops, participants are restricted...

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 deals with the introduction of stock options in an (dy-namically) incomplete securities market.

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...

Many decisions in economics and finance have to be made under severe time pressure. Furthermore, payoffs frequently depend on the speed of decision-making, like, for instance, when buying and selling stocks. In this paper, we examine the influence of time pressure and time-dependent incentive...
