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...

This paper shows how sustainable consumption patterns can spread within a population viaprocesses of social learning even though a strong individual learning bias may favorenvironmentally harmful products. We present a model depicting how the biased transmission ofdifferent behaviors via...

Interdependencies in consumer behavior stem from either status-seeking consumption orcompliance with social norms. This paper analyzes how a consumption act changes froma means to signal the consumer’s status to a means of norm compliance. It is shown thatsuch a transformation can only be...

Behavioral (e.g. consumption) patterns of boundedly rational agents can lead these agents intolearning dynamics that appear to be “wasteful” in terms of well-being or welfare. Within settingsdisplaying preference endogeneity, it is however still unclear how to conceptualize well-being.This...

In order to explain the growth of obesity in industrialized and transitioneconomies, a behavioral approach to food intake and overconsumption of caloriesis presented. It is argued that changes in food consumption patterns are one of themain drivers behind the imbalance of calories consumed and...

We analyze the stability and dynamics of an overlapping generations model with imperfectlycompetitive labour markets...

This paper extends the class of stochastic AK growth models with a closed-formsolution to the case where there are two capital goods in the model. To be precise,we consider the Uzawa-Lucas model of endogenous growth with human and physical capital. The extension holds, even if an external effect...

We study aggregative games in which players’ strategy sets areconvex intervals of the real line and (not necessarily differentiable)payoffs depend only on a player’s own strategy and the sum of allplayers’ strategies. We give sufficient conditions on each player’s payofffunction to...

In the standard CAPM with a riskless asset we give a simple proof of existence of equilibria without assuming concavity of the investor's utility functions. Moreover, we give a uniqueness result using assumptions on the risk aversion of investors.

Markowitz and Sharpe won the Nobel Prize in Economics more than a decade ago for the development of Mean-Variance analysis and the Capital Asset Pricing Model (CAPM). In the year2002, Kahneman won the Nobel Prize in Economics for the development of Prospect Theory....
