We propose a representation of individual preferences with a subsistence requirement in consumption, and examine its implications for substitutability and sustainability. Specifically, we generalize the standard constant-elasticity-of-substitution (CES) utility specification for manufactured...

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...

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...

This paper builds a consumer search model where the cost of going back to stores already searched is explicitly taken into account. We show that the optimal search rule under costly recall is very different from the optimal search rule under perfect recall. Under costly recall, the optimal...

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

This article relates agents' learning of a preference for a technology, competition of technologies, and their relative diffusion among potential adopters. Competitive interactions between two technologies are captured by an extended Lotka–Volterra model. To also incorporate preference...

We propose a novel approach to model joint consumption decisions of individuals who care for each other. We assume non-cooperative interaction between the different individuals and the within-group consumption outcome critically depends on the degree of caring between the group members. By...

We propose a method to quantify other-regarding preferences in group decisions. Our method is based on revealed preference theory. It measures willingness-to- pay for others’ consumption and willingness-to-pay for equality in consumption by evaluating consumption externalities in monetary...
