Policy analysis frequently requires estimates of aggregate (or mean) consumer elasticities. However, estimates are often made incorrectly, based on elasticity calculations at mean income. We provide in this paper an overall integrated analytical framework that encompasses these biases and...

A decision maker (DM) makes choices from different sets of alternatives. The DM is initially fully ignorant of the payoff associated to each alternative, and learns these payoffs only after a large number of choices have been made. We show that, in the presence of an outside option once payoffs...

A framework is proposed for organizing phenomena related to the (mis)prediction of utility, in particular neglecting adaptation. A categorization is introduced that accounts for asymmetries in misprediction. In decision-making, goods and activities satisfying extrinsic desires are more salient...

The relationship income / distance to CBD is basically nonlinear and its form varies a lot across the world. We often consider classic forms such as the typical US city one, where rich people live in the suburbs and the European city where they live downtown. Nevertheless, more complex patterns...

In dynamic resource allocation models, the non-existence of voting equilibria is a generic phenomenon due to the multi-dimensionality of the choice space even with agents heterogeneous only in their discount factors. Nevertheless, at each point of time there may exist a "median voter" whose...

In diesem Jahr wurde der in Princeton lehrende, britisch-amerikanische Ökonom Angus Deaton mit dem Nobelpreis für Wirtschaftswissenschaften ausgezeichnet. Es werden damit - wie es in der offi ziellen Verlautbarung des Nobelpreiskomitees heißt - seine Analysen von Konsum, Armut und Wohlfahrt...

This paper provides an introduction to the field of evolutionary economics with emphasis on the evolutionary theory of household behavior. It shows that the goal of evolutionary economics is to improve upon neoclassical economics by incorporating more realistic and empirically grounded...

By revisiting Scitovsky's work on well-being, which introduces 'novelty' into the consumer's option set as a peculiar source of satisfaction, this paper finds a number of connections with the recent behavioural economics so as to open new lines on inquiry. First, similarly to behavioural...

This paper analyzes a boundedly rational decision maker who is uncertain about his preference and faces the following trade-off: adding a good to the choice set has a positive option value but increases the complexity of the choice problem. The increased complexity is modeled as a reduction of...

We demonstrate that interpersonal comparisons lead to keeping up with the Joneses-behavior. Using annual household data from the German Socio-Economic Panel, we estimate the causal effect of changes in reference consumption, defined as the consumption level of all households who are perceived to...
