Many consumption prices are highly volatile. It would certainly overburden our cognitive system to fully adjust to all these changes. Households therefore often rely on simple heuristics when deciding what to consume, e.g. in the form of a constant budget share for a specific consumption...

This paper adds to the literature on the crowding out effect of tobacco expenditure in two ways. Firstly, the paper uses expenditure data from a low income sub-Saharan African country, Zambia, where most households are poor. Secondly, unlike previous studies, we relax the exclusion restriction...

The act of choosing can influence maximizing behaviour for at least two distinct reasons: 1) process significance and 2) decisional inescapability. The constructive programme of the paper is combined with critical appraisal of the implications of these concerns for rational decisions about...

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...

In this note, we address nonparametric identification of a collective model of household behavior in the presence of additive unobserved heterogeneity in the sharing rule. We show that the (nonstochastic part of the) sharing rule is nonparametrically identified. Moreover, under independence...

Using a homogeneous and continuous utility function that represents a household's preferences, this paper proves explicit identities between most of the different objects that arise from the utility maximization and the expenditure minimization problems. The paper also outlines the homogeneity...

Behavioral economics is influencing regulatory initiatives in many nations, including the United States and the United Kingdom. The role of behavioral economics is likely to increase in the next generation, especially in light of the growing interest in low-cost, choice-preserving regulatory...
