The objectives of this paper are to propose and to implement for the French case an approach for the estimation of consumers' willingness to pay for tap water quality. This method is indirect and is based on the observation of the households' demands for soft drinks and bottled water. The lack...

Although the effect of monetary sunk costs on decision-making is widely discussed, research is still fragmented, and results are sometimes controversial. One reason for this incomplete picture is the missing differentiation between the effect of sunk costs on utilization and progress decisions...

Nachdem eine Bargeldabschaffung schon vor längerem u.a. von Wissenschaftsvertretern wie Rogoff, Summers und Bofinger diskutiert und im Ergebnis befürwortet wurde, scheint das Thema aufgrund aktueller Entwicklungen sowie bereits vollzogener Maßnahmen verstärkt in Wissenschaft und Praxis...

In the tradition of Afriat (Int Econ Rev 8:67-77, 1967), Diewert (Rev Econ Stud 40:419-425, 1973) and Varian (Econometrica 50:945-972, 1982), we provide a revealed preference characterisation of exact linear aggregation. This guarantees that aggregate demand can be written as a function of...

We consider the interplay between income distribution and optimal commodity taxation, linking equity issues to optimal taxes through the effect of income distribution on market demand and its price elasticity. We find conditions to conciliate the equity and efficiency tradeoff and to assess the...

This paper develops a conceptual framework that can explain why economic development goes along with increases in body weight and obesity rates. We first introduce the concept of novelty consumption, which refers to an increase in food availability due to trade or innovation. Then we study how...

We study a broad class of dynamic consumer problems and characterize the short and long-run response of the demand for a good to a permanent increase in its market price. Such response can be non-monotonic over time, and the short and long-run price-elasticity of demand may have opposite sign....

Empirical evidence suggests that choices are affected by the amount of time available to the decision maker. Time pressure or a cooling-off period (mandatory delay of choice) changes how choices are determined. Yet, few models are able to account for the role of available time on decisions. This...

Although physicians are often expected to be gatekeepers to health insurance benefits such as paid sick leave, research indicates a substantial reluctance to reject patient requests for sickness certificates. We show that private information on the patient's part creates a conflict between the...

Economic policies rely on demographic projections. Yet in making these projections, researchers often ignore the aspect of household formation—despite sustained trends in many industrialized countries towards smaller household units with fewer members. Over the long term, this trend is likely...
