Does media exposure affect health behaviours? And how? We exploit the idiosyncratic switchover to digital television across Italian regions which exogenously increased the number of free view national channels and we link this to high-frequency data on the supply of food-related contents on the...

A nonparametric approach is presented to test whether decisions on a probability simplex could be induced by quasiconcave preferences. Necessary and sufficient conditions are presented. If the answer is affirmative, the methods developed here allow to reconstruct bounds on indifference curves....

This paper provides an efficient way to generate a set of random choices on a set of budgets which satisfy the Generalised Axiom of Revealed Preferences (GARP), that is, they are consistent with utility maximisation. The choices are drawn from an approximate uniform distribution on the...

It is shown how to test revealed preference data on choices under uncertainty for consistency with first and second order stochastic dominance (FSD or SSD). The axiom derived for SSD is a necessary and sufficient condition for risk aversion. If an investor is risk averse, stochastic dominance...

The positive correlation between hourly wages and height, which results in higher labor supply of tall individuals, is well-documented in the literature. Accepting the utilitarian perspective and assuming that height does not affect utility implies that linking income taxes to height is welfare...

According to the German SAVE survey, more than 40 percent of households regularly save fixed amounts rather than flexibly adjusting savings to income variations as assumed by the Permanent Income Hypothesis (PIH). Fixed amount saving behaviour could thus imply a challenge to PIH-based standard...

This article provides a robust non-parametric approach to demand analysis based on a concept called homothetic efficiency. Homotheticity is a useful restriction or assumption but data rarely satisfy testable conditions. To overcome this problem, this article provides a way to estimate homothetic...

We report the results of a combination of a dictator experiment with either a “social planner” or a “veil of ignorance” experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer...

We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. “Dictator games” with varying transfer rates used in Andreoni and...

We provide two methods to compute the largest subset of a set of observations that is consistent with the Generalised Axiom of Revealed Preference. The algorithm provided by Houtman and Maks (1985) is not comput ationally feasible for larger data sets, while our methods are not limited in that...
