We design, field and exploit survey data from a representative sample of the French population to examine whether informative social interactions enter households'stockholding decisions. Re- spondents report perceptions about their circle of peers with whom they interact about financial matters,...

This paper studies whether pro-environmental consumption choices are consistent with utility maximization and what role the consumption behavior of reference persons and one's own past behavior play in this context. By combining data on individuals' pro-environmental consumption from a unique...

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...

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...

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...

In a simple conceptual framework, we organize a multitude of phenomena related to the (mis)prediction of utility. Consequences in terms of distorted choices and lower wellbeing emerge if people have to trade-off between alternatives that are characterized by attributes satisfying extrinsic...

Recent theoretical contributions have suggested consumption externalities, or peergroup effects, as a potential explanation for some of the puzzles in macroeconomics and finance. However, the empirical relevance of peer effects for intertemporal consumption choice is a completely open question....
