The default assumption of standard economics is to treat preferences as exogenously 'given', consistent with one another, 'revealed' by past choices, and context independent. There has been increased interest recently (within behavioural economics) in the impact of inconsistent or irrational...

In a model inspired by neuroscience, we show that constrained optimal perception encodes lottery rewards using an S-shaped encoding function and over-samples low-probability events. The implications of this perception strategy for behavior depend on the decision-maker's understanding of the...

Elisabeth Grewenig prepared this study while she was working at the Center for Economics of Education at the ifo Institute. The study was completed in March 2021 and accepted as doctoral thesis by the Department of Economics at the LMU Munich. It consists of five distinct empirical essays that...

This paper examines the reflexive interplay between individual decisions and social forces to analyze the evolution of cooperation in the presence of "multi-directedness," whereby people's preferences depend on their psychological motives. People have access to multiple, discrete motives....

What determines trade patterns? Habit persistence in consumer tastes and learning-by-doing in production imply that history and culture matter. Deriving a dynamic gravity equation from a simple model, it is shown that cultural similarity is a product of history, so that trade patterns are a...

People’s fairness preferences are an important constraint for what constitutes an acceptable economic transaction, yet little is known about how these preferences are formed. In this paper, we provide clean evidence that contrast effects arising from previous transactions play an important...

Can a major shock in childhood permanently shape trust? We consider a hunger episode in Germany after WWII and construct a measure of hunger exposure from official data on caloric rations set monthly by the occupying forces providing regional and temporal variation. We correlate hunger exposure...

We study risk preferences and their determinants for commercial cattle farmers in Namibia who are subject to high and heterogeneous precipitation risk, using data from questionnaire and field experiments, simulated data for on-farm precipitation risk and data on famers' previous place of...

We test the assumption that preferences are unchanged throughout a strategic game in the absence of feedback. To do so, we study the relationship between the strategic nature of a game and players' identification in social groups. We present evidence that the strategic nature of the game affects...

Economists have traditionally treated preferences as exogenously given. Preferences are assumed to be influenced by neither beliefs nor the constraints people face. As a consequence, changes in behaviour are explained exclusively in terms of changes in the set of feasible alternatives. Here we...
