This paper analyzes sin goods consumption when individuals exhibit present-focused preferences. It considers three types of present focus: present-bias with varying degrees of naiveté, Gul-Pesendorfer preferences, and a dual-self approach. We investigate the incentives to deviate from healthy...

The empirical effectiveness of economic policies that operate theoretically through similar channels differs substantially. We document this fact by comparing an easy-to-grasp expectations-based policy, unconventional fiscal policy, with a policy whose implications are harder to understand by...

In public good games, voluntary contributions tend to start off high and decline as the game is repeated. If high contributors are matched, however, contributions tend to stay high. We propose a formalization predicting that high contributors will self-select into groups committed to charitable...

This paper examines how households adjusted their consumption behavior in response to COVID-19 infection risk during the early phase of the pandemic. We use a monthly consumption survey specifically designed by the German Statistical Office covering the second wave of COVID-19 infections from...

We use an experiment to test whether consumers optimally acquire information on energy costs in appliance markets where, like many contexts, consumers are poorly informed and make mistakes despite freely available information. To test for optimal information acquisition we compare the average...

This paper investigates the direct and indirect effects of others’ beliefs on respondents’ own beliefs and consumer sentiment. Conducting consumer surveys with randomized control trials (RCTs) in Thailand and Vietnam during the COVID-19 pandemic, we implement two information treatments. Both...

Policy makers put great emphasis on the role of information about carbon emissions in achieving sustainable decisions by consumers. We conduct two studies to understand the optimal targeting of such information and its effects. First, we conduct an incentivized and representative survey among US...

Several empirical studies provide evidence that their actual health state affects people's attitudes towards health and medical care in hypothetical health states. In the tradition of behavioural economics this paper considers the actual health state as a point of reference and builds a model...

By means of a laboratory experiment, we show that, contrary to standard consumer theory, financially equivalent balance sheet profiles may be perceived as non fungible in a controlled frictionless environment with no probabilistic attributes. A large majority of subjects indeed have a bias in...

Non-pecuniary incentives motivated by insights from psychology (“nudges”) have been shown to be effective tools to change behavior in a variety of fields. An often unanswered question relevant for public policy is whether these promising interventions can be scaled up. In cooperation with a...
