In this chapter, we discuss the “lab-in-the-field” methodology, which combines elements of both lab and field experiments in using standardized, validated paradigms from the lab in targeting relevant populations in naturalistic settings. We begin by examining how the methodology has been...

Basic numeracy skills are obviously important for rational decisionmaking when agents are facing choices between risky prospects. Poor and vulnerable people with limited education and numeracy skills live in risky environments and have to make rational decisions in order to survive. How capable...

Advice is important for decision making, especially in the financial sector. We investigate how individuals assess risk preferences of others given sociodemographic information or pictures. Both non-professionals and fi nancial professionals participate in this artefactual field experiment....

Recent studies have found correlations between risk attitudes and several sociodemographic characteristics. In this paper, we deploy an artefactual fi eld experiment and study whether subjects - non-professionals and financial professionals - are aware of these correlations. This is largely...

We run a public good experiment in the field and in the lab with (partly) the same subjects. The field experiment is a true natural field experiment as subjects do not know that they are exposed to an experimental variation. We can show that subjects' behavior in the classic lab public good...

To investigate the external validity of laboratory results, we combine a public good experiment with three treatments in a field experiment. One treatment offers the opportunity to free-ride, the other two are placebo treatments. We compare results within subjects. In the free-riding treatment,...

Fungibility of money is a central assumption in the theory of consumer choice: any unit of money is substitutable for another. This implies that the composition of income or wealth is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many...

A key feature of markets for repugnant transactions is that certain transactions seem to raise moral concerns only when they involve high monetary incentives. Using a framed field experiment with a representative sample, I show that these preferences exist, and I investigate why people display...
