This paper investigates how framing manipulations affect the quantity and quality of decisions. In a field experiment in elementary schools, 1.377 pupils are randomly assigned to one of three conditions in a multiple-choice test: (i) gain frame (Control), (ii) loss frame (Loss) and (iii) gain...

Fungibility of money is a central principle in economics. It implies that any unit of money is substitutable for another and that the composition of income is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many subjects do not treat money as...

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...

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...

Smartphone apps deliberately apply behavioral design, including algorithms sensing human behavior and personalized design elements affecting it. Untransparent behavioral design exploits an information asymmetry between app vendors and consumers and can lead to negative effects on consumers such...

Previous research shows that humans display complexity aversion. In this article, we test for the presence of complexity aversion and its determinants in the context of voluntary climate action, where individual choices interact with the complex regulatory framework of the EU Emission Trading...

We study the endowment effect and expectation-based reference points in the field leveraging the setup of the Socio-Economic Panel. Households receive a small item for taking part in the panel, and we randomly assign respondents either a towel or a notebook, which they can exchange at the end of...

In this paper we investigate behavioral constraints to savings among smallholder farmers in rural Ethiopia. Increasing savings by overcoming such behavioral constraints has been documented to have positive effects on various outcomes such as health, education, and agricultural investments. We...

A large fraction of households have very little savings buffer and are therefore vulnerable to financial shocks. We examine whether a social norm nudge can stimulate such households to save more by running a small-scale survey experiment and a large-scale field experiment at a retail bank in the...
