The recent crisis and turbulences have significantly changed the consumers’ behavior, especially through its access possibility and satisfaction, but also the new dynamic flexible adjustment of the supply of goods and services. The access possibility and consumer satisfaction should be...

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 order to address the impact of regulation on ethical concerns of consumers, we study the effect of a minimum wage. In our experimental market, consumers have monopsony power, firms engage in Bertrand competition, and workers are passive recipients of a wage payment. Two treatments are...

Laboratory experiments are an important methodology in economics, especially in the field of behavioral economics. However, it is still debated to what extent results from laboratory experiments can be applied to field settings. One highly important question with respect to the external validity...

This high-stakes experiment investigates the effect on buyers of mandatory disclosures concerning an insurance policy's value for money (the claims ratio) and the seller's commission. These information disclosures have virtually no effect despite most buyers claiming to value such information....

We examine experimentally the effect of complexity on individual decision making. We focus on credit choices, as they have been widely criticized for their complexity in recent years. In a first study, we find that complexity in benefits leads to random mistakes, while complexity in costs leads...
