We analyse pricing, effort and tipping decisions in the online service Google Answers. While users set a price for the answer to their question ex ante, they can additionally give a tip to the researcher ex post. In line with the related experimental literature we find evidence that tipping is...

Many economic experiments are run in the laboratory with students as participants. In this paper we use a newspaper experiment to learn more about external validity of lab research. Our workhorse is the Yes-No game. Unlike in ultimatum games responders of the Yes-No games do not know the...

We conduct a natural field experiment on direct and indirect transfer mechanisms for small donations. Charitable contributions are significantly higher if made indirectly, i.e. if they are tied to the purchase of a good sold at a premium, than if they are made directly. Donations are...

This paper extends existing evidence on the interaction between financial incentives and cognitive capital. I focus on the impact of task-specific cognitive capital, the role of which is central to the capital-labor-production framework of Camerer and Hogarth (1999) and has long been studied in...

Gneezy, List and Wu [Q. J. Econ. 121 (2006) 1283-1309] document that lotteries are often valued less than the lotteries' worst outcomes. We show how to undo this result.

We replicate three pricing tasks of Gneezy, List and Wu (2006) for which they document the so called uncertainty effect, namely that people value a binary lottery over non-monetary outcomes less than other people value the lottery's worse outcome. Unlike the authors who implement a verbal...

We extend evidence on the interaction between financial incentives and cognitive abilities by focusing on the effect of task-specific abilities. In a memory-intensive task situated in an accounting context, the effect of accounting education on performance is stronger under financial incentives...

A long time ago most economists would have limited themselves to stating that agreements should be individually rational and efficient and that selecting a specific agreement from that set depends on bargaining and negotiation power whatever that may be. Nowadays hardly any economist will argue...
