Widely accepted as a low-cost, fast-turnaround solution with acceptable validity, Amazon’s Mechanical Turk (MTurk) is increasingly being used to source participants for academic studies. Yet two commonly raised concerns remain: the presence of quasi-professional respondents, or...

The present article builds on a background paper that was commissioned for a “Witness Seminar” in 2010 that had a dozen prominent experimental economists -- witnesses, indeed -- discuss the origin and evolution of experimental economics. Rather than providing a history of the experimental...

Null Hypothesis Significance Testing has been widely used in the experimental economics literature. Typically, attention is restricted to type-I-errors. We demonstrate that not taking type-II errors into account is problematic. We also provide evidence, for one prominent area in experimental...

We study how donors decide which charity to give to. To this end, we construct a theoretical model that clarifies the conditions in which the stand-alone benefit from giving, price of giving, and cost of information acquisition inform giving decisions. The model shows that giving decisions are...

Self-regulatory organizations (SROs) can be found in education, healthcare, and other not-for-profit sectors as well as the accounting, financial, and legal professions. DeMarzo et al. (2005) show theoretically that SROs can create monopoly market power for their affiliated agents, but that...

The literature on dictator [D] and joy-of-destruction [JoD] games demonstrates that people can be nice and nasty. We study, by way of an experiment with between-subjects and within-subjects features, to what extent behaviors are context dependent and consistent. We find that, for one-shot D and...

In this paper, we reproduce Engel’s (2011) meta-study of dictator game experiments using his data, and then replicate it using our own data. We find that Engel’s (2011) meta-study of dictator game experiments is quite robust. We show that meta-analyses of dictator game experiments depend to...

I present a brief classroom demonstration illustrating Bertrand price undercutting. The classroom demonstration is appropriate for Micro Principles, and both intermediate and upper level undergraduate, as well as graduate classes in micro, Industrial Organization, and Game Theory

This chapter reports how stock portfolios that employed recognition heuristics fared relative to market indices, mutual funds, chance or dartboard portfolios, individual investment decisions, portfolios of unrecognized stocks and other benchmarks proposed by third parties.The surprising...

We explore experimentally a cognitive-effort channel through which defaults might influence behavior in an environment where the choice architect has misaligned incentives. Our experimental setting is an insurance market where the firm is better informed about the aggregate statistical risk...
