Most hypotheses proposed to explain human food sharing address motives, yet most tests of these hypotheses have measured only the patterns of food transfer. To choose between these hypotheses we need to measure peopleç—´ propensity to share. To do that, I played two games (the Ultimatum and...

This study presents results from a pilot field experiment that tests predictions of competitive market theory. A major advantage of this particular field experimental design is that my laboratory is the marketplace: subjects are engaged in buying, selling, and trading activities whether I run an...

The role of anonymity in giving is examined in a field experiment performed in thirty Dutch churches. For a period of 29 weeks, the means by which offerings are gathered is determined by chance, prescribing for each offering the use of either 'closed' collection bags or open collection baskets....

There has been a dramatic increase in the use of experimental methods in the past two decades. An oft-cited reason for this rise in popularity is that experimental methods provide the necessary control to estimate treatment effects in isolation of other confounding factors. We question the...

The main purpose of this article is to advance a set of conditions which demand-revealing mechanisms must pass in order to be politically acceptable for real-world applications and - to begin with - for real-world experiments. Without such non-laboratory experiments, real progress seems unlikely...

Experienced construction industry executives suffer from a winner's curse in laboratory common- value auction markets. (Dyer et al. 1989). This paper identifies essential differences between field environments and the economic theory underlying the laboratory markets that account for the...

One conjecture in the theory of incentives is that incentives based on broader outcomes may be better at motivating agents than incentives based on narrow measures. A more nuanced statement of this conjecture is that incentives of different breadth are appropriate for different agents. We...

Several experimental studies have provided evidence that suggest indifference curves have a kink around the current endowment level. These results, which clearly contradict closely held economic doctrines, have led some influential commentators to call for an entirely new economic paradigm to...
