Abstract
|
Before
This study will add to the body of research on incentive-induced behavior by quantifying the effect of various incentives on output. While a wide range of incentives have been shown to be effective (see Campbell, 2006), comparisons between different incentive types have been rare. This study hopes to quantify some of the difference between types of incentives, particularly in non-monetary forms (such as goal setting, comparison to others, etc.). The result of this study will form the basis for the elicitation of expert forecasts as registered in "Expert Forecasts of Amazon Turk Treatments".

Planned Number of Clusters
|
Before
The number of clusters is the same as the number of observations. 10,000 people is the ideal number of subjects planned for the study. The hope is to obtain at least 5500 subjects. The task will be kept open on Amazon Mechanical Turk until either (i) two weeks have passed or (ii) 10,000 subjects have completed the study, whichever comes first. If two weeks pass without 5500 subjects completing the task, then the task will be kept open (up to six weeks) until 5500 subjects are obtained.
