Sophisticated and nai͏̈ve procrastination : an experimental study

The model of time-inconsistent procrastination by O'Donoughe and Rabin shows that individuals who are not aware of their present-bias (nai͏̈ve) procrastinate more than individuals who are aware of it (sophisticated) or are not present-biased (time-consistent). This paper tests this prediction. We classify participants into types using a novel measure, and require them to perform a real-effort task on one out of three dates. We find that sophisticated participants perform the task significantly later than nai͏̈ve participants. Our data suggest that this result may be explained by habit formation.
