Data Set Description

The researchers develop an experiment to show that overprovision of costly effort is more likely to occur in work environments with working time autonomy in the absence of feedback. A key feature of the design is that it allows for a clean measurement of effort overprovision by keeping performance per unit of time fixed, which is achieved by calibrating subjects' productivity on a real effort task ex ante. This novel design can serve as a workhorse for various experiments as it allows for exogenous variation of perfor-mance certainty (i.e., by providing feedback), working time autonomy, productivity, effort costs, and the general incentive structure. The project finds that subjects provide significantly more costly effort beyond a level necessary to meet their performance targets in the presence of uncertainty, i.e., the absence of feedback, which suggests that feedback shields workers from overprovision of costly effort.
