Abstract

We examine worker effort as a potential margin of adjustment to a minimum wage hike using unique data on piece rate workers who perform a homogenous task and whose individual output is rigorously recorded. By employing a difference-in-differences strategy that exploits the increase in Florida's minimum wage from $6.79 to $7.21 on January 1, 2009, and worker location on the pre-2009 productivity distribution, we provide evidence consistent with incumbent workers' positive effort responses.

Keywords: labor productivity, labor productivity, effort, effort, incentive, minimum wage
