Abstract
We conduct a pre-registered randomized controlled trial to test for income targeting in labor supply decisions among sellers of a Swedish street paper. Unlike most workers, these sellers choose their own hours and face severe liquidity constraints and volatile incomes. Treated individuals received a 25 percent bonus per copy sold for the duration of an issue, simulating an increase in earnings potential. Consistent with standard labor supply theory, they sold more papers and, by our measures, worked longer hours and took fewer days off. These findings contrast with studies on intertemporal labor supply that find small substitution effects.
