How important is precautionary labor supply?
(2016) Schmitz, Sebastian; Rostam-Afschar, Davud; Jessen, Robin
We quantify the importance of precautionary labor supply using data from the German Socio-Economic Panel (SOEP) for 2001-2012. We estimate dynamic labor supply equations augmented with a measure of wage risk. Our results show that married men choose about 2.5% of their hours of work or one week per year on average to shield against unpredictable wage shocks. This implies that about 26% of precautionary savings are due to precautionary labor supply. If self-employed faced the same wage risk as the median civil servant, their hours of work would reduce by 4%.
Optimal taxation under different concepts of justness
(2017) Rostam-Afschar, Davud; Jessen, Robin; Metzing, Maria
A common assumption in the optimal taxation literature is that the social planner maximizes a welfarist social welfare function with weights decreasing with income. However, high transfer withdrawal rates in many countries imply very low weights for the working poor in practice. We reconcile this puzzle by generalizing the optimal taxation framework by Saez (2002) to allow for alternatives to welfarism. We calculate weights of a social planner’s function as implied by the German tax and transfer system based on the concepts of welfarism, minimum absolute and relative sacrifice, as well as subjective justness. For the latter we use a novel question from the German Socio-Economic Panel. We find that the minimum absolute sacrifice principle is in line with social weights that decline with net income. Absolute subjective justness is roughly in line with decreasing social weights, which is reflected by preferences of men, West Germans, and supporters of the grand coalition parties.
