Optimal redistribution with labor supply dependent productivity
摘要
We study optimal nonlinear income taxation when productivity depends negatively on labor supply (labor-supply-dependent productivity, LSDP). Relative to a benchmark model with fixed productivities, we find that LSDP leads to higher optimal marginal tax rates, especially for higher-income individuals, and greater redistribution. The key mechanism is that, under LSDP, marginal taxation becomes a more effective screening instrument.
