Risk, Self‐Employment and Differential Income Taxation

Abstract

Previous research has identified non-diversifiable risk and a preference for "being one's own boss" as key determinants of participation in self-employment. Using a simple model of occupational choice, I show how both factors can cause efficiency losses in a free market economy, and how linear differential occupational taxation can improve on the market outcome. A simulation exercise calibrated with UK data advocates a tax premium on employment incomes and a tax cut for the self-employed, in order to generate an efficiency gain of around a third of one per cent of GDP.
