Explaining International Variations in Self-Employment: Evidence from a Panel of OECD Countries

Organisation for Economic Cooperation and Development (OECD) data from 1972 to 1996 reveals substantial differences in the levels and trends of self-employment rates across countries. This article uses recently developed panel integration and cointegration techniques to explore the determinants of aggregate self-employment rates. We find that within the panel, self-employment rates are positively and significantly related to personal income tax rates and negatively and significantly related to the unemployment benefit replacement rate. This accords a central role to government tax and transfer policies, in contrast to nonrobust influences from macroeconomic variables, which have been widely used in previous studies.
