The study examines how tax rates, corruption and various labour-market institutions affect the relative sizes of various segments of the labour market - the unemployed, the employed, the self-employed, and those working in the hidden economy - in the developed market economies. Regressive analyses of the OECD countries for 1995-2000 confirm that differences of tax rates and market institutions are joined by differences in the scale of corruption as important explanatory factors for relative size of the labour-market segments. With the hidden economy and self-employment, the coefficients of expressing the effect of tax rates themselves depend on the scale of corruption, as a manifestation of interaction between these.
