Abstract: | Persistence of racial differentials in economic status may be to some extent due to the initially weak position of the disadvantaged groups which takes some time to disappear through the market process, but the equalizing process may be inhibited by private or collective discriminatory behaviour. Collective discrimination is sometimes effected by laws and regulations that constrain market prices. Two types of laws in particular will have discriminatory effetcs when viewed as a set of constraints on non-discriminatory behaviour. They occur when 1. the market behaviour of non-discriminators is constrained; e.g. laws and regulations proscribing the employment of members of certain groups in certain jobs or places, 2. the supply of non-discriminatory complementary factors of production is constrained by laws and regulations governing investment in human capital by certain racial groups, and by legislation relating to property and the requirements for residence. Confined to some aspects of 1., Black-White earnings differentials for 1951-1969 are analysed. Notes, appendix. |
