Unemployment in LDCs: Worker heterogeneity, screening, and quantity constraints (original) (raw)

Unemployment in many less developed countries is characterized by a significant urban-rural wage differential coexisting with high urban unemployment. This may be consistent with optimization when there is imperfect information about a worker's ability, and abilities are heterogeneous. Firms know only the average quality of workers in the labour pool. High urban wages induce inmigration of workers from rural areas, improving the average quality of the urban labour pool which has been depleted of high ability workers by previous screening. Hence, both sides of the market way find high non-market-clearing wages optimal. Quantity constraints from imperfect capital markets may strengthen this effect.
