This paper argues that townward emigration, and its after-effects (remittances, return migration), in turn increases interpersonal and inter-household inequality within and between villages. As for rural labour productivity, the neoclassical expectation (that townward migration increases it) rests on special definitions and doubtful assumptions. Fortunately, in most of the poorer developing countries, rural-urban migration is much smaller, less permanent and more likely to set up countervailing economic-demographic pressures restoring the rural population share, than received opinion about ‘the urban crisis’ suggests. Migration does not equilibriate between urban and rural sectors, largely because of externalities and compositional factors; but it does smoothe itself, largely because individuals behave rationally and learn quickly. As so often, the lesson for development studies is not that ‘markets
