Summary Record of the Debate

Abstract

Professor Lindahl suggested that as an introduction to the problem of migration he might put Professor Thomas’s paper into perspective by outlining a scheme of types of migration. First, there was forced migration. For instance, one had the slave trade, and cases where, by government order, British convicts had been sent to Australia. Such questions had not been discussed in Professor Thomas’s paper. Second, there was free migration. Here, too, there were two possibilities; there were ‘push’ forces and there were ‘pull’ forces. Both the push and the pull forces might be either economic, for example abundant natural resources plus capital and technique, or political, like encouragements to emigration or restrictions on immigration.
