Comparison of the histories of three leading peasant organizations in the Pontal do Paranapanema region of Brazil-the Partido Comunista do Brasil (PCB) from 1945 to 1964, the Confederacao Nacional de Trabalhadores na Agricultura (CONTAG) from 1964 to 1984, and the Movimento dos Trabalhadores Rurais Sem-Terra (MST) from 1984 to 2004-suggests that continuity is as important as change in understanding Brazilian peasant movements. The MST has been considered a "new social movement" in that it has eschewed partisan politics, incorporated families as members rather than just male heads of household, had a national scope and a participatory decision-making structure, and been attuned to the international struggle over globalization. Placing it in historical perspective makes it clear, however, that this is not the first time that militants have organized around the concept of peasants as a political identity; that while the representation of peasants in the leadership of contemporary rural labor organizations may be greater than in the past, earlier peasant leaders also struggled on behalf of their class; that earlier peasant organizations had, if not a national presence, a substantial presence in the agricultural states of the time; and that attempts at international organization to unite peasant struggles around the globe are not entirely new. This is not to deny the innovative features of contemporary movements but to suggest that the investigation of past achievements will contribute to a fuller appreciation of these movements' conditions and prospects.

The Harris-Todaro model of the rural-urban migration process is revisited under an agent-based approach. The migration of the workers is interpreted as a process of social learning by imitation, formalized by a computational model. By simulating this model, we observe a transitional dynamics with continuous growth of the urban fraction of overall population toward an equilibrium. Such an equilibrium is characterized by stabilization of rural-urban expected wages differential (generalized Harris-Todaro equilibrium condition), urban concentration and urban unemployment. These classic results obtained originally by Harris and Todaro are emergent properties of our model.
