Economia política da disputa por terras em Minas Gerais

O artigo estuda os determinantes da probabilidade de ocorrência de conflitos de terra, ocupações e assentamentos nos municípios mineiros. Os resultados apontam para a importância de fatores econômicos e políticos. Aparentemente, militantes pró-reforma agrária se adequam ao ciclo político, causando menos conflito em municípios governados por aliados.
