The objective of this study is to investigate the relationship between the conceptions concerning development within the United Nations and Brazilian public policies. The starting hypothesis is: being a member of the UN, Brazil suffers influences from this organization in the conception, adoption and execution of its public policies, among which are those aimed at lower income families, such as the Bolsa Família. Therefore, an overview of conceptions of development present in the UN will be traced, beginning with classic liberalism and ending in the concept of human development, proposed by the economist Amartya Sen. There will be an attempt to identify the presence of these conceptions in the formulation and execution of the BolsaFamilia. The intention is not to state that there is a unilateral ideological imposition by the international organizations, but that UN constitutes itself in a plural space of permanent dispute between hegemonic and counter-hegemonic conceptions.
