This thesis consists of three articles which aimed the study of total factor productivity (TFP). The first one deals with the Latin American agricultural production, and analysis of the economic performance of countries, it is used the parametric approach of stochastic frontier production. It is observed that all country had positive TFP change in the period 1961-2010, which showed product growth as well as positive technical progress. The greatest TFP variation in Brazil is 55,73%, while the smallest change is in Trinidad and Tobago, 42.06%. However, the change in technical efficiency was decreased to nearly 50% of all countries. In the case of scale efficiency, only Argentina, Brazil and Uruguay had positive average for the period. Regarding the change in allocative efficiency, all countries were decreased. The second chapter studies the TFP and its decomposition in Brazilian agriculture from 1970 to 2006, using the Agricultural Census data and also by means of econometric model of stochastic frontier production to analyze the contribution of TFP agriculture. The estimated production boundaries were used to calculate the variation in total productivity Malmquist index, decomposed from varied levels of efficiency and technological change. The results showed a variation in positive Brazilian agriculture TFP, where Mato Grosso state expressed greater variation followed by Rio Grande do Norte, Amapá and Piauí. Important states for Brazilian agriculture as Bahia, Minas Gerais and São Paulo remained positive with the changes in TFP. Espírito Santo and Minas Gerais were the states that showed variation bigger than one in relation to technical efficiency, cathing-up effect. In the case of the regions, the Midwest showed greater gains in total factor productivity, followed by the Northeast and North. In the third chapter, the technical efficiency measures were studied the production of mangoes in Brazilian semi-arid region, in particular in Submédio São Francisco Valley. The study of the variables has also occurred by the estimation of the econometric model parametrics to chastic production function. It was concluded that only seven (7) producers from seventy-three (73) lots studied demonstrated technically efficient, bad statistic, since the in efficiency degree was over 90%.
