Fronteira de produção e eficiência econômica da cafeicultura mineira

Abstract

This study has investigated the levels of economic efficiency of the productive resources of Minas Gerais coffee, identifying variations in the generation of obtained results through parametric and nonparametric methods. The data employed were the following: a) inventory of land, improvements, machinery, equipment, vehicles, implementation value of coffee plantations and further items of infrastructure of properties; b) technical indexes such as production and productivity; c) survey of components of fixed and variable costs: input and service costs. The data refer to agricultural years 2007/2008 and 2008/2009 which were adjusted for 2008/2009 season through agricultural price indicators and FGV IGP-DI. To analyze the management of productive resources, indicators of interest are technical allocative and economic efficiencies. As an analytical model we have used the Data Envelopment Analysis (DEA) - which is to find the best virtual company from a group of companies of a sample - and Stochastic Frontier - which is the assessment of mathematical functions according to reality series data, imposing a functional form to explain the levels of business efficiency. As a result it can be stated that DEA and stochastic frontier methodologies did not suggest different results to separate the coffee farmers for their economic efficiencies.
