Resumo
This study aimed to analyze the technical efficiency of Emater municipal units in the State of
Goiás, Brazil. The methodological approach consists of a two-stage procedure. The first stage
consisted of a Data Envelopment Analysis (DEA). In the second stage, we used Tobit
regression and Stochastic Frontier Analysis (SFA) to evaluate the sources of efficiency. The
results of the first stage show that the units of Emater in Goiás presented efficiency
heterogeneity. We also found that average scale efficiency was 81.67%, which means that
issues related to scale reduce efficiency VRS about 18.33% in relation to CRS. From the
sample of 178 local units, only 15 units are efficient for the Variable Scale Return model. In
the second stage, variables such as distance from the capital (Goiânia), Municipal support,
Cattle herd, Proportion of employees with higher and technical level, among others, have
statistical significance to explain the efficiency of Emater's municipal units in Goiás. The
results can help to improve public policies, since it has been identified which municipal units
are inefficient and some sources of inefficiency.
