Abstract
This paper uses both parametric and non-parametric approaches to estimate technical,
allocative, and economic efficiencies for the agriculture production in sixty provinces
of Vietnam in the period 1990-2005. Under different technology specifications, both
approaches show that the average technical, allocative, and economic efficiency estimates
were not high, and there would be a large room for the studied provinces to improve
their agricultural production efficiency. To examine consistency of the estimates
from two approaches under different specifications of returns to scale, we use Spearman
rank test, and the results indicate that parametric and non-parametric approaches
provide different estimates.
