Abstract
Two models of technical inefficiency with a stochastic
production frontier are considered in this paper. In the frrst model, it
is assumed that the frontier itself does not vary with time, while in
the second, the frontier is allowed to move. These models are applied to
four years of panel data on wheat farmers in four districts of Pakistan:
Faisalabad and Attock in the Punjab, Badin in Sindh, and Dir in the
NWFP. Using essentially the same stochastic frontier production function
in each of the four districts involved, different stochastic
specifications for the inefficiency effects are obtained for the
different districts. Technical efficiencies of production of the
individual farmers are predicted in each year in which they are
observed. Varying patterns of technical inefficiency are observed. The
null hypothesis (of no technical inefficiency) cannot be rejected in
only one district. In the other districts, while inefficiencies appear
to be present in all of them, they are declining at a fairly rapid pace
in one. The results highlight the importance of analysis at a
disaggregated level because it is clear that both the rate of technical
change and relative efficiencies vary across regions and explicit
cognisance must be taken of this both in research and policy
formulation.
