      abstract = {A stochastic frontier production function with  time-varying technical efficiencies is
estimated using  panel data from ICRISAT's Village Level Studies in three  Indian villages.
Given the specifications of a linearized  version of a Cobb-Douglas stochastic frontier
production  function with coefficients which are a linear function of  time, the hypothesis that
the traditional response function  is an adequate representation of the data is accepted  for
only one of the three villages. The hypothesis of  time-invariant technical inefficiencies is not
rejected for  one of the two villages for which significant technical  inefficiencies exist. The
hypothesis of time-invariant  elasticities of the input variables is rejected for two of  the three
villages. Further, the hypothesis that hired and  family labour are equally productive is
accepted in only  one of the three villages.
The technical efficiencies of  individual farms exhibited considerable variation in the  two
villages with either time-invariant or time-varying  technical efficiencies.},
