Productivity and efficiency estimation: A semiparametric stochastic cost frontier approach

Sun, Kai; Kumbhakar, Subal C.; Tveterås, Ragnar - In: European Journal of Operational Research 245 (2015) 1, pp. 194-202

This paper proposes a flexible stochastic cost frontier panel data model where the technology parameters are unknown smooth functions of firm- and time-effects, which non-neutrally shift the cost frontier. The model decomposes inefficiency into firm and time-specific components and productivity...
