This paper provides an empirical comparison of time-varying technical inefficiency measures obtained from the econometric estimation of different specifications of the stochastic production frontier model. Specifically, ten different frontier model specifications, which are most widely used in...

This paper derives sufficient conditions (in terms of supply and demand elasticities) for producers to gain under different supply shifts when supply and demand are specified to be linear functions and supply is inelastic. It is shown that regardless of the type of supply shift, producers lose...
