This paper presents estimates of technical efficiency for Greek public hospitals using a non-neutral stochastic production frontier. In particular a translog production frontier is estimated for a panel data of 105 public hospitals over the period 1992-93. The estimated efficiency is found to be...

This paper characterizes the elasticity of factor substitution in one-sector convex growth models with a general production function. It shows that an elasticity of substitution that is asymptotically greater than one is a sufficient (but not a necessary) condition for the existence of a lower...
