This paper proposes a panel data based stochastic frontier model which accommodates time-invariant unobserved
heterogeneity along with efficiency effects. The efficiency effects are specified by a standard normal cumulative distribution
function of exogenous variables which ensures the efficiency scores to lie in a unit interval. The model is within-transformed
and then estimated with non-linear least squares. The finite sample properties of the proposed estimator are investigated
through a...[Show more]
