Modeling dependence between error components of the stochastic frontier model using copula: Application to intercrop coffee production in Northern Thailand
© 2015 Elsevier Inc. In the standard stochastic frontier model, the two-sided error term V and the one-sided technical inefficiency error term W are assumed to be independent. In this paper, we relax this assumption by modeling the dependence between V and W using copulas. Nine copula families are c...
