A Semiparametric Stochastic Frontier Model with Correlated Effects

Hajargasht, Gholamreza; Griffiths, William E. - In: Topics in identification, limited dependent variables, …, (pp. 1-28). 2019

We consider a semiparametric panel stochastic frontier model where one-sided firm effects representing inefficiencies are correlated with the regressors. A form of the Chamberlain-Mundlak device is used to relate the logarithm of the effects to the regressors resulting in a lognormal...
