Estimation of productivity in Korean electric power plants : a semiparametric smooth coefficient model

Heshmati, Almas; Kumbhakar, Subal; Sun, Kai - 2013

This paper analyzes the impact of load factor, facility and generator types on the productivity of Korean electric power plants. In order to capture important differences in the effect of load policy on power output, we use a semiparametric smooth coefficient (SPSC) model that allows us to model...
