讲座摘要：

This presents a four-component stochastic frontier model in which the frontier function is represented by an unknown smooth input distance function, and inefficiency is decomposed into persistent and transient inefficiencies. Furthermore, the pre-truncation mean and variance of the transient inefficiency are functions of the environmental variables. By differentiating the four-component input distance frontier with respect to the time trend, TFP growth is estimated under the semiparametric smooth coefficient framework, and is decomposed into six components, i.e., technical change, scale component, allocative component, external component, efficiency change, and residual component. The empirical example focuses on multiple outputs.
