Abstract We propose a novel penalized splines method to estimate stochastic frontier model in which the is linear and inefficiency has single index structure with unknown link function index. The approach more flexible than traditional methodology requiring parametric and, at same time, it does not incur curse of dimensionality as fully non-parametric approach. procedure can be easily implement...

This paper adopts the stochastic frontier analysis (SFA) to model working capital efficiency (WCE) on a sample of 6170 European firms from 2009 2018. We find: (i) larger are more efficient with their management (WCM) than smaller firms, (ii) higher cash holding contributes WCE, (iii) high competition is less conducive WCE low competition, (iv) export and sales growth potential decrease (v) incr...

the technical, allocative and economic efficiency of wheat growers in baft, kerman province were studied to analyze the degree of farmers success in the optimun allocation of their resources and the possibilities of increasing the production based on the available resources and factors of production. sampling was based on random method, so 75 farmers were selected. the stochastic frontier produ...
