In this paper an attempt is made to explain the basic concept of efficiency, frontier production function, technical efficiency, deterministic frontier, and stochastic frontier. Efficiency of a firm/industry refers to its performance in the utilization of resources at its disposal and is a relative concept. Technical efficiency of a production function is defined as the maximum quantity of outp...

the problem of utilizing undesirable (bad) outputs in dea models often need replacing the assumption of free disposability of outputs by weak disposability of outputs. the kuosmanen technology is the only correct representation of the fully convex technology exhibiting weak disposability of bad and good outputs. also, there are some specific features of non-radial data envelopment analysis (dea...

Abstract The constant elasticity of substitution (CES for short) is a basic property widely used in some areas economics that involves system second-order nonlinear partial differential equations. One the most remarkable results mathematical states under homogeneity condition i.e. production function homogeneous certain degree, there are no other models with CES apart from famous Cobb–Douglas a...

This paper investigates the effect of ownership structure on the cost efficiency of Australian building societies using the stochastic econometric frontier approach. Contrary to the expense preference hypothesis, mutually-owned societies were found to be, on average, more cost efficient than those under stock ownership. Moreover, mutual and share-owned societies have significantly different cos...

This paper examines the efŽ ciency of electric power generation plants in the United States. A 1996 data set from the Utility Data Institute and county-level wage data from the Bureau of Labor statistics provide the information needed to construct measures of cost, output, and input prices for 78 steam plants using natural gas as the primary fuel. This paper uses a Bayesian stochastic frontier ...

Although FDI is widely believed to have a positive effect on economic growth, the exact mechanism of how FDI impacts upon the development process of the newly industrialising economies is far from being well understood. This paper presents and tests two propositions on the role of FDI in economic growth from a newly industrialising economy’s perspective. First, FDI is a mover of production effi...
