In this paper, we test for productivity gains resulting from the introduction of a productivity-based incentive program in a large manufacturing plant of a Fortune 500 corporation. We develop a methodology based on a stochastic nonparametric frontier estimation technique to evaluate productivity in the postincentive plan period relative to the pre-incentive plan period. We also test for product...

Data envelopment analysis (DEA) is an axiomatic, mathematical programming approach to productive efficiency analysis and performance measurement. This paper shows that DEA can be interpreted as a nonparametric least squares regression subject to shape constraints on production frontier and sign constraints on residuals. Thus, DEA can be seen as a nonparametric counter-part of the corrected ordi...

In this paper we consider the specification and estimation of the Cobb-Douglas production function model. After reviewing the "traditional" specifying assumptions for the model which are based on deterministic profit maximization, we develop a model in which profits are stochastic and in which maximization of the mathematical expectation of profits is posited. "Sampling theory" and Bayesian est...

Consider a stochastic frontier model with one-sided inefficiency u, and suppose that the scale of u depends on some variables (firm characteristics) z. A “one-step” model specifies both the stochastic frontier and the way in which u depends on z, and can be estimated in a single step, for example by maximum likelihood. This is in contrast to a “two-step” procedure, where the first step is to es...

In the standard stochastic frontier model, the two-sided error term V and the one-sided technical inefficiency error term W are assumed to be independent. In this paper, we relax this assumption by modeling the dependence between V and W using copulas. Nine copula families are considered and their parameters are estimated using maximum simulated likelihood. The best model is then selected using...

The low production and productivity of sugarcane is a problem for the sugar industry in Indonesia, while demand increases yearly. One efforts to increase improving efficiency farming. Appropriate farming identification inefficient resources can productivity. PTPN X, as company engaged plantation industry, obtains most raw materials from partner farmers. This study aimed 1) determine technical, ...

This study analyzes the factors influencing gambier productivity, technical efficiency of farming, and affecting farming's efficiency. research was conducted in Lima Puluh Kota Regency, a production center West Sumatra. Data were analyzed using Cobb Douglas stochastic frontier function. The results showed that significantly influenced gambier's productivity labor, NPK fertilizer, plant age, num...
