This research adopts the meta Dynamic Directional Distance Functions (DDF) model in order to calculate environmental efficiency and governance of China’s industrial sector from 2010 2017 overall, sub-regional, sub-provincial perspectives discusses technical gaps regional pollution control reasons for ineffective governance. The results show that overall level is relatively high over this time p...

This paper considers the measurement of firm’s specific (in)efficiency while allows for the possible heterogeneous technologies adopted by different firms. A flexible stochastic frontier model with random coefficients is proposed to distinguish technical inefficiency from technological differences across firms. Posterior inference of the model is made possible via the simulation-based approach,...

A stochastic frontier production function is defined for panel data on firms, in which the non-negative technical inetGciency effects are assumed to be a function of firm-specific variables and time. The inefficiency effects are assumed to be independently distributed as truncations of normal distributions with constant variance, but with means which are a linear function of observable variable...

The paper considers the multivariate gamma distribution for which the method of moments has been considered as the only method of estimation due to the complexity of the likelihood function. With a non-conjugate prior, practical Bayesian analysis can be conducted using Gibbs sampling with data augmentation. The new methods are illustrated using artificial data for a trivariate gamma distributio...

abstract quantitative analysis of production through evaluating the level of factor usage is a major part in agricultural management, which aims at increasing production by optimum usage of resources. this study has estimated and analyzed stochastic frontier production function and calculated technical efficiency of semi-mechanized broiler farms located in gorgan district. the survey data were ...

Data envelopment analysis (DEA) is used to measure the technical and scale efficiency of the domestic waste management function in 103 New South Wales' local governments. After allowance is made for nondiscretionary environmental factors which may affect the provision of these local public services, such as congestion and the inability to operate machinery in densely-populated urban areas, comp...

Admittedly the most crucial and the most neglected aspect of the spatial regression analysis, spatial contiguity remains an ambiguous concept that is largely dependent on the type of spatial units used and the characteristics of each application. The application of regression analysis to spatial data raises computational as well as conceptual issues. Computational issues consist in statistical ...

We focus on determining the impacts of government programs on farms’ technical inefficiency levels. We use Kumbhakar’s (2002) stochastic frontier model that accounts for both production risks and risk preferences. Our theoretical framework shows that decoupled government transfers are likely to increase (decrease) DARA (IARA) farmers’ production inefficiencies if variable inputs are risk decrea...

In this paper, a stochastic frontier model accounting for spatial dependency is developed using generalized maximum entropy estimation. An application is made for measuring total factor productivity in European agriculture. The empirical results show that agricultural productivity growth in Europe is driven by upward movements of technology over time through technological developments. Results ...
