This paper presents a new dynamic ARCH-related conditionally heteroscedastic stochastic frontier model specification where firm and time-specific technical inefficiency is represented by an autoregressive stochastic process in the error components. Monte Carlo results reveal that a one-sided...

The purpose of this paper is to use the bootstrap resampling technique to calculate confidence intervals for efficiency measures and Malmquist productivity indices. The efficiency and productivity measures are obtained from non-parametric linear programming models using primal production data....

Recent availability of electronically accessible database of journal articles makes studies of the diffusion of papers through citations possible. Citation peaks have been found to be typically five to seven years, with a long tailing off. A seminal paper on theoretical and applied efficiency...

Cross country regressions on aid effectiveness have failed to provide substantial evidence on the effects of foreign aid. This study focuses on country performance in a production theory context. By means of the non-parametric DEA method, we study 60 individual low and middle income countries...

This thesis consists of five papers, four of them basically concerning environmental issues, while the fifth paper addresses the issue of measuring output from the educational sector. <p> The first paper starts from the fact that industrial activity causes environmental damage. Therefore, public...</p>

The purpose of this paper is to suggest a procedure to empirically test the Porter hypothesis. This hypothesis argues that environmental regulation not only increases environmental quality, but also brings the polluting producers information that makes them more resource efficient, as well as...

According to the economic literature, industrial clusters are groups of firms on the same <p> location composing a production system with spillovers that can be vertical and/or <p> horizontal. This paper focuses on horizontal clusters by exploring the spatial <p> distribution of industrial clusters in...</p></p></p>

This paper utilizes a unique county-level dataset to examine technical efficiency and technology gap in China’s agriculture. We classify the counties into four regions with distinctive levels of economic development, and hence production technologies. A meta-frontier analysis is applied to the...

Benchmarking by means of applying the DEA model is appearing as an interesting alternative for regulators under the new regimes for electricity distributors. A sample of large electricity distribution utilities from Denmark, Finland, Norway, Sweden and the Netherlands for the year 1997 is...
