We propose a modification of kernel time series regression estimators that improves efficiency when the innovation process is autocorrelated. The procedure is based on a pre-whitening transformation of the dependent variable that has to be estimated from the data. We establish the asymptotic...

Data drain and data uncertainties for rival units affect the reliability and effectiveness of strategic plans for individual operational units. This study introduces a stochastic, multi-stage, optimization technique for short-term forecasting that intends to assist policy makers in developing...

Las aplicaciones empíricas basadas en los análisis de eficiencia resultan todavía muy escasas dentro del campo de las organizaciones culturales. En este trabajo se analiza la eficiencia mediante un modelo DEA output orientado no radial que se aplica a una muestra de 292 sociedades musicales...

This paper assesses the matching efficiency of the Portuguese public employment service, applying Data Envelopment Analysis combined with principal component analysis to Portuguese administrative data and comparing the situations in June 1998 and June 2001. We find evidence that the Portuguese...

The cost-effective public provision of high-quality goods and services is crucial for long-term growth. We study the determinants of public-sector efficiency (PSE) and in particular the role of citizens´ political values. Indeed, we argue that citizens´ willingness to monitor public affairs is...

This paper employs the data envelopment analysis (DEA) method to evaluate the performance of public spending and to show how productivity has changed over time for 18 selected OECD countries during 1995 to 2002. Our analysis shows that 14 countries exhibit variable returns to scale, meaning that...

This paper derives estimates of the efficiency of welfare spending in Slovenia and the other OECD countries from data envelopment analysis based on model specifications used in earlier OECD studies. Results suggest that Slovenia ranks about 25th among OECD countries for output efficiency: for a...

Results of data envelopment analysis sensitively respond to stochastic noise in the data. In this paper, by introduction of output augmentation and input reduction I extend additive models for stochastic data envelopment analysis (SDEA), which were developed by Li (1998) to handle the noise in...
