Waste management in the big cities of Indonesia is still become a complicated problem. This article aims to analyze the influence of socio-economic factors which consist of GRDP per capita, population density, gender ratio, the proportion of population productive age and education on the efficiency of waste management service (WMS) in provincial capitals in Indonesia. The method used was Stochastic Frontier Analysis (SFA). The resulted WMS efficiency from this study were 0.39. Based on that value, it means the efficiency of WMS are still low and the efficiency can be improved about 61%. It also can be concluded that all variables were significantly influenced the WMS efficiency, except gender ratio. Expected that the result of this study can be used by both central and local government to improve the WMS in Indonesia.

The construction and operation of air transport systems (ATS) needs huge investment, so its performance is of wide concern. The influences of social and economic factors in different regions must be considered when evaluating ATS performance. In this paper, a model combining data envelopment analysis, stochastic frontier analysis, and bootstrap technique is adopted to evaluate the ‘real’ performance of the air transport system in China. The evaluation results show the ATS performance in different regions. Social and economic factors are proved to pose influences on provincial ATS efficiency. Scale efficiency is the main factor that restricts the efficiency of China’s ATS. Technological change has determined the trend of ATS total factor productivity. The research results may implicate that improvements can be gained by modifying airspace limitations and regulatory conditions that impose significant constraints on ATS. The importance of ATS technological development strategy and the legitimacy of air transport modernization policy are also supported.

Avaliamos a eficiência técnica na provisão de serviços de saúde no Brasil, comparado com os países da América Latina, do Caribe e da OCDE. Estimamos um modelo econométrico em que outputs, entre os quais esperança de vida ao nascer; e índice de sobrevivência infantil, e uma variável de dispêndio, o gasto em saúde per capita, são utilizados para avaliar os serviços de saúde dos países. Foi utilizada a metodologia conhecida com Análise de Fronteiras Estocásticas (Stochastic Frontier Analysis - SFA). Nosso país apresenta indicadores de saúde desfavoráveis em relação aos países da amostra, e escores de eficiência muito baixos. Entretanto, em termos de posição no ranking de eficiência técnica relativa, o desempenho doBrasil é razoavelmente aceitável.
