This paper reviews the most recent empirical literature that assesses efficiency in higher education. We analyze 76 studies ranging from 1997 to 2018 and classify them according to the methodologies applied and to the definitions used to describe the outputs, inputs, quality and the context...

Purpose – The purpose of this paper is to assess and compare the forecast ability of existing credit risk models, answering three questions: Can these methods adequately predict default events? Are there dominant methods? Is it safer to rely on a mix of methodologies?...

The objective of this paper is to analyze the efficiency of the water sector in Latin American countries. We try to find factors affecting efficiency rather than identifying which country or individual provider is more or less efficient. We also consider which model would be more fitting for the...

The purpose of this paper is to assess comparative efficiency in water and sanitation sector in Brazil. We run a Sthocastic Frontier Analysis model for a panel of 127 providers, covering more than 70% of urban population of the country. We search and find an explanation for cost efficiency, and...
