This paper investigates cost, technical and allocative efficiencies for Brazilian banks in the recent period (2000-2007). We use Data Envelopment Analysis (DEA) to compute efficiency scores. Brazilian banks were found to have low levels of economic (cost) efficiency compared to banks in Europe and in the US. For the period with high macroeconomic volatility (2000-2002) the economic inefficiency...

The study employs Battese-Coelli's time varying cost inefficiency model to examine Iran's banking efficiency. The data are collected from the financial state...
The shadow return on capital in 75 small municipal water systems is estimated using a gamma frontier variable cost function. The estimated Social Cost of capital exceeds the shadow return by an average ratio of 4.37:1, with a median capital stock inefficiency of $70, 500 per year per system owing to overinvestment in public water supply capital. In addition, actual production costs exceed minim...
