This paper presents an efficiency analysis of Brazilian bulk terminals built upon the conjoint use of Data Envelopment Analysis and the bootstrapping technique. Confidence intervals and bias corrected central estimates were used as cornerstone tools, not only to test for significant differences...

This paper analyses the technical efficiency of Chinese fossil-fuel electricity generation companies from 1999 to 2011, using a Bayesian stochastic frontier model. The results reveal that efficiency varies among the fossil-fuel electricity generation companies that were analysed. We also focus...

In the housing market, new properties sometimes experience delays before they are sold. Such delays reflect the preferences of buyers in respect of the homes' characteristics. Therefore, it is important for managerial purposes to identify the causes of housing sales delays. After analysing the...

This study examines the time series behaviour of housing prices series for 69 cities in China. The general housing price index, the index of newly constructed buildings and the price index of second hand buildings from 2005:7 to 2010:12 are examined. The univariate fractionally integrated models...

This paper analyzes housing sales delay in Beijing, China. In the housing market, new properties sometimes experience delays before they are sold. Such delays reflect the preferences of buyers with regard to the characteristics of the housing. Therefore, it is important for managerial purposes...

This paper applies an innovative DEA (Data Envelopment Analysis) model, the Inverse -convex model, in order to investigate the technical efficiency of a representative sample of Chinese banks. The banks are ranked according to their efficiency over the period 1998-2008. The results paint a mixed...
