This paper uses a fully nonparametric approach to estimate efficiency measures for primary care units incorporating the effect of (exogenous) environmental factors. This methodology allows us to account for different types of variables (continuous and discrete) describing the main...

This paper by using Data Envelopment Analysis (DEA) and statistical inference evaluates the citation performance of 229 economic journals. The paper categorizes the journals into four main categories (A to D) based on their efficiency levels. The results are then compared to the 27 "core...

This study intends to understand how disaster is related to countries' production efficiency using a sample of 137 countries over 1980 - 2011. We analyze the effect of the number of man-made and natural disaster occurrences on countries' technological change (swift of the frontier) and...
