This article deals with estimating efficiency of world health systems using panel data on World Health Organization (WHO) member countries. The Stochastic Frontier (SF) approach is used for this purpose. We evaluate absolute efficiency as well as rankings and their sensitivity across alternative...

This paper deals with the estimation of efficiency in a panel data framework. A oneway error component model (ECM) is generalized to accommodate firm-specific variances for the inefficiency component. A multi-step procedure is developed to estimate the cost function and predict increase in cost...
