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...

This study investigates the long run relationship between government size and unemployment rate, the Abrams curve, using ten European countries over the period 1961-1999. To this end, panel cointegration analysis and estimation techniques appropriate for heterogeneous panels are made use of. The...

The paper examines the convergence properties of productivity in fifteen European countries over the period 1960-1997. European productivity is estimated using modified translog production systems with a completely general intertemporal structure. To capture the notion that trade may have an...
