In this paper, using the Data Envelopment Analysis (DEA), we have measured the technical efficiency of cricket teams in the Indian Premier League. Taking the data for the 2009 season, the input used by the teams is approached by the total expenses which include players’ wage bill and wage of the support staff and other miscellaneous expenses. Output is measured by the points awarded, net run ra...

background: oral lesions are among the earliest clinical manifestations of human immunodeficiency (hiv) infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (aids). the purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in hiv/aids patients attending an hiv cente...

The National Health Service (NHS) is currently facing a financial crisis with a projected deficit of £2billion by the end of financial year 2015/16. As operating rooms (OR) are one of the costliest components in secondary care, improving theatre efficiency should be at the forefront of efforts to improve health service efficiency. The objectives of this study were to characterize the causes of ...

This paper estimates a translog stochastic frontier production function in the analysis of all 48 contiguous U.S. states in the period 1970-1983, to attempt to measure and explain changes in technical efficiency. The model allows technical inefficiency to vary over time, and inefficiency effects to be a function of a set of explanatory variables in which the level and composition of public capi...

In this paper, we consider economies with (possibly endogenous)solvency constraints under uncertainty. Long-run inefficiency corresponds toa feasible redistribution yielding a welfare improvement beginning from everycontingency reached by the economy. A sort of Cass Criterion (Cass [11]) com-pletely characterizes long-run inefficiency. This criterion involves only observ-abl...
