Previous studies have found that self-employed workers with long business tenure earn less than other workers with similar characteristics. This difference in earnings can be explained by the compensating wage differential theory when self-employed jobs have attractive non-earnings aspects....

The measure proposed in this paper is a new nonparametric data envelopment analysis (DEA) scheme, the hybrid measure, for determining efficiency in the presence of radial and nonradial inputs or outputs. Further extension of the scheme occurred to address nonseparable desirable and undesirable...

This paper presents a model to assess technical efficiency that incorporates value-added measures in schools as an output of the educational system. By using value-added measures, estimated from multilevel models, accurate, reliable and objective indices of the students' progress over time can...

This Chapter presents an application of quantile regression analysis in estimating the cost efficiency of 1,520 commercial banks operating in 73 countries during 2000-2006. This approach allows us to estimate banks' cost function for various quantiles of the conditional distribution and to...
