Nonparametric methods have been widely used for assessing the performance of organizations in the private and public sector. The most popular ones are based on envelopment estimators, like the FDH or DEA estimators, that estimate the attainable sets and its efficient boundary by enveloping the...

A feature of the recent global slowdown in productivity growth is that progress at the technological frontier has remained strong, while the gap between firms at the global frontier and other 'laggards' within an industry has grown. This growing gap reflects the fact that laggard firms now seem...

When there are efficiency spillovers, we can use a spatial autoregressive stochastic frontier model to estimate total (spillover-corrected) efficiencies. Glass et al. (2016) ( Journal of Econometrics ) provide a formula for total efficiency in this context, which is an approximation. We provide...

It is well known that when the empirical skewness of the OLS residuals display the opposite sign of what is expected from the stochastic frontier model, maximum likelihood estimation will be equivalent to OLS and no inefficiency will be recovered. A variety of approaches to operate in this...

Supply chain management (SCM) and total quality management (TQM) represent two parallel approaches to improving organizational performance. Previous studies have analyzed the SCM features impacting organizational performance independently of the design of TQM practices. Similarly, the recent...
