in the presence of unknown serial correlation in the meta-frontier efficiency scores. The results from double bootstrap … efficiency can give significant contradictory results in efficiency scores. In the second stage, we use Simar and Wilson’s double … bootstrap regression to estimate the determinants of efficiency in Malaysian banks. This helps to achieve valid inference even …

We propose a computationally efficient approximation for the double bootstrap bias adjustment factor without using the … variance than those based on the double bootstrap and, lower adjusted mean-squared error than estimators based on the single …
