TL;DR: The authors found that banks became more technically inefficient between 1984 and 1993, and that increasing inefficiency is reflective of an industry undergoing rapid technical change and adjustment of average firm size, but not necessarily a long-term decline.
Abstract: Numerous studies have found that US commercial banks are quite inefficient, and we find that, on average, banks became more technically inefficient between 1984 and 1993. Our analysis of productivity change, however, shows that technological improvements adopted by a few banks pushed out the efficient frontier, and that, on average, commercial banks experienced productivity gains. For banks with assets less than 0 million, however, technological improvement was insufficient to offset increased inefficiency, and thus productivity declined over the period. Our findings suggest that increasing inefficiency is reflective of an industry undergoing rapid technical change and adjustment of average firm size, but not necessarily a long-term decline.

TL;DR: In this article, the authors analyzed the four types of ownership structure in the US hospital industry-private nonprofit, private for-profit, federal, and state and local government, and used distance functions to measure technical efficiency of hospitals.
Abstract: The theoretical industrial organization literature cites varying factors which might influence the degree of technical efficiency achieved under different ownership structures in the US hospital industry. Unfortunately, this literature offers no consensus regarding the net direction and magnitude of these various effects. This study analyzes the four types of ownership structure in the US hospital industry-private nonprofit, private for-profit, federal, and state and local government. Distance functions are used to measure technical efficiency of hospitals producing multiple outputs relative to other hospitals in the sample, allowing comparisons among the different ownership types.

TL;DR: In this paper, a consistent bootstrap estimation procedure for obtaining confidence intervals for Malmquist indices of productivity and their decompositions is developed, which is an extension of earlier work described in Simar and Wilson (1996).
Abstract: This paper develops a consistent bootstrap estimation procedure for obtaining confidence intervals for Malmquist indices of productivity and their decompositions. Although the exposition is in terms of input-oriented indices, the techniques can he trivially extended to the output orientation. The bootstrap methodology is an extension of earlier work described in Simar and Wilson (1996). Some empirical examples are also given, using data on Swedish pharmacies.
