Abstract This paper applies the meta-frontier Data Envelopment Analysis and main concepts of convergence from economic growth literature (?-convergence ?-convergence) to analyze integration both in efficiency technology gap European Union (EU) insurance markets. We evaluate 10 EU life markets over 17-year-period 1998–2014. Results show cost/revenue among major during sample period. These findin...

the non-differentiability and implicit definition of boundary of production possibility set (pps) in data envelopment analysis (dea) are two important difficulties for obtaining directional characteristics, including different elasticity measures and marginal rates of substitution. also, imposing weight restrictions in dea models have some shortcomings and misunderstandings. in this paper we ut...

(1) An acute phagedenic ulcer, circular in outline with sharp punched out edges usually commencing on the site of some trivial abrasion not necessarily of recent origin. The rapid increase in area and depth of the ulcer was appalling. Within 24 or 48 hours a trivial abrasion might become an ulcer as big as a rupee and with deep fascia exposed in its base.

In the use of peer group data to assess individual, typical or best practice performance, the effective detection of outliers is critical for achieving useful results, particularly for two-stage analyses. In the DEA-related literature, prior work on this issue has focused on the efficient frontier as a basis for detecting outliers. An iterative approach for dealing with the potential for one ou...

How to search the space of programs for a code that solves a given problem? Standard asymptotically optimal Universal Search orders programs by Levin complexity, implementing an exponential trade-off between program length and runtime. Depending on the problem, however, sometimes we may have a good reason to greatly favor short programs over fast ones, or vice versa. Frontier Search is a novel ...

Researchers of regional and international productivity comparisons are increasingly adopting various frontier approaches to examine convergence and the possible causes of productivity differences. We argue that economy-wide technology frontiers estimated with aggregate measures of output are downward biased. This bias extends not only to estimates of the technology frontier, but also produces i...
