This article proposes a trade restrictiveness quantity index (TRQI) to measure the welfare impact of trade restrictions based on a distance functions approach. The TRQI embodies two Farrell measures of efficiency - respectively for producers and consumers - that can be computed using standard...

In this paper we take up the problem of positive, affine data translation within a Data Envelopment Analysis (DEA) framework.

In this note we derive alternative weighting schemes that complement those of Färe and Zelenyuk (2003) for consistent aggregation of Farrell efficiencies when the technology exhibits (global) constant returns to scale.
