COMPARISON OF DATA ENVELOPMENT ANALYSIS AND DETERMINISTIC PARAMETRIC FRONTIER APPROACHES: AN APPLICATION IN THE NORWEGIAN ROAD CONSTRUCTION SECTOR

摘要

This paper analyzes efficiency in the Norwegian road sector by using two competing methods. The first is Data Envelopment Analysis (DEA), while the second is Deterministic Frontier Analysis (DFA) with a Cobb-Douglas kernel specification. Both Approaches show similarities with respect to efficiency distribution.
