  3. 3. Four Essays on the Measurement of Productive Efficiency

    University dissertation from Göteborg : Göteborg University

    Author : Dag Fjeld Edvardsen; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This collection of essays contains two kinds of contributions. All four essays include applications of the existing DEA (Data Envelopment Analysis) toolbox on real world datasets. But the main contribution is that they also offer new and useful tools for practitioners doing efficiency and productivity analysis. READ MORE
