The present paper aims at evaluating the effect of regional policies in the agricultural field, with a specific focus on the Italian case. Provincial systems are evaluated through the Directional Output Distance Function (DODF) that is an extension of the Data Envelopment Analysis technique...

Apart from the well-known weaknesses of the standard Malmquist productivity index related to infeasibility and not accounting for slacks, already addressed in the literature, we identify a new and significant drawback of the Malmquist–Luenberger index decomposition that questions its validity...

This research analyses the environmental footprint of the airline industry in an attempt to highlight potential paths for improvement. We develop a directional economic-environmental distance function (DEED) which accounts for the production of both desirable and undesirable output and the...

This paper proposes the metafrontier non-radial Malmquist CO2 emission performance index (MNMCPI) for measuring dynamic changes in total-factor CO2 emission performance over time. The MNMCPI method allows for the incorporation of group heterogeneity and non-radial slack into the previously...

This paper constructs an innovative ratio of meta-technology cost (MTCR) by combining the meta-frontier framework and shadow price model. This ratio is not only an indicator to account for country-specific technology heterogeneity or technology heterogeneity across a group of countries to...
