Sustainability matters

This document aims at bridging productivity measurement and weak sustainability in a specific data envelopment analysis framework that allows for negative output. In this framework countries use two inputs: capital and labour and seeks to maximize output and adjusted net saving. Adjustment net saving is seen as a sustainability indicator and then the productivity indicator computed can be understood as a sustainability productivity index. The higher the indicator is the higher productivity is and the probability of targeting sustainability. Copyright Springer Science+Business Media Dordrecht 2014
