A study into the impacts of reservations in public sector jobs on efficiency and productivity has revealed that there has been no reduction in productivity. On the contrary, productivity and efficiency have increased in some sectors. The report of the study, the first of its kind, by Ashwini Deshpande, Professor, Delhi School of Economics and  Thomas Weisskopf, Professor of Economics at the University of Michigan, was published in the World Development journal. The study was conducted on Group A and B level officers recruited from Scheduled Castes and Scheduled Tribes in the Indian Railways between 1980 and 2002.
