Profit based efficiency measures, with an application to rice production in Southern India
Using non-parametric methods, we estimate the foregone rents due to credit, allocative, and technical inefficiencies of subsistence farmers in Southern India. The lost rents are estimated directly from the Nerlovian efficiency index, and the results suggest the largest foregone rents derive from allocative inefficiencies and then credit inefficienc...
Climate change and water supplies: options for sustaining tank irrigation potential in India
