摘要：Using plot level production data from a nation-wide survey in India, we study the impact of irrigation on crop productivity, land prices and cropping intensities. Our main identification strategy is based on a sufficient number of households cultivating multiple plots of different irrigation status. After household fixed effects and plot characteristics are controlled for, our estimations show that irrigation has a strong and significant impact on all these outcomes with the dominant effects on cropping intensities. We find quality of irrigation also matters. Our results provide support for continuing investments to improve access and quality of irrigation in India.
