The impact of weather shocks on crop yields: Evidence from India
Given that nearly half of the Indian labor force is employed in agriculture, extreme weather events may harm most of the country’s population. By exploiting annual variation within Indian districts, I test whether greater temperature fluctuations significantly decrease the output value of 13 major crops. I find that a 1°C deviation above the annual mean temperature leads to a 21.3 percentage point decline in output value for a given year, indicating substantial losses from large fluctuations in temperature. I also find evidence that proportion of crop area irrigated and fertilizer usage mitigates the negative impacts of temperature shocks.
期刊介绍:
The purpose of the Review is to foster and disseminate professional thought and literature relating to the economics of agriculture, natural resources, and community development. It is published twice a year in April and October. In addition to normal refereed articles, it also publishes invited papers presented at the annual meetings of the NAREA as well as abstracts of selected papers presented at those meetings. The Review was formerly known as the Northeastern Journal of Agricultural and Resource Economics
