The Effect Of The U.S. Biofuels Mandate On Poverty In India, Ujjayant N. Chakravorty, Marie-Helene Hubert, Beyza Ural Marchand
The Effect Of The U.S. Biofuels Mandate On Poverty In India, Ujjayant N. Chakravorty, Marie-Helene Hubert, Beyza Ural Marchand

More than 40% of US grain is now used for energy and this share is expected to rise under the current Renewable Fuels Mandate (RFS). There are no studies of the global distributional consequences of this purely domestic policy. Using micro-level survey data, we trace the effect of the RFS on world food prices and their impact on household level consumption and wage impacts in India. We first develop a partial equilibrium model to estimate the effect of the RFS on the price of selected food commodities - rice, wheat, corn, sugar and meat and dairy, which together provide almost …
Roads And Resources: Groundwater Depletion In Lankao Country In The North China Plains, Ujjayant N. Chakravorty, Xiangzheng Deng, Yazhen Gong, Martino Pelli, Zhang Qian
Roads And Resources: Groundwater Depletion In Lankao Country In The North China Plains, Ujjayant N. Chakravorty, Xiangzheng Deng, Yazhen Gong, Martino Pelli, Zhang Qian

China produces most of its food grains in the North China Plains. However, there is evidence that groundwater aquifers in this region are being overexploited. We use a unique GIS-referenced dataset of the depth of the water table for all the 12,000 odd tube wells in Lankao county. We find that the construction of new highways has led to a depletion of the water table in wells close to the highways. This relationship is robust to a variety of controls, including distance to river and primary canals, village and township fixed effects, the date of drilling of the well and …
Drilling In The Drought: The Industrial Organization Of Groundwater, Ujjayant N. Chakravorty, E. Somanathan
Drilling In The Drought: The Industrial Organization Of Groundwater, Ujjayant N. Chakravorty, E. Somanathan
Ujjayant Chakravorty
China and India together produce about half the world's rice and a third of the world's wheat, but production in both countries is heavily dependent on depleting groundwater resources. A large proportion of farmers buy and sell groundwater - the trading facilitated by small farm sizes and fragments land holdings. The economics of groundwater, when farm sizes are small, is little understood. This paper develops a simple, spatial model of the industrial organization of groundwater markets appropriate for smallholder agriculture. We show that if water is abundant, then equilibrium with free entry results in Bertrand competition, with water sellers charging …
The Effect Of Stock And Flow Regulation On Pollution From A Nonrenewable Resource, Ujjayant N. Chakravorty
The Effect Of Stock And Flow Regulation On Pollution From A Nonrenewable Resource, Ujjayant N. Chakravorty
Ujjayant Chakravorty
Many nonrenewable resources produce multiple pollutants which create different types of damage. For example, refineries use crude oil and produce sulphur and carbon. Sulphur is a flow pollutant which is mostly controlled by regulating emissions. However, carbon is a stock pollutant that builds in the atmosphere. The goal of the regulatory authority is to stabilize the stock of carbon at some pre-determined level. In this paper we examine the effect of flow and stock mandates on pollution from a non-renewable resource. We show that a stricter emissions mandate may lead to the stock mandate binding at an early date. On …
