While theoretically more efficient than starch-based ethanol production systems, conversion of lignocellulosic biomass … to ethanol is not without major challenges. A multi-region, multi-period, mixed integer mathematical programming model … encompassing alternative feedstocks, feedstock production, delivery, and processing is developed. The model is used to identify key …

Irrigation water demand is estimated using field-level panel data from Kansas over 16 years. The cost of pumping varies over time due to changes in energy prices and across space due to differences in the depth to water. Exploiting this variation allows us to estimate the demand elasticity while...

This paper examines impacts of an agricultural subsidy program on forest pressure in Malawi. Using household survey data, we measure the effect on forest product marketing and on forest clearing of Malawi's Starter Pack Scheme (SPS). Regression results show households receiving a free packet of...
