Are U.S. Corn And Soybeans Becoming More Drought Tolerant?, Tian Yu, Bruce A. Babcock Oct 2009

Are U.S. Corn And Soybeans Becoming More Drought Tolerant?, Tian Yu, Bruce A. Babcock

CARD Working Papers

An objective drought index that measures the dry and hot conditions adversely affecting crop yields is used in a regression analysis to test whether corn and soybeans have become more drought tolerant. Results indicate that corn yield losses from a drought of a given severity, whether measured in quantity terms or as a percentage of mean yield, have decreased over time. The null hypothesis that the absolute level of soybean yield losses due to drought has not changed cannot be rejected. But soybean yield losses in percentage terms have decreased over time. Because drought is the primary cause of yield ...


Indirect Land Use: The Folly Of Over-Indulgent Environmentalism?, Mark A. Edelman May 2009

Indirect Land Use: The Folly Of Over-Indulgent Environmentalism?, Mark A. Edelman

Economics Working Papers (2002–2016)

This working paper employs an alternatives and consequences approach to evaluate some of the potential consequences of using computer simulation models to estimate indirect land use for the purposes of regulating production of biofuels.


Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu Mar 2009

Land Allocation Effects Of The Global Ethanol Surge: Predictions From The International Fapri Model, Jacinto F. Fabiosa, John C. Beghin, Fengxia Dong, Amani E. Elobeid, Simla Tokgoz, Tun-Hsiang (Edward) Yu

CARD Working Papers

We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market, multi-commodity international FAPRI (Food and Agricultural Policy Research Institute) model. The model incorporates the trade-offs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with ...


Determinants Of World Demand For U.S. Corn Seeds: The Role Of Trade Costs, Sampath Jayasinghe, John C. Beghin, Giancarlo Moschini Jan 2009

Determinants Of World Demand For U.S. Corn Seeds: The Role Of Trade Costs, Sampath Jayasinghe, John C. Beghin, Giancarlo Moschini

CARD Working Papers

The United States is a large net exporter of corn seeds. Seed trade, including that of corn, has been expanding, but its determinants are not well understood. This paper econometrically investigates the determinants of world demand for U.S. corn seeds with a detailed analysis of trade costs impeding export flows to various markets, including costs associated with distance, tariffs, and sanitary and phytosanitary (SPS) regulations. The analysis relies on a gravity-like model based on an explicit specification of derived demand for seed by foreign corn producers, estimated based on data from 48 countries and for the years 1989 to ...
