|August 2018||The Impacts of Export Taxes on Agricultural Trade|
with Carmen Estrades, Manuel Flores, Angel Aguiar: w24894
Export taxes, despite being applied by several countries, have not received the same scrutiny in multilateral trade negotiations as other trade barriers. This work seeks to provide more detail into the linkages between export taxes, trade, food prices, and poverty in the agriculture sector. We first focus on how export taxes have impacted trade and international prices, applying a dynamic econometric-based gravity framework. Results show that export taxes do not have a widespread impact on international prices, but rather that the impact is concentrated in a few goods, mainly dairy products, live plants, vegetables, oilseeds and oils. We then use a computable general equilibrium model to examine the impacts to trade and poverty if export taxes were to be removed. These results indicate tha...

|February 2011||Commodity Price Volatility in the Biofuel Era: An Examination of the Linkage Between Energy and Agricultural Markets|
with Thomas W. Hertel: w16824
Agricultural and energy commodity prices have traditionally exhibited relatively low correlation. However, recent increases in biofuel production have altered the agriculture-energy relationship in a fundamental way. This increase has drawn on corn previously sold to other uses, as well as acreage devoted to other crops. The US RFS envisions a further boost of ethanol production to 15 billion gallons per year, which might be expected to further strengthen the linkages. We estimate that, in the presence of a binding RFS, the inherent volatility in the US coarse grains market will rise by about one-quarter. And the volatility of the US coarse grains price to supply side shocks in that market will rise by nearly one-half.
Under a high oil price scenario, rather than the RFS binding, the b...
