The Economic Effects of Pierce’s Disease in California: Preliminary Indications.
Karen M. Jetter and Joseph M. Morse, 2009 (pdf, 850 kb)
In 1989 a pest new to California, the glassy-winged sharpshooter, GWSS, was collected in Irvine, CA. By the mid 1990s it became apparent that the GWSS was a more deadly vector of the bacterium Xylella fastidiosa than were native sharpshooters. Xylella fastidiosa causes Pierce’s disease (PD) in grapes and has been endemic to California since the 19th century. However, because the GWSS is a more deadly vector of the bacterium, its establishment has led to an increase in both the severity and incidence of the disease in regions infested with GWSS.

Economics of the Mexican Ingreso Objetivo Program

Joseph V. Balagtas, and Daniel A. Sumner, 2008 (pdf, 154 kb)
The Ingreso Objetivo program in Mexico pays producers of program crops the difference between the government-set target price and a government forecasted market price established at planting time. The program benefi ts are available only to producers who sell eligible crops through registered handlers. The program was designed in part to compensate for losses of commercial growers associated with competition with imports and provides no benefits for subsistence growers and those who sell in casual
markets. This research, which was developed explicitly to assist the Mexican government in their review of agricultural policy, simulates the impacts of removing the policy on prices and quantities and welfare of producers, consumers and taxpayers. The simulations depend on assessments of market supply and demand parameters, but also on modeling
carefully some particular features of the multi-commodity program. We consider impacts under market conditions that prevailed in 2005. Clearly, if market prices continue as high as have occurred in 2008, the program has no market or welfare impacts.

Domestic Support Reform? A Closer Look at EU Policies Applied to Processing Tomatoes Between 1978 and 2008
Bradley J. Rickard and Daniel A. Sumner, 2008 (pdf, 620 kb)
Much research has been devoted to understanding the economic consequences of domestic support applied to agricultural markets, and the effects of altering domestic policy instruments. WTO trade negotiations have attempted to limit the type of domestic support used by members and the link between domestic support and traded quantities.
In 2003, the Common Agricultural Policy (CAP) in the European Union (EU) introduced the Single Farm Payment (SFP) for various animal products and fi eld crops. In 2006 the SFP was applied to cotton and olive oil, and in 2007 the EU decided to extend the SFP to various fruit and vegetable crops, including processing tomatoes. (In the United States, payments under the Agricultural Marketing Transition Act (AMTA) were introduced in the 1996 Farm Bill; renamed “direct” payments remained in the 2002 and 2008 Farm Bills. Our research explores the consequences of “reforms” of the EU processing tomato regime with the extension of the SFP.

Economic Effects of Climate Change on California Wine Industry - Research in Progress
Calanit Bar-Am and Daniel A. Sumner, 2008(pdf, 1000 kb)
• Climate and soil affect the yield and quality of grapes
• Temperatures above certain level may reduce the quality of some varieties and at some point may not be suitable for some wine regions
• Climate change may lead to the outbreak of existing diseases, such as Pierce Disease and Downy mildew, as well as new diseases
• The impact of climate change is not likely to be uniform across all varieties and regions
• Adaptation may moderate the climate change effects

Does 5 a day pay? The Benefits to Agriculture If Californians Ate the Recommended Amounts of Fruits and Vegetables in a Cancer Prevention Diet
Karen M. Jetter, James A. Chalfant and Daniel A. Sumner, (pdf, 2MB)
Fruit and vegetables industries stand to benefit significantly should Californians eat more fruit and vegetables. An increase in the demand for fruits and vegetables will cause prices to increase, leading to an increase in production and more product marketed within California. To capture these effects we developed a market model that links the agricultural industry to the retail market.

Biofuel Feedstock in a Diverse Agricultural Geography

Kurt Richter, Hyunok Lee, Daniel A. Sumner, 2008 (pdf, 6 MB)
Consider the likely availability of feedstock for a corn based ethanol plant in Northern California. We hypothesize a plant in Dixon, Solano County, CA drawing in feedstock from a 30 mile radius in Solano and Yolo Counties.
