Viability of the Raw Cotton Production in Spain After the Decoupling of the Subsidies

Arriaza Balmón, Manuel; Gomez-Limon, Jose Antonio; … - International Association of Agricultural Economists - IAAE - 2006

Considering the latest reform of the EU's Cotton Regulation of 29th April 2004, which will come into force in the 2006/07 season, we analyse its impact on the cotton production sector of Andalusia. The decoupling of subsidies implies that producers will be entitled to 65 percent of the amount...

Evaluating the Potential of Whole-Farm Insurance Over Crop-Specific Insurance Policies

Bielza, Maria; Garrido, Alberto - International Association of Agricultural Economists - IAAE - 2006

Since 1996, different formats of whole-farm insurance (WFI) have been launched in North America and Spain. Their rationale is to pool all farm's insurable risks into a single policy that provides cheaper coverage against the farm's revenue losses. We evaluate the gains of moving from a situation...

Transaction Costs, Hold-Ups and Governance in Ethanol Supply Chains

Hobbs, Jill E.; Weseen, Simon; Kerr, William A. - International Association of Agricultural Economists - IAAE - 2012

The long-run commercial viability of ethanol production depends on the ability to access an inexpensive and reliable supply of inputs as well as finding stable markets for ethanol and its co-products. A unique feature of ethanol plants is their position at the intersection of multiple supply...
