Estimating the Implicit Value of Crop Stubble as a Barrier to Technology Adoption in Morocco AgEcon
Magnan, Nicholas; Larson, Douglas M..
For mixed cereal-livestock farmers, cereal production provides a bundle of goods. Grain is consumed by the household or sold at market, and crop residues are used as livestock feed. The straw component of crop residue can be bought and sold at market and therefore has a well-established local market price. Crop stubble, the portion of the crop residue left on the ground, is generally not traded and therefore has no market price. Some agricultural technologies require farmers to forgo using crop stubble as feed, and cultivation of high value crops entails sacrificing residue production altogether. In this paper we apply a structural econometric model to household data from Morocco to estimate the implicit value of crop stubble. We use a sample splitting...

Implementing Rural-Urban Disaggregated Food Demand in a Partial Equilibrium Model AgEcon
Mason-D'Croz, Daniel; Magnan, Nicholas; Msangi, Siwa; Leroy, Laetitia.
Global general and partial equilibrium models focused on the agricultural sector can help policy makers do ex-ante analysis by providing a variety of macro-level outcomes, such as changes in flows of international trade, and changes in the supply, demand, and prices of globally traded commodities. IFPRI’s IMPACT model (International Model for Policy Analysis of Agricultural Commodities and Trade) model is one such model. Since its inception nearly 20 years ago the model has evolved to inform increasingly complex and nuanced policy issues, such as the explicit modeling of water use and the productive response of agriculture to climate change. However, on the demand side it has remained a fairly blunt instrument. One oft mentioned shortcoming of global...

POWDERY MILDEW RISK AND FORECASTING IN WINE GRAPES: DO GROWERS CHANGE RISK MANAGEMENT STRATEGIES IN RESPONSE TO DISEASE FORECASTS? AgEcon
Lybbert, Travis J.; Magnan, Nicholas; Gubler, W. Douglas.
How and how well growers manage the risks inherent in agriculture has direct welfare implications for producers and consumers at both local and societal levels. While better weather, pest and disease forecast information are rapidly disseminating among producers and are often touted as promising inputs to production and risk management, little is known about how this new information actually shapes producer behavior in practice. We argue that better forecast information can benefit growers and improve their capacity to manage disease and pests effectively, but that we must jointly consider the various margins of adjustment available to growers in order to properly understand their response to this improved information. Using the case of California wine...
