We develop a discrete-choice model of differentiated products for U.S. corn and soybean seed demand to study the welfare impact of genetically engineered (GE) crop varieties. Using a unique dataset spanning the period 1996-2011, we find that the welfare impact of the GE innovation is...

People often ignore or misunderstand information that would help them make better decisions. For products that differ by concentration level, a critical choice concerns the correct dosage rate. We study the effects of changing glyphosate product concentration levels on farmers' glyphosate usage...

Many decisions in agriculture are made over combinations of inputs and/or practices that may be complements. The presence of complementarity among producer decisions can have deep implications for market outcomes and for the effectiveness of policies intended to influence them. Identifying...

This study exploits a novel dataset containing more than 89,000 farm-level surveys over a 17-year period to investigate how neonicotinoid seed treatments in maize, now ubiquitous, have affected the use of other insecticides. Neonicotinoid insecticides are the most used class of insecticides in...

The extensive adoption of genetically engineered (GE) varieties in U.S. agriculture has dramatically changed the patterns of pesticide use. How this process ultimately affects environmental risk remains an open question. Previous studies have typically relied on aggregate trends to infer the...

La réduction des émissions liées à la déforestation et à la dégradation des forêts (REDD) dans les pays en développement est un nouveau mécanisme financier proposé pour le régime climatique post-2012 sous l'égide de la Convention-cadre des Nations Unies sur les changements...

This report examines how biodiversity co-benefits in REDD (Reducing Emissions from Deforestation and Forest Degradation) can be enhanced, both at the design and implementation level. It discusses potential biodiversity implications of different REDD design options that have been put forward in...

This report provides an overview of methodologies to evaluate the effectiveness of policy instruments for biodiversity, covering impact evaluation, cost-effectiveness analysis and other more commonly used approaches. It then provides an inventory of biodiversity-relevant impact evaluation...
