Taking a new look at empirical models of adoption: average treatment effect estimation of adoption rates and their determinants
This article shows that the "observed" sample adoption rate does not consistently estimate the population adoption rate even if the sample is random. It is proved that instead the sample adoption
Coexistence of genetically modified (GM) and non-GM crops in the European Union. A review
It is concluded that some of the currently proposed isolation distances are not in line with the coexistence principles laid down by the European Commission: they are excessive from a scientific point of view and difficult to implement in practice.
Reversing urban bias in African rice markets: A review of 19 National Rice Development Strategies
Abstract Economic development in poor countries is often hampered by urban bias. Partly as a result of historical urban bias, African countries have become heavily dependent on food imports with
Consumer valuation of improved rice parboiling technologies in Benin
Abstract In Benin, traditional parboiling is still widely practiced among rice processors, resulting in inferior grain quality. A new parboiler was introduced to improve the milling yield and
Regulating coexistence of GM and non-GM crops without jeopardizing economic incentives.
This paper argues for flexible coexistence regulations that explicitly take into account the economic incentives for coexistence, and provides a timely and important framework for EU policy-makers, who are currently struggling to implement coherent coexistence laws in all member states.
Boserup versus Malthus revisited: Evolution of farming systems in northern Côte d’Ivoire
Abstract In the literature on the evolution of farming systems in Sub-Saharan Africa, the theses of Malthus and Boserup seem to offer contrasting views on rural development. The purpose of the
Estimating Bird Damage to Rice in Africa: Evidence from the Senegal River Valley
Granivorous birds, mainly the Red-billed Quelea, have subsisted on cereal crops in Africa for centuries and have caused substantial damage. There is, however, limited recent evidence on their impact.
Parasitic weed incidence and related economic losses in rice in Africa
Parasitic weeds pose increasing threats to rain-fed rice production in Africa. Most important species are Striga asiatica, S. aspera and S. hermonthica in rain-fed uplands, and Rhamphicarpa fistulosa
Experimental auctions, collective induction and choice shift: willingness-to-pay for rice quality in Senegal
We propose a collective induction treatment as an aggregator of information and preferences, which enables testing whether consumer preferences for food quality elicited through experimental auctions
First impact of biotechnology in the EU: Bt maize adoption in Spain
A bio-economic model is built to estimate the impact of a biotechnology innovation in EU agriculture and finds that Transgenic Bt maize offers the potential to efficiently control corn borers, that cause economically important losses in maize growing in Spain.
