This study investigates risk and time preferences of small-holder cattle farmers in West Africa. We apply a discounted utility model and jointly estimate a prospect theory-based utility function and a quasi-hyperbolic discounting function using a maximum likelihood method. Results show that West...

We examine whether the experience of shocks influences individual risk attitude. We measure risk attitude via a simple survey item, compiled among more than 4,000 households in Thailand and Vietnam. The experience of adverse shocks, which is typical for poor and vulnerable households, is related...

The use of genetically engineered crop varieties has recently become one option to prevent pest damage in agriculture. The promoters of biotechnology stress the great potential for yield increase and pesticide reduction while the critics point out the potential risks for biodiversity and human...

Indigenous fruits contribute widely to rural incomes in Southern Africa but their availability is declining. A domestication program aims to increase farm-household income and conserve biodiversity through farmer-led tree planting. Planting domesticated indigenous fruit trees is an uncertain,...

Vulnerability to poverty is a major problem in the rural areas of Sub Saharan Africa. Rural Households are confronted with various covariate and idiosyncratic shocks and are often severely constrained in coping with such events. They frequently resort to food from natural resources such as...

Recent research on the Farmer Field School (FFS) approach in agriculture in developing countries has raised some doubts on the economic impacts of this concept and especially the knowledge diffusion effects from trained to non-trained farmers. Based on a study in Senegal this paper hypothesizes...

This study presents an economic valuation of health risks of pesticides among Nicaraguan vegetable farmers. A comprehensive valuation of market and non-market value components of human health is established through farmers? willingness to pay (WTP) for low toxicity pesticides. Results show, that...

Accurate poverty assessments in developing countries require efforts to collect detailed household level data. Especially in Africa, such procedures are time consuming, expensive and can be subject to numerous constraints. In this paper we discuss the procedure of the collection of data on...

Bt cotton has been cultivated in China for the past 10 years. Limitations of previous studies analyzing the impact of this technology are the short time period considered and lack of panel data. In this paper, we present findings from monitoring 150 Bt cotton farmers in 2002 and 2005....

This paper assesses the impact of risks and shocks on household welfare in the Hadejia-Nguru Wetlands in Nigeria. We use estimated income loss in consumption equations to assess the impact. Our findings identify death of an adult member, drought, and social conflict as important shocks in the...
