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...

In this paper, we compare experimentally measured individual risk attitudes and survey-based risk items for rural households in the province of Dak Lak in Southern Vietnam. In particular, we test whether the survey-based measure can be validated by a risk experiment among different ethnic...

Empirical studies advocating the temporal variability of risk attitudes suggest that adverse covariate shocks significantly alter risk attitudes over time, but there is no consensus on the direction. In this paper, we investigate whether risk aversion increases or decreases in response to...

In this paper we submit some thoughts on the possible implications of the COVID-19 pandemic for rural people in the countries of the Greater Mekong Subregion (GMS). We base our observations and conclusions on our long-term research experience in the region. The paper focuses on the economics of...

Climate risk is particularly burdensome to small-scale farmers in developing countries due to heavy dependence on natural resources, limited and erratic rainfall with high inter- and intra-annual variability, and other natural calamities. Numerous studies on climate change suggest that climate...

In this paper the class of Lower Partial Moments (LPMs) is used for measuring vulnerability as downside risk of household income in rural Cameroon. This class of established and coherent risk measures has been shown to meet a number of desirable properties. Among others, the LPMs fulfill the...

Several measures of vulnerability to poverty have been suggested in the literature. In practice, only little is known about the robustness of vulnerability comparisons based on these often quite specific measures. The theory of stochastic orders can be applied to shed some light on such issues....

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,...
