| Ecotourism, bioprospecting and non-timber product marketing have been promoted recently as market-based instruments for environment protection, but without sound understanding of the resulting net conservation effects. We present evidence on the local conservation effects of recent argan oil commercialization in Morocco, which seems a promising case study in conservation through resource commercialization. Our empirical analysis shows, however, that resource commercialization is not creating strong net conservation incentives because assumptions implicit in the prevailing logic prove incorrect in this case. Generally, the experience of southwestern Morocco provides a cautionary tale about the assumed efficacy of conservation strategies founded on resource... |

| Temporal climate risk weighs heavily on many of the world's poor. Recent advances in model-based climate forecasting have expanded the range, timeliness and accuracy of forecasts available to decision-makers whose welfare depends on stochastic climate outcomes. There has consequently been considerable recent investment in improved climate forecasting for the developing world. Yet, in cultures that have long used indigenous climate forecasting methods, forecasts generated and disseminated by outsiders using unfamiliar methods may not readily gain the acceptance necessary to induce behavioral change. The value of model-based climate forecasts depends critically on the premise that forecast recipients actually use external forecast information to update... |

| 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... |

| The effective design and implementation of interventions that reduce vulnerability and poverty require a solid understanding of underlying poverty dynamics and associated behavioral responses. Stochastic and dynamic benefit streams can make it difficult for the poor to learn the value of such interventions to them. We explore how dynamic field experiments can help (i) intended beneficiaries to learn and understand these complicated benefit streams, and (ii) researchers to better understand how the poor respond to risk when faced with nonlinear welfare dynamics. We discuss and analyze dynamic risk valuation experiments in Morocco, Peru, and Kenya. |

| Potential poverty traps among the rural poor suggest a need to reduce poor farmers' vulnerability by stabilizing crop yields and limiting yield losses. Advances in agricultural biotechnology enable breeders to address this need more directly than ever before with crops that reduce production risk by tolerating climate fluctuation or resisting biotic stresses. Will poor farmers who could benefit most from less vulnerability choose to purchase such risk-reducing seeds? I use data from a household survey and experiment involving farmers in India to infer their valuation of changes in the mean, variance, and skewness of yield distributions. I conclude that these farmers value increases in expected yield in the yield distribution but seem indifferent about... |

| Economists attribute many common behaviors to risk aversion and frequently focus on how wealth moderates risk preferences. This paper highlights a problem associated with empirical tests of the relationship between wealth and risk aversion that can arise when the probabilities individuals face are unobservable to researchers. The common remedy for unobservable probabilities involves the estimation of probabilities in a profit or production that includes farmer, farm and agro-climatic variables. Unfortunately, these variables are often correlated with wealth such that estimated probabilities are likely to leave statistical fingerprints on subsequently-estimated risk aversion coefficients and may thereby introduce spurious correlations between wealth and... |
