| 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. |

| This paper introduces a new market analysis methodology based on maximum likelihood estimation of a mixture distribution model incorporating price, transfer cost, and trade flow data. Not only does this method obviate statistical problems associated with conventional price analysis methods, it also permits differentiation between market integration and competitive market equilibrium. The model generates estimates of the frequency of alternative regimes, combinations of which provide useful, intuitive measures of intermarket tradability, competitive market equilibrium, perfect integration, segmented equilibrium, and segmented disequilibrium. An application to trade in soybean meal among Pacific Rim economies demonstrates the usefulness of the method. |

| Do rural households in developing countries make market participation and volume decisions simultaneously or sequentially? This article develops a two-stage econometric model that allows testing between these two competing hypotheses regarding household-level market behavior. The first stage models the household's choice of whether to be a net buyer, autarkic, or a net seller in the market. The second stage models the quantity bought (sold) for net buyers (sellers) based on observable household characteristics. Using household data from Kenya and Ethiopia on livestock markets, we find evidence in favor of sequential decision-making, the welfare implications of which we discuss. |

| This study uses a new market analysis methodology to examine price and trade relationships in eight Pacific Rim factor and product markets central to the Canadian and U.S. pork industries. The new method enables direct estimation of the frequencies with which a variety of market conditions occur, including competitive equilibrium, tradability, and segmented equilibrium. While extraordinary profit opportunities emerge episodically in a few niche markets, the vast majority of the markets studies are highly competitive- exhibiting zero estimated marginal profits to spatial arbitrage at monthly frequency- and internationally contestable. With a few notable exceptions due primarily to nontariff barriers, and despite significant remaining tariffs in some niches,... |

| The oft-observed inverse relationship between farm size and productivity is generally explained by labor market imperfections. Although other explanations exist (e.g., size-sensitive cropping patterns and variable soil quality), the literature ignores uncertainty as an explanation. Using a simple two-period model of an agricultural household that both produces and consumes under price uncertainty at the time labor allocation decisions are made, this paper demonstrates analytically that an inverse relationship may exist, even absent any of the more common explanations. A simple data exercise suggests the plausibility of temporal price risk as an explanation for this phenomenon. |

| Food-for-work (FFW) programs are commonly used both for short-term relief and long-term development purposes. In the latter capacity, they are increasingly used for natural resources management projects. Barrett, Holden and Clay (forthcoming) assess the suitability of FFW programs as insurance to cushion the poor against short-term, adverse shocks that could, in the absence of a safety net, have permanent repercussions. In this paper we explore the complementary question of FFW programs' potential to reduce poverty and promote sustainable land use in the longer run through induced changes in investment patterns. FFW programs commonly aim to produce or maintain potentially valuable public goods necessary to stimulate productivity and thus income growth.... |

| Perceptions of risk may vary within households as well as across households and communities. In this paper, we take advantage of panel survey data collected quarterly over a period of 2 ½ years to see how perceptions of risk vary across individuals over time. The surveyed households are in pastoralist communities in Northern Kenya and Southern Ethiopia and the survey period coincides with a severe drought in this region and the beginning of the recovery. We identify the structural heterogeneity of the perceptions of risk of these individuals. Because of the nature of panel data, we can also test how the perceptions of risk are affected by shocks in previous periods. In particular, we ask how an individual's risk perceptions change when shocks happen to... |

| 1. This paper was commissioned by the Trade and Markets Division of the Organisation for Economic Co-operation and Development (OECD) to address the relationship between food aid and commercial international food trade as background to an anticipated OECD study on the export competition aspects of food aid. The terms of reference for this study call for "a critical review of the existing literature on the potential use of food aid as an export support policy or, alternatively, the potential that food aid bears implications similar to those of export supporting policies." 2. This paper can be summarized as follows. Food aid has multiple objectives, modalities and effects and there has been significant movement over time in each of these areas.... |
