Empirical Evidence on the New International Aid Architecture

We conduct an empirical study on how 22 donors allocate their bilateral aid among 147 recipient countries over the 1970-2004 period to investigate whether recent changes in the international aid architecture at the international and country levelhave led to changes in donor behavior. We find that after the fall of the Berlin Wall and especially in the late nineties, bilateral aid responds more to economic needs and the quality of a country’s policy and institutional environment and less to debt, size and colonial and political linkages. We also find more selectivity by donors when a country uses a PRSP and passes the HIPC decision point. Importantly, PRSPs and HIPCs reduce the perverse effects of large bilateral and multilateral debt shares on aid flows, suggesting less defensive lending. Overall, it appears certain international aid architecture changes have led to more selectivity in aid allocations. The specific factors causing these changes remain unclear, however. And since there remain (large) differences among donors in selectivity that appear to relate to donors’ own institutional environments, reforms will have to be multifaceted.

The Impact of Food Price Shocks in Uganda: First-Order Versus Long-Run Effects

We look at the immediate effects of these shocks faced by households in Uganda on their poverty and well-being. In addition, we look at the economywide impact in the long run when all markets have settled at a new equilibrium. We find that in the short run, poverty has increased substantially. However, in the longer run, we find welfare levels of rural farm households in particular to rise sharply, primarily as a result of increased returns to farm labor and agricultural land coupled with improved market prices for output sold.

Is there an App for that? The impact of community knowledge workers in Uganda

Rapidly increasing mobile phone coverage, cheaper technology, and an open platform that allows for the development of applications that extend the use of mobile devices provide new ways to reach farmers in isolated places. We investigate the impact of an intervention that uses information and communication technology devices to provide real-time agricultural information and extension services in Uganda. Using a difference-in-differences setup, we find that the introduction of this technology through a network of community knowledge workers induce farmers to adapt their crop portfolio, moving away from low-risk, low-value crops toward more commercially oriented commodities.

Nonlinear Dynamics of Livestock Assets: Evidence from Ethiopia

Recent research on the intertemporal dynamics of poverty using microeconomic data often hints at the existence of poverty traps, where some find themselves trapped at a low-level stable equilibrium while others enjoy a higher stable equilibrium. Without a sizable positive shock to well-being, those trapped at the low equilibrium will not automatically outgrow destitution, but merely fluctuate around that low-level equilibrium. Given the dramatic policy consequences implied by such a theory, knowledge about the location of the different equilibria would be extremely helpful. In this paper, we explore the possibilities of threshold-type models to identify those crucial parameters. We illustrate the method by searching for traps in the dynamics of livestock asset holdings in rural Ethiopia. We find evidence of distribution-dependent dynamics and multiple equilibria for tropical livestock units.

Who Engages in Water Scarcity Conflicts? A Field Experiment with Irrigators in Semi-Arid Africa

Does water scarcity induce conflict? And who would engage in a water scarcity conflict? In this paper we look for evidence of the relation between water scarcity and conflictive behavior. With a framed field experiment conducted with smallholder irrigators from semi-arid Tanzania that replicates appropriation from an occasionally scarce common water flow we assess what type of water users is more inclined to react in conflictive way to scarcity. On average, water scarcity induces selfish appropriation behavior in the experiment which is regarded conflictive in the Tanzanian irrigator communities where strong noncompetition norms regulate irrigation water distribution. But not all react to water scarcity in the same way. Poor, marginalized, dissocialized irrigators with low human capital and with higher stakes are most likely to react with conflictive appropriation behavior to water scarcity. Viewed a political ecology perspective we conclude that circumstances in Tanzania are conducive to resource scarcity conflicts. Water scarcity and water values are increasing. Water governance institutions entail exclusionary elements. Moreover, a higher likelihood to react in a conflictive way to water scarcity coincides with real economic and political inequalities which could form a basis for mobilization for more violent ways of competing for scarce resources.

Modernisation and Time Preferences in Tanzania: Evidence from a Large-Scale Elicitation Exercise

Abstract Assumptions about individual time preferences are important for explanations of poverty and development. Data from a large-scale elicitation exercise in Tanzania show significantly higher levels of impatience in urban areas than in rural areas. This result remains robust to adding controls for socio-economic differences between rural and urban areas, which possibly correlate with time preferences. We attribute this to differences in ‘modernisation’ between urban and rural areas, with modernisation leading to increased impatience. This is corroborated by the observed positive correlation between impatience and education; the latter being an important vehicle of modernisation for traditional societies in Tanzania.

Agricultural Extension Messages Using Video on Portable Devices: Increase Knowledge about Seed Selection and Seed Storage and Handling among Smallholder Potato Farmers in Southwestern Uganda

To feed a growing population, agricultural productivity needs to increase dramatically. Agricultural extension information, with its public, non-rival nature, is generally undersupplied, and public provision remains challenging. In this study, simple agricultural extension video messages, delivered through Android tablets, were tested in the field to determine if they increased farmers’ knowledge of recommended practices on (i) potato seed selection and (ii) seed storage and handling among a sample of potato farmers in southwestern Uganda. Using a field experiment with ex ante matching in a factorial design, it was established that showing agricultural extension videos significantly increased farmers’ knowledge. However, results suggested impact pathways that went beyond simply replicating what was shown in the video. Video messages may have triggered a process of abstraction, whereby farmers applied insights gained in one context to a different context.

Equity–Efficiency Optimizing Resource Allocation: The Role of Time Preferences in a Repeated Irrigation Game†

We study repeated water allocation decisions among small scale irrigation users in Tanzania. In a treatment replicating water scarcity conditions, convexities in production make that substantial efficiency gains can be obtained by deviating from equal sharing, leading to an equity–efficiency trade-off. In a repeated game setting, it becomes possible to reconcile efficiency with equity by rotating the person who receives the largest share, but such a strategy requires a longer run perspective. Correlating experimental data from an irrigation game with individual time preference data, we find that less patient irrigators are less likely to use a rotation strategy.

Sharing Common Resources in Patriarchal and Status Based Societies: Evidence from Tanzania

ABSTRACT In rural African societies, socioeconomic differentiation linked to gender and social status exerts an important influence on the distribution of common-pool resources. Through a behavioral experiment conducted in 2008 in rural Tanzania, this contribution examines the influence of gender and social status on distribution behavior of users of self-governed common watersheds. It finds that men and women with low social status distribute water equally when water is abundant but keep larger shares when water is scarce, although low-status women try to be as fair as possible at the expense of their returns from irrigated agriculture. Men of high social status keep more than half of the available water for themselves, both in abundance and scarcity, and deprive others from sizeable returns from irrigated agriculture. Women of high social status share altruistically when water is abundant and equally when water is scarce, giving up on returns from irrigated agriculture.

Fertility, Agricultural Labor Supply, and Production: Instrumental Variable Evidence from Uganda

Human fertility can affect agricultural production through its effect on supply of agricultural labor. Using the fact that in traditional, patriarchal societies, sons are generally preferred to daughters, we isolate exogenous variation in the number of children born to a mother and relate it to the agricultural labor supply and production in Uganda, which has a dominant agricultural sector and high fertility. We find that fertility has a sizable negative effect on household labor allocation to subsistence agriculture. Households with lower fertility devote significantly more time to land preparation and weeding; larger households grow less matooke and sweet potatoes. We find no significant effect on agricultural productivity in terms of yield per land area.
