Much empirical research has shown that individuals’ decisions to adopt a new technology are the result of learning–both through personal experimentation through observing the experimentation of others. Yet even casual observation would suggest significant heterogeneity of learning processes, manifesting itself in widely varying patterns of adoption over space and time. This paper explores this heterogeneity in the context of early adoption of hybrid rice in rural India. Using specially designed experiments conducted as part of a primary survey in the field, we identify which of four broad learning heuristics most accurately reflects individuals’ information processing strategies. Linking these learning heuristics with observed use of rice hybrids, we demonstrate that pure Bayesian learning is well suited for the tinkering and marginal adjustments that are required to learn about a technology like hybrid rice, but it is also more cognitively taxing than other learning styles requiring a longer memory and more complex updating processes. Consequently, only about 25 percent of the farmers in our sample can be characterized as pure Bayesian learners. Present-biased learning and relying on first impressions will likely hinder adoption of a technology like hybrid rice, even after controlling for access to credit and a rudimentary proxy for intelligence.

In the context of a growing population in an already densely populated area, agricultural yields will need to increase without putting additional stress on the environment. The adoption of modern inputs by smallholders is an important ingredient of agricultural transformation. In this study we explore plot-level, household-level, and institutional-level characteristics associated with agricultural technology adoption behavior among smallholder farmers. The aim is to uncover correlations that can guide the design of policies and incentives that are likely to increase adoption. We explicitly differentiate between fixed costs that are likely to affect the decision to use the technology and variable costs that are more relevant for the decision regarding use intensity. In addition, we examine how the importance of each of these characteristics differs with asset status. To do so, we use data from about 1,880 potato plots cultivated by 500 randomly selected potato growers in southwestern Uganda. We first categorize households into poorly endowed and well-endowed asset classes based on their access to productive assets. We then estimate double-hurdle models for take-up and use intensity of fertilizer for each group. The results show that the factors associated with the decision to use fertilizer are often different from those associated with the decision about how much fertilizer to use and that the characteristics correlated with fertilizer adoption differ between asset-poor and asset-rich farmers. For instance, asset-poor female-headed households are less likely to use fertilizer, but if they do, they use more of it than male-headed households. Our results also suggest fertilizer packaging and distribution are important factors in fertilizer adoption decisions due to their impact on costs related to both indivisibilities and uncertainty about the quality. We derive a range of policy recommendations.

This review evaluates the role of the state in development, offering a new framework for understanding what capabilities states need to overcome different types of market failures. This framework is employed to understand the successes and failures of state-led development in Malaysia. The review addresses three key questions. First, what do we know about developmental states and why they emerged? Second, what have developmental states achieved? In answering this question, I look not only at growth but also at structural transformation, economic “upgrading,” equity, and human capability enhancement. In contrast to the idea of a single “East Asian model” of development, I find five distinct development trajectories. Third, how did developmental states utilize state structures to pursue development? To answer this final question, I examine in depth the history of state-led development in Malaysia—including agricultural, industrial, and social policies. This case study sheds light on what specific institutional and political capacities helped Malaysia to improve productivity in agriculture, expand the manufacturing sector, and reduce inequality. It also explores why Malaysia has been less successful in developing linkages with the export-based manufacturing sector.

Ethiopia’s Productive Safety Net Programme (PSNP) is a large-scale social protection intervention aimed at improving food security and stabilizing asset levels. The PSNP contains a mix of public works employment and unconditional transfers. It is a well-targeted program; however, several years passed before payment levels reached the intended amounts. The PSNP has been successful in improving household food security. However, children’s nutritional status in the localities where the PSNP operates is poor, with 48 percent of children stunted in 2012. This leads to the question of whether the PSNP could improve child nutrition. In this paper, we examine the impact of the PSNP on children’s nutritional status over the period 2008–2012. Doing so requires paying particular attention to the targeting of the PSNP and how payment levels have evolved over time. Using inverse-probability-weighted regression-adjustment estimators, we find no evidence that the PSNP reduces either chronic undernutrition (height-for-age z-scores, stunting) or acute undernutrition (weight-for-height z-scores, wasting). While we cannot definitively identify the reason for this nonresult, we note that child diet quality is poor. We find no evidence that the PSNP improves child consumption of pulses, oils, fruits, vegetables, dairy products, or animal-source proteins. Most mothers have not had contact with health extension workers nor have they received information on good feeding practices. Water practices, as captured by the likelihood that mothers boil drinking water, are poor. These findings, along with work by other researchers, have informed revisions to the PSNP. Future research will assess whether these revisions have led to improvements in the diets and anthropometric status of preschool children in Ethiopia.

How does the amount of land youth expect to inherit affect their migration and employment decisions? This paper explores this question in the context of rural Ethiopia using panel data from 2010 and 2014. We estimate a household fixed-effects model and exploit exogenous variation in the timing of land redistributions to overcome endogenous household decisions about how much land to bequeath to descendants. We find that larger expected land inheritances significantly lower the likelihood of long-distance permanent migration and of permanent migration to urban areas during this time. Inheriting more land is also associated with a significantly higher likelihood of employment in agriculture and a lower likelihood of employment in the nonagricultural sector. Conversely, the decision to attend school is unaffected. These results appear to be most heavily driven by males and by the older half of our youth sample. We also find several mediating factors matter. Land inheritance plays a much more pronounced role in predicting rural-to-urban permanent migration and nonagricultural-sector employment in areas with less vibrant land markets and in relatively remote areas (those far from major urban centers). Overall, the results suggest that inheritance strongly influences the spatial location and strategic employment decisions of youth.

At roughly 4 percent per year, labor productivity in Tanzania has grown more rapidly over the past 14 years than at any other time in recent history. Employment growth has also been strong, keeping up with population growth at roughly 2.5 percent per year; the bulk of employment growth (90 percent) has been in the nonagricultural sector. However, the vast majority of this nonagricultural employment growth has occurred in informal sector. Using Tanzania’s first nationally representative survey of micro-, small-, and medium-sized enterprises, this paper shows that firms in the informal sector contributed roughly half a percentage point to economywide labor productivity growth in Tanzania between 2002 and 2012. However, virtually all of the labor productivity growth contributed by informal firms came from a small subset of firms called the “in-between firms.” This paper considers attributes of the in-between firms that could be used for targeting financial and business services to firms with the potential to grow. This paper finds two salient characteristics of in-between firms that might lend themselves to targeting—their owners are more likely to keep written accounts and more likely to keep their savings in formal bank accounts.

Increasing numbers of development agencies and individual projects espouse objectives of women’s empowerment, yet there has been little systematic work on mechanisms by which interventions can enhance women’s empowerment. This gap exists because of the lack of consensus on indicators as well as the lack of attention paid to measuring the effects of different types of interventions on empowerment. This paper identifies the types of strategies employed by 13 agricultural development projects within the International Food Policy Research Institute’s Gender, Agriculture, and Assets Project Phase 2 (GAAP2) that have explicit objectives of empowering women. We distinguish between reach, benefit, and empowerment as objectives of agricultural development projects. Simply including women does not necessarily benefit them, and even activities that benefit do not necessarily empower. To identify strategies to empower women, we build on the domains included in the Women’s Empowerment in Agriculture Index (WEAI) and are working with the GAAP2 portfolio of projects to develop an empowerment metric that is applicable in the project setting (a project-level WEAI, or pro-WEAI). We have identified the following potential domains to be included in pro-WEAI: input into production decision making, control over resources, control over income, leadership, time, physical mobility, intrahousehold relationships, individual empowerment, reduction in gender-based violence, and decision making on nutrition. The GAAP2 projects address these domains through a wide variety of activities that can be grouped into four main types: (1) direct and indirect provision of goods and services; (2) forming or strengthening groups, organizations, or platforms and networks that involve women; (3) strengthening knowledge and capacity through agricultural extension, business and finance training, nutrition behavior change communication, and other training; and (4) changing gender norms through one-way awareness raising or two-way community conversations about gender issues and their implications. In general, projects with activities in more activity areas target more domains of empowerment, and most projects target a core set of six empowerment domains. With the exception of intrahousehold relationships, which is always targeted by activities designed to influence gender norms, projects target domains with different types of activities or combinations of activities. This setup suggests that there may be no one-to-one link between a specific activity and empowerment benefits, and that implementation modalities will determine whether and how an activity contributes to women’s empowerment. The effectiveness of these project strategies will be assessed using both quantitative and qualitative methods throughout the GAAP2 research project.

Despite improvements to the implementation regime of Ghana’s fertilizer subsidy program, this paper shows that considerable challenges remain in ensuring that the subsidy is targeted to farmers who need fertilizer the most. Currently, larger-scale and wealthier farmers are the main beneficiaries of subsidized fertilizer even though the stated goal is to target smallholder farmers with fertilizer subsidies. The experience of other African countries suggests that the effectiveness of fertilizer subsidies can improve with effective targeting of resource-poor smallholders. However, targeting smallholder farmers entails significant transaction costs and may even be infeasible in some cases. Faced with such challenges, Ghanaian policy makers must ponder the question of how to improve the targeting of input subsidy programs in the country. Further research is needed to identify more cost-effective approaches for achieving the goal of targeting.

This paper assesses the Subramanian and Deaton (S–D) approach for imputing the caloric intake of households from food prepared away from home (FAFH) and composite foods (CF) by juxtaposing it with the imputations of alternative approaches, and extends these approaches to four additional nutrients—vitamin A, iron, zinc, and calcium. The apparent relative nutritional insignificance of FAFH and CF in Bangladesh obfuscates our efforts to assess alternatives to the S–D approach to imputation, and we remain uncertain about the relative value of the alternative imputation approaches examined. FAFH and CF—although widely consumed in Bangladesh—constitute a relatively unimportant source of nutrients, regardless of how the nutrient content of FAFH and CF is imputed.

Industrial wages have increased significantly in China in recent years. At the same time, there have been widening gaps in wages across provinces. These trends are likely to prompt company headquarters to relocate. The relocation choices of headquarters are likely to change under different ownership, as a result of variations in their internal capabilities as well as the distinctive nature of their businesses. This paper is the first attempt to examine the effects of rising wages on headquarters’ relocation by ownership. Data were obtained from the China Statistical Yearbook and the Annual Survey of Industrial Enterprises for the period 1998 through 2008. These data allow for differentiation among companies with regard to five types of enterprises: foreign owned, Sino-foreign owned, state owned, domestically joint owned, and privately owned. We use a conditional logit model to identify factors to determine which province headquarters chose to relocate. In addition, we consider the impact of these choices on the “minimum wage standard” introduced in 2004. Results indicate that wages insignificantly affected the relocation choice of all types of headquarters before 2004. After 2004, on average, headquarters were more likely to relocate to low-wage provinces, as predicted by “overall cost leadership.” However, we also find that relocation choices are significantly affected by ownership type. While privately owned and state-owned enterprises are likely to relocate to areas with lower wages, foreign-owned headquarters tend to relocate to high-wage areas, as predicted by the “efficiency wage theory.” Wages did not affect the relocation choices of Sino-foreign-owned companies, but had a negative effect on those of domestically joint-owned headquarters.
