  • Subsidies for Agricultural Technology Adoption: Evidence from a Randomized
           Experiment with Improved Grain Storage Bags in Uganda
    • Authors: Omotilewa O; Ricker-Gilbert J, Ainembabazi J.
      Pages: 753 - 772
      Abstract: This article addresses the question of whether subsidizing an entirely new agricultural technology for smallholder farmers can aid its adoption early in the diffusion process. Based on a theoretical framework for technology adoption under subjective uncertainty, we implemented a randomized field experiment among 1,200 smallholders in Uganda to estimate the extent to which subsidizing an improved grain storage bag crowds-out or crowds-in commercial buying of the technology. The empirical results show that on average, subsidized households are more likely to buy an additional bag at commercial prices relative to the households with no subsidy who are equally aware of the technology. This suggests that under certain circumstances, such as when there is uncertainty about the effectiveness of a new agricultural technology, and the private sector market for the technology is weak or nascent, a one-time use of subsidy to build awareness and reduce risk can help generate demand for the new technology and thus crowd-in commercial demand for it. In this context, a subsidy can allow farmers to experiment with the technology and learn from the experience before investing in it.

  • The Relationship between Farm Size and Productivity in Agriculture:
           Evidence from Maize Production in Northern China
    • Authors: Sheng Y; Ding J, Huang J.
      Pages: 790 - 806
      Abstract: The relationship between farm size and productivity has long been a topic of debate in development economics. Using farm-level panel data from 2003 to 2013, we investigate the relationship between maize yield and farm size in Northern China. After controlling for farm-specific characteristics, we restore a mild U-shaped relationship between maize yield and cropping area from the apparent inverse U-shaped curve. This suggests that an inverse farm size–productivity relationship persists for most small-sized farms. Further analyses demonstrate that farmer input choice between labor and capital is likely to smooth the non-linear farm size–productivity relationship, with capital use being more likely to affect the farm size–productivity relationship at a larger scale. The findings imply that subsidizing farmers to rent land without helping them become better-equipped could result in resource misallocation towards larger farms using less-efficient labor-intensive technologies.

  • Theoretical Production Restrictions and Agricultural Technology in the
           United States
    • Authors: Plastina A; Lence S.
      Pages: 849 - 869
      Abstract: Agricultural production studies are usually conducted using classical econometrics that make it difficult, if not impossible, to impose conditions derived from economic theory on flexible functional forms. Therefore, such conditions need not hold in estimation. We apply Bayesian econometrics to estimate a flexible production function using U.S. agricultural data under alternative restrictions dictated by theory, including a fully theoretically consistent model that satisfies all restrictions at each point of the data. The probability density functions of parameters, output elasticities, scale elasticity, and productivity gains vary substantially across models. Output elasticities from the fully theoretically consistent model suggest that agricultural production in the United States has typically been more responsive to land than to other factors of production. However, output became more responsive over time to changes in materials, and less responsive to changes in land and labor. By the early 2000s, the elasticity of output to materials was very similar to the elasticity of output to land. The elasticity of output to capital remained relatively stable over the entire sample. The estimates from the fully theoretically consistent model also show a slight increase in the average rate of productivity gains between the 1960s and the 1970s, a relative slowdown in the 1980s and 1990s, and a relative stabilization afterwards. All inputs are substitutes in production; all the elasticities of substitution have increased through the decades, though at different rates.

  • Technology Spillovers and Land Use Change: Empirical Evidence from Global
    • Authors: Villoria N.
      Pages: 870 - 893
      Abstract: We estimate the effects of agricultural technological progress on cropland expansion at various geographical resolutions, from the country level to the world as a whole, while formally accounting for the international interdependence of national supply responses. Evidence for these effects has thus far been scant, contributing to polarized perceptions about the potential for improving agricultural technologies as a means to slow down deforestation. We find that, in most countries of the world, growth in total factor productivity (TFP) is either uncorrelated or is positively associated with cropland expansion. Yet worldwide TFP growth have been an important source of global land savings. The divergence between the country-level and the global results is explained by the changes in production patterns as countries interact in international markets. Our preferred point estimate of the elasticity of global cropland to global TFP growth is -0.34. Moreover, we estimate that satisfying food demand from 1991 to 2010 without observed TFP growth would have necessitated an additional 173 million hectares, or close to 10% of the area covered by tropical rain forests.

      Pages: 894 - 918
      Abstract: Unconditional conservation payments are increasingly used by non-governmental conservation organizations to further their environmental objectives. One key objective in many conservation projects that use such unconditional payments schemes is the protection of tropical forest ecosystems in buffer zone areas around protected parks where the scope of instating mandatory restrictions is more limited. We use a randomized controlled trial to evaluate the impact of unconditional livelihood payments to local communities on land use outside a protected area—the Gola Rainforest National Park—which is a biodiversity hotspot on the border of Sierra Leone and Liberia. High resolution RapidEye satellite imagery from before and after the intervention was used to determine land use changes in treated and control villages. We find support for the hypothesis that unconditional payments, in this setting, increase land clearance in the short run. The study constitutes one of the first attempts to use evidence from a randomized control trial to evaluate the efficacy of conservation payments and provides insights for further research.

  • Agricultural Productivity and Forest Conservation: Evidence from the
           Brazilian Amazon
    • Authors: Koch N; zu Ermgassen E, Wehkamp J, et al.
      Pages: 919 - 940
      Abstract: A mix of public policy and market interventions in the mid-2000s led to historic reductions in deforestation in the Brazilian Amazon. The collateral impact of these forest conservation policies on agricultural production is still poorly understood, though evidence is sorely needed given the economic importance of agriculture in Brazil and many other forest-rich countries. We construct a ten-year panel dataset for agriculture and deforestation in the Brazilian Amazon (2004–2014), and use two complementary difference-in-difference strategies to estimate the causal effect of one of Brazil’s flagship anti-deforestation strategies, the Priority List (Municípios Prioritários), on agricultural production and productivity in three sectors: beef, dairy, and crop production. We find no evidence for trade-offs between agriculture and forest conservation. Rather, reductions in deforestation in priority municipalities were paired with increases in cattle production and productivity (cattle/hectare), consistent with a model where policy-induced decreases in the value of clearing new land cause credit-constrained farmers to shift investments from deforestation to capital investments in farming. The policy had no consistent effect on dairy or crop production. Our results suggest that in regions with large yield gaps and where technologies for increasing yields are readily available, efforts to constrain agricultural expansion through improved forest conservation policies may induce intensification.

  • Insuring Well-Being' Buyer’s Remorse and Peace of Mind Effects
           From Insurance
    • Authors: Tafere K; Barrett C, Lentz E.
      Pages: 627 - 650
      Abstract: We estimate the causal effects of index insurance coverage on subjective well-being among livestock herders in southern Ethiopia. By exploiting the randomized distribution of discount coupons and information treatments to instrument for the purchase of index-based livestock insurance, and three rounds of panel data, we separately identify ex ante welfare gains from insurance that reduces risk exposure and ex post buyer’s remorse effects that may arise after the resolution of uncertainty. We find that current insurance coverage generates subjective well-being gains that are significantly higher than the buyer’s remorse effect of an insurance policy that lapsed without paying out. Given the positive correlation in insurance purchase propensity over time, failure to control for potential buyer’s remorse effects can bias downward estimates of welfare gains from current insurance coverage.

  • After the Drought: The Impact of Microinsurance on Consumption Smoothing
           and Asset Protection
    • Authors: Janzen S; Carter M.
      Pages: 651 - 671
      Abstract: To cope with shocks, poor households with inadequate access to financial markets can sell assets to smooth consumption and, or reduce consumption to protect assets. Both coping strategies can be economically costly and contribute to the transmission of poverty, yet limited evidence exists regarding the effectiveness of insurance to mitigate these costs in risk-prone developing economies. Utilizing data from an RCT in rural Kenya, this paper estimates that on average an innovative microinsurance scheme reduces both forms of costly coping. Threshold econometrics grounded in theory reveal a more complex pattern: (i) wealthier households primarily cope by selling assets, and insurance makes them 96 percentage points less likely to sell assets following a shock; (ii) poorer households cope primarily by cutting food consumption, and insurance reduces by 49 percentage points their reliance on this strategy.

  • Does Index Insurance Crowd In or Crowd Out Informal Risk Sharing'
           Evidence from Rural Ethiopia
    • Authors: Takahashi K; Barrett C, Ikegami M.
      Pages: 672 - 691
      Abstract: We study how the introduction of a formal index insurance product affects informal risk-sharing among pastoralists in southern Ethiopia. Using detailed social networks data, randomized incentives to purchase the insurance product, and hypothetical informal transfer data that mirror the existing customary arrangements, we find respondents’ own formal insurance uptake has no significant effect on their willingness to share risk through customary institutions. We also find weak evidence that a randomly matched peer’s insurance uptake positively influences respondents’ willingness to make informal transfers to that match. Overall, our results imply that in this context index insurance does not crowd out informal risk-sharing mediated by social networks.

  • Agricultural Microcredit for Tenant Farmers: Evidence from a Field
           Experiment in Bangladesh
    • Authors: Hossain M; Malek M, Hossain M, et al.
      Pages: 692 - 709
      Abstract: We study the impact of an agricultural microcredit program on the livelihoods of small, marginal, and landless tenant farmers in Bangladesh based on a Randomized Control Trial (RCT). Twenty percent of eligible households acquire at least one loan from the program within two years of the start of the intervention. Results show that access to credit has positive but imprecisely estimated effects on adoption of modern varieties (MV) of rice as well as rice yield. The microcredit program increases crop farm income but has no significant effect on total income or expenditure. Although the program does not have a significant effect on most economic outcomes, it demonstrates an increase in farm activities among the targeted farmers. Our study suggests that facilitating access to credit without addressing other constraints may not be enough to increase investment and profits of tenant farmers.

  • Money Matters: The Role of Yields and Profits in Agricultural Technology
    • Authors: Michler J; Tjernström E, Verkaart S, et al.
      Pages: 710 - 731
      Abstract: Despite the growing attention to technology adoption in the economics literature, knowledge gaps remain regarding why some valuable technologies are rapidly adopted, while others are not. This paper contributes to our understanding of agricultural technology adoption by showing that a focus on yield gains may, in some contexts, be misguided. We study a technology in Ethiopia that has no impact on yields, but that has nonetheless been widely adopted. Using three waves of panel data, we estimate a correlated random coefficient model and calculate the returns to improved chickpea in terms of yields, costs, and profits. We find that farmers’ comparative advantage does not play a significant role in their adoption decisions and hypothesize that this is due to the overall high economic returns to adoption, despite the limited yield impacts of the technology. Our results suggest economic measures of returns may be more relevant than increases in yields in explaining technology adoption decisions.

  • Nutrient Production and Micronutrient Gaps: Evidence from an
           Agriculture-Nutrition Randomized Control Trial
    • Authors: Dillon A; Arsenault J, Olney D.
      Pages: 732 - 752
      Abstract: Integrated agriculture nutrition programs can increase the quantity and quality of nutritious foods through multiple pathways. Increased household production increases the availability of own produced food for consumption, as well as income for food purchases. Increased knowledge of nutrition introduced through a behavior change communication strategy can change food preferences and shift purchasing decisions towards nutritious foods. In a randomized control trial, we demonstrate that an integrated agriculture-nutrition program in Burkina Faso improved the quality of diets by reducing household macro and micronutrient consumption gaps. We estimate production and consumption nutrient gaps for households in our sample by comparing reported consumption or production of nutrients relative to recommended daily allowances for households. Differences between actual nutrient consumption and production values and the recommended daily allowances provide an estimate of the nutrient gaps (surplus or deficit) within the household. We find that the integrated agriculture-nutrition program reduced consumption nutrient gaps in treatment households. We also investigate whether the production or nutrition knowledge pathways explain the consumption nutrient gap treatment effects. Though crop choice led to a diversified household production of nutritious foods in treatment villages on the extensive production margin, increased household production of nutrients does not explain the improvements in diet quality due to limited treatment effects for the estimated production nutrient gaps at the intensive production margin. Consumption expenditures in treatment villages did increase purchases of nutritious foods, suggesting that the behavior change communication strategy is effective at not only increasing nutrition knowledge, but also in affecting consumer preferences.

  • Does Trade Policy Impact Food and Agriculture Global Value Chain
           Participation of Sub-Saharan African Countries'
    • Authors: Balié J; Del Prete D, Magrini E, et al.
      Pages: 773 - 789
      Abstract: The emergence of food and agriculture global value chains (GVCs) is challenging the way scholars look at trade data, as well as how policy makers establish their trade policies. The common perception is that Sub-Saharan African (SSA) countries, unlike most Latin American and Asian countries, are not deeply integrated into global production networks. Consequently, it is believed that the border protection policies of the former may have a limited impact on GVC participation. This paper challenges this conventional knowledge in two ways. First, by decomposing bilateral gross export into its value added components, we show that the sectoral and bilateral SSA participation in GVC for food and agriculture is substantial. Second, we demonstrate that trade policies impact backward and forward value chain linkages. These results call for a refinement of trade policy priorities in SSA.

  • Estimating Ex Ante Cost Functions for Stochastic Technologies
    • Authors: Chambers R; Serra T.
      Pages: 807 - 824
      Abstract: This paper revisits the problem of estimating ex ante cost functions previously studied by Pope and Just in 1996, as well as Moschini in 2001. An ex ante cost function that generalizes their ex ante cost functions is introduced, and an econometric procedure for estimating a flexible approximation to it is developed. That generalized cost function is economically relevant not only for the Pope and Just 1996 choice setting, but for general producer risk preferences, general stochastic technologies, and general forms of price uncertainty. An econometric strategy for estimating the resulting cost structure that adapts Moschini’s 2001 “full-information” approach is developed, followed by an econometric application to U.S. agriculture.

  • How Reliable is Duality Theory in Empirical Work'
    • Authors: Rosas F; Lence S.
      Pages: 825 - 848
      Abstract: The Neoclassical theory of production establishes a dual relationship between the profit value function of a competitive firm and its underlying production technology. This relationship, commonly referred to as duality theory, has been widely used in empirical work to estimate production parameters such as elasticities and returns to scale. We generate a pseudo-dataset by Monte Carlo simulations, which, starting from known production parameters, yield a dataset with the main characteristics of U.S. agriculture in terms of unobserved firm heterogeneity, decisions under uncertainty, unexpected production and price shocks, endogenous prices, output and input aggregation, measurement error in variables, and omitted variables. Production parameters are not precisely recovered when performing econometric estimation based on the duality approach, and the elasticity estimates are inaccurate. Deviations of own- and cross-price elasticities from initial median values, given our parameter calibration, range between 6% and 690%, with an average of 90%. Also, own-price elasticities are as imprecisely recovered as cross-price elasticities. Sensitivity analysis shows that results still hold for different sources and levels of noise, and sample size used in estimation.

  • Optimal Tenurial Contracts Under Both Moral Hazard and Adverse Selection
    • Authors: At C; Thomas L.
      Pages: 941 - 959
      Abstract: This paper determines the optimal tenurial contract between a monopoly landlord and a tenant protected by limited liability under both adverse selection (based on the tenant’s ability) and moral hazard (based on the tenant’s choice of effort). We identify different optimal contracts depending on the tenant’s outside option. For intermediate values, there is a threshold of tenant ability depending on the outside option level below which the optimal contract is a separating sharecropping contract, and a pooling one otherwise. We also find that an increase in the outside option does not monotonically increase the tenant’s optimal effort.

  • Event Study of the Crude Oil Futures Market: A Mixed Event Response Model
    • Authors: Karali B; Ye S, Ramirez O.
      Pages: 960 - 985
      Abstract: We extend the distributional event response model (DERM) of Rucker, Thurman, and Yoder (2005) in two ways. First, we develop a mixed event response model (MERM) to allow for possible asymmetric effects, and second, we examine how volatility, in addition to return, changes surrounding an event. We apply our model to the crude oil futures market using 25 years of daily data. Our results show that among the 10 events considered, the 2008 global financial crisis had the largest impact in magnitude on both return and volatility. The location and duration of response patterns are also found to vary across different events, with the financial crises having long-lasting impacts, while truly unanticipated events, such as the September 11 terrorist attacks, having short-lived impacts. Results suggest that simply using an event-day dummy variable would hinder discovering overall market responses to slowly evolving information events.
