  • Agricultural (Dis)Incentives and Food Security: Is There a Link'
    • Authors: Magrini E; Montalbano P, Nenci S, et al.
      Pages: 847 - 871
      Abstract: Using the World Bank database “Distortions to agricultural incentives,” this paper analyzes the impact that agricultural (dis)incentives have on food security for a wide sample of countries over the 1990–2010 period. We adopt a continuous treatment approach applying generalized propensity score matching to reduce potential biases stemming from differences in observed country characteristics. The results provide strong evidence of self-selection and heterogeneous food security impacts at different levels of policy intensity. Estimates of the dose-response functions show that both discrimination against agriculture and large support for it lead to poor performance in the availability, access, and utilization dimensions of food security.

           a Link'”
    • Authors: Fan S.
      Pages: 872 - 873
      Abstract: Magrini et al. (2017) analyze the impact of agricultural incentives and distortions on food security (i.e., availability, access, utilization, and stability) using cross-country and time series data for sixty-four countries between 1990 and 2010. The authors use a continuous treatment approach applying generalized propensity-score matching to reduce potential biases stemming from differences in observed country characteristics. Their paper shows robust evidence of self-selection and heterogeneous impacts on food security at different levels of policy intensity. Estimates of the dose-response functions show that both discrimination against agriculture and large support lead to poor food security performance. The study is important and unique in furthering previous research that has attempted to quantify agricultural incentives and analyze policy impacts at the national level. The rigorous quantitative analysis conducted by the authors helps provide a global perspective on the issue of agricultural incentives.

  • Partial Identification Methods for Evaluating Food Assistance Programs: A
           Case Study of the Causal Impact of SNAP on Food Insecurity
    • Authors: Gundersen C; Kreider B, Pepper JV.
      Pages: 875 - 893
      Abstract: We illustrate how partial identification methods can be used to provide credible inferences on the causal impacts of food assistance programs, focusing on the impact that the Supplemental Nutrition Assistance Program (SNAP, formerly known as the Food Stamp Program) has on food insecurity among households with children. Recent research applies these methods to address two key issues confounding identification: missing counterfactuals and nonrandomly misclassified treatment status. In this paper, we illustrate and extend the recent literature by using data from the Survey of Income and Program Participation (SIPP) to study the robustness of prior conclusions. The SIPP confers important advantages: the detailed information about income and eligibility allows us to apply a modified discontinuity design to sharpen inferences, and the panel nature allows us to reduce uncertainty about true participation status. We find that SNAP reduces the prevalence of food insecurity in households with children by at least six percentage points.

  • Efficiency-Equity Tradeoffs in Targeting Payments for Ecosystem Services
    • Authors: Wu J Yu J.
      Pages: 894 - 913
      Abstract: This article develops an analytic framework to analyze the tradeoff between economic efficiency and distributional equity in targeting payments for ecosystem services (PES). It also proposes an empirical procedure to trace out the efficiency-equity frontier, where the program is Pareto optimal in the sense that it cannot be improved upon to achieve either higher efficiency or distributional equity without compromising the other. We apply the procedure to the Conservation Reserve Program (CRP), the largest PES program in U.S. history, to analyze (a) whether it is possible to improve both the efficiency and the distributional equity of the program, and (b) what the choice made by CRP administrators implies about the political-economic balance. Results reveal that (a) CRP administrators forfeited about 9% of efficiency for an 18%–23% improvement in distributional equity, depending on the equity indicator used, in the eighteenth signup of the CRP; (b) reducing the maximum allowable rental rate for all contracts would improve efficiency at the cost of distributional equity; (c) reducing the maximum county enrollment cap would reduce efficiency without generating much improvement in distributional equity; and (d) the CRP targeting criterion could be redesigned to achieve both higher efficiency and higher distributional equity.

  • Addressing Participant Inattention in Federal Programs: A Field Experiment
           with The Conservation Reserve Program
    • Authors: Wallander S; Ferraro P, Higgins N.
      Pages: 914 - 931
      Abstract: Voluntary land conservation programs depend upon the willingness of land owners to participate. Since participation requires commitment to long-term contracts, most studies on participation focus on changes to the pecuniary incentives facing land owners. This study presents a large-scale field experiment within the USDA’s Conservation Reserve Program (CRP) that examines whether informational outreach, including behavioral nudges, could improve land owners’ willingness to participate. The experiment evaluates the impact of three types of reminder letters on the rate at which land is offered into the CRP. We find that for the most well-informed group, farms with expiring CRP contracts, the reminder letters did improve participation. We interpret this result as evidence of inattentive behavior. We do not detect any differences in the estimated treatment effects among the basic reminder letter and the letters augmented with peer comparisons and social norm messaging, nor do we detect any treatment effect among currently unenrolled farms. From a policy perspective, these results imply that the USDA can generate additional CRP offers among farms with expiring contracts at an average cost of $39 per additional offer. Assuming a twenty-five million acre program, reminder letters sent during every sign-up period would result in re-enrollment offers from an additional 420,000 acres. Using simulations based on offers from prior CRP sign-ups, we estimate that these additional offers in the CRP auction would reduce program costs. Depending on the year of simulation, the outreach effort achieves a benefit-cost ratio of between 20:1 and 90:1.

  • Knowledge Measurement and Productivity in a Research Program
    • Authors: Qin L; Buccola ST.
      Pages: 932 - 951
      Abstract: We introduce a metric based on Bayesian probability theory to evaluate the determinants of scientific discovery, and use it to assess an international aquacultural research program consisting of a large number of highly varied projects. The metric accommodates not only project variety but a detailed breakdown of the sources of research productivity, accounting, for example, for the contributions of “failed” as well as “successful” investigations. A mean-absolute-deviation loss functional form permits decomposition of knowledge gain into an outcome probability shift (mean surprise) and outcome variance reduction (statistical precision), allowing productivity to be estimated for each of them separately, then combined into a single knowledge production relationship. Laboratory size is found to moderately boost mean surprise but has no effect on statistical precision, while investigator education greatly improves precision but has no effect on mean surprise. Returns to research scale are decreasing in the size dimension alone but increasing when size and education are taken together, suggesting the importance of measuring human capital at both the quantitative and qualitative margins.

  • Influence of Neighbor Experience and Exit on Small Farmer Market
    • Authors: Michelson HC.
      Pages: 952 - 970
      Abstract: This research analyzes the motivations and dynamics of small farmer participation in supermarket supply chains in developing countries: why some small farmers join these new markets and continue their participation; why others drop out or decline the relationship from the outset. Drawing on insights from the technology-adoption literature on learning and experimentation, and also on findings from a simple two-period Bayesian model of farmer decisions to participate in a new market, we incorporate measures of neighboring farmers’ experience into the decision model. Results suggest that farmers delay entry to observe their neighbors’ outcomes; we find a negative relationship between the number of neighbor participants in a given period and a farmer’s own decision to enter the supply chain. We find evidence that farmers delay entry for strategic reasons, allowing neighbors to bear the costs associated with a first wave of adjustment to the market, including higher product rejection rates and lower initial annual transactions with supermarkets, compared to revenues from marketing in the traditional way. Results are robust to definitions of neighbors using both administrative and geographic designations. Our results raise questions about the optimal sequence and level of farmers' market participation and exit, which remain largely unexplored in the literature.

  • The Welfare Economics of “Buy Local”
    • Authors: Winfree J; Watson P.
      Pages: 971 - 987
      Abstract: This paper provides a theoretical model of how various aspects of the “buy local” movement influence social welfare and output across two regions. Market power considerations are also addressed where one region has a competitive advantage in production. While consumers buy local for a variety of reasons, our model categorizes some of the motivations and analyzes the impacts on output under various market structures. Welfare is calculated when demand is changed due to subsidies or taxes. We also allow for the presence of externalities. We find that, in the absence of market power or externalities, deadweight losses occur when the region without a competitive advantage buys more locally. However, in the presence of significant externalities and in the presence of market power, it is possible that profits to producers from consumers buying local could increase more than consumer utility is harmed, thus increasing aggregate social welfare. This could arise if consumers genuinely feel there are sufficient positive externalities from local production or negative externalities from non-local production to warrant the loss of efficiency. We point out that understanding the motivation behind the movement is critical when analyzing welfare effects since some motivations are counter-productive to each other.

  • Who Cares What Others Think (or Do)' Social Learning and Social
           Pressures in Cotton Farming in India
    • Authors: Maertens A.
      Pages: 988 - 1007
      Abstract: This paper examines the role that social networks play in the adoption process of Bacillus thurigiensis (Bt) cotton, a type of genetically engineered cotton that has been available on the Indian market since 2002. Using a unique dataset and empirical methodology, I find that farmers appeared to have exclusively learned from the experimentation of a small set of “progressive” farmers in the village, that is, adoption by other (“regular”) farmers was not considered a useful source of information about the technology. Second, I find evidence of social pressures, originating from the belief that Bt cotton might be hazardous to the environment and livestock, which inhibited adoption, at least for some time.

  • Spatial Patterns of Market Participation and Resource Extraction: Fuelwood
           Collection in Northern Uganda
    • Authors: Miteva DA; Kramer RA, Brown ZS, et al.
      Pages: 1008 - 1026
      Abstract: While distance to markets is a key determinant of market participation for households that are dependent on natural resources, the distance to the resource stock is also essential. Thus, a household’s location with respect to markets and the resource stock determines household market participation and associated resource degradation. Applying a discrete-choice framework for fuelwood collection in a developing country, we characterize the spatial pattern of market participation regimes and forest use. All else being equal, autarkic households are closest to the forest and furthest from the market, buyer households are closest to the market and furthest from the forest, and seller households are at intermediate distances. Empirical tests based on survey data from northern Uganda support the predictions from our theoretical model. Our findings have important implications for understanding the spatial patterns of forest degradation and determining the control group when designing impact evaluations of the effectiveness of development and conservation interventions.

  • Balancing the Health Risks and Benefits of Seafood: How Does Available
           Guidance Affect Consumer Choices'
    • Authors: Uchida H; Roheim CA, Johnston RJ.
      Pages: 1056 - 1077
      Abstract: Seafood species vary in their health benefits (e.g., from omega-3 fatty acids) and risks (e.g., from methylmercury or polychlorobiphenyls). Reflecting these risks and benefits, multiple public and private organizations offer guidance to consumers on seafood consumption. The effect of this guidance is unknown; previous literature has been unable to disentangle the effects of messages with differing health information, provided by different sources, on demand for different types of seafood. The result is ambiguity regarding the drivers of observed changes in seafood demand. This study investigates the effect of health risk and benefit information on preferences for wild and farmed salmon and swordfish, three species targeted by consumer guidance. The analysis applies an experimental auction with seafood consumers informed by a Bayesian risk-learning model. The model provides a systematic way to disentangle effects on seafood demand, for example, by evaluating whether changes in demand for different species are due to information content or source. Using this approach, we test the effect of guidance provided by four different public and private groups in the United States. Difference-in-difference tests find no impact of health benefit information regardless of source or message, but find multiple effects of health risk information that vary across different types of guidance. These findings suggest that current guidance does not improve consumers’ ability to balance health risks and benefits. We also identify potential avenues to improve the efficacy of this guidance.

  • Expected Product Market Reforms and Technology Adoption by Senegalese
           Onion Producers
    • Authors: Bernard T; de Janvry A, Mbaye S, et al.
      Pages: 1096 - 1115
      Abstract: We assess the responsiveness of Senegalese onion producers to their knowledge of expected changes in product market conditions, whereby onions would no longer be sold based on volume but rather on weight and with labeling certifying quality. A village-level randomized information campaign on the upcoming introduction of these reforms induced significant investments by farmers into quality-enhancing inputs. Delays in the actual introduction of scales enabled us to rigorously identify positive price effects from these investments. Our results point to the importance of farmers’ expectations regarding the improved functioning of product markets in triggering technology adoption.

  • Commodity Storage and the Market Effects of Biofuel Policies
    • Authors: Carter CA; Rausser GC, Smith A.
      Pages: 1027 - 1055
      Abstract: Legislation passed in 2007 by the U.S. Congress increased by about 1.3 billion bushels the net amount of corn required to be processed annually into ethanol for motor-fuel use. We estimate that corn prices were about 30% higher from 2006 to 2014 than they would have been without this demand increase. We develop a partially identified structural vector autoregression model. Our identification strategy is unique in the literature because it enables us to estimate the effects of transitory shocks, such as weather, separately from the effects of persistent shocks, such as the increased ethanol mandate. Moreover, by only partially identifying our model, we show how to generate robust conclusions without strong identifying assumptions.

  • Modeling the Interplay between Sanitary and Phytosanitary Measures and
           Tariff-rate Quotas under Partial Trade Liberalization
    • Authors: Beckman J; Arita S.
      Pages: 1078 - 1095
      Abstract: Non-tariff measures, particularly sanitary and phytosanitary measures and tariff-rate quotas, are two critical policy barriers that impede agricultural trade. Unlike simple tariffs, both measures contain non-linear effects and binding conditions that make their treatment in modeling trade liberalization challenging. In addition, the coexistence of these measures carries important interactive effects that restrict trade. This study investigates these joint effects by developing a conceptual framework that considers different partial liberalization scenarios. Our framework points to three cases that may arise: (a) binding tariff-rate quota, non-prohibitive sanitary and phytosanitary measure; (b) non-binding tariff-rate quota, non-prohibitive sanitary and phytosanitary measure; and (c) non-binding tariff-rate quota, prohibitive sanitary and phytosanitary measure. We then use a Computable General Equilibrium model to examine partial trade liberalization scenarios for these cases, using the ongoing Transatlantic Trade and Investment Partnership negotiations as our motivation. Our simulations provide a more nuanced analysis of complex trade liberalization and demonstrate the importance of modeling the interplay between these different types of barriers.
