  • Estimating the Productivity Impacts of Technology Adoption in the Presence
           of Misclassification
    • Authors: Wossen T; Abdoulaye T, Alene A, et al.
      Pages: 1 - 16
      Abstract: This article examines the impact that misreporting adoption status has on the identification and estimation of causal effects on productivity. In particular, by comparing measurement error-ridden self-reported adoption data with measurement-error-free DNA-fingerprinted adoption data, we investigate the extent to which such errors bias the causal effects of adoption on productivity. Taking DNA-fingerprinted adoption data as a benchmark, we find 25% “false negatives” and 10% “false positives” in farmers’ responses. Our results show that misreporting of adoption status is not exogenous to household characteristics, and produces a bias of about 22 percentage points in the productivity impact of adoption. Ignoring inherent behavioral adjustments of farmers based on perceived adoption status has a bias of 13 percentage points. The results of this article underscore the crucial role that correct measurement of adoption plays in designing policy interventions that address constraints to technology adoption in agriculture.

  • Comment on “Estimating the Productivity Impacts of Technology Adoption
           in the Presence of Misclassification”
    • Authors: Macours K.
      Pages: 17 - 18
      Abstract: Wossen et al. (2018) puts the spotlight on an important, and until recently underestimated, phenomenon: farmers in developing countries may often misreport whether the crop varieties they grow are improved or not. Given the key role of improved varieties in the green revolution, and ongoing debates on whether productivity gains can still be achieved and reach areas of the developing world where diffusion of improved varieties has been limited, establishing reliable empirical evidence regarding the levels of adoption of improved varieties is a first-order priority.

  • “Estimating the Productivity Impacts of Technology Adoption in the

    • Authors: Wossen T; Abdoulaye T, Alene A, et al.
      Pages: 19 - 19
      Abstract: We thank Karen Macours for her insightful comments on our article. While we agree with many of her suggestions, we wish to respond to three main points: (a) the measurement and relevance of the instruments, (b) the exogeneity of instruments and interpretation of results, and (c) the interpretation of behavioral adjustment effects.

  • The Economics of Food Vendors Specialized to Serving the Women, Infants,
           and Children Program
    • Authors: McLaughlin P; Saitone T, Sexton R.
      Pages: 20 - 38
      Abstract: This paper focuses on the impacts of food vendors that have emerged primarily or exclusively to redeem benefits for the Women, Infants and Children (WIC) Program. Federal regulations impose strict requirements on state WIC agencies which authorize vendors that derive more than 50% of their food sales through WIC. Such vendors are commonly known as above-50 or A50 vendors, and most state WIC agencies do not authorize them. Using extensive transactions-level data for the Greater Los Angeles area (GLA), we examine A50 vendors’ performance in the WIC program, including their pricing behavior relative to other WIC vendors in a but-for world where A50 vendors are not authorized. We also conduct econometric tests designed to gauge A50 vendors’ impacts on WIC program access and participation, and costs charged for WIC foods by other program vendors. Results indicate that A50 vendors operating in GLA (a) modestly reduced WIC program food costs relative to a but-for world where they were not authorized, (b) had a modest pro-competitive effect on the pricing behavior of small, non-A50 vendors, which have tended to charge the highest absolute prices for WIC foods in California, (c) caused a modest reduction in participant travel distance (and, hence, transaction costs), and (d) appear to have facilitated participant access. On balance, our results suggest that A50 vendors can improve the food-delivery environment for the WIC program and facilitate participant access to WIC benefits without imposing additional food costs on the program.

  • Breakfast at School: a First Look at the Role of Time and Location for
           Participation and Nutritional Intake
    • Authors: Moeltner K; Spears K, Yu L.
      Pages: 39 - 57
      Abstract: Participation in the subsidized School Breakfast Program has traditionally been unsatisfactory. Universally free breakfast service in the classroom has boosted participation, but is not financially feasible for many schools. Furthermore, it is unclear to what extent participation under the standard cafeteria setting is hampered due to insufficient time to eat. This study separately identifies time and location effects using a unique, individual-level panel data set of elementary school students under three experimental treatments: original setup in the cafeteria, original setup plus ten minutes of mandatory presence in the cafeteria, and in-classroom service. We find that the extra time plus the fixed location effect in the cafeteria increases average daily participation by approximately 20%, while the transition to classroom implementation adds another 35%–45% for the typical student. We also collect detailed data on nutritional intake, and find that, in total, neither treatment has a significant effect on consumption compared to the baseline.

  • Impacts of Mandatory GE Food Labeling: A Quasi-Natural Experiment
    • Authors: Carter C; Schaefer K.
      Pages: 58 - 73
      Abstract: In July 2016, Vermont became the first U.S. state to require mandatory labeling of foods containing genetically engineered (GE) ingredients. The introduction of the Vermont law serves as a quasi-natural experiment on the economic effects of mandatory GE labeling. We investigate the market response in the U.S. sugar market. Almost all beet sugar is GE, while cane sugar is GE-free. Prior to 2016, cane and beet sugar were regarded as homogenous. However, in mid 2016, refined cane sugar began selling at a premium over refined beet sugar. We find the mandatory labeling initiative generated about a 13% price discount for beet sugar and a premium of about 1% for cane. Food manufacturers’ concerns over mandatory labeling caused them to switch inputs. This resulted in a redistribution of welfare in the U.S. sugar industry.

  • Choosing Certifiers: Evidence from the British Retail Consortium Food
           Safety Standard
    • Authors: Bar T; Zheng Y.
      Pages: 74 - 88
      Abstract: Standards play a vital role in promoting food safety, and in many countries third-party certification bodies carry out audits to determine if food manufacturers comply with a particular standard. Using data from the British Retail Consortium global standards program, we study manufacturers’ choices of certification bodies. We take a certification body’s share of high audit grades in the months preceding an audit as a measure of perceived leniency, and find that manufacturers are more likely to choose certification bodies that they perceive to be more lenient. Manufactures are also more likely to choose geographically closer certification bodies, and to return to the same certifier that audited their site in the previous year.

  • Free-riding on Product Quality in Cooperatives: Lessons from an Experiment
    • Authors: Bonroy O; Garapin A, Hamilton S, et al.
      Pages: 89 - 108
      Abstract: An important issue facing marketing cooperatives is that the overall quality of the product depends on the quality of farm products provided by individual members. We conduct an experiment to empirically investigate producer incentives to free-ride on quality among the members of a marketing cooperative in a setting where the average quality provided by cooperative members results in a collective rent that is distributed back to members in a patronage dividend levied in proportion to the quantity produced. Hidden actions by cooperative members that impact quality are imperfectly monitored, but free-riding, when detected, results in exclusion from cooperative returns. The randomized payoff structure of our game results in a novel experimental design that nests public good games and multi-player assurance games. Our findings indicate that free-riding on product quality is deterred when (a) cooperatives base patronage dividends on quality outcomes of smaller groups; (b) payoffs from free-riding are randomized by the possibility of exclusion from cooperative returns; and (c) cooperatives distribute a larger share of returns to members through indirect payments such as capital pooling and cost-sharing arrangements unrelated to product quality.

  • Experimental Evidence on Policy Approaches That Link Agricultural
           Subsidies to Water Quality Outcomes
    • Authors: Palm-Forster L; Suter J, Messer K.
      Pages: 109 - 133
      Abstract: Improving water quality in agricultural landscapes is an ongoing challenge, and most agri-environmental programs in the United States rely on voluntary adoption of conservation practices. Conservation-compliance initiatives require producers to meet specific conservation standards to qualify for payments from farm programs. However, these requirements do not require actual improvements in observed water quality. In this study, we introduce policies to reduce nonpoint source pollution that link eligibility for agricultural subsidies to compliance with water quality goals. We then use economic laboratory experiments to provide empirical evidence related to the performance of these policies. In the policy treatments, participants risk losing some or all of their subsidies if the ambient pollution level exceeds an announced target. A novel feature of our experiment is that we test a policy treatment that ensures that no subsidies are lost if a producer implements a verifiable conservation technology that reduces emissions. In these experiments, policies that link the receipt of subsidies to ambient water quality nearly achieve the socially optimal level of pollution. The results suggest that water quality policies that rely on the threat of subsidy reductions are a potentially viable option for reducing aggregate water pollution. Although a policy that allows polluters to avoid potential losses by implementing a verifiable conservation technology could increase political support for ambient-based policies, our results suggest that, depending upon the magnitudes of social damages from emissions and the cost of implementing a conservation technology, such policies may be less cost-effective for a comparable reduction in pollution.

  • Agricultural Water Allocation under Uncertainty: Redistribution of Water
           Shortage Risk
    • Authors: Li M; Xu W, Zhu T.
      Pages: 134 - 153
      Abstract: This article develops an economic model to analyze how the risk of water shortages affects farmers’ land irrigation decision and how the priority-based water sharing arrangement redistributes such a risk among farms with different water rights priorities. The analysis brings together an array of comprehensive data files on irrigation rights, water supplies, and agricultural land use from eastern Idaho. Results indicate that a more left-skewed distribution of streamflow significantly discourages land irrigation among farmers except the most senior rights holders. The priority-based water sharing arrangement redistributes the macroscale risk of water shortages and thus exposes farmers of different water rights priorities to heterogeneous levels of risk: senior water rights holders are affected the least and such a risk is instead passed mostly on to junior water rights holders. The role of water rights in risk redistribution is more significant when the probability distribution of water shortage risk is asymmetric rather than symmetric. The historical development pattern of water rights influences how the priority of water rights takes effect on land irrigation decision.

  • The Role of Peer Effects in Natural Resource Appropriation – The
           Case of Groundwater
    • Authors: Sampson G; Perry E.
      Pages: 154 - 171
      Abstract: Spatially mediated peer effects are increasingly recognized as an important driver of technology adoption. In this paper, we isolate the role of peer effects from environmental factors in the acquisition of groundwater rights for agricultural irrigation in Kansas. We find strong evidence of peer effects influencing farmers’ decisions to adopt groundwater irrigation. Using a rich dataset on groundwater rights for the period 1943–2014 and a nearest neighbor peer group definition, we find that one additional neighbor adopting groundwater for irrigation increases groundwater adoption by an average of 0.25 percentage points. We also find that the average marginal effect of one additional peer is reduced by distance and diminishes as the total number of neighbors adopting groundwater increases. Using our model estimates to simulate a counterfactual without peer effects, we find that water rights appropriation stemming from peer effects accounted for about 11 million acre-feet of extraction from the Kansas High Plains Aquifer. This amounts to about three years of typical annual extraction. Our results provide evidence that peer effects can “speed up” resource extraction and can help inform policy makers in designing exploitation control rules.

  • Two Harvests Are Better than One: Double Cropping as a Strategy for
           Climate Change Adaptation
    • Authors: Kawasaki K.
      Pages: 172 - 192
      Abstract: Adaptation of agriculture to climate change is essential for reducing its negative impacts. This article evaluates the feasibility of double cropping, which has received relatively little consideration yet holds potential as an adaptation strategy. To assess its feasibility, growing seasons and economic profitability as calculated from crop yield and quality are considered. Accordingly, methods are developed for quantifying the determinants of crop yield and quality grade in a simultaneous equation system that directly expresses the ordered and fractional nature of grade shares. An empirical application to rice and wheat production in Japan reveals that, without any adaptation strategy, climate change will decrease revenues of both crops due to the reduction in yield and quality. Adjusting planting dates helps to avoid such negative impacts for rice but not enough for wheat in southern Japan. However, climate change provides an opportunity for another adaptation strategy—double cropping. Warmer climates enable many regions to shift from a single cropping system to a rice-wheat double cropping system by shortening the length of the wheat growing season and by delaying the optimal timing of rice planting. As a consequence, the area suitable for double cropping is nearly tripled, suggesting a strong potential to offset climate-induced production and profit losses.

  • Estimating the Impact of Drought on Agriculture Using the U.S. Drought
    • Authors: Kuwayama Y; Thompson A, Bernknopf R, et al.
      Pages: 193 - 210
      Abstract: We estimate the impacts of drought, as defined by the U.S. Drought Monitor (USDM), on crop yields and farm income in the United States during the 2001–2013 time period. Our empirical strategy relies on panel data models with fixed effects that exploit spatial and temporal variability in drought conditions and agricultural outcomes at the county level. We find negative and statistically significant effects of drought on crop yields equal to reductions in the range of 0.1% to 1.2% for corn and soybean yields for each additional week of drought in dryland counties, and 0.1% to 0.5% in irrigated counties. Region-specific results vary, with some regions experiencing no yield impacts from drought, while yield reductions as high as 8.0% are observed in dryland counties in the Midwest for every additional week of drought in the highest USDM severity category. Despite this impact on crop yields, we find that additional weeks of drought have little to no effect on measures of farm income. While precipitation and temperature explain most of the variability in crop yields, we find that the USDM captures additional negative impacts of drought on yields.

  • Effectiveness of a REDD+ Project in Reducing Deforestation in the
           Brazilian Amazon
    • Authors: Simonet G; Subervie J, Ezzine-de-Blas D, et al.
      Pages: 211 - 229
      Abstract: We estimate the early effects of the pilot project to Reduce Emissions from Deforestation and forest Degradation (REDD+) in the Brazilian Amazon. This project offers a mix of interventions, including conditional payments, to reduce deforestation by smallholders who depend on swidden agriculture and extensive cattle ranching. We collected original data from 181 individual farmers. We use difference-in-difference (DID) and DID-matching approaches and find evidence that supports our identification strategy. We estimate that an average of 4 ha of forest were saved on each participating farm in 2014, and that this conservation came at the expense of pastures rather than croplands. This amounts to a decrease in the deforestation rate of about 50%. We find no evidence of within-community spillovers.

  • Pollination Markets and the Coupled Futures of Almonds and Honey Bees:
           Simulating Impacts of Shifts in Demands and Costs
    • Authors: Lee H; Sumner D, Champetier A.
      Pages: 230 - 249
      Abstract: Honey bees have garnered much attention in recent years. Concerns about long-term sustainability of pollinator populations have been coupled with concerns about implications for food supplies. We use a novel formulation of a multiple input, multiple output, two season equilibrium simulation model to explore economic linkages across the markets of buyers and sellers of pollination services and honey. We specify and calibrate in a tractable way the empirical relationships between pollinators and the crops they pollinate, especially almonds. Our model highlights the sequential nature of the pollination season and implication for revenue from pollination and honey production. We demonstrate how shifts in almond supply and demand and the much-discussed honey bee hive health problems cause price and quantity adjustments in horizontally and vertically related markets and quantify these effects. We show that the economic fortunes of the almond industry, including demand growth, cost concerns, and the potential for new almond varieties that use fewer bees, crucially affect the returns to beekeeping and the number of hives. These drivers of almond economics also have substantial effects on the cost of pollination for crops that are pollinated later.

  • Agricultural Market Liberalization and Household Food Security in Rural
    • Authors: Baylis K; Fan L, Nogueira L.
      Pages: 250 - 269
      Abstract: In the 1990s, prior to its accession to the World Trade Organization, China dramatically reduced market distortions in agriculture. We use a panel of 6,770 rural households from 1989 to 2000 to ask whether agricultural market liberalization affected rural household food security as measured by the share of calories from non-staples. Given that not all households may be able to take advantage of new market opportunities, we focus on the distributional effect of market liberalization. Unlike most previous research on the effects of liberalization, we consider the effects of liberalization on both farm and off-farm income. We find that liberalization primarily improves household food security by increasing off-farm income, and the effects vary greatly by initial food security status and producer types. While many households benefit from liberalization, some food-insecure households producing import-competing products have lower food security as a result of agricultural market liberalization.

  • Fossil Fuel Subsidy Reforms, Spatial Market Integration, and Welfare:
           Evidence from a Natural Experiment in Ethiopia
    • Authors: Fuje H.
      Pages: 270 - 290
      Abstract: In light of climate change and tight fiscal conditions after the 2008 crises, fuel subsidy reform has become a popular policy. The G20 leaders, in their Pittsburgh, Pennsylvania meeting in 2009, committed to phase out inefficient fuel subsidies. However, little is known about the implications of removing subsidies on food prices and welfare. I study the welfare effects of such reforms through their impacts on the spatial dispersion of food prices using a “natural experiment” from Ethiopia. I employ time-regression discontinuity design using a highly disaggregated monthly grain price data (1996–2013) from 300 locations. I find the following: (a) the reform substantially increased grain price dispersion; (b) there are notable spatial heterogeneities in the treatment effect; (c) even if the reform has had no impact on overall price levels, it increased cross-sectional spatial price differences; and (d) net-sellers of grain in remote districts and some urban households experienced welfare losses.

  • R&D Spending, Knowledge Capital, and Agricultural Productivity
           Growth: A Bayesian Approach
    • Authors: Baldos U; Viens F, Hertel T, et al.
      Pages: 291 - 310
      Abstract: In this article, we employ Bayesian hierarchical modeling to better capture and communicate the uncertainties surrounding the transformation of U.S. public agricultural research and development (R&D) expenditures to knowledge capital stocks as well as its contribution to the historic growth of U.S. agricultural total factor productivity. Compared to studies based on classical statistics, analytical methods grounded in Bayesian inference explicitly incorporate existing information and permit revision of our knowledge regarding the distribution of the unknown model parameters as additional information becomes available. Bayesian hierarchical modeling is particularly useful in statistically estimating the underlying parameters of the R&D lag weight structure, as well as the R&D knowledge stocks given observed data on agricultural productivity and R&D expenditures. Our results show a significant level of uncertainty on the R&D lag weight structure, indicating that published assumptions about the R&D lag structure can now be tested and validated against available data. Estimating the R&D lag weights and knowledge stocks also make a large difference in the uncertainties surrounding economic returns from R&D investments. Indeed, our results show that the best-fit linear model yields slightly higher mean returns to R&D spending relative to the log model results and have significantly less uncertainty. This suggests that marginal returns to U.S. public agricultural research spending might have remained relatively constant despite a century of growth in expenditure. Furthermore, we find that such investments could take a longer time to bear fruit than previously realized.

  • Scanner Data-Based Panel Price Indexes
    • Authors: Zhen C; Finkelstein E, Karns S, et al.
      Pages: 311 - 329
      Abstract: We construct panel price indexes using retail scanner data that allow comparisons of consumption cost across space and time. Two types of panel indexes are examined: the rolling-window panel extensions of the multilateral Cave-Christensen-Diewert index with the Törnqvist index as its elements, and of the multilateral Gini-Eltetö-Köves-Szulc index using the Fisher ideal index as its elements. The rolling window method maintains the nonrevisability of published index numbers while allowing index numbers for new periods and locations to be calculated and the basket of items to be updated. Meanwhile, the multilateral structure of price comparison eliminates significant downward drift in standard chained indexes. Using county-level bilateral and panel indexes based on retail beverage scanner data, we experimentally adjust for purchasing parity the portion of Supplemental Nutrition Assistance Program (SNAP) benefits that participants spend on beverages. Accounting for temporal and spatial cost differences causes over 2% of SNAP allotment spent on beverages to be reallocated, or approximately a 5% change in allotment on average for a county. About 90% of the relocated SNAP fund is to adjust for spatial differences in food cost. We also compare SNAP allotments implied by the retail scanner data indexes with those implied by indexes based on the USDA Quarterly Food-at-Home Price Database (QFAHPD). The treatment of unit values and product quality may have contributed to the significant differences observed between the retail scanner data indexes and the QFAHPD indexes.

  • Using Bayesian Kriging for Spatial Smoothing in Crop Insurance Rating
    • Authors: Park E; Brorsen B, Harri A.
      Pages: 330 - 351
      Abstract: Rating insurance policies depends on the probability of events in the tail of a distribution. A method to measure such tail-related risk based on Extreme Value Theory could potentially improve insurance rating. It is also widely agreed that there is a spatial structure to crop yield distributions. Considering the spatial structure may provide more precisely rated policies. In this context, this research provides two contributions in rating area yield crop insurance. One is to provide a method that fits the tail of crop yield distributions using the Generalized Pareto Distribution (GPD), a member of the family of extreme value distributions that models only the tail of the distribution. The second is to estimate parameters of the distribution using a Bayesian Kriging approach that provides spatial smoothing of GPD parameters. The proposed model provides estimates of the spatial structure across regions such as the maximum distance of the spatial effect. Based on an out-of-sample performance game between a private insurance company and the federal agency the proposed model provides considerable improvement, particularly when rating deeper tail probability.
