  • Efficiency Impacts of Utilizing Soil Data in the Pricing of the Federal
           Crop Insurance Program
    • Authors: Woodard JD; Verteramo-Chiu LJ.
      Abstract: AbstractSince the Agricultural Act of 2014, the federal crop insurance program (FCIP) has been the cornerstone agricultural policy in the United States, and is the largest such program globally, with about $100 billion in coverage annually. Given its scale and scope, the FCIP has the potential to have pervasive impacts on incentives and policy functioning if not designed and priced properly. Surprisingly, soil data are not considered by the government when establishing insurance guarantees or rates. Using soil data that could easily and feasibly be scaled nationally, we find that the pricing differentials caused by the government's failure to handle soil information leads to large errors in rating.

  • Retail Intermediation and Local Foods
    • Authors: Richards TJ; Hamilton SF, Gomez M, et al.
      Abstract: AbstractDirect sales of local foods, for instance through farmer’s markets, have reached a plateau, while intermediated sales (through more traditional retailers) are still rising rapidly. We provide an explanation for the growth of intermediated local foods based on the observation that consumers prefer to buy local foods as part of a shopping basket that includes both local and non-local items. We test our hypothesis using data from a natural experiment conducted by Relay Foods, an online retailer based in the U.S. state of Virginia, and a multi-variate logit model of shopping-basket demand. We find significant complementarities among items in a sample shopping basket that are not reflected in estimates from a discrete-choice model of category demand. Estimates of a structural pricing-and-local-content model reveal important incentives for retailers to offer local foods as part of a broader selection of grocery items.

  • Market Institutions and Price Relationships: The Case of Coffee in the
           Ethiopian Commodity Exchange
    • Authors: Hernandez MA; Rashid S, Lemma S, et al.
      Abstract: AbstractWhile the Ethiopian Commodity Exchange (ECX) is widely considered a successful market institution, very little rigorous empirical investigation has been done on it. This paper contributes to filling this knowledge gap. Using a unique set of spatially disaggregated prices for five different coffee varieties, we examine how the ECX has influenced the dynamics of international and domestic prices for coffee, the largest traded commodity in terms of trade value on the exchange floor. We follow a multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) approach to assess the extent of market interdependence (conditional correlations) and volatility transmission. We also evaluate structural changes in price dynamics over time. Our results suggest that, contrary to popular media stories, the ECX’s success in strengthening coffee price relationships has been limited. We discuss the underlying reasons and implications of this finding.

  • Quality Information and Procurement Auction Outcomes: Evidence from a
           Payment for Ecosystem Services Laboratory Experiment
    • Authors: Conte MN; Griffin RM.
      Abstract: AbstractProcuring agencies in conservation auctions typically have more information about the ecosystem service (ES) quality of conservation actions than landowners and can affect auction outcomes by controlling participants’ access to this information. Our induced-value laboratory auction experiment explores the impact of sellers’ access to ES-quality information on auction efficiency when the conservation action choice is endogenous to offer formation. We find that providing ES-quality information allows sellers to identify and submit higher-quality conservation actions, an effect that counteracts previously identified efficiency losses from information rents.

  • Listing and Delisting Thresholds under the Endangered Species Act
    • Authors: Sims C; Finnoff D, Hastings A, et al.
      Abstract: AbstractWe consider the case where a species provides a flow of economic benefits, is at risk of extinction, and is being considered for addition to the Endangered Species List. Listing a species as endangered is costly but increases the flow of social benefits and reduces the likelihood of extinction. If the species recovers sufficiently, additional costs can be incurred to subsequently delist the species. By treating listing and delisting as a pair of linked investment options, we provide an alternative to current practice for listing and delisting decisions that maximizes the return from public conservation investments. Under this alternative framework, we show that economic considerations may actually afford greater protection for at-risk species if these decisions are initiated early. However, biological sources of uncertainty may cause those species most in need of protection to be passed over in favor of more stable species that represent a “sure bet” for species preservation.

  • The Political Economy of Fertilizer Subsidy Programs in Africa: Evidence
           from Zambia
    • Authors: Mason NM; Jayne TS, van de Walle N.
      Abstract: AbstractFertilizer subsidy programs have re-emerged as popular policy tools in sub-Saharan Africa. Despite a burgeoning body of literature on program impacts, the political economy of the programs remains poorly understood. In particular, there is a dearth of empirical evidence to support or refute the conventional wisdoms that governments systematically target subsidized inputs to certain areas based on past voting patterns and that fertilizer subsidies win votes. This article discusses the theoretical links between government targeting of subsidized fertilizer and voter behavior, then uses panel data from Zambia to empirically test these conventional wisdoms. Results suggest that Zambia’s Movement for Multi-Party Democracy governments targeted more subsidized fertilizer to households in areas where it had strong support in the previous presidential election. However, contrary to conventional wisdom, marginal changes in the scale or coverage of the fertilizer subsidy program had no statistically significant effect on the share or number of votes won by incumbent presidents.

  • Re-Examining the Reported Rates of Return to Food and Agricultural
           Research and Development: Comment
    • Authors: Oehmke JF.
      Abstract: AbstractHurley, Rao, and Pardey (2014) argue to replace the internal rate of return with the modified internal rate of return for the evaluation of public research investment. The crux of their argument is that the internal rate of return “assumes intermediate cash flows can be reinvested (or borrowed) at same return as the initial investment, which is generally not correct or reasonable,” (page 1492). This article first demonstrates that reinvestment decisions are embodied in the project specification, and that the internal rate of return makes no inherent reinvestment assumption. The article then clarifies the algebraic properties of the marginal internal rate of return and the reinvestment implications of the internal rate of return and modified internal rate of return within the context of public agricultural research evaluation.

  • Re-Examining the Reported Rates of Return to Food and Agricultural
           Research and Development: Reply
    • Authors: Hurley TM; Rao X, Pardey PG.
      Abstract: AbstractHurley, Rao and Pardey (2014) analytically and empirically evaluate the internal rate of return (IRR) vis a vis the modified internal rate of return (MIRR) for investments in agricultural research and development (R&D). They find that estimates of the IRR are 2.5 to 5 times larger than the MIRR for a wide range of assumptions, leading them to question the value of the IRR as a metric to represent the rate of return to agricultural R&D. Oehmke (2016) defends the IRR by arguing that it has important properties that the MIRR does not possess. In this article, we critically examine these properties demonstrating that some are not inherent to the MIRR. For other properties, we simply disagree with Oehmke’s assessment of their desirability. Therefore, we are not compelled to change our original recommendation.

  • The Effects of Development Constraints on Forest Management at the
           Urban-Forest Interface
    • Authors: Cunha-e-Sá MA; Franco SF.
      Abstract: AbstractThis article develops a model of a forest owner operating in a small, open-city environment where the rent for developed land is increasing concave in nearby preserved open space and is rising over time, reflecting an upward trend in households’ income. Within this framework we examine how changes in nearby preserved open space and alternative development constraints affect an individual private landowner's decisions regarding both regeneration harvests and conversion dates. We also examine how such policies affect development density once conversion from forestry to residential use occurs. We show that when residential rents change over time, the nature of the timber problem at the urban-forest interface changes because it forces us to allow for the possibility of changes in land use from timber to residential use. As a result, the traditional Faustmann setup is not suitable to study forest management decisions at this interface. We also find that in the presence of rising income, increases in permanently preserved open space hasten regeneration and conversion cuts of a neighboring parcel currently under forest use and leads to lower density development once conversion takes place compared to the case where income is constant. We also find that both a binding development moratorium and a binding minimum-lot-size policy can postpone regeneration and conversion cut dates and thus help to protect open space, even if only temporarily. However, the policies do not have the same effects on development density of converted forestland. While the former leads to high-density development, the latter encourages low-density development.

  • Markets, Transportation Infrastructure, and Food Prices in Nepal
    • Authors: Shively G; Thapa G.
      Abstract: AbstractWe study transportation infrastructure and food markets in Nepal over the period 2002 to 2010, combining monthly price data from thirty-seven local and regional markets, and seven Indian border markets. We use a series of autoregressive models to study price determination, spatial and temporal price transmission, and price variance. We account for district-level agricultural production, correcting for bi-directional causality between output and prices using ground station rainfall data. In addition, to test hypotheses regarding the importance of transportation infrastructure we incorporate information on road and bridge density and fuel costs. For both rice and wheat, we find strong evidence of local price intertemporal carryover and very weak evidence of price transmission from regional, central, and border markets to local markets, suggesting very low degrees of market integration. Fuel costs are positively correlated with food prices, and road and bridge density are negatively correlated with prices. We find evidence of asymmetric effects: positive price shocks are correlated with higher subsequent price volatility compared with negative price shocks of similar magnitude. Roads and bridges are important for moderating price levels and price volatility in Nepal’s rice and wheat markets, which explains roughly half of the spatial and temporal variation in price mark-ups between regional and local markets.

  • Testing for Specification Bias with a Flexible Fourier Transform Model for
           Crop Yields
    • Authors: Cooper J; Nam Tran AA, Wallander S.
      Abstract: AbstractThe literature on climate risk and crop yields is currently focused on the potential for highly non-linear marginal effects, essentially modeling the threshold effects with a yield function that maps weather inputs into crop yields. Implicit in this line of research is the assertion that the traditional quadratic model of crop yield suffers from specification bias. This article examines this assumption by using the Flexible Fourier Transforms (FFT) to allow for global flexibility in the weather effects while also maintaining the traditional quadratic model as a nested model specification. In order to speak to the global flexibility of FFT, as well as to provide both robustness to outliers and information on the scale effects of weather variables, this article compares FFT with restricted cubic spline (RCS) and quadratic models in a quantile regression framework. Using U.S. county-level data on corn, soybeans, and winter wheat from 1975 to 2013, we find that while the threshold effects are largely captured by the traditional quadratic model, we statistically reject the hypothesis that the quadratic model is sufficiently flexible. We find that, under the more flexible FFT functional forms, at lower temperatures there is a greater positive impact of marginal increases in temperature on yield than with the quadratic model, which suggests a different yield-temperature relationship than found in much of the literature on threshold effects of temperature on crop yields, and is more consistent with the positive effects of minor temperature increases found in some of the Ricardian climate effect literature.

  • Impacts of Federal Crop Insurance on Land Use and Environmental Quality
    • Authors: Claassen R; Langpap C, Wu J.
      Abstract: AbstractThis article integrates economic and biophysical models to assess how federal crop revenue insurance programs affect land use, cropping systems, and environmental quality in the U.S. Corn Belt region. The empirical framework includes econometric models that predict land conversion and crop choices at the parcel level based on expectation and variance of crop revenues, land quality, climate conditions, and physical characteristics at each site. The predictions are then combined with site-specific environmental production functions to determine the effect of revenue insurance on nitrate runoff and leaching, soil water and wind erosion, and carbon sequestration. Results suggest that federal crop insurance has, on average, a small effect on conversions of non-cropland to cropland, and somewhat more significant impacts on crop choice and crop rotation. These changes in cropping systems have, on average, small impacts on agricultural pollution.

  • Subsidies and Technical Efficiency in Agriculture: Evidence from European
           Dairy Farms
    • Authors: Latruffe L; Bravo-Ureta BE, Carpentier A, et al.
      Abstract: AbstractThe objective of this article is to examine the association between agricultural subsidies and dairy farm technical efficiency in the European Union, and in so doing we make novel contributions to the literature. We include in the analysis nine diverse western European Union (EU) countries over an 18-year period (1990–2007) encompassing the various Common Agricultural Policy (CAP) reforms enacted since the inception of the EU. Further, we account for input endogeneity using an original method of moments estimator. Our results show that the effect of subsidies on technical efficiency may be positive, null, or negative, depending on the country. The analysis reveals that the introduction of decoupling with the 2003 CAP reform weakens the effect that subsidies have on technical efficiency.

  • Rationality of Choices in Subsidized Crop Insurance Markets
    • Authors: Du X; Feng H, Hennessy DA.
      Abstract: AbstractThe U.S. crop insurance market has several features that set it apart from other insurance markets. These include explicit government subsidies with an average premium subsidy rate of about 60% in recent years, and the legislative requirement that premium rates be set at actuarially fair levels, where the federal government sets rates and pays all costs related to insurance policy sales and services. Bearing these features in mind, we examine the extent to which farmers’ crop insurance choices conform to economic theory. A standard expected utility maximization framework is constructed to analyze trade-offs between higher risk protection and larger subsidy payments. We decompose the effect of coverage level on expected utility into insurance, premium loading, and subsidy transfer effects where the loading effect vanishes if rates are actuarially fair. Given an actuarially fair premium, we infer that a rational farmer should choose either the coverage level with the highest premium subsidy or a higher coverage level. Evidence from a large insurance unit-level dataset contradicts this theoretical inference, and so suggests anomalous insurance decisions. In a novel application of the mixed logit framework, we show that the probability an insurance product is chosen declines as out-of-pocket premium expenditures increase, even though higher values of these expenditures should reflect improved grower welfare. Premium expenditures appear to be more salient than the uncertain future benefits they support. We apply our regression to the recent trend yield adjustment innovation in crop insurance.

  • “Decoupled” Farm Program Payments are Really Decoupled: The
           Theory
    • Authors: Chambers RG; Voica DC.
      Abstract: AbstractLump-sum transfers to farmers are commonly believed to affect the production choices of farmers in the presence of risk and uncertainty. This paper shows that if farmers have off-farm investment and employment opportunities, production decisions are decoupled from lump-sum subsidies in the presence of risk and uncertainty. Our results are reconciled with existing results by showing that previously identified production adjustments are portfolio adjustments.
