This analysis provides two case studies comparing direct payment versus charitable donations on respondents' behalf as survey participation incentives. The first examines agricultural producers' willingness to participate in several hypothetical surveys. Donation to charity significantly increases producers' willingness to participate relative to direct payment. The second case study examines forest landowners' willingness to participate in an actual, one-time survey. Neither payment nor donation incentives improve participation among mail respondents and donations are less effective versus payment among online respondents. If they do not decrease participation, then donations may be preferred, requiring less effort to process a smaller number of transactions.

This study examines the uncertainty-agricultural trade nexus. Uncertainty effects on macroeconomic indicators such as consumption and investment have been well studied. However, less is known about the relationship between uncertainty and international trade, particularly the heterogeneity of that linkage across sectors. Application of a novel data-driven methodology—anomaly detection and classification via a Naïve Bayesian Classifier—to monthly data at the HS-4 level finds that agricultural imports are reduced when economic policy uncertainty is high. The effects of policy-related uncertainty are more persistent than that of supply-side fluctuations. Anticipatory stock-piling occurred when uncertainty is specific to trade policy.

This paper estimates the impact of Brazilian soybean area expansion on US and Brazilian soybean exports to China by projecting these countries’ exports for various Brazilian soybean area growth scenarios. The results indicate that the Brazilian area expansion does not significantly affect US soybean exports to China but positively impacts Brazil's soybean exports to China. Ex-post analysis of the impacts of Chinese tariff during the US–China trade war indicates that China significantly diverted its imports from the United States to Brazil. We conclude that the US soybean trade policy should focus on mitigating the adverse effects of import demand changes.

Producer organizations (POs) receive substantial attention and policy support, given their potential to contribute to pro-poor rural development. Here, we first synthesize decades of empirical research in the form of five stylized facts—common and largely unchallenged conclusions—about POs. Then, we explore these stylized facts using several secondary and primary data sets. We confirm some stylized facts, challenge others, and highlight which ones lack empirical evidence to derive policy implications and directions for future research. We highlight largely overlooked low and regionally biased participation rates and suggest that future research should pay more attention to the diverse forms and characteristics of POs.

This study examines how the political alignments of Midwestern farmers, proxied by their consumption of partisan media, affect their perceptions of and responses to the US–China trade war. Our results indicate that farmers who consume conservative media perceive a lower income loss resulting from the trade war and view the Market Facilitation Program (MFP) as more helpful. Conversely, farmers who consume liberal media have the opposite perception biases. We found no evidence of any association between partisan media consumption and planting and risk management decisions. Overall, partisan bias exists despite financial interest at stake but does not affect behaviors.

We estimate the impact of an unprecedented surge in ad hoc farm payments on grain inventories held by farmers. Payments thought to be decoupled from production may still distort markets if they affect other outcomes such as inventories. Through the Market Facilitation Program, US farmers received approximately 23 billion dollars over two marketing years. The economic theory of commodity storage suggests such a cash injection can increase inventories by lowering the opportunity cost of storage. Using a panel event study framework, we find Market Facilitation Program payments significantly increased grain storage by US farmers without similar impacts on off-farm inventories.

Poor diet quality has been identified as a primary driver of malnutrition and increasing burden of noncommunicable diseases in low- and middle-income countries. Low fruit and vegetable consumption contributes to poor diet quality. We experimentally assess whether videos embedded messages about increasing fruit and vegetable consumption affect consumption. Four months after viewing either a basic video or a video that explains why fruits and vegetables can improve health and nutrition outcomes, average household consumption of fruits and vegetables increased by about 9% in both treatment groups relative to the control group, both in kilocalorie and consumption expenditure terms.

Family forest landowners own and manage much of the world's forests, but we know little about their willingness to control biological invasions on their properties. Using a choice experiment, we find that landowners prefer mechanical methods and strongly oppose chemical methods when controlling the spread of an invasive shrub. Their choices are heterogeneously affected by ecosystem service outcomes resulting from control, namely timber production, trail recreation, and wildlife viewing. Landowners view their decision to control the invasive species on their land as a complement to the control by neighbors, offering further support for the areawide management of forest invasive species.

This study assesses the economic and water quality impacts of implementing a dairy pricing policy under Federal Milk Marketing Order system designed to alleviate milk prices plummet occurred at the beginning of pandemic. Using a 12-region, positive mathematical programing model of livestock production in the Chesapeake Bay watershed, we find that pricing policy induces significant expansions in dairy sectors, generates higher level of total net revenue in regions having large base-period dairy sectors. For water quality, we find that policy leads to an increase in nitrogen emissions but a decrease in phosphorus emissions for the livestock industry as a whole in most studied regions.
