We present the first systematic review of the literature on farmer time preference measurements across Europe and North America. We synthesize methodological developments, summarize the empirical findings, and discuss challenges and potential areas for further research. The average reported discount rate of the farmers in Europe and North America is 23% per annum. Farmer time preferences are, however, highly heterogeneous within and across studies. Moreover, we identify methodological challenges and knowledge gaps to be addressed in future research. We draw conclusions for policymakers and researchers.

We examine the effects of the federal crop insurance program on crop production under extreme heat using farm-level data from Kansas. We find that insured dryland corn is 38% more sensitive to extreme heat than uninsured dryland corn. Results also suggest that a uniform C warming scenario leads to yield reductions of 16.7% (11.8%) for insured (uninsured) corn production; and 6.0% (4.4%) for insured (uninsured) wheat production. Warming had a stronger impact with reduced rainfall, especially on insured farms compared with uninsured farms, while altered growing seasons showed potential benefits for wheat but limited improvements for corn.

This study aims to investigate consumer acceptance of gene-edited orange juice, focusing on the influence of behavioral traits. Specifically, we conducted an online survey of US orange juice consumers, using a choice experiment to elicit consumers' preferences for gene editing (GE) versus gene modification (GM) in orange juice. We find that consumers require a significantly larger discount for GM than for GE, and this preference for GE is influenced by multiple behavioral traits. We used a latent cla4ss approach to further analyze choice behavior among consumer segments. Findings indicate significant heterogeneity in preferences across consumer segments, which can be explained by behavioral traits and individual-specific characteristics.

Landowners who value the nonpecuniary benefits of novel cropping systems may be more likely to adopt those systems in response to new market opportunities. We examine ex ante adoption decisions for bioenergy crops in Wisconsin using stated preference data from nonoperator landowners. Bioenergy crops produce biomass, a private good, and may jointly contribute to civic or environmental public goods. We find that pecuniary and nonpecuniary benefits influence landowner decisions, but the effects differ by annual and perennial crop types. Landowners may trade pecuniary for nonpecuniary benefits when equating the marginal utility of land uses, resulting in lower willingness-to-accept values for adoption.

Agriculture remains a leading source of water pollution in the United States, and climate change may exacerbate this relationship. We quantify increases in nutrient runoff following extreme precipitation events, showing that spikes are higher in regions with crop and livestock production. The spike per head is smaller around large-scale livestock production, relative to small-scale, and cover crops mitigate runoff. Legacy nutrients enter the surface water following extreme precipitation, regardless of current activity. We shed light on practices to protect water quality with more frequent extreme precipitation events and demonstrate the importance of including these events in empirical models of water quality.

In smart farming, agricultural technology providers (ATPs) wield market power in both the upstream (data collection/aggregation) and downstream (crop production) markets. Using a two-stage Muth model, this study assesses benefit distribution from ATPs' data-driven services in smart farming. Results show limited farmer returns from data sharing, questioning policymakers' data value focus. While data-driven services offer notable benefits, ATPs capture a significant share due to market power. Addressing ATP market power promotes equitable rent distribution, but perfect competition risks ATPs' sustainability and R&D incentives, presenting a policy challenge for smart farming outcomes.

Many foods cooked at high temperatures produce acrylamide, a probable carcinogen, and neurotoxin. We evaluate how consumers' purchase intentions for potato products and subjective knowledge about conventional foods, genetically engineered (G.E.) foods, and acrylamide respond to information treatments. Information and prior purchases positively influence intentions to purchase potatoes but negatively influence purchase intentions for potato chips and French fries. Value-of-information calculations suggest industry-focused and private-company perspectives are worth $0.01-$0.02/person per month. Our results have practical implications for food system actors seeking to better understand the broader determinants of consumer acceptance behaviors as they relate to G.E. foods that reduce health concerns.

This study analyzes undergraduate students' enrollment intentions and preferences for alternate teaching modalities during the pandemic under a range of reopening scenarios and flexible teaching modalities to investigate the value of flexible learning options and campus life offerings for students. Using primary survey data from six land-grant universities, our findings suggest that there is no one-size-fits-all policy for tackling significant shocks like the pandemic. Business-as-usual was the most divisive, with wide differences in preferences both within and across universities. These results have important implications for future responses to major disruptions in higher education.

Consumption of sustainably produced food enables consumers to contribute to greenhouse gas emission reduction. Using choice experiment data, this study analyzes the effect of socio-demographics and behavioral factors on consumers' willingness to pay (WTP) for sustainably produced beefsteak. Results show increased WTP for traceable beefsteak raised carbon-friendly and humanely. Behavioral factors, such as, lifestyle is affecting this WTP more than socio-demographics and psychographic characteristics. Findings highlight the importance of labeling standards and policies in promoting green consumer behavior targeting lifestyle characteristics.

This study examines the effect of Utah's Greenbelt program, the state's preferential tax-assessment effort to protect farmland, using an instrumental variable-fixed effects strategy. We find that an unintended effect of the program leads to more conversion of agricultural land to development than the protection it provides. The protection effect is concentrated on parcels with smaller agricultural areas, while conversion occurs on parcels with larger agricultural areas. Our findings shed light on the rationale of a proposed amendment to the policy—Utah House Bill 25—which did not pass during the 2016 legislative session.
