Numerous existing groundwater conservation programs provide financial incentives to agricultural producers to permanently retire their groundwater use rights, ceasing irrigation from the associated well. This research estimates the net social benefits of a retirement policy and compares them to net benefits realized under a policy that provides subsidies for incremental reductions in groundwater use. Policies aimed at incremental groundwater use reductions have historically been ignored due, in part, to technological limitations for monitoring water use. Technological advancements make policies based on incremental changes in behavior feasible. We develop a theoretical model to compare water use behavior and welfare under the alternative policies. Then, we use a novel integrated assessment model to empirically illustrate the dynamic economic tradeoffs of the policies for a study area in Kansas. Our analysis shows that resource rents actually decrease under the retirement program relative to a baseline with no conservation policy. Further, subsidizing incremental reductions in groundwater use can dramatically increase the net social benefits of groundwater conservation relative to the retirement policy, but the choice of the subsidy policy parameters plays a critical role in determining its impact and cost to policymakers.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1437-1465"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This issue reflects a dilemma between accommodating consumer convenience, promoting wine industry growth, and generating tax revenue, versus concerns about potential harm to liquor stores. However, there is a lack of empirical studies evaluating the dual impacts of wine sales liberalization following policy reforms. This study uses synthetic control methods and synthetic difference-in-differences to provide robust evidence on the impact that wine sale liberalization has on liquor store closures, employment outcomes, and wine excise tax revenue. Drawing on proprietary NielsenIQ data and official government statistics, the study provides a multidimensional assessment of how a 2016 Tennessee policy reform affected wine sales and supply chain dynamics. The results suggest that allowing grocery stores to sell wine had a statistically insignificant impact on the number of liquor stores, while also increasing wine excise tax revenue. However, there is mixed evidence of a potential short-term decline in liquor store employment, where the statistical significance of the point estimate depends on the statistical approach. Recognizing that policy reform can have unintended economic consequences, these results provide valuable, policy-relevant insights for stakeholders navigating the evolving landscape of alcohol distribution.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1255-1281"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper assesses the effectiveness of a second-best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon. I develop a simulation model that includes on-farm acreage responses and employs a novel field-level dataset from the Saskatchewan Crop Insurance Corporation to measure changes in soil organic carbon stocks attributable to changes in cropping choices. I find that a policy offering optimal subsidies specific to each soil zone for additional hectares of canola, implemented in 2019 and continuing indefinitely for all insured fields in Saskatchewan, generates an external social benefit worth 14.7 billion Canadian dollars when the subsidy is set to maximize the net external social benefit, and 29.4 billion Canadian dollars when it is set to maximize the change in total welfare. This paper highlights the potential environmental and social benefits of second-best policies as a cost-effective alternative to traditional first-best policies. It also shows how economic and biophysical models can be combined to estimate soil characteristics, thereby avoiding the high cost of direct measurement.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1402-1436"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.70020","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both seasonality and growth are important to understand and model to support efficient management. The generalized Gordon–Schaefer model for microdata has been promoted with implications for policy and considers the effects of gear and fishing area on productivity. We extend this model with seasonal adjustments and alternative growth specifications. Using trip-level landing data and satellite tracking of vessels, we apply this model to the Norwegian cod fishery. The model is estimated in two stages: In the first stage, we estimate a production function with season-, area-, gear-, and time-fixed effects. From this stage, we extract an estimate of stock abundance. In the second stage, we use stock as the dependent variable and estimate several stock growth equations. The estimated stock abundance and maximum sustainable yield, an important policy benchmark, compare well with established stock assessments and related harvest advice. However, growth specifications have substantial impacts on policy implications.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1466-1484"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910022","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

If this discrepancy derives from systematic biases in survey data responses on rental market participation, then the existing body of survey-based empirical work on land rental markets impacts may be fundamentally flawed. To examine this issue, we implemented two survey experiments. First, we tested the hypothesis that some categories of rented land are underreported because enumerators and respondents focus primarily on parcels directly managed or cultivated by the household. A random subset of respondents received a priming nudge reminding them to account for all land, including rented- or sharecropped-in and rented- or sharecropped-out parcels. Second, we tested whether households underreport rented- or sharecropped-out land due to reluctance to disclose activities that may carry social or institutional repercussions, using a double-list experiment to infer true rates of participation. Interestingly, our results indicate a significant underreporting of both renting-in and renting-out land but arising through different mechanisms. The priming nudge increased reports of renting-/sharecropping-in by 4 percentage points (equivalent to 13% of landlords in the sample) but had negligible effects on reported renting-/sharecropping-out. By contrast, the list experiment suggests that the true share of renting-out households is about 15%: much higher than the 3% in parcel-roster responses. These results underscore the need for improved survey methods to accurately observe land rental market participation and evaluate its impact.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1376-1401"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.70022","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We study the adoption of TPC by traders in smallholder-based agricultural value chains in low-income countries, where traders aggregate products from many small-scale producers before selling in bulk to downstream processors. In this context, the introduction of TPC services has oftentimes failed. We develop a theoretical model identifying how different market conditions affect traders' choice to purchase certified output from farmers. Next, using a novel lab-in-the-field experiment with Ethiopian wheat traders, we examine the model's predictions. Traders’ willingness to specialize in certified output increases with the share of certified wheat in the market, and this effect is stronger in larger markets. However, we find that traders do not optimally respond to variation in the quality of uncertified wheat in the market. We also analyze conditions where traders deviate from optimal behavior and discuss implications for research and policy making to promote TPC in smallholder-based value-chains.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 5","pages":"1349-1375"},"PeriodicalIF":4.9,"publicationDate":"2026-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.70015","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148909930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
