This article investigates whether a more uncertain world will strengthen the case for conservation investments strategies that diversify risk. We consider two ways the world could be more uncertain: (1) a more uncertain future climate that increases uncertainty in conservation benefits and (2) broader market uncertainties affecting conservation costs. We use concepts from expected utility theory to highlight that, as there is more risk to diversify, the incentive and ability to diversify risk depend on relative changes in expected payoffs at each site and covariances across sites as uncertainty increases. We then illustrate our findings using an application to land protection investments in southern Appalachia. In this biodiversity hotspot, we find risk diversification is most cost-effective when conservation agencies face multiple uncertainties, and market uncertainty creates greater incentives to diversify risk than climate uncertainty.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"77-105"},"PeriodicalIF":3.3,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706309","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}

Understanding how stable and predictable these welfare estimates are over time is important for applying them in policy. Yet, revealed preference models of recreation demand have received few temporal stability assessments compared to other nonmarket valuation methods. We use a large administrative panel dataset on campground reservations covering 10 years to study temporal stability and predictability of environmental quality welfare estimates. Welfare estimates are statistically different across years in 62% of the comparisons, and this ranges from 47%–71% depending on modeling assumptions. Using an event study design, we find evidence that week-specific welfare estimates are stable after an initial adjustment week in response to a change in environmental quality. Our findings further reveal that using 2 years of data in the modeling compared to a single year improves the prediction of future welfare measure estimates substantially, but further prediction improvements are modest when including more than 2 years of data. Predictions of welfare estimates are more consistent when using data closer in time to the prediction year. We discuss the implications of our results for using revealed preference studies in policy analysis.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 3","pages":"846-868"},"PeriodicalIF":4.2,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826826","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}

Ward","doi":"10.1111/ajae.12513","DOIUrl":"https://doi.org/10.1111/ajae.12513","url":null,"abstract":"Informational barriers are often considered to be a major constraint to the adoption of improved farming practices, inputs, and technologies by smallholder farmers. In the Indian context, it is widely believed that farmers misapply chemical fertilizers because they lack scientific information on soil conditions and corresponding fertilizer recommendations, thus resulting in imbalanced and potentially detrimental fertilizer application. Policymakers are frequently interested in providing farmers with various streams of information to overcome these informational barriers to optimize farming activities. However, such informational interventions frequently fail either because generic recommendations may be ill-suited for decision makers in highly heterogeneous agricultural environments or because farmers' beliefs may be so entrenched as to make them unresponsive to new information. We implemented a field experiment in Bihar, India to test whether plot-specific fertilizer recommendations affect farmers' fertilizer use. We find little evidence for sizable impacts on fertilizer use in general, though impacts are more apparent for low cost or costless recommendations such as increasing the use of highly subsidized fertilizers or shifting the timing of application. Despite modest evidence of such effects, even those fall short of their potential magnitude. We show that treated farmers who are less confident in their subjective beliefs about optimal fertilizer application rates (i.e., with more disperse priors) are more responsive to the recommendations and have a higher ex ante willingness to pay for soil testing. These results suggest that heterogeneity in beliefs may constrain the overall effectiveness of information provision, even when the information is tailored to individual farms.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 5","pages":"1406-1437"},"PeriodicalIF":3.3,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12513","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022337","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}

Richards, Bradley Rickard","doi":"10.1111/ajae.12516","DOIUrl":"https://doi.org/10.1111/ajae.12516","url":null,"abstract":"Consumers tend to choose the type of store, or grocery channel, on the basis of “destination categories,” or categories that tend to be important attractors relative to others. Whether or not a category is truly important to generating incremental market share, however, is a difficult empirical question, because there has been little exogenous variation that permits a clear test of whether categories tend to attract traffic. In this study, we leverage a change in beer distribution laws in the state of Colorado that permitted full-strength beer to be sold for the first time in traditional supermarkets. We use a difference-in-difference estimation strategy to test whether the introduction of a new category of products represented an incremental gain in channel attraction using both consumer panel and retail scanner data. Our results show that the introduction of beer into grocery stores in Colorado led to an increase in total weekly sales (1.2%) and a relative increase in expenditures for some categories, notably those that are likely to be complementary to beer purchases. Additional results using the consumer panel indicate an increase in the frequency of grocery store visits by beer-purchasing households as well as an increase in monthly grocery store expenditures (8.0%) among beer-purchasing households.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 1","pages":"143-175"},"PeriodicalIF":3.3,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12516","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145706636","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}
