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.</p>","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}

Sectoral participants will react by undertaking a variety of adaptation and mitigation actions. Adaptation is largely inevitable but may require public action to either provide public goods or support private adaptation. Agriculture will also play an important role in mitigating climate change, as in cases it can provide low-cost net greenhouse gas reductions. This paper will discuss the economic and physical characteristics of adaptation and mitigation actions that can be taken in the agricultural sector plus introduce some analysis results and possible directions. Clearly, across these areas, economists will find rich areas for economic inquiry.</p>","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 2","pages":"368-389"},"PeriodicalIF":4.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404830","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}

Our results indicate that a 1% increase in cropland leads to a 0.5% increase in the size of HABs in lakes larger than 20 km<sup>2</sup>. The increase in cropland not only affects the size of HABs but also significantly prolongs their duration on average. Furthermore, we provide evidence of a diminishing legacy effect of cropland on HAB area over time and a nonlinear relationship between cropland area and HABs. Fertilizer leakage from cropland shapes the entire pollution mechanism, with farming practices that require elevated fertilizer posing significantly greater impacts on water quality. While the nationwide fertilizer reduction policy implemented in 2015 successfully dampens HABs in nonreservoir lakes during the initial three years, its long-term effects remain uncertain. This study highlights the potential of satellite imagery data for economic analyses of nutrient pollution in China.</p>","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 3","pages":"958-989"},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826982","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}

Reflective of the broiler industry market structure, in the theoretical part of the article we adopt the model of a Cournot oligopoly with a competitive fringe and then apply merger simulation to predict the welfare effects. We fit our theoretical framework to the pre-merger data under the assumption of different numbers of oligopoly firms. The results suggest that the merger between Sanderson Farms and Wayne Farms will significantly increase the market price of chicken meat and decrease consumer surplus, and that the magnitude of these impacts hinges on the size of the oligopoly. The net welfare effect could be positive or negative, but it is not statistically significant at the 5% level.</p>","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 3","pages":"869-887"},"PeriodicalIF":4.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143826852","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}
