The exposure of agricultural production systems to hurricanes varies between regions in contrast to global risks like commodity price volatility and international trade policies. The regional differences in hurricane exposure may lead to heterogeneity in crop insurance premium rates. This work aims to measure the impact of hurricane incidence on production losses for crops grown in the Mississippi Delta. We leverage a county-month panel of insurance losses spanning 2002–2021 from the US Department of Agriculture Risk Management Agency, and daily data from the National Oceanic and Atmospheric Administration National Hurricane Center, to construct novel measures for hurricane treatment assignment under a difference-in-differences identification strategy. We find hurricane incidence results in economically significant losses that are strikingly heterogeneous across crops. We also demonstrate that measuring hurricane treatment is a critical concern for credible identification as simplistic approaches are associated with attenuation bias relative to our approach which accounts for the dynamic changes in the scope and intensity of a hurricane. We discuss implications of these results for two important policy instruments, traditional crop insurance premium rating and the more recently released Hurricane Insurance Protection—Wind Index product.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"107 5","pages":"1438-1456"},"PeriodicalIF":3.3,"publicationDate":"2025-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145022367","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}

McCluskey","doi":"10.1111/ajae.12556","DOIUrl":"https://doi.org/10.1111/ajae.12556","url":null,"abstract":"This study examines the effects of new food store openings on customer traffic to incumbent stores using a modified difference-in-differences approach and cellphone location data from the contiguous United States in 2019. Analysis of both the intensive margin (total visit counts) and the extensive margin (unique visitors) reveals substantial spatial, temporal, and demographic heterogeneity, highlighting that ignoring these variations may lead to misleading conclusions about customer behavior. Grocery store openings, for example, reduce visits to food-at-home incumbents in close proximity but affect food-away-from-home incumbents over broader distances. The magnitude of these effects varies with demographics. Entrant stores offering fresh food options, such as grocery stores, reduce traffic to outlets that sell more processed foods—such as fast-food and convenience stores. However, the reductions remain modest—generally below 5% of monthly visits—and are statistically significant for White and high-income visitors when disaggregated by demographics. Complementarity effects emerge when entrants and incumbents are not direct competitors, particularly within a one-mile range. For instance, grocery entry does not reduce traffic to fast-food stores nearby but does so at greater distances. Conversely, competition within similar store formats intensifies business-stealing effects, such as dollar store openings reducing traffic to other smaller store formats while leaving grocery stores unaffected. These findings underscore the competitive dynamics shaping the U.S. food environment.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 2","pages":"686-705"},"PeriodicalIF":3.3,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12556","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146176271","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}

Recent literature has shown evidence of wage gaps in academia based on gender and race; however, little is known about whether a wage gap might exist for foreign-born faculty. This paper studies the compensation gap between US- and foreign-born agricultural and life science faculty at 52 US land-grant universities (LGU) using a survey of over 1400 scientists conducted in 2005 and 2015. We develop a framework to categorize the sources of a potential compensation gap into testable categories that capture direct discrimination as well as indirect (systemic) discrimination. We find wage differences in total annual compensation among the foreign-born and the US-born, tenure-track faculty, however, the gap in the base annual salary is insignificant. This suggests that additional salary components like grants and summer teachings may not be equally available to foreign-born faculty even though, on average, foreign-born scientists work are more productive than US-born scientists on most common output metrics. The decomposition analysis suggests that about one-half of the gap (at 10% level) in the base salary and 60% of the differences in total salary (at 5% level)is due to various types of direct or systemic discrimination. Using our framework, we then rule in and rule out some important types of systemic discrimination.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 2","pages":"706-736"},"PeriodicalIF":3.3,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12558","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146193476","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}

Adverse Effect Wage Rates (AEWRs) are regional minimum wages paid to foreign farmworkers working in the United States under the H-2A temporary agricultural guest worker program. Recent increases in AEWRs have prompted discussions over the methodology and data sources used to compute them, including debates about whether AEWRs should be frozen or capped in the future. Employer and farmworker groups hold opposing views on the desirability and implications of changes to AEWRs. In this paper, we develop a simple theoretical framework that suggests higher AEWRs may induce spillover effects that lead to higher wages for non-H-2A farmworkers. Using confidential wage data from the National Agricultural Workers Survey, we test the labor market spillover hypothesis by comparing changes in non-H-2A farmworker wages and AEWRs across U.S. regions between 1996 and 2022. Our estimates suggest that a 10% increase in the AEWR causes, at most, a 2.8% increase in the wages of non-H-2A farmworkers across the United States. We find that freezing the AEWR for 1 year would reduce the growth of wages paid to non-H-2A farmworkers by as much as $475 million. Our analysis suggests that the recent policy proposals could lower labor costs for U.S. farm employers but limit wage growth for non-H-2A farmworkers.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 2","pages":"494-517"},"PeriodicalIF":3.3,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12557","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146176228","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}

As the United States continues to invest in this vital infrastructure, we provide the first empirical examination of the impact of broadband internet speed upgrades on farm-level sale prices and county-level cash rents in 12 Midwestern US states from 2016 to 2021. We employ a Bartik shift-share instrument with broadband technology shares to address the potential endogeneity in the deployment and upgrades of broadband internet. Our results indicate that a one megabit per second (Mbps) increase in download speed raises farmland sale prices by 0.268% and county-level cash rents by 0.070%. Additionally, a one-percentage-point increase in the download speed growth rate leads to a 0.041 percentage point increase in the growth rate of county-level cash rents. By decomposing the Bartik shift-share instrument, we demonstrate that the exogeneity of the initial market share of satellite technology contributes most to identification. Our research provides valuable insights for policymaking by quantifying the return on broadband investment and identifying areas and types of farms that benefit more from higher internet speed.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"108 2","pages":"566-598"},"PeriodicalIF":3.3,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146193658","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}
