This paper studies how these factors impact worker productivity, which can have implications for worker health, well-being, and income as well as farm payroll, production, and profitability. Our analysis uses 6 years of payroll records of harvesters on two large farms combined with pollution and weather monitor data from multiple sources. We address simultaneity issues by exploring pollution measurements from nearby upwind and downwind monitors and incorporating an alternative PM2.5 measure that better captures ambient or regional concentration. Across all specifications, results suggest that heightened concentrations of ground-level ozone and PM2.5 are associated with reduced productivity. In our main specification, we find that one standard deviation increases in ozone and PM2.5 are associated with reductions in productivity of 2% and 1.1%, respectively.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 4","pages":"1329-1353"},"PeriodicalIF":4.2,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12439","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135819081","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}

Agricultural support programs usually cause significant fiscal burdens on government budgets. These programs can be generally categorized into decoupled and coupled programs, and one longstanding research interest of previous literature is whether these programs are decoupled or coupled with farm production practices. In Taiwan, a unique land direct payment (LDP) program to rice farms was implemented to ease severe financial burden of the price support program with government purchase. In contrast to production control programs imposing quantity restrictions on farm production, this program is voluntary for rice farms, and participants are paid at a fixed rate per hectare of farmland. This paper examines the impacts of this program on farm income and farm production practices in Taiwan. The causal effect of the program is identified based on the exogenous rollout of the policy across multiple times and areas. We construct a dataset linking nationally representative rice farm surveys over several years and administrative records on program recipients to estimate the local average treatment effect of the program. We find that the effect is 4% of farm income. In addition, program participants rely less on price support programs and produce less rice and use less fertilizer, pesticide, and machinery. Although the LDP reduces rice production, we find that it causes overall government spending on the price support and direct payment programs to increase by 8.7% after the LDP.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 4","pages":"1454-1476"},"PeriodicalIF":4.2,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135974708","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}

Many firms in commodity supply chains use storage, but we know little about which firms and why. The economic theory of storage asserts that firms in a competitive market for inventories will store based on current and expected market prices and the per-unit cost of storing. We empirically test at the firm-level the importance of one major cost of storage: the opportunity cost of capital used to value foregone revenue from deferred commodity sales. To do so, we use panel data from thousands of Illinois farms who hold inventories of corn and soybeans. Although interest rates as a measure of capital costs are unlikely to vary widely across firms in this context, we exploit variation in the weighted average cost of capital due to cross-firm differences in capital structure. Using two-way fixed effects regressions, we find a statistically significant average effect of capital costs on inventory that masks notable heterogeneity across firms. Panel quantile regressions reveal two groups of firms: one whose inventory holdings are responsive to changes in the opportunity cost of storage and another whose are not. Our results suggest some farms behave like the profit-maximizing ones from theory but substantial inframarginal commodity inventories are held by farms for other reasons.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 2","pages":"526-546"},"PeriodicalIF":4.2,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12436","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510839","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}

To achieve this objective, we utilize a county-level panel data set with information on cover crop adoption acres, crop insurance losses (i.e., specifically due to drought, excess heat, or excess moisture), and a number of weather variables. The data cover the main row crop production region in the Midwestern United States (US) for the period 2005 to 2018. We utilize linear fixed effects econometric models and a number of robustness checks in the empirical analysis (i.e., a fractional regression approach, two “external-instrument-free” estimation procedures, and a variety of alternative empirical specifications). The estimation methods used take advantage of the panel nature of the data to address various specification and endogeneity issues. We find evidence that counties with higher cover crop adoption tend to have lower crop insurance losses due to drought, excess heat, or excess moisture. Our analysis also indicates that cover crops likely have stronger loss mitigation effects against excess moisture events (like floods) and somewhat weaker loss mitigation impacts against droughts and excess heat. Nonetheless, our results overall suggest that cover crops can enhance resilience to extreme weather events and have the potential to be an effective climate change adaptation strategy in US agriculture.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 4","pages":"1410-1434"},"PeriodicalIF":4.2,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12431","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136014393","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 examine intrahousehold decision-making dynamics that shape smallholder households' decision to use mechanical rice transplanting (MRT), a technology that disproportionately influences demand for women's labor. To study the adoption decision, we experimentally estimate the willingness to pay for MRT services both at the individual and household level. We find that women value MRT more than men, especially when they participate in transplanting on their own farms. This preference heterogeneity is evident in the unconditional differences between women's and men's valuation and differences conditional on their individual observable characteristics. Despite having stronger preferences for MRT, women have less influence on the household's technology adoption decision than men. This differential influence over the MRT adoption decision reflects the intrahousehold power structure: in households where women have less control over assets, they also have less influence over the MRT adoption decision. Our results highlight how technological changes interact with unobserved, gender-based intrahousehold power relations to influence agricultural production decisions and, by extension, the gendered allocation of labor and welfare of women.","PeriodicalId":55537,"journal":{"name":"American Journal of Agricultural Economics","volume":"106 2","pages":"684-711"},"PeriodicalIF":4.2,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ajae.12430","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135738915","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}
