However, the empirical evidence documenting the association between SFSC participation and farm economic performance has been mixed. In this study, through a meta-analysis using a logistic regression, we identify key factors to explain differences between studies that find better economic performance in SFSC and those that do not. Our meta-analysis consists of 48 studies published in English and French from 2000 to 2022 that examine the economic performance of farms engaged in SFSC. Based on far more empirical evidence than previous reviews, we find that the relationship between SFSC participation and farmer income remains ambiguous. More specifically the findings indicate that the reported effect of SFSC on a farm economic performance varies depending on location and the indicator used to capture the economic performance of farms. Studies conducted in Europe are more likely to report higher farmer income as are studies that use profit satisfaction metrics rather than measures of gross or net income. We also emphasize the need to interpret the reported results cautiously because few are based on causal inference methods. Furthermore, the very few studies that account for selection bias often do so with inadequate corrections.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 3","pages":"400-413"},"PeriodicalIF":4.1,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45525768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We focus on how risk and ambiguity aversion affect consumers’ willingness to pay (WTP) to avoid genetically modified (GM) food or GE food and whether the impacts of risk and ambiguity aversion differ between GM and GE food. We collected the data in 2020 through a nationwide online survey in China. The multiple price list method is used to estimate the premiums that consumers are willing to pay for conventional rice to avoid GM/GE rice. Our results show that Chinese urban consumers are more concerned about the health, environmental, and ethical impacts of genetic modification than gene editing technology. They are willing to pay lower premiums when the alternative is GE rice than when it is GM rice. We further find that both risk aversion and ambiguity aversion have significant negative impacts on respondents’ WTP for food derived from gene technologies, with ambiguity aversion being more influential than risk aversion for both GM and GE rice. However, there is no significant difference in how risk aversion and ambiguity aversion affect the respondents’ WTP to avoid GM or GE rice.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 3","pages":"414-428"},"PeriodicalIF":4.1,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46375502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We distinguish between the effects of changes in growing season weather from those due to changes in long-term climate trends and the heterogeneity in these effects across the distribution of crop yields by estimating naïve and climate penalty inclusive models using fixed-effect quantile panel models. We observe an absence of adaptation against rising temperatures for rice and wheat. However, we find a statistically significant presence of adaptation for wheat and maize for changes in precipitation, though the magnitude is small. Moreover, we find that the effects are asymmetric, and are larger at the lower tail of productivity distribution and smaller at the upper tail of the distribution. A 1°C increase in temperature lowers rice and wheat productivity by 23% and 9%, respectively at the first quantile, but the damage is only 6% and 5% at the ninth quantile. Heterogeneity in impacts and adaptation estimates over the yield distribution curve and across crops suggests the importance of customizing strategies for adaptation to changing weather and climate conditions across regions, crops, and current productivity levels.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 2","pages":"147-160"},"PeriodicalIF":4.1,"publicationDate":"2023-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12765","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45751190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The low application is attributed to poor access to fertilizer and an inefficient distribution system. The government of Nepal issued a “Fertilizer Distribution Directive (FDD) 2020” to improve the distribution system. We assessed the impacts of involving the private sector in selling fertilizer to farmers. We examined whether the market transaction cost proxied by farmers’ search cost (communication and travel cost), travel time to visit the stores, and the opportunity cost of time spent in purchasing fertilizer have been reduced by FDD 2020. A difference-in-difference approach refined with propensity score matching was used to estimate the fertilizer distribution efficiency using survey data from 619 households across six districts. Private sector involvement was found to reduce travel time to fertilizer retailers by about 10 min and transaction costs to purchase subsidized fertilizer by about 20 Nepalese Rupees (NPR) per season, compared to the conventional approach of sale by farmer cooperatives. Implementation of the directive has removed the bias of cooperatives selling fertilizer only to members, especially medium and large-scale farmers. The directive and private sector involvement have led to a more equitable and efficient distribution of subsidized fertilizer. However, the government should routinely monitor and regulate the fertilizer mainly targeted to the private fertilizer retailers.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 3","pages":"429-446"},"PeriodicalIF":4.1,"publicationDate":"2023-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42868669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article explores the possibilities of organic agriculture to enhance the bargaining power of farmers along with the role of concentration in downstream industries. Using a dataset with more than 200,000 observations from approximately 40,000 dairy farms, I estimate markups of price over marginal cost in dairy farming as a measure of market power in the EU. The results show that organic farmers achieve a significant markup premium over conventional farmers. With increasing market shares of organic milk in total milk production markups of conventional farmers diminish whereas those of organic farmers are unaffected. Farm-level markups decrease with increasing market shares of medium-sized dairy processors and increase with increasing market shares of large processors. The presence of large multinational retail chains shows an adverse impact on farmers’ markups.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 2","pages":"161-178"},"PeriodicalIF":4.1,"publicationDate":"2023-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12762","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42219361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Economic models of intersectoral labor migration focus on expected return differentials as the primary cause of migration from one sector to another. Empirical applications typically assume that migration occurs as soon as the return differential exceeds Marshallian migration costs, but recent work has focused on embedding the migration decision in a real options framework. Structural and institutional elements can also affect the speed at which the share of agricultural labor declines. We consider the factors influencing intersectoral labor migration in the U.S. and Japan using aggregate migration equations and several definitions of agricultural labor and return differentials. We show that real options, although relevant at the household level, have limited implications for sector-level empirical models. Our estimates are inconclusive regarding the importance of the Marshallian trigger in the migration decision, with heterogeneity across the two countries and labor definitions. We argue that this heterogeneity in the wage and migration relationship is driven by differences in the structures of the agricultural sectors.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 3","pages":"364-381"},"PeriodicalIF":4.1,"publicationDate":"2023-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12761","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44885697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article aims to analyze how drought disturbances affect price differences in local food markets. Special attention is paid to differences in product quality and marketing channels. To study the mechanism behind price differences, our analysis is framed within the food market integration theory. Our methodology follows a dyadic regression approach, which allows us to exploit the panel data structure of our market price data. We use monthly Asterix potato and long shelf-life tomato market prices from traditional markets and supermarkets in Chile. To measure drought intensity, we use remote sensing data to construct a drought index. Results show that drought shocks reduce market price differentials around harvesting and commercialization periods, which is supported by the existence of market integration. We also find that prices of high-quality products, less perishable products, and those taken from traditional markets respond more intensively to droughts and take more time to be transmitted. A direct link between droughts and crop quality, as well as supermarkets’ larger capacity for buffer stock, may be behind these interpretations. Product differentiation and retail price rigidity arguments are also discussed.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 3","pages":"349-363"},"PeriodicalIF":4.1,"publicationDate":"2023-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45184325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stigma is commonly cited as a barrier to use and may arise due to the perceived low product quality of pantry offerings. This study tests the hypothesis that “product stigma” is present among prospective pantry clients. In an online experimental survey of low-income respondents, we ask participants to evaluate food items under four different treatments. In a two-by-two randomized design, in one dimension they are told the food is from a grocery store or from a food pantry, and in the other dimension they are or are not provided with photos of the food items, in some cases indicating a popular brand. The study finds that respondents exhibit a negative perception of the quality of food from a pantry, but that perception is largely offset when they are shown an informative visual depiction of that food. The effect of brand information is explored in a second online experimental survey and found to be an important component of consumer perception, partly mitigating the product stigma effect of food pantry offerings, but less so than a photo does. Results suggest that food banks and food pantries may combat product stigma through marketing that uses photos, brand names, or both to depict the quality of the products they offer. Such interventions may encourage current users to visit more frequently and needy non-users to visit at all.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 2","pages":"327-344"},"PeriodicalIF":4.1,"publicationDate":"2023-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50124923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To deduce evidence or lack of proof of convergence in price series, we also examine convergence using sigma and beta convergence specified in both unconditional and conditional frameworks. The methodology used is driven by the need to address three key concerns: (i) the likelihood of finding stationary price differentials, (ii) the magnitude of these differentials, and (iii) their speed of adjustment. To evaluate these concerns, we use monthly data for 18 price series drawn from these six countries from September 2011 to February 2021. The evidence points to a lack of international convergence. This gives rise to the possibility that a shield from a general downward export price trend is already in place for some exporters. Furthermore, we find that the likelihood of convergence is greater between pairs of price series that are characterized as high quality or having the same country of origin or having similar market share. Evidence also suggests that a converged pairing is more likely to have a smaller price differential if both price series are for low-quality rice.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"54 1","pages":"127-141"},"PeriodicalIF":4.1,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46000934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
