While existing literature identifies high transaction costs and market imperfections as challenges faced by smallholders in accessing agricultural markets, less attention has been paid to the role of constraints to the production of a marketable surplus. Specifically, there is a dearth of empirical evidence about how liquidity constraints during the production period that limit smallholders’ investments in agricultural inputs can affect agricultural production and subsequently their market participation and choice of marketing channel. We explore this issue in the context of the Zambian maize market during a period when the country's parastatal marketing board – the Food Reserve Agency (FRA) – operated alongside private buyers and purchased large volumes of maize at a pan-territorial price that exceeded average market prices. Although we cannot definitively identify causal effects, we find strong and robust associations indicating that smallholder maize-growing households who were liquidity-constrained during the production period harvested less maize, were less likely to sell maize, and were less likely to sell to the FRA, as compared to those who were unconstrained. Liquidity constraints during the production period likely exacerbate the already disproportionate capture of FRA benefits by wealthier farmers.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"56 1","pages":"73-91"},"PeriodicalIF":4.5,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12863","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117688","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 explores how STRV adoption affects farmer decision-making and productivity in Nepal in a non-drought year. STRVs are bred to be high-yielding and tolerant to climate shocks such as drought. To assess the effect of input measurements on treatment effects, we collected information from 900 households on STRV adoption and input use. We also conducted a survey experiment in which half of sampled households were randomly assigned to answer additional, more detailed questions on agricultural inputs. Farmers apply more total chemical fertilizer, pesticides, early-season chemical fertilizer, and land preparation labor to plots planted with STRVs compared to traditional varieties (TVs). Detailed input data enhances our understanding of how this “crowding-in” effect of STRV adoption on input use compares with other high-yielding varieties. While farmers increase application of a subset of these inputs on other improved variety types such as hybrids, results suggest that crowd-in effects are most consistent for STRVs. In the absence of drought, STRVs also provide a similar yield boost and yield variance reduction over TVs compared to other, non-stress tolerant improved varieties. Results suggest that improved varietal adoption, and STRV adoption in particular, can improve household productivity and modernization of agriculture.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"56 1","pages":"145-160"},"PeriodicalIF":4.5,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/agec.12869","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117689","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}

As an illustration, this study examines the impact of industrial water pollution from manufacturing firms on rice production in Jiangsu, China. By combining data from the China Rural Fixed Point Survey with the China Environmental Statistics Database, we employ an extended translog production function to distinguish between the effects of industrial water pollution and farmers’ adaptation behaviors. Our results demonstrate that industrial chemical oxygen demand (COD) has a direct biological effect on paddy rice growth, reducing rice yields by 3.76 to 4.17 percent. This detrimental effect is most pronounced within a radius of 5 kg from the village center. Additionally, farmers increase their operating inputs to mitigate the adverse effects of industrial water pollution. These findings underscore the need for stringent environmental regulations and enhanced environmental education in rural areas to promote the sustainable development of both manufacturing industry and agriculture in developing countries.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"56 1","pages":"108-123"},"PeriodicalIF":4.5,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143114228","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 study examines the impact of livelihood diversification on farm profits among smallholder rice farmers in the Central Luzon Region (CLR) of the Philippines using long-term farm-level panel data spanning from 1966 to 2016. We employed a random-effects ordered probit model to investigate the drivers of livelihood diversification and then used the mixed Markov chain model to analyze the transition of households from less to more diversified livelihoods and its impact on farm profits over time. Our findings reveal substantial diversification among households over time. In particular, the elevation of the farm location is a key driver of rice farm households’ probability to diversify. The estimates show that an increase in the latitude of the farm location increases the probability of rice farmers in the CLR to diversify. We find that 64% of the rice farm households constitute farmers for whom diversification can be a strategy for survival. For medium- to high-profit farm categories, diversification tends to protect farmers against farm profit losses arising from adverse climatic and weather variability.","PeriodicalId":50837,"journal":{"name":"Agricultural Economics","volume":"55 6","pages":"1040-1056"},"PeriodicalIF":4.5,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664625","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}
