The improved bag had two inner layers of high-density plastic that created an airtight seal around the grain stored in it. The seal killed insects through suffocation rather than insecticide. The bag also had a branded label from its manufacturer on its outer layer to help distinguish it from a generic single-layer, woven storage bag. We estimated the size of the price differential (premium) that the average consumer placed on unobservable grain quality, as measured through the WTP premium for grain sold in the improved bag with a label. We also estimated the effect that consumers’ previous awareness of the improved bag had on their valuation of observable and unobservable quality. Our results indicated that on average consumers in Niger were willing to pay a 10% premium for cowpea stored and sold in the improved storage bag compared to cowpea of the same observable quality that was sold in a generic woven bag. The same unobservable quality premium was 17% in Nigeria. The results from this study provide evidence that there may be a latent demand for quality proxied by food safety among limited resource people in sub-Saharan Africa and that improved products with branded labels can potentially provide a quality signal to the market.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"130 ","pages":"Article 102774"},"PeriodicalIF":6.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In high-income countries, rising food prices have been accompanied by record corporate profits, sparking allegations of “greedflation”. Policymakers around the world are investigating ways to curb rising food prices and build more sustainable food systems. Strikingly missing from this policy conversation is the role of diverse, local alternatives, like farmers’ markets in supporting more resilient food systems. This study investigates the inflationary dynamics within Canada’s local food systems compared to mainstream grocery retail. Employing a mixed methods approach, the research team analyzed price data from 223 farmers’ market vendors across Canada from 2018 to 2023 and conducted 17 semi-structured interviews with vendors. The exploratory findings reveal that most local food products experienced less inflation than those in mainstream grocery stores. The results underscore the need for policy frameworks that support local food systems to enhance food security and sustainability. The study contributes to the broader discourse on food price inflation and corporate concentration, offering insights that are relevant beyond the Canadian policy context.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"130 ","pages":"Article 102773"},"PeriodicalIF":6.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143094602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on data from parliamentary speeches between January 2017 and June 2022, the research aims to understand whether and, if so, how key challenges of the agri-food sector identified by scientists are addressed by the parliamentarians. The paper thus adds empirical evidence concerning the debate on the uptake of research knowledge in politics. It does so by identifying key topics, tracking their temporal evolution, and assessing how party affiliation, constituency, gender, and age of the speakers influence discourse. The results reveal 24 distinct topics, spanning areas such as agriculture-environment interactions, rural development, animal welfare, and economic aspects of farming. Temporal analysis shows shifting priorities over time, with economic issues and sector transformation gaining prominence as CAP negotiations progress. Critically, the findings suggest that parliamentary discourse in Germany aligns with main challenges the agri-food sector faces, albeit with variations influenced by party affiliation, geographical and demographic factors. Overall, this study contributes to a better understanding of parliamentary engagement with agricultural issues and informs policy-making and voter decision-making processes.

Using a participatory approach, we co-design a choice-architecture intervention to assess whether inverting the sequence of Mediterranean lunch dishes served in school canteens is effective in reducing food waste. We implement a randomized control trial using 26 Italian schools, creating one of the largest and the most diverse samples achieved so far for such an experiment. Hence, our analysis yields evidence of internal and external validity far beyond existing interventions which consider only a few education institutions without random selection. A food mass flow analysis of the weighed prepared food, serving waste and plate waste per meal course suggests that in primary school canteens 29% of the lunch prepared gets wasted, i.e., 22,000 tons per year in Italy. Big catering providers are found to produce 23% more food waste. Prioritizing the vegetable side dish as first course has heterogeneous effects across school clusters changing the share of plate waste in total vegetable servings between −26 pp to + 32 pp. Also, the side dish plate waste depends on the type of vegetables served. Differences in lunch implementation and food and eating environments across schools appear to dominate the effectiveness of the intervention, hence, no treatment effect is found for the full sample. Upscaling of the dish reordering as a binding policy strategy for the entire regional territory is therefore not recommended.

Our focus is on representative studies along this value chain in low and middle income countries where micronutrient malnutrition is most prevalent. The papers reviewed suggest that (a) both production diversity and market access work hand-in-hand to improve dietary quality.

Furthermore, the poor are most sensitive to changes in the relative prices of micronutrient-rich foods.

The TFP algorithm was driven primarily by the cost and food group constraints rather than the objective function. The constraints with the highest Lagrangian semi-elasticities were, in order: the cost constraint, a food energy constraint, a vitamin E constraint, and particular food group constraints such as dairy. The implications for recommended SNAP benefit amounts depend on which constraints are used and on how much difference between the model diet and current consumption is considered acceptable.

Although simple post-harvest mitigation measures exist, their adoption by Haitian farmers remains limited. This study assesses the willingness to accept (WTA) of peanut producers in Haiti to implement post-harvest measures, using a reversed Becker-DeGroot-Marschak (BDM) auction. It also tests the effect on WTA of a conditional market access. For one group the research project commits to purchase peanuts at a predetermined price if aflatoxin levels meet a maximum of 10 parts per billion, while another group receives unconditional market access at the same predetermined price. Moreover, Haitian supermarket consumers’ willingness to pay (WTP) a premium for a local peanut butter (mamba) certified to meet aflatoxin standards is explored. Results indicate that conditional market access generates higher WTA. Haitian supermarket consumers show strong interest in certified peanut butter, with a declared premium of 21.1 % over the market price of a 16-ounce jar of non-certified peanut butter. If we consider intermediary margins as high as 86 % of the final consumer price—well above the current 68 % reported in previous studies—as well as for a potential hypothetical bias as high as two thirds of the stated WTP, this premium is sufficient to incentivize Haitian peanut producers, measured by their observed WTA.
