This paper assesses <em>ex-ante</em> the impact of the reform on nutrient availability and household spending across income groups. Price elasticities are estimated using pooled National Household Income and Expenditure Survey data and a two-step censored quadratic almost ideal demand system model accounting for price and total expenditure endogeneity. Nutritional information is derived from food composition tables. Food items are grouped by processing level as a proxy to explore differences in own- and cross-price effects between ‘healthier’ and ‘less healthy’ items. The demand for ultra-processed sweet and savoury foods is price-inelastic (−0.74 and −0.81, respectively). Lower-income households’ demand is more price-sensitive. The reform applies a reduced rate to a significant number of ultra-processed savoury food items and is associated with an increase in household purchases of calories (0.7%), sugar (0.4%), and saturated fat (1.2%). A counterfactual scenario with a basic tax basket defined based on the Pan American Health Organization nutrient profile model criteria is associated with the largest reductions in calories (−0.2%), sodium (−1.0%), and saturated fat (−0.6%), with higher benefits for lower-income households. It results in minor decreases in household spending (−0.2%). While an increasing number of countries contemplate the taxation of foods high in fat, salt, or sugar, Costa Rica is unique in mandating the consideration of nutritional aspects in determining value-added tax rates. However, the recently adopted basic tax basket may not fulfil this potential.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102824"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474563","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}

Diseases, such as obesity, cardiovascular disease, and diabetes, resulting from these poor dietary choices place a significant burden on public health systems. Measuring nutritional insecurity is difficult to achieve at scale and so the ability to study the relationship between nutritional outcomes and deprivation at a national level is very challenging. This makes it difficult to understand the effect of new policies or track changes over time. To address this challenge, we develop a machine learning approach using massive anonymised transactional data (4 million members and 2.5 billion transactions) in partnership with the retailer The Co-operative Group UK. We engineer a series of variables related to obesogenic diets, including a new measure called ‘Calorie-oriented purchasing’. These variables help illustrate how large-scale transactional data can discriminate between neighbourhoods most affected by deprivation and childhood obesity. Through comparative assessment of machine learning approaches, we find better performance from tree-based models (Random Forest, XGBoost) with the best-achieving accuracy of 0.88 for predicting deprivation and an accuracy of 0.79 for childhood obesity. Calorie-oriented purchasing emerges as a robust predictor of deprivation and childhood obesity at the census area level. Results show this approach can help summarise nutritional insecurity, and support its spatio-temporal monitoring. We conclude with policy implications and recommend retailers adopt new measures for measuring national nutrition insecurity.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"131 ","pages":"Article 102826"},"PeriodicalIF":6.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143510807","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}

However, concerns are mounting about the low and decreasing yield response and profitability of inorganic fertilizer use, particularly in Sub-Saharan Africa. This study aims to refine yield response and profitability models by incorporating recent data from nationally representative and panel datasets spanning six countries. Most countries exhibited low nitrogen yield responsiveness (4–7 kg), while Ghana and Uganda showed higher responsiveness (15–20 kg) per additional 1 kg of nitrogen. Analysis of fertilizer-to-maize price ratios from 2010 to 2023 showed a downward trend, with spikes in 2022 in Ghana, Malawi, Nigeria, and Tanzania. Overall, except for those years, the data suggest a trend of increasingly favorable price incentives for fertilizer use. Ethiopia, Tanzania, and Uganda experienced declines in the fertilizer-to-maize price ratio. Increasing inorganic fertilizer use would be profitable in Ethiopia, Ghana, Nigeria, and Uganda at current market prices, but not in Malawi or Tanzania. Subsidies in Malawi and Tanzania have boosted profitability, but these may not be necessary in Ghana, Nigeria, or Uganda, which already have favorable price incentives; Malawi could benefit by substantially reducing its 80 percent subsidy while maintaining decent price incentives and farm profits.

This paper uses survey data covering 688 households and 1600 plots from Northern and Central Malawi, combined with historical climate data, to assess the extent to which farmers are utilizing CSBs as a seed source and the association of farmer participation in CSBs with a range of other foods system variables. We find that CSBs are the source of about 1/3 of the seeds of maize, groundnut, and soyabean used by the participants and that they source less of their seeds from their own harvest compared to non-participants. While the use of CSB seeds of different crops shows mixed associations with yields at the plot-level, we find that CSB participation is positively associated with higher household food security overall. Furthermore, we find a positive association between exposure to high mean temperatures and rainfall shortages and the propensity to participate in CSBs, suggesting CSBs play a role in adaptation. This study thus shows that CSB participation is associated with several positive food system outcomes, but more research is needed to understand the causal links as well as the efficiency of CSBs compared to other approaches to strengthen farmers’ seed security.</div></div>","PeriodicalId":321,"journal":{"name":"Food Policy","volume":"133 ","pages":"Article 102792"},"PeriodicalIF":6.8,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143099419","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}

Based on the data from the online survey and laboratory experiments, this study conducts a discrete choice experiment (DCE) to evaluate consumers’ willingness to pay (WTPs) for SSBs and examine to what extent nutritional cognition could affect their preferences. More importantly, we extend our analysis by incorporating consumers’ visual attention data based on eye-tracking technology into DCE to highlight the underlying physiological mechanisms of consumers’ choices. The results show that consumers exhibit various preferences and WTPs for different attributes of SSBs, including sugar content, functional category, and health claims. Consumers have higher preferences and WTPs for low-sugar and sugar-free beverages compared to SSBs, especially those with higher nutritional cognition who are more likely to choose sugar-free beverages. Evidence from eye-tracking technology suggests that consumers paying higher visual attention to the specific attribute considered are more likely to choose the products with that attribute, and individuals who exhibit higher nutritional cognition are more attentive to low-sugar and sugar-free attributes.
