Client choice food pantries allow individuals, many of whom are food insecure, to select a preferred bundle of food. To date, interventions to improve the nutrition of food choices in pantries have not included price incentive programs like those employed in the retail food sector because pantries do not charge for food. However, economic incentives may still play a role in food pantry choices through choice architecture. We examined a natural experiment involving two client-choice regimes that effectively altered the opportunity cost of food selections. Longitudinal individual fixed effects models provide evidence that pantry clients responded to changed opportunity costs by selecting more foods that became relatively less expensive and fewer foods that became relatively more costly. Our study highlights the impact of choice architecture, and in particular relative trade-offs, on food selections in the food pantry context.

The transmission of commodities prices from international to local markets is an interesting and deeply investigated topic. A fast and strong link between the two levels of the market is seen by economists as a sign of local market efficiency, allowing actors to respond fast to signals coming from the international market. However, empirical evidence on the topic is mixed, ranging from a very weak linkage between prices in the two markets to a high-speed and almost complete transmission. The present paper aims to advance the knowledge on the topic by focusing on the price transmission of four main cereals – maize, rice, sorghum, and wheat – in 23 developing and fragile economies. Employing a recent World Bank dataset with prices for several local markets in select countries, we estimate panel vector autoregressions (PVAR) to analyze the pass-through effects of international price shocks on local food prices. We find evidence for a relatively strong price transmission elasticity for all commodities except sorghum. Furthermore, the observed transmission of shocks is almost immediate. We present the policy implications of these findings.

With the rising interest in urban agriculture (UA), community gardens have emerged as a common instrument in UA policies aimed at addressing issues related to food security, environmental sustainability, and equality in urban development. As an impure public good, they deliver both private benefits, such as fresh produce, and public benefits, including ecosystem services. However, there has been limited research estimating the value of various features of community gardens. Consequently, assessing the benefit–cost ratio of community garden development policies is a challenging task. Furthermore, many existing community gardens might have been established without a comprehensive understanding of public preferences. To address this gap, we adopt a discrete choice experiment to quantify residents’ willingness to contribute money and time to community gardens in Los Angeles County, California. Our findings indicate that while residents highly value the gardens’ private benefits, they are not inclined to contribute to their public benefits. Additionally, residents’ preferences for community gardens differ based on their socioeconomic status and level of accumulated gardening experience.

Agricultural policy goals should be legitimised by the population, as agriculture is an important recipient of governmental support in Europe. Questions arise as to how people assess these policy goals, which factors affect the perception of agricultural policy goals and to what extent cultural differences influence this assessment. We address these questions by conducting an online survey among 1,542 respondents in the German-, French- and Italian-speaking parts of Switzerland. We find that the multifunctional role of agriculture is strongly anchored in the population’s perception of agricultural policy. The stated preferences of the participants show that increasing animal welfare is clearly the most important agricultural policy goal for Swiss citizens. Controlling for a range of sociodemographic characteristics and personal attitudes, we find evidence of differences between language regions and thus of cultural differences in the assessment of individual agricultural policy goals. For example, compared to respondents in the other two language regions, German-speaking respondents found increasing domestic food production significantly more important, whereas reducing food prices for consumers, increasing farmers’ income, and reducing greenhouse gas emissions were perceived as significantly less important goals. Environmental attitudes were closely related to the perceived importance of agricultural policy goals; thus, we can expect heated discussions in the future, especially if environmental objectives continue to be missed.

From the early 1990s, Mozambique experienced sustained economic growth and both consumption and multidimensional poverty reduced until 2014/15. Starting in the second half of 2015, a deep economic crisis hit. Economic growth plummeted and the national currency devalued significantly, leading to a general increase in prices, especially food prices. Since food products account for more than half of the consumption of poor families, and a high percentage of households are net food buyers, we argue that the food price rise is likely a major factor behind the significant upsurge in the poverty rate observed in 2019/20. Using various analytical approaches and robustness checks, we analyse and link the price trends and the shocks experienced between 2014/15 and 2019/20, in an attempt to examine and uncover how they influenced poverty. While being clearly relevant for policy makers and development partners in Mozambique, who may not have fully appraised the consequences of recent shocks on household welfare, our study is relevant to other developing countries. This is especially so for those that depend on imported food, and characterised by a high percentage of net food buyer households, who spend a large part of their income on food, and experiencing contemporary shocks involving price surges, regional disparities and weak governance. This seems even more important now after the surge in global inflation that followed the invasion of Ukraine in 2022.

To make a difference in lower-income countries, agricultural innovations must be adopted and ultimately diffused across diverse local environments. This study contributes to the ongoing debate about the factors limiting the spread of agricultural innovations by considering the role of heterogenous supply in determining observed demand for the Index-Based Livestock Insurance (IBLI) product, which is a commercial insurance product serving historically uninsured pastoralists in the Horn of Africa. Analysis of sales data from 2010 to 2020 in Ethiopia and Kenya shows that local conditions can reduce the likelihood of supply channels reaching prospective clients, effectively excluding them from accessing insurance, while other factors can work towards increasing supply of insurance while also decreasing demand for it. Surveys collected from insurance sales agents reveals considerable heterogeneity in their ability to and effort in suppling IBLI. Discussions with IBLI’s providers confirms the role of supply constraints in observed demand; the firms consistently point towards the cost of last-mile extension and sales as their largest challenge to increasing sales, and emphasize that it is cost-prohibitive to provide equal access to well-trained insurance agents across the areas that they operate. These findings suggest that current investments aimed at increasing insurance coverage by increasing demand, for example through improved product design or by subsidizing premiums, should be accompanied by investments in developing more cost-effective marketing and distribution processes so that demand can be acted upon. On a broader level, the results highlight a need to consider non-random and incomplete supply as a factor when examining observed uptake of agricultural innovations.

Innovations in food home delivery systems have seen rapid growth in the consumption of food prepared outside the home. Such food is often higher in negative nutrients than home-prepared food. Technological advancements in the transport sector are set to amplify the availability of food delivery services via the introduction of autonomous (driverless) vehicles. Very little is known about how consumers are likely to react to this change, and relevant regulatory frameworks are lacking. To address this evidence gap and inform policy in this emerging domain, the aim of the present study was to provide preliminary insights into how and why consumers may choose to use autonomous food delivery services once they are widely available and the potential impacts on their diets. A sample of 100 adults currently residing in Australia participated in one-to-one interviews. Quotas were applied for the attributes of age, sex, and geographical location to ensure appropriate demographic distribution. Around two-thirds of interviewees reported intending to use autonomous food delivery services for receiving groceries and around one-half for receiving fast food. Perceptions of increased convenience dominated interviewees’ expressed reasons for intending to use autonomous delivery services. Overall, interviewees saw few impediments to the widescale use of autonomous delivery services, and some expected to consume more unhealthy food due to increased access. While autonomous delivery services have the potential to substantially increase access to both healthy and unhealthy food products, effective policy actions are needed to ensure health outcomes are optimized.

Poor diet quality increases risks for non-communicable diseases. Interventions that leverage insights from psychology and economic theory are hypothesized to improve diet quality. This study tested the incremental effectiveness of these approaches using a fully operational online grocery store. We conducted a 3-arm crossover trial involving actual purchases with 187 primary grocery shoppers for households randomly exposed to: (1) Arm 1: control store, (2) Arm 2: store with a cost-free social norm-based behavioral intervention, built upon using Nutri-Score (NS), an evidence-based Front-of-Pack (FOP) interpretive label, and (3) Arm 3: Arm 2 plus a loss-framed financial incentive of SGD 5. Nutritional quality measures, including the average quality of the shopping basket based on the validated NS algorithm (primary), were used to assess intervention effectiveness using a linear mixed-effect model with repeated measures. The social norm-based behavioral intervention led to a statistically significant 4.62-point [95% CI: 3.73, 5.52] increase in the weighted average NS of the shopping basket, relative to Control. Adding the 5 SGD incentive increased effectiveness by an additional 2.49-point [CI: 1.61, 3.37]. These changes are equivalent to improving diet quality of the shopping basket, relative to Control, from NS grade low C to grade high C for Arm 2 and to Grade B for Arm 3. These findings suggest that interventions leveraging insights from behavioral science have the potential to improve nutritional quality at little to no additional cost and should be considered for adoption.

When food inflation reached high levels in 2018 in Turkey, municipality-run discount stalls were introduced in Istanbul and Ankara to lower consumer prices. These stalls create a short food supply chain (SFSC) by eliminating intermediaries between producers and consumers. In this study, using a regression discontinuity design (RDD), we analyze the impact of municipality-run discount stalls on the price formation in each level of fresh fruits and vegetables supply chain: producers, wholesale markets, retailers and outdoor farmers markets. In line with the policy intentions, retail prices fell significantly after implementation. On the other hand, the additional retail demand appears to have increased producer and wholesale prices.

The affordability of nutritious food for “all people, at all times” is a critically important dimension of food security. Yet surprisingly, timely high-frequency indicators of food affordability are rarely collected in any systematic fashion despite price volatility emerging as major source of food insecurity in the 21st Century. The 2008 global food crisis prompted international agencies to invest heavily in monitoring domestic food prices in low and middle income countries (LMICs). However, food price monitoring is not sufficient for measuring changes in diet affordability; for that, one must also measure changes either in income or in an income proxy. We propose using the wages of unskilled workers as a cheap and sufficiently accurate income proxy, especially for the urban and rural non-farm poor. We first outline alternative measures of “food wage” indices, defined as wages deflated either by consumer food price indices or novel healthy diet cost indices. We then discuss the conceptual strengths and limitations of food wages. Finally, we examine patterns and trends in different types of real food wage series during well-known food price crises in Ethiopia (2008, 2011 and 2022), Sri Lanka (2022) and Myanmar (2022). In all these instances, food wages declined by 20–30%, often in the space of a few months. In Myanmar, the decline in real wages during 2022 closely matches declines in household disposable income. We strongly advocate tracking the wages of the poor as a timely, accurate and cost-effective means of monitoring food affordability for important segments of the world’s poor.
