Correcting misperceptions about support for social distancing to combat COVID-19

Correcting misperceptions about support for social distancing to combat COVID-19

Can informing people of high community support for social distancing encourage them to do more of it? We randomly assigned a treatment to correct individuals’ underestimates of community support for social distancing. In theory, informing people that more neighbors support social distancing than expected encourages free riding and lowers the perceived benefits from social distancing. At the same time, the treatment induces people to revise their beliefs about the infectiousness of COVID-19 upward; this perceived-infectiousness effect and the norm-adherence effect increase the perceived benefits from social distancing. We estimate the effects on social distancing, which are measured by using a combination of self-reports and reports of others. While experts surveyed in advance expected the treatment to increase social distancing, we find that its average effect is close to zero and significantly lower than expert predictions. However, the treatment’s effect is heterogeneous as predicted by theory: it decreases social distancing where current COVID-19 cases are low (where free riding dominates) but increases it where cases are high (where the perceived-infectiousness effect dominates). These findings highlight that correction of misperceptions may have heterogeneous effects depending on disease prevalence.

Emerging outsource agricultural services enable farmer adaptation in agrifood value chains: A product cycle perspective

Outsource agricultural service enterprises emerged a century ago in high-income countries and in the past several decades in developing regions. We contribute by analyzing and illustrating the emergence of these services from the perspective of phases of the Product Cycle. These services help farmers adapt to international and domestic agrifood value chains: (1) in the commoditization phase, e.g., with rice combine harvesting services in China and Myanmar for domestic and export markets; (2) in the early product differentiation phase into quality traits, e.g., with horticultural services to Ethiopian and Indonesian farmers for urban wholesale markets; (3) in the advanced product differentiation phase into environmental traits, e.g., with A-Z services to help French farmers grow eco-labeled vegetables for supermarkets. These services addressed farmers’ shortfalls in information, skills, labor, and equipment. The services are supplied by medium/large farmers with excess capacity say of a combine; by wholesalers who want to reduce search costs and risks; by input “agro-dealers”; and by agribusinesses servicing their outgrowers. In new cases shown in France, outsource firms partner with farm input companies such as Bayer or with robot/drone companies. Governments have – and can do much more to – support the emergence of these services such as in developing regions today through: (1) promotion of a business ecosystem, based on policies of investment in hard and soft infrastructure, favoring the coadaptation of these firms with farmers’ needs; (2) policies facilitating access, such as through import liberalization, of equipment and seeds and chemicals.

The importance and determinants of purchases in rural food consumption in Africa: implications for food security strategies

The importance and determinants of purchases in rural food consumption in Africa: implications for food security strategies

We analyze rural households’ purchases of food (cereals and non-cereals) in Sub-Saharan Africa using nationally representative data with 65,000 observations covering 7 countries over a decade. We distinguish between three strata of countries: lower stratum in income and urbanization, middle stratum, and upper stratum. The paper breaks ground by the breadth and time length of the sample. We find that purchases form the majority of rural food consumption whether in favorable or unfavorable agroecological zones and over country and income strata and for most food products. Rural nonfarm employment (as a cash source) plays an important role in household food purchases across all study countries and food products. Policy implications include the importance of food purchase markets and supply chains to and in rural areas as well as nonfarm employment.

Assessments of the Impacts of COVID-19 on Myanmar’s food security and welfare

While a much stronger second wave of COVID-19 cases poses a serious and sustained threat to the health of the Myanmar population, it also brings renewed economic disruptions and poses new challenges for efforts to avert poverty, food insecurity, and malnutrition. To generate evidence that can better inform the design of emergency response and economic […]

COVID-19 and Food Market Disruptions in Myanmar

The rise of COVID-19 infections and policies imposed to control the spread of the disease might have created significant food market disruptions. Disruptions in food markets are an obvious concern, given the importance of agricultural prices for the income of farmers and food prices for the already lower purchasing power – due to reduced incomes […]
