Abstract

We estimate the causal effects of index insurance coverage on subjective well-being among livestock herders in southern Ethiopia. By exploiting the randomized distribution of discount coupons and information treatments to instrument for the purchase of index-based livestock insurance, and three rounds of panel data, we separately identify ex ante welfare gains from insurance that reduces risk exposure and ex post buyer's remorse effects that may arise after the resolution of uncertainty. We find that current insurance coverage generates subjective well-being gains that are significantly higher than the buyer's remorse effect of an insurance policy that lapsed without paying out. Given the positive correlation in insurance purchase propensity over time, failure to control for potential buyer's remorse effects can bias downward estimates of welfare gains from current insurance coverage.

Abstract

As COVID-19 continues to wreak havoc across the world, researchers are attempting to quantify the economic fallout from the pandemic as it continues to unfold. Estimating the economic impacts of a prevailing pandemic is fraught with uncertainties about the epidemiology of the disease and the breadth of disruption of economic activities. This paper employs historical and near real-time Google search data to estimate the immediate impacts of COVID-19 on demand for selected services across 182 countries. The analysis exploits the temporal and spatial variations in the spread of the virus and finds that demand for services that require face-to-face interaction, such as hotels, restaurants and retail trade, has substantially contracted. In contrast, demand for services that can be performed remotely or provide solutions to the challenges of reduced personal interactions, such as information and communications technology (ICT), and deliveries, has increased significantly. In a span of three months, the pandemic has resulted in a 63 percent reduction in demand for hotels, while increasing demand for ICT by a comparable rate. The impacts appear to be driven by supply contractions, due to social distancing and lockdown measures, and demand shocks as consumers shelter in place, with the latter dominating for most services. The magnitude of the changes in demand varies considerably with government responses to the pandemic.

Abstract

The COVID-19 pandemic has spurred interest in the use of remote data collection techniques, including phone surveys, in developing country contexts. This interest has sparked new methodological work focusing on the advantages and disadvantages of different forms of remote data collection, the use of incentives to increase response rates, and how to address sample representativeness. By contrast, attention given to associated response fatigue and its implications remains limited. This study designed and implemented an experiment that randomized the placement of a survey module on women's dietary diversity in the survey instrument. The study also examines potential differential vulnerabilities to fatigue across food groups and respondents. The findings show that delaying the timing of mothers' food consumption module by 15 minutes leads to 8-17 percent decrease in the dietary diversity score and a 28 percent decrease in the number of mothers who consumed a minimum of four dietary groups. This is driven by underreporting of infrequently consumed foods; the experimentally induced delay in the timing of mothers' food consumption module led to decreases of 40 and 11 percent in the reporting of consumption of animal source foods and fruits and vegetables, respectively. The results are robust to changes in model specification and pass falsification tests. Responses by older and less educated mothers and those from larger households are more vulnerable to measurement error due to fatigue.

Abstract

Digital technologies can expand access to health services to underserved populations. This paper leverages mobile network expansion and survey data spanning two decades to study the impact of access to mobile phones on infant mortality in Africa. Using plausibly exogenous variations in lightning intensity and (sub)regional convergence in mobile penetration as instrumental variables for mobile network expansion, the analysis finds that mobile phones significantly reduce infant mortality. A 10 percentage point increase in mobile coverage is associated with a 0.45 percentage point reduction in infant mortality. Improvements in health knowledge and behavior and health care utilization appear to be plausible channels.

Abstract

This paper assesses the impact of Ethiopia's flagship social protection program, the Productive Safety Net Program on the adverse impacts of the COVID-19 pandemic on the food and nutrition security of households, mothers, and children. The analysis uses pre-pandemic, in-person household survey data and a post-pandemic phone survey. Two-thirds of the respondents reported that their incomes had fallen after the pandemic began, and almost half reported that their ability to satisfy their food needs had worsened. Employing a household fixed effects difference-in-difference approach, the study finds that household food insecurity increased by 11.7 percentage points and the size of the food gap by 0.47 months in the aftermath of the onset of the pandemic. Participation in the Productive Safety Net Program offsets virtually all of this adverse change - the likelihood of becoming food insecure increased by only 2.4 percentage points for Productive Safety Net Program households and the duration of the food gap increased by only 0.13 month. The protective role of the program is greater for poorer households and those living in remote areas. The results are robust to various definitions of program participation, different estimators, and different ways of accounting for the non-randomness of mobile phone ownership. Productive Safety Net Program participants were less likely to reduce expenditures on health and education by 7.7 percentage points and less likely to reduce expenditures on agricultural inputs by 13 percentage points. By contrast, mothers' and children's diets changed little, despite some changes in the composition of diets, with consumption of animal source foods declining significantly.
