Bio

Valerie Mueller is a Nonresident Fellow in the Development Strategies and Governance Unit and an Associate Professor in the School of Politics and Global Studies at Arizona State University. Prior to joining the university, she was a Senior Research Fellow at IFPRI in Washington, DC.

Mueller’s research falls largely into three main themes. The first quantifies rural household vulnerability to climate variability, focusing on migration, nutrition, and health markers in Africa and Asia. The second area uses randomized controlled trials to identify mechanisms to improve the delivery of rural services (legal justice for women, agricultural extension, and the equitable allocation of irrigation water) in East African countries. Her third area of research focuses on the prospects of youth employment in Africa. She has a co-edited volume published at Oxford University Press in 2019, which studies the evolution of youth employment and its role in the structural transformation process in Africa.

Mueller’s research contributions have been featured in Nature Climate Change, Proceedings of the National Academy of Sciences, American Economic Review, American Journal of Agricultural Economics, and the Journal of Development Economics, and have received significant media coverage in over 15 major media outlets (including Le Monde, Science, and Scientific American). Despite her presence in the research community, she remains involved in the field and aims to provide relevant technical expertise by repeated interaction with donor communities, local policymakers, and government officials.

Social assistance and adaptation to flooding in Bangladesh

Social assistance and adaptation to flooding in Bangladesh

As climate change exacerbates weather shocks, there is growing interest in understanding whether social assistance programs can support coping among poor rural households and whether program effects vary by gender. We assess whether a social assistance program – the Transfer Modality Research Initiative (TMRI) –influenced the effects of prior monsoon flooding on household consumption and adult diets in southern Bangladesh. TMRI provided cash or food transfers, with or without nutrition behavior change communication, from 2012-2014. Within the study sites and years, flooding was substantial but moderate. Our findings suggest that, without TMRI, a one-standard-deviation increase in lagged flooding led to households smoothing consumption by drawing down savings and reducing diet quality among both men and women. In contrast, among TMRI treatment households, lagged flooding did not reduce savings, and both men’s and women’s diet quality improved. Effects on diet quality appeared largely driven by legumes and by fruits and vegetables, and improvements appeared strongest among households receiving both transfers and behavior change communication. Results indicate that social assistance can help households cope with effects of moderate flooding in southern Bangladesh, protecting household savings and improving both men’s and women’s diets.

Rainy day funds? How men and women adapt to heavy rainfall shocks and the role of cash transfers in Mali

Rainy day funds? How men and women adapt to heavy rainfall shocks and the role of cash transfers in Mali

Weather shocks can affect men and women differently, due in part to differences in their adaptive capacities. We merge weather data with survey data from a randomized control trial of a cash transfer program in Mali to describe how men and women cope with weather shocks and the role of cash transfer programs in supporting adaptive responses. We find that heavy rainfall reduces household’s consumption but that the cash transfer program mitigates these impacts, primarily by allowing households to draw down both men’s and women’s savings, increasing the value of livestock and farming assets held jointly by men and women, and facilitating a reallocation of men’s and women’s labor to livestock production and women’s labor to domestic work.

Leveraging unsupervised machine learning to examine women’s vulnerability to climate change

Leveraging unsupervised machine learning to examine women’s vulnerability to climate change

We provide an application of machine learning to identify the distributional consequences of climate change in Malawi. We compare climate impact estimates based on drought indicators established objectively from the k-means algorithm to more traditional measures. Young women affected by drought were 5 percentage points more likely to be married by 18 than those living in nondrought areas. Our approach generates robust results when varying the number of clusters and definition of treatment status. In some cases, we find the design using k-means to define treatment is more likely to satisfy the assumptions underlying the difference-in-differences strategy than when using arbitrary thresholds. Projections from the estimates indicate future drought risk may lead to larger declines in labor productivity due to women’s engagement in early age marriage than other factors affecting their participation rates. Under the extreme representative concentration pathway scenario, drought exposure encourages the exit of 3.3 million women workers by 2100.

Youth and Jobs in Rural Africa: Beyond Stylized Facts

The share of working-age young people in Africa south of the Sahara has risen due to past declines in mortality coupled with high fertility. This “youth bulge” has created a sense of urgency among national governments and the international development community as the prospect of widespread youth unemployment in Africa, and the social instability and […]
