Ph.D. Candidate in Economics | University of California, Berkeley
I am a fifth year PhD student in Economics at UC Berkeley, interested in Development and Trade. I use large scale experiments and administrative data sets to conduct well-identified empirical research on migration, urbanization, networks, and the effects of cash transfers in general equilibrium.

Despite numerous journalistic accounts, systematic quantitative evidence on economic conditions during the ongoing COVID-19 pandemic remains scarce for most low- and middle-income countries, partly due to limitations of official economic statistics in environments with large informal sectors and subsistence agriculture. We assemble evidence from over 30,000 respondents in 16 original household surveys from nine countries in Africa (Burkina Faso, Ghana, Kenya, Rwanda, Sierra Leone), Asia (Bangladesh, Nepal, Philippines), and Latin America (Colombia). We document declines in employment and income in all settings beginning March 2020. The share of households experiencing an income drop ranges from 8 to 87% (median, 68%). Household coping strategies and government assistance were insufficient to sustain precrisis living standards, resulting in widespread food insecurity and dire economic conditions even 3 months into the crisis. We discuss promising policy responses and speculate about the risk of persistent adverse effects, especially among children and other vulnerable groups.

In the absence of concrete plans for widespread vaccination, masks remain one of the few tools available to low-income populations to avoid the spread of SARS-CoV-2 for the foreseeable future. We compare mask use data collected through self-reports from phone surveys and direct observations in public spaces from population-representative samples in Ugunja subcounty, a rural setting in Western Kenya. We examine mask use in different situations and compare mask use by gender, age, location, and the riskiness of the activity. While only 12% of people admitted in phone interviews to not wearing a mask in public, 90% of people we observed did not have a mask visible in public spaces despite a national government mandate. Self-reported mask use was significantly higher than observed mask use in all scenarios (i.e. in the village, in the market, on public transportation). This vast gap suggests that people are aware that mask use is socially desirable, but in practice they do not adopt this behavior. Focusing public policy efforts on improving adoption of mask use via education and behavioral interventions may be needed to improve compliance. Methodologically, our findings suggest that the reliance on self-reported adherence to mitigation measures from phone surveys may be problematic.

How large economic stimuli generate individual and aggregate responses is a central question in economics, but has not been studied experimentally. We provided one-time cash transfers of about USD 1000 to over 10,500 poor households across 653 randomized villages in rural Kenya. The implied fiscal shock was over 15 percent of local GDP. We find large impacts on consumption and assets for recipients. Importantly, we document large positive spillovers on non-recipient households and firms, and minimal price inflation. We estimate a local fiscal multiplier of 2.6. We interpret welfare implications through the lens of a simple household optimization framework.

The Effects of Social Networks on Labor Market Outcomes: Panel evidence from the Random Placement of Refugees in Switzerland
with Daniel Auer and Johannes Kunz
We study the effects of social and professional networks on the labor market integration of asylum seekers in Switzerland using monthly employer-employee matched administrative data from 2008 to 2018. Upon arrival, the universe of 600’000 asylum seekers arriving in Switzerland after 2000 are randomly allocated to one of 26 cantons (absent a reunion with immediate family or health reasons). We study how the structure (size, composition, etc.) of their ethnic, national and professional networks (instrumented by initial random placement) dynamically affects their labor market outcomes over time.
Labor Market Integration, Growth and Inequality: Evidence from China's Hukou Reforms
with Wei Lin
Successive reforms to China's local registration system, the Hukou, provide variation in group-specific migration costs across time and space. We use this variation, together with an event-study design and triple-difference identification strategy, to quantify the reforms' contribution to the increase in internal migrant labor over the past 20 years in China. Using policy-induced exogenous by-group bilateral migration flows, we estimate the impact of increased labor market integration on aggregate Chinese productivity growth, as well as inequality across types of workers and different regions between 1995 and 2015. In the process, we develop a new methodology and provide new estimates of the migration elasticity for different types of workers, between-group substitutability of workers, and across-group productivity and amenity spillovers.
Other work in progress
MaskUp: Encouraging Mask Use through Community-Based Mask Distribution and Education in Kenya and Uganda (with Alexandra Jakubowski, Michael Walker) Two RCTs studying strategies to adopt mask use through community-level mask distribution, education, behavioral nudges and role-model interventions during the COVID-19 pandemic in Kenya and Uganda.
Balancing Work and Childcare: Evidence from COVID-19 School Closures and Re-openings in Kenya (with Pierre Biscaye and Utz Johann Pape) We use partial school re-openings during the COVID-19 pandemic to study the impact of childcare on parents' labor supply.
Long-run equilibrium effects of cash transfers (with Johannes Haushofer, Ted Miguel, and Michael Walker). We study how large inflows of cash affect the economy in the long run. Do effects dissipate? Are there agglomeration effects? Does market structure change?
Does money buy influence? We use a large randomized cash transfer program to estimate the social network effects of cash. How does your social network and political influence change when you, or members in your network, get exogenously richer?
Reciprocity in assimilation? (with Daniel Auer and Johannes Kunz). Using the random assignment of asylum seekers to locations in Switzerland, we study how assimilation of migrants, proxied by newborn names, interacts with exposure effects on the host population.
Genocide and the Demand for Formal Institutions: Evidence from the Legacy of the Khmer Rouge (with Ricardo Dahis and Joris Mueller). How does a legacy of violence and expropriation shape the demand for current property rights?
