The barriers faced by Chinese rural-urban migrants to access social services, particularly education, in host cities could help explain why the majority of migrants choose to leave their children behind. This paper proposes a theoretical framework that allows for an explicit discussion of the...

This paper studies how wealth and health inequalities have interacted with the Covid-19 epidemic in a way that has reinforced inequalities in income, savings, epidemic risk and even individual preventive behaviors. We present in more detail two papers and their theoretical and empirical results....

This paper evaluates how Vietnam's Escuela Nueva (VNEN) program, an educational reform for primary schools supported by the World Bank, affected the cognitive (mathematics and Vietnamese) and non-cognitive (socioemotional) skills of students in that country. We use propensity score matching to...

The barriers faced by Chinese rural-urban migrants to access social services, particularly education, in host cities could help explain why the majority of them choose to leave their children behind. We identify the causal impacts of school fees by instrumenting for it with unexpected shocks to...

Little evidence currently exists on the effects of COVID-19 on air quality in poorer countries, where most air pollution-linked deaths occur. We offer the first study that examines the pandemic's impacts on improving air quality in Vietnam, a lower-middle income country with worsening air...

Despite a sizable population and modest status as a low middle-income country, Vietnam has recorded a low COVID-19 fatality rate that rivals those of richer countries with far larger spending on health. We offer an early review of the emerging literatures in public health and economics on the...

Despite a growing literature on the impacts of the COVID-19 pandemic, scant evidence currently exists on its impacts on air quality. We offer the first study that provides cross-national evidence on the causal impacts of COVID-19 on air pollution. We assemble a rich database consisting of daily,...
