We investigate the implications of extra-normal government spending under the COVID-19 pandemic for commercial bank lending growth between 2019Q4 and 2020Q4 in a large sample of over 3000 banks from 71 countries. We control for pre-pandemic structural factors, bank characteristics and government...

This paper examines the association between episodes of large fiscal impulses (expansions and adjustments) and sustainable development indicators (prosperity, resilience, and inclusivity). We provide country studies of Chile, Poland, South Africa, and Thailand, examining the components of...

We evaluate the long-run effects of a decentralized approach to economic development, called community driven development (CDD), a prominent strategy for delivering foreign aid. Notably we revisit a randomized CDD program in Sierra Leone 11 years after launch. We estimate large persistent gains...

In response to the Covid-19 crisis, 186 countries implemented direct cash transfers to households, and 181 introduced in-kind programs that lowered the cost of utilities such as electricity, water, transport, and mobile money. Do cash or in-kind transfers generate greater welfare improvements?...

We trace the linkages between the episodes of fiscal expansion and consolidation in 72 advanced and emerging and developing economies. The findings suggest that fiscal expansions are positively associated with economic growth, which in turn is positively linked with better sustainable...

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...

This study exploits a randomized school health intervention that provided deworming treatment to Kenyan children and utilizes longitudinal data to estimate impacts on economic outcomes up to 20 years later. The effective respondent tracking rate was 84%. Individuals who received 2 to 3...

The WHO has recently debated whether to reaffirm its long-standing recommendation of mass drug administration (MDA) in areas with more than 20% prevalence of soil-transmitted helminths (hookworm, whipworm, and roundworm). There is consensus that the relevant deworming drugs are safe and...
