In many developing and developed countries, the minimum pension program is a key welfare program and...

We show that Covid-19 illnesses persistently reduce labor supply. Using an event study, we estimate that workers with week-long Covid-19 work absences are 7 percentage points less likely to be in the labor force one year later compared to otherwise-similar workers who do not miss a week of work...

Billions of women still face legal barriers to economic inclusion, yet it is unclear whether lifting these barriers is sufficient to enhance their economic participation.
