This study provides a comprehensive systematic review of recent randomized controlled trials (RCTs) to evaluate the employment effects of skills training programs in sub-Saharan Africa, a region where such interventions are a key element of development assistance. The review focuses on studies...

Improving youth labor market outcomes is a primary concern for countries around the world. We conduct a randomized controlled trial in Tanzania on an intense gender-sensitive skills training program that worked with over 53,000 youth in the region. After two years, we find the program increased...

Very little is known about the efficient collection of fines despite their indispensable contribution to local government budgets. This paper fills an important gap in the literature by studying the effectiveness of deterrence (enforcement) and non-deterrence (social norms) letters that aim to...

Interventions led by non-governmental organizations (NGOs) are often more effective than comparable efforts by other actors, yet relatively little is known about how implementer identity drives final outcomes. Combining a stratified field experiment in India with a triple-differences estimation...

Field experiments which test the application of behavioural insights to policy design have become popular to inform policy decisions. This study is the first to empirically examine who and what drives these experiments with public partners. Through a mixed-methods approach, based on a novel...

This paper provides theoretical and empirical evidence on the implications of the timing of reminders by studying the effect of varying the timing of reminder letters to taxpayers on their payment behavior. The collection of unpaid tax debts constitutes a considerable challenge for tax...
