Self-selection into healthcare options biases estimates of the effects of healthcare on health outcomes. We exploit exogenous variation in the cost of formal-sector care to show that the use of such care improves short-term health outcomes for acutely ill children in Tanzania. Better...

I show that malaria misdiagnosis, common in resource-poor settings, decreases the expected effectiveness of an important new therapy - since only a fraction of treated individuals have malaria - and reduces the rate of learning via increased noise. Using pilot program data from Tanzania, I...

Productivity differences across firms and countries are surprisingly large and persistent. Recent research reveals that the country-level distributions of productivity and quality of management are strikingly similar, suggesting that management practices may play a key role in the determination...

How do parents contend with threats to the health and survival of their children? Can the social safety net mitigate negative economic effects through transfers to affected families? We study these questions by combining the universe of cancer diagnoses among Danish children with register data...

Conjoint experiments (CEs) provide designers with insights into consumer preferences and are one of several user-based design approaches aimed at meeting users' needs. Traditional CEs require participants to evaluate products based on two-dimensional (2D) visual representations or written lists...
