The goal of many experiments is to inform the choice between different policies. However, standard experimental designs are geared toward point estimation and hypothesis testing. We consider the problem of treatment assignment in an experiment with several non-overlapping waves, where the goal...

This paper considers a marriage market with two-sided search and transferable utility in which the match payoff depends on age. It characterizes a set of payoff functions consistent with two salient marriage age patterns, (1) assortative matching by age, and (2) “differential age matching,”...

If women marry younger than men, increased population growth causes a surplus of women in the marriage market. This paper introduces search frictions into a matching model with transferable utility and age-dependent match payoffs to study if this so-calledmarriage squeeze has caused a dowry...

Multiple price lists are a convenient tool to elicit willingness to pay (WTP) in surveys and experiments, but choice patterns such as "multiple switching" and "never switching" indicate high error rates. Existing measurement approaches often do not provide accurate standard errors and cannot...

Overconfident: How Economic and Health Fault Lines Left the Middle East and North Africa Ill-Prepared to Face COVID This report examines the region's economic prospects in 2021, forecasting that the recovery will be both tenuous and uneven as per capita GDP level stays below pre-pandemic levels....

This report examines the region's economic prospects in 2021, forecasting that the recovery will be both tenuous and uneven as per capita GDP level stays below pre-pandemic levels. COVID-19 was a stress-test for the region’s public health systems, which were already overwhelmed even before the...

This study conducted an experiment in Mali to test whether patients pressure doctors to prescribe medical treatment they do not necessarily need. The experiment varied patients’ information about a discount for antimalarial tablets and measured demand for both tablets and costlier antimalarial...
