Lebanon is the country with the highest density of refugees in the world, raising the question of whether the host and refugee populations can cooperate harmoniously. We conduct a lab-in-thefield experiment in Lebanon studying intra- and inter-group behavior of Syrian refugees and Lebanese...

Institutions are important for proper economic performance, but are replaceable by trust or other social norms. We show that when proper institutions and trust are missing, integrity of the individuals can replace them. We construct a model of a transactions-based economy with contracts...

Religious divisions have long played a primary role in major conflicts throughout much of the world. Intergroup contact may increase trust between members of different religions. However, evidence on how inter-religious contact affects individuals' behavior towards one another is scarce. We...

This study examines the causal joint effect of a new political regime and war against Iraq on life expectancy of Iranians for the period 1978–1988 during the revolution and war. I use a synthetic control approach to construct a synthetic Iran based on a weighted average of other Middle East...

We introduce a novel methodology for adaptive targeted experiments. Our Tempered Thompson Algorithm balances the goals of maximizing the precision of treatment effect estimates and maximizing the welfare of experimental participants. A hierarchical Bayesian model allows us to adaptively target...

When did Germany become economically integrated? Within the framework of a gravity model, based on a new data set of about 40,000 observations on trade flows within and across the borders of Germany over the period 1885-1933, I explore the geography of trade costs across Central Europe. There...

An emerging literature on the geography of bohemians argues that a region's lifestyle and cultural amenities explain, at least partly, the unequal distribution of highly qualified people across space, which in turn, explains geographic disparities in economic growth. However, to date, there has...

This paper explores the idea that institutional details matter and that attempts to estimate the economic effects of federalism by employing a simple dummy variable neglect potentially important institutional details. Based on a principal component analysis, seven aspects of both federalism and...

This paper seeks to reconcile two seemingly contradictory strands in the literature on economic development in the late nineteenth century Habsburg Empire - one emphasizing the centrifugal impact of rising intra-empire of nationalism, the other stressing significant improvements in market...

Existing evidence, mostly from British textile industries, rejects the importance of formal education for the Industrial Revolution. We provide new evidence from Prussia, a technological follower, where early-19th-century institutional reforms created the conditions to adopt the exogenously...
