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...

While the direct impact of geographic endowments on prosperity is present in all countries, in former colonies, geography has also affected colonization policies and, therefore, institutional outcomes. Using non-colonized countries as a control group, I re-examine the theories put forward by La...

Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of human from Africa tens of...

Formal or informal institutions have long been adopted by societies to protect against opportunistic behavior. However, we know very little about how these institutions are chosen and their impact on behavior. We experimentally investigate the demand for different levels of institutions that...

We propose and apply methods to quantify the impact of national institutions on international trade and development. We are able to identify the direct impact of country-specific institutions on international trade within the structural gravity framework. Our approach naturally addresses the...

To investigate the relation between trust and formal institutions, we analyze bilateral trade patterns in a sample of 16 European countries between 1996-2009. Trust in trading partners has a significant positive effect on bilateral trade. However, our results suggest that trust and formal...

The effects of ethnic geography, i.e., the distribution of ethnic groups across space, on economic, political and social outcomes are not well understood. We develop a novel index of ethnic segregation that takes both ethnic and spatial distances between individuals into account. Importantly, we...
