Stephen joined UEBS in 2020 after completing a three-year position as a postdoctoral prize research fellow at Nuffield College/University of Oxford. He received his PhD from Stanford University in 2017.
Stephen’s research focuses on the application of network science to economics with a particular emphasis on applied microeconomic theory. He is also interested in other areas of applied micro theory such as matching and in behavioral and experimental economics.

Stephen’s main research interest is social and economic networks, particularly as a means for modelling social learning. He is also interested into the insights of behavioral economics for learning and into the use of experimental and empirical methods to refine theories and motivate modelling.
Research projects
Stephen is currently working on a theoretical model of how individuals choose from whom to learn in the presence of real-world frictions to the communication of information. To test the validity of this theory, he is working on a collaboration to analyze network data from a field experiment in Nepal. In addition, he is developing a lab experiment to test for how well individuals anticipate the economic choices of others when evaluating the claims they make.

Abstract:
Networks of military alliances, wars, and international trade
Significance
. The incidence of interstate wars has dropped dramatically over time: the number of wars per pair of countries per year from 1950 to 2000 was roughly a 10th as high as it was from 1820 to 1949. This significant decrease in the frequency of wars correlates with a substantial increase in the number of military alliances per country and the stability of those alliances. We show that one possible explanation of this is an accompanying expansion of international trade. Increased trade decreases countries’ incentives to attack each other and increases their incentives to defend each other, leading to a stable and peaceful network of military and trade alliances that is consistent with observed data.
