I study sequential contests where the efforts of earlier players may be disclosed to later players by nature or by design. The model has many applications, including rent seeking, R&D, oligopoly, public goods provision, and tragedy of the commons. I show that information about other players'...

When opposing parties compete for a prize, the sunk effort players exert during the conflict can affect the value of the winner's reward. These spillovers can have substantial influence on the equilibrium behavior of participants in applications such as lobbying, warfare, labor tournaments,...

We investigate if, and why, an initial success can trigger a string of successes. Using random variations in success in a real-effort laboratory experiment, we cleanly identify the causal effect of an early success in a competition. We confirm that an early success indeed leads to increased...

We study a model in which two players with opposing interests try to alter a status quo through instability-generating actions. We show that instability can be used to secure longer-term durable changes, even if it is costly to generate and does not generate short-term gains. In equilibrium,...

We investigate the effects of US-imposed trade sanctions on the global trade patterns of sanctioned countries by employing a gravity model that incorporates data spanning from 1980 to 2020 across 79 nations. The results reveal that both partial and complete US sanctions lead to significant...

We are the first to analyze the effect of terror on stock markets by terror ideology. Surprisingly, we find that Islamist terror attacks created significant negative abnormal returns in American and European markets, but the stock market effects of other terror attacks were almost nil. For our...

This paper estimates the impacts of religiosity on criminal activity using a city-wide shock to religious sentiment from a 2015 Papal visit. Using daily data on all reported offences between 2010 and 2015 in Philadelphia at the census tract level and a difference-in-differences approach, we...

This paper investigates whether social media access is associated with increased probability or intensity of ethnic conflict in Myanmar. In this context most people use mobile phones, and particularly the Facebook app, to access the internet. To distinguish the effects of social media from those...
