Not long ago securities were traded by human traders in face-to-face markets. The ecosystem of an open outcry market was well-known, visible to a human eye, and rigidly prescribed. Now trading is increasingly done in anonymous electronic markets where traders do not have designated functions or...

We study the motivations of traders in the interbank market around the 2007-09 subprime crisis. We develop a new methodology that reveals the underlying urgency to borrow overnight funds, which we call Trading Urgency. We find that the dispersion of beliefs (market Sidedness) and Trading Urgency...

Network analysis has become a key framework in financial economics in understanding how interconnectedness among market participants results in spillovers, amplifies or absorbs shocks, and creates other nonlinear effects that ultimately impact market health. In this paper, we propose a new...

We study the behavior of the interbank market before, during and after the 2008 financial crisis. Leveraging recent advances in network analysis, we study two network structures, a correlation network based on publicly traded bank returns, and a physical network based on interbank lending...

Problem definition: The effect of the minimum wage is an important yet controversial topic that has received attention for decades. Our study is the first to take an operational lens and empirically study the impact of the minimum wage on firms' scheduling practices. Methodology/results: Using a...

We develop and present a new methodology to detect regime changes within a sequence of sparse networks that have overlapping and evolving community structure. The core of the methodology is a non-negative matrix factorization that maximizes a Poisson likelihood subject to a penalty that accounts...

Proximity between stores in franchise networks that share the same brand is a highly contentious issue. A high-performance store may have different impacts on its proximal peer stores from a negative impact, such as potential cannibalization, to a positive impact, such as improved brand...

Problem Definition: Consider a network of stores operating under the same brand, for example, a chain of coffee shops or banks. Increasing sales at one store may have a different impact on the sales of another store: from a negative impact as a result of potential cannibalization to a positive...
