Title:
A bird’s-eye view into the origin of systemic risk: Financial Institutions, Sovereign Debt, and Public Health and Policy
Abstract:
As economic entities become increasingly interconnected, shocks in financial and economic networks can provoke significant cascading failures throughout the system. To study systemic risk, we model financial institutions' relationships, economic dependencies, and production flows to propose a cascading failure model describing the risk propagation process during crises. We find that our model efficiently identifies a significant portion of the failed banks reported by the Federal Deposit Insurance Corporation during the Global Financial Crisis of 2008. We also study the European sovereign debt crisis of 2009-2012 and observe that the results closely match real-world events (e.g., the high risk of Greek sovereign bonds and Greek banks' distress). We propose an institutional, systemic importance ranking, BankRank, for the financial institutions analyzed in the European bank study to assess individual banks' contribution to the overall systemic risk. Finally, we propose a dynamic cascade model to investigate the systemic risk posed by sector level industries within the U.S. inter-industry network. We then use this model to study the effect of the disruption presented by COVID-19 during 2020 on the U.S. economy. We impose an initial shock that disrupts one or more industries' production capacity and calculates the propagation of production shortage with a modified Cobb-Douglas production function. In the case of COVID-19, the initial shock reflects the loss of labor between March and April 2020, as reported by the Bureau of Labor Statistics. These studies suggest that the cascading failure models could be useful for systemic risk stress testing for financial and economic systems. The models could become complementary to existing stress tests and scenario analysis, incorporating the contribution of the interconnectivity of the banks, governments, and industries to systemic risk in time-dependent networks.

Her research focuses on network theory and complexity science in macroeconomics. She conducts a theoretical and applied interdisciplinary research using quantitative approaches for modeling interdependencies of financial networks, banking system dynamics, and global financial crises. More specifically, Vodenska’s research focuses on modeling of early warning indicators and systemic risk propagation throughout interconnected financial and economic networks. She also studies the effects of news announcement on financial markets, corporations, financial institutions, and related global economic systems. She uses neural networks and deep learning methodologies for natural language processing to text mine important factors affecting corporate performance and global economic trends. Prof. Vodenska teaches Investment Analysis and Portfolio Management, International Finance and Trade, Financial Regulation and Ethics, and Derivatives Securities and Markets at Boston University.

Title:
Exploring the Science of Biomedical Science from Discovery to Impact
Abstract:
This presentation explores the biomedical research enterprise from a science of science perspective, focusing on the relationships between research practices, the people who shape them, the policies that govern them, and the public they ultimately aim to serve. A central thread of this work examines the intersection of sex and gender inclusion in research, the advancement of women in science and medicine - and how they may be inextricably related. This talk will explore how sex and gender are included, analyzed, and reported in biomedical research, and how gender disparities within the scientific workforce influences the types of questions asked and how data are reported and analyzed. Together, these dynamics have significant implications for the rigor and reproducibility of research, as well as for health outcomes more broadly. The talk will also reflect on how this science of science perspective can inform ongoing work at Northwestern’s Clinical and Translational Sciences (NUCATS) Institute which aims to improve, innovate, and implement generalizable solutions that enhance the efficiency, quality, and impact of clinical and translational science. The session will conclude with an overview of NUCATS’ initiatives and resources aligned with these goals.

Title:
All-Female and Female-Led Teams Drive More Breakthrough Ideas in Science and Innovation
Abstract:
The increase of female researchers in science over the past decades has initiated many studies on the gender composition of teams and their research outcomes. Substantial evidence underscores the value of including female researchers in science. Yet, their impact on driving new research directions and technological innovation within teams remains underexplored. In this presentation, we analyze over 65 million papers and two million patents spanning 1950-2010. We document the rise in all-female teams and demonstrate that all-female teams consistently produce the highest proportion of disruptive papers. We explore this trend across time periods, team sizes, and fields. We find that despite the overall decline in disruption, notably, all-female teams have the smallest decline in disruption. We analyze publication text, field-specific structural differences, author careers, leadership dynamics, and team dynamics to understand the vital role that all-female teams play in driving breakthroughs.
