PIIRS Global Systemic Risk
Research Community at Princeton University

There is no better indicator of increasing globalization than the massive and accelerating increase in international transactions beginning in the late 1970s. These in turn have required the construction of a complex system of global nodes and links providing the channels through which these can flow. The interdependence of massive global interactions and structures has caused systemic risk to increase exponentially in recent times. Tangible risks—in systems as diverse as energy exploration and production, electricity transmission, computer networks, healthcare, food and water supplies, transportation networks, commerce, and finance—now threaten global political, economic, and financial systems that affect citizens of every nation. As a result, the study of risk has the potential to become an important and influential academic and policy field.

The research community on Global Systemic Risk at Princeton University provides structure for a core group of scholars across a wide variety of disciplines to establish a common dialogue in this emerging field. Working as a group, the depth and breadth of their interests will help to establish a comprehensive and cohesive framework for the study of risk and thus move the field forward. The research community has received support from PIIRS and alumni donors and is led by Miguel Centeno, Musgrave Professor of Sociology and a professor of sociology and international affairs.

The community — with a core group of 22 scholars — will frame its multidisciplinary inquiry from a number of vantage points to better understand the nature of risk, the structure of increasingly fragile systems, and the ability to anticipate and prevent catastrophic consequences.

These include:

  • Computer Science
  • Economics
  • Engineering
  • Finance
  • History
  • History of Science
  • Mathematics
  • Operations Research
  • Philosophy
  • Physical Sciences
  • Politics
  • Psychology
  • Public Policy
  • Sociology

More specifically, Global Systemic Risk will focus on the robustness and fragility of global human-made organizational systems and is concerned with risks that have short- to medium-term likelihood and consequences. 

The most obvious example of how interactive systems can lead to risk is the financial crisis of 2007-2008. Over and above regulatory failure and personal malfeasance, the manner in which declines in the real estate values of pockets of American suburbia led to the greatest economic challenge since the Great Depression reflects the interconnectivity and interdependence of financial institutions. The research community argues that other global systems may be subject to the same kind of emergent disruptions: those caused not by the characteristics of any single part, but from the interaction of large numbers of apparently autonomous agents. The global energy system, information networks, and  air and sea transport may increase the efficiency of production and distribution, but may also make these more susceptible to catastrophic failure. Our food and epidemiological security, for example, may be improved by paying greater attention to how the systemic whole comes to represent more than the sum of its parts.

Workshop on "Historical Systemic Collapse" at Princeton University
Miguel Centeno, Princeton University, Workshop Director
Historical study is traditionally centered around culture, societies, peoples, and individual biography. A novel approach we hope to investigate and contribute to the field is to focus on the critical systems within these historical collapses, and which mechanisms and events contributed to or precipitated systemic failure. By providing a comparative analysis of various collapses, we hope to ascertain whether there are systemic failures that are overlooked and undervalued in our modern-day systems. The ultimate goal is to make the systems which underpin our modern civilization more robust and resilient. Many of these historical collapses have decimated populations, and the ultimate goal of the project would be to learn original insights through the lens of systems-thinking towards the goal of preventing the catastrophic loss of life.

Workshop Co-Organizers: Joanna Sterling, Joe Bak-Coleman, Andrew Gersick, Pawel Romanczuk
As populations of social-media sites have soared, online activity has been increasingly central to offline cultural and political events such as the UK’s Brexit vote and the recent US presidential election. In these and other cases, online networks have appeared prone to splintering, drawing individuals into informational "bubbles" that can incubate ingroup/outgroup hostilities and make participants vulnerable to misinformation and propaganda. These developments raise fundamental questions about the nature of virtual social networks and their impacts on our individual and collective well-being. We believe that an interdisciplinary conversation is needed to address these questions, as the phenomena involved range from the neural reward pathways of individuals up to the structural features of global-scale political movements.

Automated decision making and predictive analytics in combination with rapid progress in sensor technology and robotics are likely to change the way individuals, communities, governments and private actors perceive and respond to climate and ecological change. Machine intelligent methods are already today being applied within a number of research fields related to climate change and environmental monitoring. Investments into applications of these technologies in agriculture, forestry and the extraction of marine resources also seem to be increasing rapidly. Here we elaborate the various ways by which machine intelligence is making progress in domains of critical importance for sustainability, with a special emphasis on possible systemic risks. These risks include a) algorithmic bias and allocative harms; b) unequal access and benefits; c) cascading failures and external disruptions; d) mis- and disinformation, and e) trade-offs between efficiency and resilience. We explore these emerging risks and discuss the limitations of current governance mechanisms in addressing the impact of MI risks on sustainability.

Link to ArticleCovid-19’s Socio-Economic Impact on Low-Income Benefit Recipients: Early Evidence from Tracking Surveys (2020)
Diana Enriquez & Adam Goldstein

The Covid-19 pandemic and ensuing economic crisis have introduced manifold dislocations in Americans’lives. Using novel survey data samples of SNAP recipients, we examine the socio-economic insecurities faced by low-income/benefits-eligible households during the early months of the crisis. Three repeated online surveys included measures of perceived and realized housing insecurity, food scarcity, new debt accrual, and recent job loss as indicators of Covid-induced shocks. Food insecurity and debt accrual worsened significantly over the course of April 2020. Job losses also compounded, albeit at a slower rate. The proportion of respondents reporting multiple types of precarity increased over the month. Compared to Latinx and White respondents, Black respondents were more likely to experience Covid-induced precarity across three out of four indicators, and they experienced more types simultaneously on average. The results provide early systematic evidence on the economic impact of the Covid-19 crisis on poor Americans, and racial disparities therein.

Carl T. Bergstrom & Joseph B. Bak-Coleman

Joseph Bak-Coleman, from Princeton's Ecology & Evolutionary Biology department, collaborates with PIIRS GSR on a number of projects. His most recent publication just appeared in Nature, and shows that information flow between individuals in a social network can be ‘gerrymandered’ to skew perceptions of how others in the community will vote — which can alter the outcomes of elections.

Link to BookMaking Electricity Resilient: Risk and Security in a Liberalized Infrastructure (2017)
Antti Silvast

Antti Silvast was a visiting postdoctoral research fellow at the PIIRS Global Systemic Risk research community during the 2014-15 academic year. During this year, he worked to draft a manuscript of his book Making Electricity Resilient: Risk and Security in a Liberalized Infrastructureq, published by Routledge in May 2017. Drawing on multi-sited ethnographic field work, the book unpacks the work of the authorities, electricity companies, and lay persons that keeps energy systems from failing and helps them to recover from disruptions if they occur. It explores a number of sites in so doing: the historical security policy of energy infrastructures; control rooms where electricity is traded and maintained in real time; and electricity consumers in their homes.

Link to ArticleShy of the Character Limit: "Twitter Mood Predicts the Stock Market" Revisited (2017)
Michael Lachanski and Steven Pav
Econ Journal Watch 14(3)

In the 2011 article “Twitter Mood Predicts the Stock Market” by Johan Bollen, Huina Mao, and Xiaojun Zeng, published in Journal of Computational Science, the authors estimated a proprietary measure of Twitter ‘calm’-ness and found that this measure Granger-caused increases in the Dow Jones Industrial Average from February 28, 2008 to November 3, 2008. The paper and related work has attracted attention by journalists, finance practitioners, and academics. In just six years the paper accumulated 2,514 Google Scholar citations and 678 Web of Science citations (as of April 24, 2017). We subject the paper to thoroughgoing scrutiny, including an attempt to replicate the findings in-sample. Using the authors’ subsampling technique, we replicate their sample window (less the since-deleted and hence unavailable tweets) and extend it backwards to include 2007. Constructing multiple measures of Twitter mood using word-count methods and standard sentiment analysis tools, we are unable to reproduce the p-value pattern that they found. We find evidence of a statistically significant Twitter mood effect in their subsample, but not in the backwards extended sample, a result consistent with data snooping. We find no evidence that our measures of Twitter mood aid in predicting the stock market out of sample. Congruously, the hedge fund set up in late 2010 to implement the Twitter mood strategy, Derwent Capital Markets, failed and closed in early 2012.

Link to ReportSystemic Risk in Global Agriculture - Conference Report (2016)
Summary of proceedings of Princeton-Columbia joint-conference held October 24-25, 2014, in Princeton, New Jersey.

The emerging research fields of systemic risk and systems thinking provide insight into understanding and mitigating the current risks and challenges in our global agriculture network. Since the Green Revolution of the mid-20th century, the global agricultural system has become an increasingly complex and interconnected network of networks, which, in spite of massive productivity gains, has become systemically fragile and vulnerable to shocks.  Over the course of two days, 27 scholars from diverse fields came together at Princeton University to discuss topics within the theme of agricultural systemic risk. The goal of this conference was to generate an interdisciplinary conversation among scholars who study agriculture, systems, and risk in order to identify the causes and consequences of agricultural fragility, and to propose solutions for increasing resilience within the agricultural system. This report is a comprehensive overview of the conference proceedings: providing an overview of the current state of the modern agriculture system and outlining the critical risks, potential solutions, and remaining challenges highlighted by the participants. Videos and a full transcript of the conference are available here.

Miguel A. Centeno, Manish Nag, Thayer S. Patterson, Andrew Shaver, and A. Jason Windawi
Annual Review of Sociology pg. 41.

We discuss the increasing interdependence of societies, focusing specifically on issues of systemic instability and fragility generated by the new and unprecedented level of connectedness and complexity resulting from globalization. We define the global system as the set of tightly-coupled interactions that together allow for the continued flow of information, capital, goods, services, and people. Using the general concepts of globality, complexity, networks, and the nature of risk, we analyze case studies of infrastructure, trade, finance, the environment, and epidemiology in order to develop empirical support for this concept of global systemic risk. We seek to identify and describe the sources and nature of such risks and methods of thinking about risks which may inform future academic research and policymaking decisions.

Globalization is a complex process in all senses of the word: it involves potentially millions (if not billions) of actors, has existed in different forms for thousands of years, encompasses a varied set of human relationships from exchanges to conquest, and may produce "emergent" properties that cannot be predicted based on the characteristics of its component parts. How then to understand it without speaking of banal generalities or becoming engrossed in details not relevant to the overall structure? We suggest that using graphics and cartography may represent one productive method. For the past decade, several of us have been working on how to create portals that would assist in the understanding of and research on globalization.

Working Paper by Timothy Besley and PIIRS GSR Research Community member Avinash Dixit

We construct a model with three features important in the context of major environmental catastrophes: (1) the distribution of possible damage has a fat tail, (2) the probability of the catastrophic event increases as greenhouse gases accumulate, (3) a technological solution may emerge making conservation efforts unnecessary. We solve the model numerically for plausible values of the parameters, and evaluate the tradeoffs between alternative policies such as prevention, mitigation, and technological fixes.
