The novelty-narrative hypothesis is used to understand stock market instability using big data textual analytics of financial news.
Nicholas Mangee is Associate Professor of Finance at Georgia Southern University and Research Associate for the Institute of New Economic Thinking program on Knightian Uncertainty Economics.
'This important book completes a project begun by Keynes long
before The General Theory and overthrows the standard approach to
uncertainty in economics. Its study of narratives, multiple
equilibria, and use of machine learning to extract the contents of
narratives from financial reporting is certain to be of wide
interest and is a real contribution to economics.' George Akerlof,
Nobel Laureate in Economics
'A substantial contribution to operationalizing the narrative
approach to analyzing fundamental uncertainty as an ongoing feature
of the stock market. Uncertainty prevents the definitive
measurement of risk which underpins mainstream macro-finance
models. But Mangee shows how the incidence of uncertainty, its
causes in unforeseen events, and the way in which markets deal with
it through narratives can be analyzed and quantified. The dataset
he has built up is a contribution in itself. This is a thoughtful,
thoroughly-researched exploration of the narrative approach to
embedding fundamental uncertainty in the core of economics and
finance. It should be read attentively by theorists, policy-makers,
and financial practitioners alike.' Sheila Dow, University of
Stirling
'Attempts to escape from economists' equilibrium trap have been
hampered by their conceit of dividing expectations into 'rational'
and 'irrational'. Nicholas Mangee shows, and shows brilliantly,
that in the face of inescapable uncertainty, rational
decision-making is necessarily built on 'novelty and narrative',
not mathematical probability.' Lord Robert Skidelsky, Warwick
University
'It is a fact of life that stock market returns, along with the
innovations that frequently drive them, are the outcome of
unrepeatable and unforeseeable. This book's Novelty-Narrative
Hypothesis helps us understand how these unknowns drive market
outcomes. This book is a treasure trove of information and insights
into the radical uncertainty that drives so much of our economic
experiences. Economists, policy makers, and market participants
should take note.' Dennis Snower, G20 Economic Policy Advisor and
President of Global Solutions Initiative
'To say that this book is timely is a massive understatement -
current events will be dissected with great interest for the coming
decade.' Richard Friberg, Stockholm School of Economics
'This book develops the Novelty-Narrative Hypothesis, a highly
original approach to empirical examination of stock market outcomes
that enables economists, policymakers, and market participants to
better understand unforeseeable change and Knightian uncertainty.
Mangee provides a hitherto unavailable set of tools for extracting
information from historical events and narrative dynamics, which
will be invaluable in academic research and teaching as well as in
making practical policy and business decisions.' Roman Frydman, New
York University
'Mangee provides a solid introduction to a novel approach to
explaining equity instability.' Mark S. Rzepczynski, CFA Institute
