Preface: What Is Narrative Economics? 1. Allen, 1964 [1931], p. 261. 2. Allen, 1964 [1931], p. viii. 3. “Descriptive economics again divides into a formal and narrative branch; of which the former analyzes and classifies the conceptions needed for understanding the science in its widest applications, and the latter investigates historically and comparatively the various forms of economic life exhibited by different communities and at different epochs” (within entry “Method of Economics”), Palgrave, 1894, p. 741. 4. Interest in the role of narratives in driving social movements has been expressed by sociologists in the New Social Movement literature; see Davis, 2002. 5. Fair and Shiller (1989) show evidence that forecasting models have some ability to forecast in the short run, but Lahiri and Wang (2013) show with the Philadelphia Federal Reserve Bank Survey of Professional Forecasters that there is no “significant skill” at attaching a probability to a one-quarter GDP decline in the United States one year in the future. The probability of GDP decline that the professionals as a group have been giving at this forecast horizon is worthless. 6.

She won the Nobel Peace Prize in 1931. 12. Keynes, 1920 [1919], p. 268. 13. My publications started with my 1972 doctoral dissertation at the Massachusetts Institute of Technology entitled “Rational Expectations and the Structure of Interest Rates.” That dissertation, written under the supervision of Franco Modigliani, who influenced me in trying to find a realistic grounding for economic theories, was not fully comfortable with the economists’ favorite notion that all people are rational and consistent maximizers. Soon thereafter I wrote “Rational Expectations and the Dynamic Structure of Macroeconomic Models: A Critical Review” (1978). I continued with “Stock Prices and Social Dynamics” (1984); Irrational Exuberance (first edition, 2000); and two books coauthored with George Akerlof, Animal Spirits: How Human Psychology Drives the Economy and Why It Matters for Global Capitalism (2009), and Phishing for Phools: The Economics of Manipulation and Deception (2015).

Chapter 2. An Adventure in Consilience 1. For example, calls for a broader approach to economic research have asked for the study of “social dynamics” and “popular models” (Shiller, 1984), “culturomics” (Michel et al., 2011), or “humanomics” (McCloskey, 2016); or for more “narrativeness” (Morson and Schapiro, 2017) or for “fictional expectations” (Beckert and Bronk, 2018) or “diagnostic expectations” (Gennaioli and Shleifer, 2018), “policy legends and folklists” (Fine and O’Neill, 2010), or “information-processing difficulty” in responding to news that makes “changes in expectations” into “an independent driver of economic fluctuations” (Beaudry and Portier, 2014). 2.
