An interesting history of mathematics and its application to economics and the world of high finance.
Mathematician and financial economist Szpiro (Numbers Rule: The Vexing Mathematics of Democracy, From Plato to the Present, 2010, etc.) chronicles the co-evolution of modern finance, physics and statistics.
In 1997, the Nobel Prize was awarded to economists Myron Scholes and Robert Merton for determining “the true value of an option,” just one year before the billion-dollar hedge fund they founded nearly collapsed global financial markets. The prize was based upon their discovery—along with their deceased collaborator Fischer Black—of a formula that laid the basis for computerized derivatives trading. In the author's opinion, despite the spectacular real-world failures of their model, which also contributed to the 2007 economic crisis, on a scientific level, their achievement “is a landmark achievement of the twentieth century.” While this may strike readers as unwarranted hyperbole, Szpiro unravels the complexity of the Black-Scholes equation and its fascinating relationship to Einstein's application of statistics in explaining the random motion of molecules and to Norbert Wiener's discovery of Cybernetics (based on his World War II work on target acquisition). In the case of options, it is option prices rather than molecules that jiggle. The author devotes most of the text to tracing “the historical and intellectual developments that led to the options pricing formula,” beginning more than 300 years ago with the tulip bubble, when frenzied speculators drove the price higher and higher until the bubble burst and buyers defaulted on future contracts.

A psychologist and Nobel Prize winner summarizes and synthesizes the recent decades of research on intuition and systematic thinking.
The author of several scholarly texts, Kahneman (Emeritus Psychology and Public Affairs/Princeton Univ.) now offers general readers not just the findings of psychological research but also a better understanding of how research questions arise and how scholars systematically frame and answer them. He begins with the distinction between System 1 and System 2 mental operations, the former referring to quick, automatic thought, the latter to more effortful, overt thinking. We rely heavily, writes, on System 1, resorting to the higher-energy System 2 only when we need or want to. Kahneman continually refers to System 2 as “lazy”: We don’t want to think rigorously about something. The author then explores the nuances of our two-system minds, showing how they perform in various situations. Psychological experiments have repeatedly revealed that our intuitions are generally wrong, that our assessments are based on biases and that our System 1 hates doubt and despises ambiguity. Kahneman largely avoids jargon; when he does use some (“heuristics,” for example), he argues that such terms really ought to join our everyday vocabulary. He reviews many fundamental concepts in psychology and statistics (regression to the mean, the narrative fallacy, the optimistic bias), showing how they relate to his overall concerns about how we think and why we make the decisions that we do. Some of the later chapters (dealing with risk-taking and statistics and probabilities) are denser than others (some readers may resent such demands on System 2!), but the passages that deal with the economic and political implications of the research are gripping.

BOOK REVIEW
IN THE NEWS
A readable, persuasive argument that our ways of doing business will have to change if we are to prosper—or even survive.
A well-constructed critique of an economic system that, by the author’s account, is a driver of the world’s destruction.
Harvard Business School professor Henderson vigorously questions the bromide that “management’s only duty is to maximize shareholder value,” a notion advanced by Milton Friedman and accepted uncritically in business schools ever since. By that logic, writes the author, there is no reason why corporations should not fish out the oceans, raise drug prices, militate against public education (since it costs tax money), and otherwise behave ruinously and anti-socially. Many do, even though an alternative theory of business organization argues that corporations and society should enjoy a symbiotic relationship of mutual benefit, which includes corporate investment in what economists call public goods. Given that the history of humankind is “the story of our increasing ability to cooperate at larger and larger scales,” one would hope that in the face of environmental degradation and other threats, we might adopt the symbiotic model rather than the winner-take-all one. Problems abound, of course, including that of the “free rider,” the corporation that takes the benefits from collaborative agreements but does none of the work. Henderson examines case studies such as a large food company that emphasized environmentally responsible production and in turn built “purpose-led, sustainable living brands” and otherwise led the way in increasing shareholder value by reducing risk while building demand. The author argues that the “short-termism” that dominates corporate thinking needs to be adjusted to a longer view even though the larger problem might be better characterized as “failure of information.” Henderson closes with a set of prescriptions for bringing a more equitable economics to the personal level, one that, among other things, asks us to step outside routine—eat less meat, drive less—and become active in forcing corporations (and politicians) to be better citizens.
