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.

These are not hard and fast rules, but Meyer delivers important reading for those engaged in international business.
A helpful guide to working effectively with people from other cultures.
“The sad truth is that the vast majority of managers who conduct business internationally have little understanding about how culture is impacting their work,” writes Meyer, a professor at INSEAD, an international business school. Yet they face a wider array of work styles than ever before in dealing with clients, suppliers and colleagues from around the world. When is it best to speak or stay quiet? What is the role of the leader in the room? When working with foreign business people, failing to take cultural differences into account can lead to frustration, misunderstanding or worse. Based on research and her experiences teaching cross-cultural behaviors to executive students, the author examines a handful of key areas. Among others, they include communicating (Anglo-Saxons are explicit; Asians communicate implicitly, requiring listeners to read between the lines), developing a sense of trust (Brazilians do it over long lunches), and decision-making (Germans rely on consensus, Americans on one decider). In each area, the author provides a “culture map scale” that positions behaviors in more than 20 countries along a continuum, allowing readers to anticipate the preferences of individuals from a particular country: Do they like direct or indirect negative feedback? Are they rigid or flexible regarding deadlines? Do they favor verbal or written commitments? And so on. Meyer discusses managers who have faced perplexing situations, such as knowledgeable team members who fail to speak up in meetings or Indians who offer a puzzling half-shake, half-nod of the head. Cultural differences—not personality quirks—are the motivating factors behind many behavioral styles. Depending on our cultures, we understand the world in a particular way, find certain arguments persuasive or lacking merit, and consider some ways of making decisions or measuring time natural and others quite strange.
