    In Standard Deviations, economics professor Gary Smith walks us through the various tricks and traps that people use to back up their own crackpot theories. Sometimes, the unscrupulous deliberately try to mislead us. Other times, the well-intentioned are blissfully unaware of the mischief they are committing. Today, data is so plentiful that researchers spend precious little time distinguishing between good, meaningful indicators and total rubbish. Not only do others use data to fool us, we fool ourselves.With the breakout success of Nate Silver’s The Signal and the Noise, the once humdrum subject of statistics has never been hotter. Drawing on breakthrough research in behavioral economics by luminaries like Daniel Kahneman and Dan Ariely and taking to task some of the conclusions of Freakonomics author Steven D. Levitt, Standard Deviations demystifies the science behind statistics and makes it easy to spot the fraud all around.

    But none has revealed just how significant a role it plays in the global economy--until now.A groundbreaking book sure to leave its mark in the canon of investing literature, The Rise of Carry explains how carry trading has virtually shaped the global economic picture--one of decaying economic growth, recurring crises, wealth disparity, and, in too many places, social and political upheaval. The authors explain how carry trades work--particularly in the currency and stock markets--and provide a compelling case for how carry trades have come to dominate the entire global business cycle. They provide thorough analyses of critical but often overlooked topics and issues, including:-The active role stock prices play in causing recessions--as opposed to the common belief that recessions cause price crashes-The real driving force behind financial asset prices-The ways that carry, volatility selling, leverage, liquidity, and profitability affect the business cycle-How positive returns to carry over time are related to market volatility--and how central bank policies have supercharged these returnsSimply put, carry trading is now the primary determinant of the global business cycle--a pattern of long, steady but unspectacular expansions punctuated by catastrophic crises.The Rise of Carry provides foundational knowledge and expert insights you need to protect yourself from what have come to be common market upheavals--as well as the next major crisis.

    Here reside some of South Africa’s wealthiest individuals: all male, all Afrikaans – and all stinking rich. Johann Rupert, Jannie Mouton, Markus Jooste and Christo Weise, to name a few.Julius Malema refers to them scathingly as ‘The Stellenbosch Mafia’, the very worst example of white monopoly capital. But who really are these mega-wealthy individuals, and what influence do they exert not only on Stellenbosch but more broadly on South African society?Author Pieter du Toit begins by exploring the roots of Stellenbosch, one of the wealthiest towns in South Africa and arguably the cradle of Afrikanerdom. This is the birthplace of apartheid leaders, intellectuals, newspaper empires and more.He then closely examines this ‘club’ of billionaires. Who are they and, crucially, how are they connected? What network of boardroom membership, alliances and family connections exist? Who are the ‘old guard’ and who are the ‘inkommers’, and what about the youngsters desperate to make their mark? He looks at the collapse of Steinhoff: what went wrong, and whether there are other companies at risk of a similar fate. He examines the control these men have over cultural life, including pulling the strings in South Africa rugby.

    The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by issues of aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science, creating a new understanding of energy use and metabolism: West found that despite the riotous diversity in the sizes of mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. This speaks to everything from how long we can expect to live to how many hours of sleep we need. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism's body. West's work has been game-changing for biologists, but then he made the even bolder move of exploring his work's applicability to cities. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. For every doubling in a city's size, the city needs 15% less road, electrical wire, and gas stations to support the same population. More amazingly, for every doubling in size, cities produce 15% more patents and more wealth, as well as 15% more crime and disease. This broad pattern lays the groundwork for a new science of cities. Recently, West has applied his revolutionary work on cities and biological life to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune, however diverse and unrelated they are to each other.From the Hardcover edition.

     Two hot topics team up in The Baseball Economist, and the result is a refreshing, clear- eyed survey of a playing field that has changed radically in recent years. Utilizing the latest economic methods and statistical analysis, writer, economics professor, and popular blogger J. C. Bradbury dissects burning baseball topics with his original Sabernomic perspective, such as: • Did steroids have nothing to do with the recent home run records? Incredibly, Bradbury's research, reviewed by Stanford economists, reveals steroids had little statistical significance. • Is the big-city versus small-city competition really lopsided? Bradbury shows why the Marlins and Indians are likely to dominate big-city franchises in the coming years. • Which players are ridiculously overvalued? Bradbury lists all players by team with their revenue value to the team listed in dollars—including a dishonor role of those players with negative values. • Is major league baseball a monopoly that can't govern itself? Bradbury sets out what rules the owners really need to play by, and what the players' union should be doing. • Does it help to lobby for balls and strikes? How would Babe Ruth perform in today's game? And who killed all the left-handed catchers, anyway? The Baseball Economist knows. Providing far more than a mere collection of numbers, Bradbury shines the light of his economic thinking on baseball, exposing the power of tradeoffs, competition, and incentives. Statistics alone aren't enough anymore. Fans, fantasy buffs, and players, as well as coaches at all levels who want to grasp what is really happening on the field today and in the coming years, will use and enjoy Bradbury's brilliant new understanding of the national pastime.

    But how can we avoid those all-too-familiar wails of “That’s not fair!” and “You can’t make me!”? In The Game Theorist’s Guide to Parenting, the award-winning journalist and father of five Paul Raeburn and the game theorist Kevin Zollman pair up to highlight tactics from the worlds of economics and business that can help parents break the endless cycle of quarrels and ineffective solutions. Raeburn and Zollman show that some of the same strategies successfully applied to big business deals and politics—such as the Prisoner’s Dilemma and the Ultimatum Game—can be used to solve such titanic, age-old parenting problems as dividing up toys, keeping the peace on long car rides, and sticking to homework routines.Raeburn and Zollman open each chapter with a common parenting dilemma. Then they show how carefully concocted schemes involving bargains and fair incentives can save the day. Through smart case studies of game theory in action, Raeburn and Zollman reveal how parents and children devise strategies, where those strategies go wrong, and what we can do to help raise happy and savvy kids while keeping the rest of the family happy too.Delightfully witty, refreshingly irreverent, and just a bit Machiavellian, The Game Theorist’s Guide to Parenting looks past the fads to offer advice you can put into action today.

    If you’ve ever sought a job or hired someone, applied to college or guided your child into a good kindergarten, asked someone out on a date or been asked out, you’ve participated in a kind of market. Most of the study of economics deals with commodity markets, where the price of a good connects sellers and buyers. But what about other kinds of “goods,” like a spot in the Yale freshman class or a position at Google? This is the territory of matching markets, where “sellers” and “buyers” must choose each other, and price isn’t the only factor determining who gets what.Alvin E. Roth is one of the world’s leading experts on matching markets. He has even designed several of them, including the exchange that places medical students in residencies and the system that increases the number of kidney transplants by better matching donors to patients. In Who Gets What — And Why, Roth reveals the matching markets hidden around us and shows how to recognize a good match and make smarter, more confident decisions.

    We now have occasion to ask, "What makes these institutions work? How important are they? How can we improve them?"Taking us on a lively tour of a world we once took for granted, John McMillan offers examples ranging from a camel trading fair in India to the $20 million per day Aalsmeer flower market in the Netherlands to the global trade in AIDS drugs. Eschewing ideology, he shows us that markets are neither magical nor immoral. Rather, they are powerful if imperfect tools, the best we've found for improving our living standards.A New York Times Notable Book.
