Which is more dangerous, a gun or a swimming pool?
What do schoolteachers and sumo wrestlers have in common?
How much do parents really matter?
These may not sound like typical questions for an economist to ask. But Steven D. Levitt is not a typical economist. He studies the riddles of everyday life—from cheating and crime to parenting and sports—and reaches conclusions that turn conventional wisdom on its head.
Freakonomics is a groundbreaking collaboration between Levitt and Stephen J. Dubner, an award-winning author and journalist. They set out to explore the inner workings of a crack gang, the truth about real estate agents, the secrets of the Ku Klux Klan, and much more.
Through forceful storytelling and wry insight, they show that economics is, at root, the study of incentives—how people get what they want or need, especially when other people want or need the same thing.

In 1831 Alexis de Tocqueville, a young French aristocrat and ambitious civil servant, set out from post-revolutionary France on a journey across America that would take him 9 months and cover 7,000 miles. The result wasDemocracy in America, a subtle and prescient analysis of the life and institutions of 19th-century America. Tocqueville looked to the flourishing deomcratic system in America as a possible model for post-revolutionary France, believing that the egalitarian ideals it enshrined reflected the spirit of the age and even divine will. His study of the strengths and weaknesses of an evolving democratic society has been quoted by every American president since Eisenhower, and remains a key point of reference for any discussion of the American nation or the democratic system.
This new edition is the only one that contains all Tocqueville's writings on America, including the rarely-translated Two Weeks in the Wilderness, an account of Tocqueville's travels in Michigan among the Iroquois, and Excursion to Lake Oneida.

This brilliantly conceived and organized book is Dr. Leonard Peikoff’s classic text on the abstract principles and practical applications of Objectivism, based on his lecture series “The Philosophy of Objectivism.” Ayn Rand said of these lectures: “Until or unless I write a comprehensive treatise on my philosophy, Dr. Peikoff’s course is the only authorized presentation of the entire theoretical structure of Objectivism—that is, the only one that I know of my knowledge to be fully accurate.”
In Objectivism, Peikoff covers every philosophic topic that Rand regarded as important—from certainty to money, from logic to art, from measurement to sex. Drawn from Rand’s published works as well as in-depth conversations between her and Peikoff, these chapters illuminate Objectivism—and its creator—with startling clarity. With Objectivism, the millions of readers who have been transformed by Atlas Shrugged and The Fountainhead will discover the full philosophical system underlying Ayn Rand’s work.
