The book is based on my dissertation. All previous cross-country indices of entrepreneurship to my knowledge have relied on self-employment or measures very similar to self-employment (such as business startups, which is entry into self-employment).
The problem with this is that self-employment is quite different from innovative, high growth entrepreneurship. Policy makers are often more interested in the latter; in having more firms like Google, Microsoft, Wal-Mart and Apple, not more taxi drivers and dentists.
The policies and the institutional environment that fosters innovative entrepreneurship turn out to be quite different from the institutions and policies that drive small-scale self employment. High taxes for example inhibit innovative entrepreneurship, but might even encourage self-employment, since the self-employed can more easily evade taxes.
Similarly, stricter regulations on startups, is associated with more firms. The countries with the highest self-employment rate in the OECD are Greece, Italy, Mexico, South Korea, Turkey and Portugal, all regulated, with low-quality institutions relative the rest of the developed world, and lower per capita income. I argue that this paradoxical result is in part caused by evasion of regulations and in part by dampened competition. In countries with more regulations and worse institutions, it is harder for the best firms to grow rapidly and to absorb and outcompete the least effective firms.
The United States is the world’s most entrepreneurial major economy, with 31 percent of the largest 100 public firms having been created in recent history by entrepreneurs, compared to merely 7 percent in Western Europe. At the same time, the United States has the second lowest self-employment rate among developed countries. Western Europe has twice the self-employment rate of the United States. Similarly the self-employment rate in Silicon Valley is lower than the U.S national average and half that of California.
This book creates the first international index of high-impact entrepreneurship by compiling a comprehensive list of self-made billionaire entrepreneurs during the last two decades, relying on Forbes Magazine's list of billionaires. In this way the world's 1000 or so most successful entrepreneurs are identified in 53 different countries. Entrepreneurship is the most common source of great wealth.
It turns out that 58% of the world’s richest individuals and 65% of America’s richest individuals are self-made entrepreneurs. My idea in picking these measures was simple - since we care about Google, Microsoft, Wal-Mart and Apple whenever we talk about entrepreneurship, and use these firms as archetypes and examples, why not create an empirical measure which corresponds as much as possible with such firms and their creators. Billionaire Entrepreneurs are more common than people realize, which made it possible to create a cross-country index.
In the book we find that institutional quality, property rights protection, tax rates, regulations on startups, financial sophistication and human capital are the most important factors associated with having a high number of SuperEntrepreneurs in your country. We also show that these measures typically are related in an opposite way to self-employment, which may explain why previous studies have struggled with identifying the determinant of entrepreneurship. By contrast many common policies aimed at promoting small business and self-employment seem to have no effect, perhaps in part because small business and self-employment are so different from innovative entrepreneurship.
I discuss this in a paper with Peter Leeson. While weak property rights protection is associated with having fewer billionare entreprenurs, it is associated with having more self-employment.


The book further describes the stories of many of the less well-known SuperEntrepreneurs and their firms. Entrepreneurship is a complex phenomenon, and is better understood and its importance for the economy easier shown when illustrated through examples.
Examples of American firms that appears in our indices of entrepreneurial firms are Intel, Microsoft, Google, Apple, Yahoo, Oracle, Cisco, Sun Microsystems, Bloomberg, PayPal, AOL, Facebook, E-bay, Dell, Hewlett-Packard, Gateway, inc, Priceline.com, Amazon, Wal-Mart, Home Depot, Best Buy, Family-Dollar stores, The GAP, Urban Outfitters, Ralph Lauren, Nike, Trader Joe's, Starbucks, Subway, Blackstone, Bridgewater, KKR, CNN, Fox News, Univision, HBO, The Weather Channel, Black Entertainment Television, DreamWorks, Lucas Arts, Ultimate Fighting Championship, Ty Inc.

Other examples are Japanese Sony, Honda and Softbank, Canadians Research in Motion (Blackberry) and Cirque du Soleil, Israeli Check Point Software and Hong Kong's Cathay Pacific Airways.
Now you know what I am doing and why I am not writing much on the blog until the book is done.
