    But the failure rate of new businesses is disappointingly high, and the economic impact of most of them disappointingly low, suggesting that enthusiastic would-be entrepreneurs and their investors all too often operate under a false set of assumptions. This book shows that the reality of entrepreneurship is decidedly different from the myths that have come to surround it. Scott Shane, a leading expert in entrepreneurial activity in the United States and other countries, draws on the data from extensive research to provide accurate, useful information about who becomes an entrepreneur and why, how businesses are started, which factors lead to success, and which predict a likely failure. The Illusions of Entrepreneurship is an essential resource for everyone who has dreamed of starting a new business, for investors in start-ups, for policy makers attempting to facilitate the formation and survival of new businesses, and for researchers interested in the economic impact of entrepreneurial activity. Scott Shane offers research-based answers to these questions and many others:·        Why do people start businesses?·        What industries are popular for start-ups?·        How many jobs do new businesses create?·        How do entrepreneurs finance their start-ups?·        What makes some locations and some countries more entrepreneurial than others?·        What are the characteristics of the typical entrepreneur?·        How well does the typical start-up perform?·        What strategies contribute to the survival and profitability of new businesses over time?

    Whatever you or I do personally--eat tofu in a Hummer or hamburgers in a Prius--the planet doesn't notice. In our confrontation with climate change, species preservation, and a planet going off the cliff, it is what several billion people do that makes a difference. The solution? It isn't science, politics, or activism. It's smarter economics.The hope of mankind, and indeed of every living thing on the planet, is now in the hands of the dismal science. Fortunately, we've been there before. Economists helped crack the acid rain problem in the 1990's (admittedly with a strong assist from a phalanx of lawyers and activists). Economists have helped get lead out of our gas, and they can explain why lobsters haven't disappeared off the coast of New England but tuna is on the verge of extinction. More disquietingly, they can take the lessons of the financial crisis and model with greater accuracy than anyone else the likelihood of environmental catastrophe, and they can help save us from global warming, if only we let them.
