As a result, he said, they had stunted development, while many other nations prospered. Professor Calestous Juma tells the story of dueling economic theories. One based on new ideas and risk taking, and the other on pessimism and ignorance. Its a story of the haves and have nots. Juma is professor of the Practice of International Development and Faculty Chair of the Innovation for Economic Development Executive Program. In 1911, an Austrian economist by the name of Joseph Schumpeter published a book called The Theory of Economic Development, which proposed that economies grow over time through innovation. Through new combinations that involved the application of new technologies. And this book became really a standard on how to think about economic transformation through the use of technology and entrepreneurship, he said. Juma said Schumpeter took a different view on what was needed for robust economic growth. It was new because up to that point people believed that economies grew because of extraction of natural resourcesnot because of application of technologies. It was also new because he proposed that the use of new technologies resulted in revolutionary changes in economic systems. |
