A very good article from the Economist - "A special report on entrepreneurship: An idea whose time has come" here. The report connects entrepreneurship and economics:
"Today entrepreneurship is very much part of economics. Economists have realised that, in a knowledge-based economy, entrepreneurs play a central role in creating new companies, commercialising new ideas and, just as importantly, engaging in sustained experiments in what works and what does not. William Baumol has put entrepreneurs at the centre of his theory of growth. Paul Romer, of Stanford University, argues that “economic growth occurs whenever people take resources and rearrange them in ways that are more valuable…[It] springs from better recipes, not just more cooking.” Edmund Phelps, a Nobel prize-winner, argues that attitudes to entrepreneurship have a big impact on economic growth."
The report believes that entrepreneurship going mainstream also lies in "... that the social contract between big companies and their employees has been broken."
The report discusses a fantastic effort by the World Bank:
"In 2003 the World Bank began to publish an annual report called Doing Business, rating countries for their business-friendliness by measuring things like business regulations, property rights and access to credit. It demonstrated with a wealth of data that economic prosperity is closely correlated with a pro-business environment. This might sound obvious. But Doing Business did two things that were not quite so obvious: it put precise numbers on things that people had known about only vaguely, and it allowed citizens and investors to compare their country with 180 others."
