A Brief History of Economic Time

From Steve Landsburg:

".. just a couple of hundred years ago, maybe 10 generations -- people started getting richer. And richer and richer still. Per capita income, at least in the West, began to grow at the unprecedented rate of about three quarters of a percent per year. A couple of decades later, the same thing was happening around the world."

"...The source of this wealth -- the engine of prosperity -- is technological progress. And the engine of technological progress is ideas -- not just the ideas from engineering laboratories, but also ideas like new methods of crop rotation, or just-in-time inventory management. You can fly from New York to Tokyo partly because someone figured out how to build an airplane and partly because someone figured out how to insure it. I'm writing this on a personal computer instead of an electric typewriter partly because someone said, "Hey! I wonder if we can make computer chips out of silicon!" and partly because someone said "Hey! I wonder if we can finance startups with junk bonds!" ...

"...Engineers figure out how to harness the power of technology; economists figure out how to harness the power of incentives. Our prosperity relies on both."
