Summary

Matt Ridley, author of The Rational Optimist, talks with EconTalk host Russ Roberts about why he is optimistic about the future and how trade and specialization explain the evolution of human development over the millennia. Ridley argues that life is getting better for most of the people on earth and that the underlying cause is trade and specialization. He discusses the differences between Smith's and Ricardo's insights into trade and growth and why despite what seems to be strong evidence, people are frequently pessimistic about the future. Ridley also addresses environmental issues.

1:01.7	You try to do something that is just a little bit beyond modest.
1:07.9	You try to explain all of human history around a small, a small slice of
1:15.3	what we might want to know about, and you provocatively leverage the idea that trade,
1:23.6	the ability to exchange and the subsequent division of labor that ensues can explain much of human
1:30.7	development going back really thousands of years yes one of my ambitions is to try and take the
1:39.4	notion of trade a lot further back into prehistory than people generally do there's been a tendency
1:43.9	among anthropologists and archaeologists to say that look you can't a lot further back into prehistory than people generally do. There's been a tendency among
1:44.4	anthropologists and archaeologists to say that, look, you can't do trade until you've invented
1:49.6	law and order and government and farming and things like that. And I think the evidence suggests
1:55.3	that simply isn't true that Hunter-gatherers are perfectly good at trading and that it had a crucial
2:00.4	impact on human history.
2:03.2	But my other ambition is to say, look, this is actually the grand theme of human history.
