1. In one of my IHS seminar talks, I made a brief reference to Karl Marx. Here's more courtesy of Walter Williams and takes by Tyler Cowen and Brad DeLong.

2. I've just come across the World Bank's Private Sector Development blog--it has gobs of material similar to my institutions and growth talk. And, as I mentioned near the end of my talk, Economic Freedom of the World project (run by my co-blogger Bob Lawson and his mentor Jim Gwartney) is another great source of info on institutions.

3. After one of my talks there was a question about population growth and scarce resources. Julian Simon addresses those issues in The Ultimate Resource II.

ADDENDUM: Two more follow up items.

1. Here's an article on India's growth over the past 15 years.

2. One of the questions posed after my third lecture was about how one might measure corruption. The International Country Risk Guide publishes a measure of corruption (here but it requires payment); I think it is based on surveys of people living or doing business in each country. Co-blogger Craig Depken has a couple of papers here and here on the effects of corruption on credit markets.
