I had never heard of Netlogo, which is a programming language for simulating and teaching agent based models. Agent-based modeling is important because it might be the key to real quantitative simulation in economics and the social sciences.

Lords of Finance: The Bankers Who Broke the World
This book was kind of a hard read, but I’m glad I read it. My favorite part of the book was the last five pages, particularly these quotes explaining just how bad the Depression really was.
Anyone who writes or thinks about the Great Depression cannot avoid the question: Could it happen again? First it is important to remember the scale of the economic meltdown that occurred in 1929 to 1933. During a three-year period, real GDP in the major economies fell by over 25 percent, a quarter of the adult male population was thrown out of work, commodity prices fell in half, consumer prices declined by 30 percent, wages were cut by a third. Bank credit in the United States shrank by 40 percent and in many countries the whole banking system collapsed. Almost every major sovereign debtor among developing countries and in Central and Eastern Europe defaulted, including Germany, the third largest economy in the world. The economic turmoil created hardships in every corner of the globe, from the prairies of Canada to the teeming cities of Asia, from the industrial heartland of America to the smallest village in India. No other period of peace time economic turmoil since has even come close to approaching the depth and breadth of that cataclysm…
[The Great Depression was] a crisis equivalent in scope to the combined effects and more of the 1994 Mexican peso crises, the 1997-98 Asian and Russian crises, the 2000 collapse in the stock market bubble, and the 2007/8 world financial crisis, all cascading upon one and other in a single concentrated two-year period. The world has been saved in part from anything approaching the Great Depression because the crises that have buffeted the world economy over the past decade [writing in 2009] have conveniently struck one by one, with decent intervals in between.
21st Century Cosmopolis
This guy, Steven Colatrella, has drafted a new constitution for the world that abolishes nation-states in favor of city-states. It also abolishes debt, credit, wages, and big business. In short, it sounds like a return to the original concepts of idealized socialism or communism. I don’t know about all that, but there might be a few ideas worth pulling out. I do like the idea of treating metropolitan areas as our society’s core economic and social units – clearly that is what they already are, and our political system is not consistent with that. Another idea that is somewhat interesting is that each city has its local currency, with a universal currency available but used only in transactions between cities.
