The state of the macro: new developments

Paul Krugman in his article has criticized the current macroeconomists for throwing out everything interesting from macro models by assuming away bubbles, irrationality, "animal spirit".  A recent conference "What's wrong with current macroeconomics" addressed some of Krugman's concerns. A couple of articles on www.voxeu.org popularize some of the research in that direction:

• "heuristic" economic agents (Top down versus bottom up macroeconomics by Paul de Grauwe) that do not quite understand how the economy works but by optimizing their behavior trying various simple rules
• incorporating politics, institutions, and ideology in their models (The roles of ideology, institutions, politics and economic knowledge in forecasting macroeconomic developments: Illustrations from the recent crisis by Alex Cukierman)
