This is a book that should be read by all economists." -- Roger E. Backhouse, "The Economic Journal" "A stimulating essay by one of the world's most thoughtful and innovative economists.
Paul Robin Krugman is an American economist, liberal columnist and author. He is Professor of Economics and International Affairs at the Woodrow Wilson School of Public and International Affairs, Princeton University, Centenary Professor at the London School of Economics, and an op-ed columnist for The New York Times. In 2008, Krugman won the Nobel Memorial Prize in Economics for his contributions to New Trade Theory and New Economic Geography.
As I student of geography it's great to hear a Nobel laureate go record that economists are missing out by leaving considerations of space out of their analyses.
The idea that main economic insights in the past failed to impact mainstream economics due to our inability to formalize them in models is interesting. Krugman, basically, defends the need for formal models and accepts that insights and models will follow an ebb and flow pattern. I particularly enjoyed the last chapter about models, and their costs and benefits. That chapter alone is worth the read.
By the way, many of the ideas are similar to the ones developed in Krugman’s other (little) book on Geography and Trade.
Un gran Libro para aquellos interesados en la tradición económica relacionada al Desarrollo Económico y la Economía Geográfica, gran perspectiva respecto al pasado y presente de ambas disciplinas y sobre sus alternativas, de la misma forma contiene una gran explicación sobre el "arte" de crear modelos y como estos constituyen metáforas sobre la realidad, por ultimo contiene una muy buena explicación respecto ala construcción de los modelos de aglomeración de Krugman (1991)-(1993) desde su empleo de competencia imperfecta a la Dixit-Stiglitz hasta su incorporación de fuerzas centrifugas y centripetas y las enseñanzas que dicho modelo nos deja.
