In 2001 Masahisa Fujita, Paul Krugman and Anthony Venables published “The Spatial Economy. Cities, Regions and International Trade”; the book is on sale, and you can access the intro chapter on Paul Krugman’s website. As those following this blog know, I am no economist, but I am interested on how such economy influences cities; some of the issues raised in the book refer to economic theories that I simply do not know, or that I could not judge by lack of knowledge, or event some that could raise my skepticism, not so much about their intellectual construction as about their practical utility. Despite that, I find interesting the way in which the evolution of the discipline is described, as leaning progressively, at least for some, rather towards what can be modeled into equations and not the whole picture.
