The Royal Swedish Academy of Sciences will announce the Nobel Prize winner in economics – technically, the Bank of Sweden Prize in Economic Sciences in Memory of Alfred Nobel – today. The Guardian has a list of probable winners – Olivier Blanchard of MIT, Edward Lazear of Stanford’s Hoover Institution, Marc Melitz of Harvard and Paul Romer of NYU Stern. It’s tough to say if one or more of these economists will win. But, it should come as no surprise that each one of them is associated with an American university. American economists tend to dominate the list (see chart below). There might even be a bias towards free market economics, according to a book The Nobel Factor: The Prize in Economics, Social Democracy, and the Market Turn by economic historians Avner Offer and Gabriel Söderberg.
