The repost of a Peter Dorman's post with comments by Mark Thoma "Mankiw’s Reply to the Walk-Out". Peter Dorman says
"That’s a bias. ... There is a reason why exposure to economics, and especially the worldview-defining core of microeconomics, tends to shift student views, on average, in a libertarian direction."
with a link to the 1993 article Does Studying Economice Inhibit Cooperation?
Marion Foucarde in The construction of a Global Profession: The Transnationalization of Economics(2006) points to the influence of US trained economists in various developing countries.
A recent post by Jeff Frankel The Hour of Technocrats mentions "Among current heads of state who could be considered technocrats are President Felipe Calderónof Mexico, President Sebastián Piñeraof Chile, and President Ellen Johnson Sirleafof Liberia. Nobody could accuse these three of having led sheltered lives or being unaccustomed to making difficult decisions. But it happens that all three received their ivory tower training at the Harvard."
It seems that what is taught in Harvard concerns all of us.
