Economics of Contempt lists a couple dozen leading economic pundits that who actively denied the existence of a housing bubble, the very bubble that has us in a major economic mess now.
Dean Baker and Paul Krugman got it right. But, notably, the list of those who got it very wrong, not long before the bubble burst, is heavily populated with politically conservative economists (support for the proposition that they got it wrong is in the link above).

The list also notably illustrates another important point. A plausible, even compelling economic argument, and the confidence of the people who put you in a good position to expound upon your economic arguments, does not mean that you are right.
In the hard sciences, the guys with the most expertise are right a very large percentage of the time. In economics, this isn't true.
