I, for one, am not so sure that winning the Nobel Prize in economics should be taken as prima facie evidence of sound overall economic analysis. Paul Krugman, Joseph Stiglitz, and Paul Samuelson all won Nobel Prizes and I find most of their economic analysis abysmal. Even the work of Milton Friedman, another Nobel Laurette greatly disappoints when it comes to economic method and monetary analysis.
It turns out that a main reason to maintain a healthy skepticism about the pronouncements of Nobel Prize winners is that the committee awarding the prize has demonstrated decidedly destructive biases in their awards. That is the conclusion of economist Nikolay Gertchev, a PhD economist now working for the European Commission in Brussels. In his article "The Economic Nobel Prize," Gertchev first documents the bias toward mathematical economics and the relativism that results from empirical positivism.
About research programs of Prize recipients, he notes
The vast majority of rewarded contributions, while pertaining to different fields ofscientific investigation, and hence raising different questions, share in common two basic views, which will be addressed separately in the next two sub-sections. According to the first view, the market process is inefficient. According to the second view, the failures of this inefficient market process need to be corrected, and government policies are potent and well suited for achieving this goal.
The most fundamental problem that such a pro-government and anti-market bias is causing for a Prize that claims to be scientific is its relation to truth. The single goal of scientific research should be the discovery of new knowledge, either through correcting past errors or through the discovery of previously unknown truths. Truth, however, does not appear to be a primary concern for the Prize committee in economics.

Given such a track record, perhaps not only is it not enough for a Fed Governor to be a Nobel Prize winner. Perhaps it is undesirable.
