Regime Uncertainty?

Robert Higgs has argued that one of the factors contributing to the weak economy in the 1930s was regime uncertainty. It seems plausible that this may also be contributing to a slower-than-otherwise economy at the present time. But is there any evidence for it?

what kind of evidence are you hoping for?

Higgs talks about it in today’s environment here here and here . Here he is on it and the current oil spill. Here is another post that talks about it in today’s environment as well.
