Is Japan the Canary in the Keynesian Coal Mine?

"(...) I have been following the events in Japan with great interest. This is partly out of the desire to understand how a large, modern economy can be moribund for 23 years and counting. But I’m also interested because the policies that Japan has utilized for so long are now being emulated by many countries around the world. Japanese policy is the avant-garde of economics — or, perhaps, the canary in the coal mine. And since the financial crisis of 2008, the United States and Europe are following a very similar path. Of course, every country has unique characteristics and is comprised of its own social customs, values, demographics, and history. However, the approach these countries are using — and which Japan is using with gusto — can generally be traced back to the same philosophical source: John Maynard Keynes. Moreover, because Japan has been using these policies and approaches for so long — and because it has a very insular culture — we have a rich laboratory with which to make observations about the efficacy of monetary policy, fiscal stimulus, debt issuance, monetization of debt, and so forth."
