The benefit of appointing a hawkish central banker is the increased inflation-fighting credibility that such an appointment brings.

The economist John Maynard Keynes said that in the long run, we are all dead. If he were around today he might say that, in the long run, we are all on Social Security and Medicare.

I'd throw dollars out of helicopters if I had to, to stimulate the economy.

It takes about two and a half percent growth just to keep unemployment stable.

Weaker currencies abroad mean a strong dollar, and a stronger dollar, together with a weak global environment, is a drag on the U.S. economy. So it's important, as it affects overall levels of production and employment in the U.S. There are many domestic industries doing well in the United States, notwithstanding a strong dollar.

There's no denying that a collapse in stock prices today would pose serious macroeconomic challenges for the United States. Consumer spending would slow, and the U.S. economy would become less of a magnet for foreign investors. Economic growth, which in any case has recently been at unsustainable levels, would decline somewhat. History proves, however, that a smart central bank can protect the economy and the financial sector from the nastier side effects of a stock market collapse.

If current trends continue, the typical U.S. worker will be considerably more productive several decades from now. Thus, one might argue that letting future generations bear the burden of population aging is appropriate, as they will likely be richer than we are even taking that burden into account.
