Getting bang for your buck - Joseph Stiglitz

We are all Keynesians now. Even the right in the United States has joined the Keynesian camp with unbridled enthusiasm and on a scale that at one time would have been truly unimaginable.

For those of us who always claimed some connection to the Keynesian tradition, this is a moment of triumph, after having been left in the wilderness, almost shunned, for more than three decades. At one level, what is happening now is a triumph of reason and evidence over ideology and interests.

Economic theory has long explained why unfettered markets were not self-correcting, why regulation was needed, why there was an important role for government to play in the economy. But many, especially people working in the financial markets, pushed a type of "market fundamentalism". The misguided policies that resulted – pushed by, among others, some members of President-elect Barack Obama's economic team – had earlier inflicted enormous costs on developing countries. The moment of enlightenment came only when those policies also began inflicting costs on the US and other advanced industrial countries.
