Janet Yellen's premier before Congress

On Tuesday Janet Yellen - the new chairman of the US Federal Reserve - answered questions in Congress about the direction in which she intends to steer monetary policy. Her session in Congress lasted more than six hours. "Unflappable" was one word used to describe her performance, "boring" was another. Stock markets were wowed by it - they like this kind of thing - share prices on Wall Street climbed. If this was a theatre production there'd be on of those posters saying "terrific, a five star tour de force by Ms Yellen....this one will run and run...."

In Phoenix Arizona, the economist Irwin Stelzer was listening - to some of it - what did he make of it?
