WASHINGTON (AFX) - Stable prices of goods and services is the cornerstone of good economic performance, said new Fed chief Ben Bernanke on Friday. Returning to Princeton University for his first address, Bernanke trumpeted Wall Street's favorite topic: stable prices. 'When prices are stable, people can hold money for transactions and other purposes without having to worry that inflation will eat away at the real value of their money balances,' Bernanke said. 'Equally important, stable prices allow people to rely on the dollar as a measure of value when making long-term contracts, engaging in long-term planning or lending for long periods,' Bernanke said.
