In Congressional testimony, former Federal Reserve Chairman Ben Bernanke said: Another significant factor influencing ­medium- term trends in inflation is the public's expectations of inflation. These expectations have an important bearing on whether transi-tory influences on prices, such as changes in energy costs, become embedded in wage and price decisions and so leave a lasting imprint on the rate of inflation. What did Bernanke mean when he said that the public's expectations of inflation could " become embedded in wage and price decisions"? What would be the effect on the short- run Phillips curve of the public coming to expect a higher inflation rate?
