We present a new automated, objective and intuitive scoring technique to measure the content of central bank communication about future interest rate decisions based on information from the Internet and news sources. We apply the methodology to statements released by the Federal Open Market...

We find new facts that relate the evolution of firm scope to the changing frictions in external capital markets over the last three decades. We find that large, diversified publicly traded firms increase their scope during times of high external capital market frictions, such as in the recent...
