By John S. McClenahen While many executives continue to worry about 2000's final-quarter inventory overhang, short-term profits, and short-term interest rates (Will there be another 50-basis point cut on or before Mar. 20?), Federal Reserve Chairman Alan Greenspan is impressed that "most corporate managers" remain keen on technology. He related to the U.S. Senate Banking committee this week, for example, the results of a recent survey showing that the wave of online B2B continues to rise. "Corporate managers, more generally, rightly or wrongly, appear to remain remarkably sanguine about the potential for inventions to continue to enhance productivity and profits," he stated, in vintage Greenspanese.
