Federal Reserve policies can benefit U.S. labor markets but cannot alone solve the so-called skills mismatch between workers and employers, New York Fed President William Dudley said on Wednesday. Dudley, in prepared remarks, stressed the need for companies to invest in workforce development to better prepare employees for new technologies on factory floors and other workplaces. The Fed has kept interest rates near zero for six and a half years to boost employment and help the economy recover from recession.
