The markets are hanging fire waiting for Federal Reserve Chairman Janet Yellen's annual speech at the Jackson Hole, Wyoming. conference Friday. First question, of course, is what will happen to the federal funds rate and how that will affect interest rates and, potentially, deals. Economist David Levy talks about those matters, as well as the Fed's focus on the labor market.

But cheap debt for some time to come will still be likely to fuel deals.
