(Bloomberg) -- Ken Matheny, Executive Director of U.S. Economics at Macroeconomic Advisers by IHS Markit, says St. Louis Fed Bank President Bullard has had "quite a lot of influence" on Fed policy, bringing a diversity of thought that adds discipline to the central bank's policy discussions. In contrast to Bullard's current views, Matheny says the Federal Reserve will hike its key rate a total of four times this year as the labor market continues to tighten and fiscal stimulus gives a boost to growth.

Matheny speaks with Bloomberg Global Economics and Politics Editor Kathleen Hays at the Federal Reserve Bank of St. Louis in St. Louis, Missouri.
