The nomination of Kevin Warsh to be the next chair of the Federal Reserve obviously has big implications for markets. But it also comes with some interesting sociological questions too. What role does the Fed chair actually play in setting monetary policy? How do they communicate -- and influence -- members of the Fed board? How do they communicate to markets? What happens when someone who's been advocating major regime change at the central bank is now running it? And how do they balance independence with politics? In this episode we speak with Richard Clarida, former Fed vice-chair and now global economic advisor to Pimco. We talk about what a Fed chair actually does and what we know about Warsh's policy stances so far, as well as why Clarida thinks there may be more volatility in the bond market as a result.
