Central Bank Governance and Oversight Reform [PDF ebook] 

A central bank needs authority and a sphere of independent action. But a central bank cannot become an unelected czar with sweeping, unaccountable discretionary power. How can we balance the central bank’s authority and independence with needed accountability and constraints? Drawn from a 2015 Hoover Institution conference, this book features distinguished scholars and policy makers‘ discussing this and other key questions about the Fed.
