The nature and scope of the Federal Reserve's authority and the structure of its decision making are now “on the table” to an extent that has not been seen since 1935, and the Fed's vaunted independence is under some attack. This essay asks what the Federal Reserve should—and shouldn't—do, leaning heavily on the concept of economies of scope. In particular, I conclude that the central bank should monitor and regulate systemic risk because preserving financial stability is (a) closely aligned with the standard objectives of monetary policy and (b) likely to require lender of last resort powers. I also conclude that the Fed should supervise large financial institutions because that function is so closely to regulating systemic risk. However, several other functions now performed by the Fed could easily be done elsewhere.

This paper provides an introduction and “user guide” to Regression Discontinuity (RD) designs for empirical researchers. It presents the basic theory behind the research design, details when RD is likely to be valid or invalid given economic incentives, explains why it is considered a “quasi-experimental” design, and summarizes different ways (with their advantages and disadvantages) of estimating RD designs and the limitations of interpreting these estimates. Concepts are discussed using examples drawn from the growing body of empirical research using RD.

This paper is a survey of the literature on boards of directors, with an emphasis on research done subsequent to the Benjamin E. Hermalin and Michael S. Weisbach (2003) survey. The two questions most asked about boards are what determines their makeup and what determines their actions? These questions are fundamentally intertwined, which complicates the study of boards because makeup and actions are jointly endogenous. A focus of this survey is how the literature, theoretical as well as empirical, deals—or on occasions fails to deal—with this complication. We suggest that many studies of boards can best be interpreted as joint statements about both the director-selection process and the effect of board composition on board actions and firm performance.
