Monetary Policy Strategies for a Low-Rate Environment
In low-rate environments, policy strategies that involve holding rates ?lower for longer? (L4L) may mitigate the effects of the effective lower bound (ELB). However, these strategies work in part by managing the public?s expectations, which is not always realistic. Using the Fed?s large-scale macroeconometric model, we study the effectiveness of L4L policies when financial market participants are forward-looking but other agents are not. We find that the resulting limited ability to manage expectations reduces but does not eliminate the advantages of L4L policies. The best policies provide ...

Monetary Policy in a Low Interest Rate World
Nominal interest rates may remain substantially below the averages of the last half-century, as central bank?s inflation objectives lie below the average level of inflation and estimates of the real interest rate likely to prevail over the long run fall notably short of the average real interest rate experienced over this period. Persistently low nominal interest rates may lead to more frequent and costly episodes at the effective lower bound (ELB) on nominal interest rates. We revisit the frequency and potential costs of such episodes in a low-interest-rate world in a ...

Factor Selection and Structural Breaks
We develop a new approach to select risk factors in an asset pricing model that allows the set to change at multiple unknown break dates. Using the six factors displayed in Table 1 since 1963, we document a marked shift towards parsimonious models in the last two decades. Prior to 2005, five or six factors are selected, but just two are selected thereafter. This finding offers a simple implication for the factor zoo literature: ignoring breaks detects additional factors that are no longer relevant. Moreover, all omitted factors are priced by the selected factors in every regime. Finally, ...
