|Global Effective Lower Bound and Unconventional Monetary Policy|
with Jing Cynthia Wu: w24714
In a standard open-economy New Keynesian model, the effective lower bound causes anomalies: output and terms of trade respond to a supply shock in the opposite direction compared to normal times. We introduce a tractable framework to accommodate for unconventional monetary policy. In our model, these anomalies disappear. We allow unconventional policy to be partially active and asymmetric between countries. Empirically, we find the US, Euro area, and UK have implemented a considerable amount of unconventional monetary policy: the US follows the historical Taylor rule, whereas the others have done less compared to normal times.

|November 2016||A Shadow Rate New Keynesian Model|
with Jing Cynthia Wu: w22856
We propose a tractable and coherent framework that captures both conventional and unconventional monetary policies with the shadow fed funds rate. Empirically, we document the shadow rate's resemblance to an overall financial conditions index, various private interest rates, the Fed's balance sheet, and the Taylor rule. Theoretically, we demonstrate the impact of unconventional policies, such as QE and lending facilities, on the economy is identical to that of a negative shadow rate, making the latter a useful summary statistic for these policies. Our model generates the data-consistent result: a negative supply shock is always contractionary. It also salvages the New Keynesian model from the zero lower bound induced structural break.
