We propose a New Keynesian model with the shadow rate, which is the federal funds rate during normal times. At the zero lower bound, we establish empirically the negative shadow rate summarizes unconventional monetary policy with its resemblance to private interest rates, the Fed's balance sheet, and Taylor rule. Theoretically, we formalize our shadow rate New Keynesian model with QE and lending facilities. 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.

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 two-country model to accommodate for unconventional monetary policy. In our model, these anomalies disappear. We allow unconventional policy to be partially active and asymmetric between the 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.

This book provides comprehensive coverage of Lithium (Li) metal anodes for rechargeable batteries. Li is an ideal anode material for rechargeable batteries due to its extremely high theoretical specific capacity (3860 mAh g-1), low density (0.59 g cm-3), and the lowest negative electrochemical potential (−3.040 V vs. standard hydrogen electrode). Unfortunately, uncontrollable dendritic Li growth and limited Coulombic efficiency during Li deposition/stripping inherent in these batteries have prevented their practical applications over the past 40 years. With the emergence of post Li-ion batteries, safe and efficient operation of Li metal anode has become an enabling technology which may determine the fate of several promising candidates for the next generation energy storage systems, including rechargeable Li-air batteries, Li-S batteries, and Li metal batteries which utilize intercalation compounds as cathodes. In this work, various factors that affect the morphology and Coulombic efficiency of Li anode are analyzed. The authors also present the technologies utilized to characterize the morphology of Li deposition and the results obtained by modeling of Li dendrite growth. Finally, recent developments, especially the new approaches that enable safe and efficient operation of Li metal anode at high current densities are reviewed. The urgent need and perspectives in this field are also discussed. The fundamental understanding and approaches presented in this work will be critical for the application of Li metal anodes. The general principles and approaches can also be used in other metal electrodes and general electrochemical deposition of metal films. Summarizes the opportunities and main challenges in the application of Li metal anodes in electrochemical devices Reveals the fundamental mechanism of metal dendrite growth during electrochemical processes Reviews the main approaches and techniques used to investigate Li metal deposition processes and Li film morphologies Suggests key areas for the further development of Li metal anodes Highlights how the general principles and approaches developed for repeated deposition/stripping of smooth Li metal films can be used in other metal electrode and general electrochemical deposition of metal films.

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.
