|May 2020||Bank Market Power and Monetary Policy Transmission: Evidence from a Structural Estimation|
with , , : w27258
We quantify the impact of bank market power on monetary policy transmission through banks to borrowers. We estimate a dynamic banking model in which monetary policy affects imperfectly competitive banks’ funding costs. Banks optimize the pass-through of these costs to borrowers and depositors, while facing capital and reserve regulation. We find that bank market power explains much of the transmission of monetary policy to borrowers, with an effect comparable to that of bank capital regulation. When the federal funds rate falls below 0.9%, market power interacts with bank capital regulation to produce a reversal of the effect of monetary policy.
|December 2018||Monetary Policy and Reaching for Income|
with , : w25344
We study the impact of monetary policy on investors' portfolio choices and asset prices. Using data on individual portfolio holdings and on mutual fund flows, we find that a low-interest-rate monetary policy increases investors' demand for high-dividend stocks and drives up their prices. The increase in demand is more pronounced among investors who fund consumption using dividend income. To explain these empirical findings, we develop an asset pricing model in which investors have quasi-hyperbolic time preferences and use dividend income as a commitment device to curb their tendency to over-consume. When accommodative monetary policy lowers interest rates, it reduces the income stream from bonds and induces investors who want to keep a desired level of consumption to "reach for income'' by...
|October 2016||Factions in Nondemocracies: Theory and Evidence from the Chinese Communist Party|
with , : w22775
This paper investigates theoretically and empirically the factional arrangements and dynamics within the Chinese Communist Party (CCP), the governing political party of the People's Republic of China. Our empirical analysis ranges from the end of the Deng Xiaoping era to the current Xi Jinping presidency and covers the appointments of both national and provincial officials. We present a set of new empirical regularities within the CCP and a theoretical framework suited to model factional politics within single-party regimes.
|November 2015||Regulation and Market Liquidity|
with : w21739
The aftermath of the 2008-09 U.S. financial crisis has been characterized by regulatory intervention of unprecedented scale. Although the necessity of a realignment of incentives and constraints of financial markets participants became a shared posterior after the near collapse of the U.S. financial system, considerable doubts have been subsequently raised on the welfare consequences of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and its various subcomponents, such as the Volcker Rule. The possibility of permanently inhibiting the market making capacity of large banks, with dire consequences in terms of under-provision of market liquidity, has been repeatedly raised. This paper presents systematic evidence from four different estimation strategies of the absence o...
