Monetary and macroprudential policies to manage capital flows
研究在名义和金融摩擦并存的经济中，货币与宏观审慎政策如何互动，发现通胀目标制会加剧信贷和资产价格波动，而泰勒规则配合逆周期宏观审慎工具能改善福利。
We study interactions between monetary and macroprudential policies in a model with nominal and financial frictions. The latter derive from a financial sector that provides credit and liquidity services that lead to a financial accelerator-cumfire- sales amplification mechanism. In response to fluctuations in world interest rates, inflation targeting neutralizes nominal distortions but leads to increased volatility in credit and asset prices. Taylor rules do better, but the use of a countercyclical macroprudential instrument in addition to the policy rate improves welfare and has important implications for the conduct of monetary policy. “Leaning against the wind” or augmenting a Taylor rule with an argument on credit growth is not an optimal policy response.
