Achieving the primary objective of price stability without unduly compromising the operational efficiency of the payment system constitutes a major problem for central banks. Routine monetary policy presumes a given institutional and technological framework, including aspects of the payment...

Although capital inflows are generally beneficial to recipient countries, they also pose a challenge for the conduct of economic policy. This paper proposes a conceptual taxonomy to guide the design of policy responses in the face of capital flows. We explore how responses to capital surges...

We study the welfare properties of an economy where both monetary and fiscal policy follow simple rules, and where a subset of agents is borrowing constrained. The optimized fiscal rule is far more aggressive than automatic stabilizers, and stabilizes the income of borrowingconstrained agents,...

In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate...

This paper explores how prudential regulations can support monetary policy in reducing output fluctuations while maintaining financial stability. It uses a new framework that blends a standard model for monetary policy analysis with a contingent claims model of financial sector vulnerabilities....

This paper discusses the potential macroeconomic implications for Hong Kong SAR of accommodative monetary policy in the United States. It shows, through model simulations, that a resumption of the credit channel in Hong Kong SAR has the potential to create inflation in both goods and asset...

We argue that a stronger emphasis on macrofinancial risk could provide stabilization benefits. Simulations results suggest that strong monetary reactions to accelerator mechanisms that push up credit growth and asset prices could help macroeconomic stability. In addition, using a macroprudential...
