We have entered a world of conjoined monetary and macroprudential policies. But can they function smoothly in tandem, and with what effects? Since this policy cocktail has not been seen for decades, the empirical evidence is almost non-existent. We can only fix this shortcoming in a historical...

Financial crises cause economic, social and political havoc. Macroprudential policies are gaining traction but are still severely under-researched compared to monetary and "fiscal policy. We use the general framework of sequential predictions, also called online machine learning, to forecast...

We investigate the origins and growth of the Financial Stability Mandate (FSM) to examine why bank supervisors, inside and outside of central banks succeeded or failed to meet their FSM. Three issues inform this study: (1) what drives changes in the FSM, (2) whether supervision should be...

This paper examines the consequences of the 2015 reform on the London fixing in the interbank forex market, which resulted from finding and imposing a penalty on banks' collusive behavior around the fixing window. The banks changed their behavior after the reform, and the volume spike in the...

We review the findings of the literature on the benefits of international financial flows and find that they are quantitatively elusive. We then present evidence on the existence of a global cycle in gross cross border flows, asset prices and leverage and discuss its impact on monetary policy...

China's securities markets are unlike those of Amsterdam, London or New York. Those markets evolved over centuries from myriad interactions among those seeking finance on the one hand and savers seeking rewarding investments on the other. Such spontaneous securities markets did emerge throughout...

The interaction between credit frictions, financial innovation, and a switch from optimistic to pessimistic beliefs played a central role in the 2008 financial crisis. This paper develops a quantitative general equilibrium framework in which this interaction drives the financial amplification...

This paper develops methods for assessing the sensitivity of capital flows to global financial conditions, and applies the methods in assessing the impact of macroprudential policies introduced by Korea in 2010. Relative to a comparison group of countries, we find that the sensitivity of capital...

Collateral constraints widely used in models of financial crises feature a pecuniary externality: Agents do not internalize how borrowing decisions taken in “good times” affect collateral prices during a crisis. We show that agents in a competitive equilibrium borrow more than a financial...

"Liability dollarization,'' namely intermediation of capital inflows in units of tradables into domestic loans in units of aggregate consumption, adds three important effects driven by real-exchange-rate fluctuations that alter standard models of Sudden Stops significantly: Changes on the debt...
