When a central bank implements the LOLR policy in a financial crisis, bank creditors often infer a bank's quality from whether or not it borrows from the central bank. We establish a formal model to study the optimal LOLR policy in the presence of this signaling effect, assuming that the central...

This paper examines empirical evidence of the adaptive learning behavior of speculators in the 2005–2008 renminbi appreciation episode, and establishes a theoretical model to explore appreciation policy implications of such a behavior. In our model, speculators form their expectations about...

This paper studies contagion and market freezes caused by uncertainty in financial network structures and provides theoretical guidance for central banks. We establish a formal model to demonstrate that, in a financial system where financial institutions are interconnected, a negative shock to...

This paper examines the optimal appreciation path of an under-valued currency in the presence of speculative capital inflows that are endogenously affected by the appreciation path. A central bank decides the optimal appreciation path based on three factors: (i) Misalignment costs associated...

This paper examines the optimal appreciation path of an undervalued currency in the presence of speculative capital inflows that are endogenously affected by the appreciation path. A central bank decides its appreciation policy based on three costs: (i) misalignment costs associated with the gap...
