We investigate global factors associated with cross-border capital flows. We formulate a model of gross capital flows through the international banking system and derive a closed form solution that highlights the leverage cycle of global banks as being a prime determinant of the transmission of...

We study the dynamics linking monetary policy with bank leverage and show that adjustments in leverage act as the linchpin in the monetary transmission mechanism that works through fluctuations in risk-taking. Motivated by the evidence, we formulate a model of the "risk-taking channel" of...

The classical gold standard period, 1880-1913, witnessed deep economic integration. High capital imports were related to better growth performance but may also have created greater volatility via financial crises. I first document the substantial output losses from various types of crises. I...

"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...

This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

This lecture argues that the Global Financial Cycle is a challenge for the validity of the Mundellian trilemma. I present evidence that US monetary policy shocks are transmitted internationally and affect financial conditions even in inflation targeting economies with large financial markets....

This paper examines policy responses to exchange-rate movements in a simple model of an open economy. The optimal response of monetary policy to an exchange-rate change depends on the source of the change: on whether the underlying shock is a shift in capital flows, manufactured exports, or...

Intuitively, the observed 'home bias' in individual portfolios plausibly explains the international capital immobility in aggregate data reported by Feldstein and Horioka (1980) as well as the survival of taxes on capital income. These intuitions are examined explicitly in a model where random...

In the wake of the 1997-98 financial crises, interest rates in Asia were raised immediately, and then reduced sharply. We describe an environment in which this is the optimal monetary policy. The optimality of the immediate rise in the interest rate is an example of the theory of the second...

This paper explores the nature of macroeconomic spillovers from advanced economies to emerging market economies (EMEs) and the consequences for independent use of monetary policy in EMEs. We first empirically document the effects of US monetary policy shocks on a sample group of EMEs. A...
