Cyclical fluctuations in nominal variables--aggregate price levels and nominal interest rates--are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal...

This paper examines the effect of exogenous shocks to savings on world capital markets. Using the exogenous shocks to US tax policy identified by Romer & Romer, we trace the impact of an exogenous shock to savings through the income accounting identities of the US and the rest of the world. We...

This paper illustrates the paradox of prudential under-regulation in an economy that adopts financial reform, a reform which exposes the economy to future financial crises. There is individual-uncertainty about the crisis incidence, and the probability of the crisis is updated sequentially...

This paper investigates the behavior of public debt in countries forming a union (as outlined, e.g., by the Maastricht treaty). We consider a federal union of states where the center has limited control over the spending patterns of the union members, and where the union members' behavior has...

In this paper we study the degree to which Emerging Markets (EMs) adjusted to the global liquidity crisis by drawing down their international reserves (IR). Overall, we find a mixed and complex picture. Intriguingly, only about half of the EMs depleted their IR as part of the adjustment...

Using a novel dataset on changes in capital controls and currency-based prudential measures in 17 major emerging market economies (EMEs) over the period 2001-2011, this paper provides new evidence on domestic and spillover effects of capital controls before and after the global financial crisis....

Since the 2008 global financial crisis, and after decades of relative neglect, the importance of the financial system and its episodic crises as drivers of macroeconomic outcomes has attracted fresh scrutiny from academics, policy makers, and practitioners. Theoretical advances are following a...

We provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such...

This paper provides a theoretical framework for quantitatively investigating the optimal accumulation of international reserves as a hedge against rollover risk. We study a dynamic model of endogenous default in which the government faces a tradeoff between the insurance benefits of reserves and...

This paper analyzes the case for the international coordination of macroprudential policies in the context of a simple theoretical framework. Both domestic macroprudential policies and prudential capital controls have international spillovers through their impact on capital flows. The...
