In this paper, we discuss the evolution of central bank interactions since the early 1970s following the breakdown of the managed exchange-rate system that was negotiated at Bretton Woods. We review the most important forums or organizations through which central banks have engaged in diplomacy....

In this paper, we consider how monetary policy in a large, foreign economy affects optimal monetary policy in a small open economy ('home') in response to a large global demand shock that pushes both economies to the zero lower bound (ZLB) on nominal interest rates. We show that the inability of...

I develop a model where the sovereign debt capacity depends on the capitalization of domestic banks. Low-capital banks optimally tilt their government bond portfolio toward domestic securities, linking their destiny to that of the sovereign. If the sovereign risk is sufficiently high,...

As a result of legal restrictions on branch banking, an extensive interbank system developed in the United States during the 19th century to facilitate interregional payments and flows of liquidity and credit. Vast sums moved through the interbank system to meet seasonal and other demands, but...

During the 2007-2010 financial crisis, central banks accumulated a vast amount of experience in acting as lender of last resort. This paper reviews the various ways that central banks provided emergency liquidity assistance (ELA) during the crisis, and discusses issues for the design of ELA...

Despite the extensive attention that the Basel capital adequacy standards have received internationally, significant variation exists in the implementation of these standards across countries. Furthermore, a significant number of countries increase or decrease the stringency of capital...

I examine the effect of a firm's tradability, the proportion of output that is exported abroad, on its stock returns. There are three novel empirical findings: (1) firms with higher tradability have more cyclical asset returns; (2) firms with higher tradability have more cyclical earnings...

How does financial integration impact capital accumulation, current-account dynamics, and cross-country inequality? This paper investigates this question within a two-country, general-equilibrium, incomplete-markets model that focuses on the importance of idiosyncratic entrepreneurial risk -- a...

When available financial securities allow investors to optimally diversify risk across countries, standard theory implies that exchange rates should reflect this behavior. However, exchange rates observed in the data deviate from these predictions. In this paper, we develop a framework to value...

Global and local methods are widely used in international macroeconomics to analyze incomplete-markets models. We study solutions for an endowment economy, an RBC model and a Sudden Stops model with an occasionally binding credit constraint. First-order, second-order, risky steady state and...
