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...

From late 2008 to 2017, oil and equity returns were more positively correlated than in other periods. In addition, we show that both oil and equity returns became more responsive to macroeconomic news. We provide empirical evidence and theoretical justification that these changes resulted from...

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...

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...

We investigate whether the response of the macro-economy to oil price shocks undergoes episodic changes. Employing a regime-switching vector autoregressive model we identify two regimes that are characterized by qualitatively different patterns in economic activity and inflation following oil...

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...

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...

Economic research in recent years has given considerable prominence to the issue of whether a floating exchange rate provides autonomy with regard to monetary policy to a central bank whose economy is highly open. In particular, Rey (2016) has argued that inflation-targeting advanced economies...
