In recent years, portfolio flows to emerging markets have become increasingly large and volatile. Using weekly portfolio fund flows data, the paper finds that their short-run dynamics are driven mostly by global “push†factors. To what extent do these cross-border flows and global risk...

Why do asset price bubbles continue to appear in various markets? This paper provides an overview of recent literature on bubbles, with significant attention given to behavioral models and rational models with frictions. Unlike the standard rational models, the new literature is able to model...

This paper investigates whether financial crises are alike by considering whether a single modeling framework can fit multiple distinct crises in which contagion effects link markets across national borders and asset classes. The crises considered are Russia and LTCM in the second half of 1998,...

We study exchange rate and equity price dynamics, in general equilibrium, in the presence of news shocks about future productivity and monetary policy. We identify a condition under which these asset prices become more volatile without affecting the volatility of the underlying processes-a...

This paper focuses on evidence from stock markets as it investigates the spillovers from the United States to mainland China and Hong Kong SAR during the subprime crisis. Using both univariate and multivariate GARCH models, this paper finds that China's stock market is not immune to the...

This paper analyzes the impact of global and regional spillovers to GCC equity markets. GCC equity markets were impacted by spillovers from U.S. equity markets despite varying degrees of foreign participation. Spillovers from regional equity markets were also important but the magnitude of the...

We study equity price volatility in general equilibrium with news shocks about future productivity and monetary policy. As West (1988) shows, in a partial equilibrium present discounted value model, news about the future cash flow reduces asset price volatility. We show that introducing news...

This paper considers the role of country-level opacity (the lack of availability of information) in amplifying shocks emanating from financial centers. We provide a simple model where, in the presence of ambiguity (uncertainty about the probability distribution of returns), prices in emerging...

This paper examines how exchange rate volatility and Korean banks’ foreign exchange liquidity mismatches interacted with each other during the Global Financial Crisis, and whether the vulnerability stemming from this interaction has been reduced since then. Structural and cyclical changes...

This paper proposes a tractable Sudden Stop model to explain the main patterns in firm level data in a sample of Southeast Asian firms during the Asian crisis. The model, which features trend shocks and financial frictions, is able to generate the main patterns observed in the sample during and...
