Recent crises have seen very large spikes in asset price risk without dramatic shifts in fundamentals. We propose an explanation for these risk panics based on self-fulfilling shifts in risk made possible by a negative link between the current asset price and risk about the future asset price....

Recent crises have seen large spikes in asset price risk. We propose an explanation for such panics based on self-fulfilling shifts in beliefs about risk. A negative link between the current level and the future risk of an asset price leads to a circular relationship between the stochastic...

There has been a long debate about whether speculators are stabilizing or not. We consider a model where speculators have a stabilizing role in normal times, but may also provoke large risk panics. The very feature that makes arbitrageurs liquidity providers in normal times, namely their...

The sharp increase in both gross and net capital flows over the past two decades has led to a renewed interest in their determinants. Most existing theories of international capital flows are in the context of models with only one asset, which only have implications for net capital flows, not...

The surge in international asset trade since the early 1990s has lead to renewed interest in models with international portfolio choice, an aspect that was largely cast aside when the ad-hoc portfolio balance models of the 1970s were replaced by models of optimizing agents. We develop the...

We develop a new theory of international capital flows based on dispersed information across individual investors. There is extensive evidence of information heterogeneity within and across countries, which has proven critical to understanding asset price behavior. We introduce information...
