The 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...

In an in‡uential series of contributions, Kraay and Ventura (2000, 2003) o¤er a“new rule” for the current account: in response to a temporary income shock, thechange in the current account is equal to the change in saving times the ratio of netforeign assets to wealth. We analyze the...

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