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

It is well known from anecdotal, survey and econometric evidence that the relationshipbetween the exchange rate and macro fundamentals is highly unstable. Thiscould be explained when structural parameters are known and very volatile, neitherof which seems plausible. Instead we argue that large...

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...
