Expanding on his dissertation thesis, completed in 2003, Professor Paolo Pasquariello's powerful insight (published in 2007) demonstrates that financial contagion (the spread of a shock from one financial market to many) could occur due to the simple, and highly plausible, heterogeneous private information of speculators about fundamentals. Financial contagion is an increasingly common phenomenon of global concern, especially during financial crises. Importantly, Pasquariello's theoretical multi-market setting rules out all the more complicated explanations of contagion --- usual suspects such as correlated information and/or liquidity and portfolio rebalancing --- while linking it to some of the main features of globalization, the expansion of and access to international financial markets.
