Financial crises, credit ratings, and bank failures : emerging market instability - do sovereign ratings affect country risk and stock returns? (original) (raw)

Upgrades tend to take place during market rallies, whereas downgrades occur during downturns, providing support to the idea that credit rating agencies contribute to the instability in emerging financial markets.

In addition we analyse the impact prior and after the 2008 financial crisis. The ramifying impact on emerging economies due to sovereign grade change given a 10 days event window prior and after the event is investigated. We use both a pooled...
