Many financial crises are at the global level, yet some of them can be country-specific, especially the ones connected with political instability.
For example, the 1990 recession of Russia, the 1958 recession in China, and the recent Brazil currency crisis is kind of independent of the global economic situation. The Eurozone crisis also only applies to a limit number of nations. Examples also include the Iceland bankruptcy.
So my question is, how could we identify those country-specific crises? Are there any established methods/datasets? Any references or ideas or suggests or guidelines will help!
