Two questions are addressed. First, what explains the incidence and severity of financial crises in an emerging market economy？ And, second, what is the role of learning; how does the country learn from its past experience in financial crises to improve institutions and develop better techniques so as to successfully manage successive crisis events？ To the best of our knowledge, this is the first attempt to provide a crisis event taxonomy looking at a systematic categorisation of the crises episodes that the country experienced over its 200-year life span, from its independence and the foundation of the Modem Greek state in 1829 to the recent 2008 crisis. To answer the above questions, I first present evidence on financial crises in Greece over a long time span of two centuries. Greece is chosen as our working template since it is a country with a rich history in financial crises. In particular, we try to identify different varieties of crises events, providing thus a crisis chronology. Moreover, we present some stylised facts on the incidence, the frequency and the severity of crises events. And second, we discuss the key determinants of the crises episodes, closely related to country specific factors, such as credit expansion, fiscal imbalances and the limited reserve coverage of the monetary base.展开更多
