most obviously, the existing chronologies sometimes differ substantially from one another. for example, both Reinhart and Rogoff(2009a) and the international Monetary fund (IMF) systemic Banking crises Database ( Laeven and valencia,2014) identify a crisis in norway following the collapse of house price in the late 1980s ; but Reinhart and Rogoff date it as occurring from 1987 to 1993,while the IMF dates it as running from the second half of 1991 to 1993.
