This could be the result of the indicator issuing signals relatively rarely. In this case there is also the danger that the indicator misses the crisis altogether it does not signal and there is a crisis . In this case we also wish to calculate for each indicator the proportion of crises accurately called PC C A C . In the next chapter we employ these concepts to provide evidence on the relative merits of a broad range of indicators in anticipating crises. 32 ASSESSING FINANCIAL VULNERABILITY Institute for International Economics http 3 Empirical Results The signals approach was applied to the indicators around the dates of the 29 banking and the 87 currency crises. In what follows we first compare our results for the 15 monthly indicators to those presented in Kaminsky and Reinhart 1999 and reproduced in table .
