The European Commissionu2019s Scoreboard of Macroeconomic Imbalances u2013 The Impact of Preferences on an Early Warning System

摘要

The European Commission's Scoreboard of Macroeconomic Imbalances is a rare case of a publicly released early warning system (EWS). That allows for analyzing the preferences of the involved politicians with regard to the two potential errors of an EWS - missing a crisis and issuing a false alarm. This is done for the first time for EWS in general by using a standard signals approach including a preference-based optimization approach to set thresholds. It is shown that in general, the thresholds of the scoreboard are set low (resulting in more alarm signals) as compared to a neutral stand.
