購買力
As a workaround many policy makers try to restore competitiveness through internal devaluation, a painful economic adjustment process, where a country aims to reduce its unit labour costs. German economist Hans-Werner Sinn noted in 2012 that Ireland was the only country that had implemented relative wage moderation in the last five years, which helped decrease its relative price/wage levels by 16%. Greece would need to bring this figure down by 31%, effectively reaching the level of Turkey. By 2012, wages in Greece have been cut to a level last seen in the late 1990s. Purchasing power dropped even more to the level of 1986.
