Higher energy costs (owing to increases in both excise taxes and electricity rates), credit bottlenecks, specialization in stagnant export markets, and generalized policy uncertainty all seem to have played a role. As a result, Greek export prices have not come down nearly as much as wages.
这一事实本身表明回归德拉克马也许并不能给希腊带来多少裨益。希腊出口也许是因为其他因素才萎靡不振的。高企的能源价格（因为消费税和电费的增加）、信用瓶颈、细分专长恰好位于停滞出口市场，以及总体政策不确定都在起作用。结果，希腊出口价格的降幅不如工资。希腊退出也许有助于改善其中一些成本，但也会增加另一些成本（如政策不确定性）。
