假如葡萄牙退出欧元区，重新引入埃斯库多（葡萄牙货币单位 ） ， 那么随后而来的汇率贬值会使葡萄牙出口产品价格下跌，进口产品价格上涨，刺激葡萄牙经济发展，带来其急需的经济增长。
Suppose, for example, that Portugal were to leave and re-introduce the escudo. The ensuing exchange-rate devaluation would immediately lower the price of Portugal’s exports, raise its import prices, stimulate the economy, and bring about much-needed growth.
