The irony here is that the impetus toward currency union was partly a result of the recognition of asymmetries. Thus, in the aftermath of the sterling and lira devaluations of the early 1990’s, with their resulting adverse trade shocks to France and Germany, the lesson that was drawn was that a single currency was needed to prevent such disparate shocks from recurring.
讽刺之处在于，从某种意义上说，迈向货币联盟的动力是对不对称的认识。因此，20世纪90年代初英镑和里拉贬值后，法国和德国受到了消极的贸易冲击，人们从中汲取的教训是需要单一货币来防止这类不同冲击再次发生。
