Advocates of trade liberalization touted its advantages; but they were never fully honest about its risks, against which markets typically fail to provide adequate insurance. Over a quarter-century ago, I showed that, under plausible conditions, trade liberalization could make everyone worse off.
贸易自由化的鼓吹者们强调它的优势；但是他们对于其风险从来都不是开诚布公。市场对于这些风险通常并不提供足够的保险。我在25年以前证明，在可能的条件下，贸易自由化有可能让所有人都日子更加难过。我并不是主张保护主义，而是提出忠告，也就是我们必须清楚负面风险并且准备好应付它们。
