Discontinuity and the Theory of International Migration
这篇探索性论文将（强）不连续性概念引入国际劳动力迁移理论，提出仅凭国家间工资差异可能不足以引发移民，但结合风险规避、相对剥夺和信息不对称这三个因素，可以解释国际移民现象。
SUMMARY In this exploratory paper, the notion of (strong) discontinuity is introduced into the theory of international labour migration. It is suggested that inter‐country wage differentials alone may fail to induce international migration at the level of the decision making entity. However, three factors ‐ risk aversion, relative deprivation and asymmetric information ‐ in conjunction with these wage differentials, may account for international migration.
