"We present a model for deriving optimal sequential migration decisions under incomplete information. As a main characteristic of the model, the decision maker can rationally learn about pecuniary and non-pecuniary net return on migration in different countries by migrating into these countries. Furthermore it is shown that the optimal migration policy can be characterized by a 'simple' procedure, called 'Gittins-index policy'. In the context of our sequential migration model we find more satisfying explanations for some relevant empirical observations (e.g. remigration) than...would be possible within the traditional deterministic approach."

我们提出了一个在信息不完整的情况下推导最优顺序迁移决策的模型。作为该模型的一个主要特征，决策者可以通过迁移到不同国家来合理了解在这些国家迁移的货币和非货币净回报。此外，研究表明，最优迁移政策可以由一个称为“吉廷斯指数政策”的“简单”程序来表征。在我们的顺序迁移模型的背景下，我们对一些相关的实证观察结果（例如再迁移）找到了比传统确定性方法所能给出的更令人满意的解释。 （法语和德语摘要）
