As a result of the role played by migrants in supporting host economies, the interest in understanding the impact of migration is growing. However, the literature remains silent on the channels by which migration affects tourism. The present article aims to isolate the effect of migrant networks on tourism by exploring the role of information, travel costs, and demand for visiting friends and relatives. To this end, a theoretical framework that rests upon a structural gravity model is developed. The model allows not only a better understanding of the relationship between tourism and migration but also to overcome several empirical biases like the omission of multilateral resistance in tourism flows or controlling for endogeneity. The empirical analysis considered a sample of 34 OECD countries as destination/home and 157 origin/countries-of-birth for tourist arrivals/migration stock. A positive and robust effect of migration on inbound tourism is estimated and the three channels proposed to drive this nexus become relevant.

由于移民在支持东道国经济中所发挥的作用，人们越来越了解移民的影响。但是，文献对移民影响旅游业的渠道保持沉默。本文旨在通过探索信息，旅行成本以及探亲访友的需求来隔离移民网络对旅游业的影响。为此，建立了基于结构重力模型的理论框架。该模型不仅可以更好地理解旅游业与移民之间的关系，还可以克服一些经验偏差，例如在旅游业流中遗漏多边阻力或控制内生性。实证分析认为，有34个经合组织国家的样本作为目的地/家乡和157个原籍/出生国作为游客/移民存量。据估计，移徙对入境旅游业产生了积极而强劲的影响，并提出了推动这种联系的三种途径。
