This study examines the impacts of a rise in international tourism on the welfare of residents. We construct a simple model in which a home country accommodates tourists from a foreign country. We pay special attention to the fact that, in addition to the positive effect of raising wages, tourism growth has two negative effects. First, it replaces the production of residents’ consumption varieties with that of tourists. Second, it raises output prices through the increase in input prices. Our model shows that growing tourism can hurt a worker in the home country when the two negative effects (variety-shifting and price effects) outweigh the positive effect (wage effect).

本研究考察了国际旅游业的兴起对居民福利的影响。我们构建了一个简单的模型，其中本国接待来自外国的游客。我们特别注意到，除了提高工资的积极作用外，旅游业的增长还有两个消极作用。一是以游客消费替代居民消费品种的生产。其次，它通过提高投入品价格来提高产出品价格。我们的模型表明，当两个负面影响（品种转移和价格影响）超过正面影响（工资效应）时，增长的旅游业会伤害本国的工人。
