This study estimates the effect of official development assistance (ODA) on tourism demand of recipient countries for donor countries. We analyzed a panel dataset of 15 recipient countries of Switzerland’s aid from 2005 to 2017, for which data are available. We used both tourist arrivals at lodging establishments, particularly hotels, in Switzerland and hotel nights as proxies for recipient countries’ tourism demand in Switzerland. Using a modified gravity model of trade for empirical testing, we found that an increase of every US$1000 ODA to recipient countries would generate 3.6 tourist arrivals and almost four hotel nights in the following year, after controlling for the effects of GDP and population of recipient countries, the exchange rate and the distance between recipient countries and Switzerland, and trade facilitators. We conclude that ODA generates a positive externality on donor countries, namely, that recipient countries incline to increase their imports from donor countries, at least partially in the form of inbound tourism in donor countries.

本研究估计了官方发展援助 (ODA) 对受援国对捐助国旅游需求的影响。我们分析了 2005 年至 2017 年瑞士援助的 15 个受援国的面板数据集，这些数据是可用的。我们使用瑞士住宿设施（尤其是酒店）的游客人数和酒店住宿时间作为接收国在瑞士旅游需求的指标。使用修正的贸易引力模型进行实证检验，我们发现，在控制 GDP 和受援国人口的影响后，对受援国每增加 1000 美元 ODA 将在接下来的一年中产生 3.6 名游客人数和近 4 个酒店住宿晚数。国家、汇率和受援国与瑞士之间的距离，以及贸易促进者。
