ABSTRACT

The imposition of international travel restrictions to prevent the spread of the Coronavirus has been a controversial issue. In this paper we examine the effect of international tourist arrivals on the population fatality rate and the case fatality, where fatality is caused by Covid-19, using a cross-sectional sample covering 146 countries. In addition to international tourist arrivals, 12 other explanatory variables are examined. Data on the dependent and explanatory variables were obtained from various sources, including the European Centre for Disease Prevention and Control, the World Bank, BBC and other sources. The role of internal population mobility is not considered explicitly, but it is captured by measures of lockdown that restrict movement. The results of the empirical analysis show that international tourist arrivals have a greater effect on the severity of Covid-19 than any of the other factors. This means that the imposition of international travel bans is justifiable by the objective of containing the virus.

摘要

实施国际旅行限制以防止冠状病毒传播一直是一个有争议的问题。在本文中，我们使用涵盖 146 个国家/地区的横截面样本，研究了国际游客人数对人口死亡率和病死率的影响，其中死亡是由 Covid-19 引起的。除了国际游客人数外，还检查了其他 12 个解释变量。因变量和解释变量的数据来自各种来源，包括欧洲疾病预防和控制中心、世界银行、BBC 和其他来源。内部人口流动的作用没有被明确考虑，但可以通过限制流动的封锁措施来体现。实证分析的结果表明，与其他任何因素相比，国际游客人数对 Covid-19 严重程度的影响更大。这意味着实施国际旅行禁令是为了遏制病毒的目标。
