Abstract

This paper theoretically investigates externalities and policy interventions in travel during a pandemic. We develop a tractable static model of two regions from a short-run perspective. The model shows that the externalities can be both negative and positive, depending on regional asymmetry. Thus, even when infectious diseases are widespread, travel restrictions do not necessarily reduce infections and do not necessarily improve social welfare. A formula for the optimal policy intervention is derived and shown to be the weighted average of four types of externalities defined by the direction of travel and the epidemiological status of a traveler.

传染病区域间旅行的外部性和政策干预。

本文从理论上研究了大流行病期间旅行的外部性和政策干预。我们从短期角度建立了一个两个地区的可操作静态模型。模型显示，外部性既可能是负的，也可能是正的，这取决于地区的不对称性。因此，即使在传染病广泛传播的情况下，旅行限制也不一定能减少感染，也不一定能提高社会福利。最佳政策干预的公式是由旅行方向和旅行者的流行病学状况决定的四种外部性的加权平均值。

期刊介绍： This Journal publishes articles on all aspects of health economics: theoretical contributions, empirical studies and analyses of health policy from the economic perspective. Its scope includes the determinants of health and its definition and valuation, as well as the demand for and supply of health care; planning and market mechanisms; micro-economic evaluation of individual procedures and treatments; and evaluation of the performance of health care systems. Contributions should typically be original and innovative. As a rule, the Journal does not include routine applications of cost-effectiveness analysis, discrete choice experiments and costing analyses. Editorials are regular features, these should be concise and topical. Occasionally commissioned reviews are published and special issues bring together contributions on a single topic. Health Economics Letters facilitate rapid exchange of views on topical issues. Contributions related to problems in both developed and developing countries are welcome.
