摘要

以2017年韩国浦项地震为自然实验，我们检验了人口的反应。通过使用综合控制构建浦项的反事实，我们发现地震显著减少了当地人口。为了调查人口减少的机制，我们收集了关于地址变化和自我报告的移民原因的行政数据。虽然由于居住环境的变化而导致的外出移民显著增加，但与工作相关的移民变化不大。这种向外迁移也导致了租赁住房价格的贬值。我们的研究结果表明，当地居民认为地震是一种负面的便利设施。

Natural disasters, risk and migration: evidence from the 2017 Pohang earthquake in Korea

Using the 2017 Pohang earthquake in South Korea as a natural experiment, we examined the responses of the population. By constructing a counterfactual of Pohang using synthetic controls, we found that the earthquake significantly decreased the local population. To investigate the mechanisms of population decrease, we gathered administrative data on the universe of address changes and self-reported reasons for migration. While out-migration due to changes in the residential environment increased significantly, job-related migration showed little change. This out-migration also led to a depreciation in rental housing prices. Our results suggest that local residents perceived the earthquake as a negative amenity.

The journal is steered by a distinguished team of Editors and an Editorial Board, drawn equally from the two disciplines. It publishes original academic research and discussion of the highest scholarly standard in the field of ''economic geography'' broadly defined. Submitted papers are refereed, and are evaluated on the basis of their creativity, quality of scholarship, and contribution to advancing understanding of the geographic nature of economic systems and global economic change.
