Consumer spending during COVID-19 in a tourism city
利用韩国济州岛的大规模交易数据，量化了COVID-19疫情及政策应对对居民和国内游客消费行为的影响，发现居民对本地病例更敏感，而游客受本地和全国病例影响相当，社交距离政策对游客消费打击超20%，刺激支付则提升居民消费超10%。
Leveraging large-scale transaction data, this study quantifies the impact of COVID-19 and policy responses on the spending behavior of both residents and domestic inbound travelers in Jeju, Korea. Findings reveal that both local and national COVID-19 situations significantly affected the spending behavior of both groups. Residents were more sensitive to local cases, while travelers were equally affected by local and national cases. Social distancing minimally impacted resident spending but caused over 20 % reductions in traveler spending. Stimulus payments boosted spending by over 10 % for residents without diminishing the effects of social distancing. Despite the overall benefit of these combined policies, certain economic sectors benefited notably while others suffered, thus leaving them with varying fates during and after the pandemic.
