摘要

COVID-19 对航空业造成了巨大的破坏。本文分析了大流行病对机票价格离散性的影响。样本包括 DB1B 数据库中 2018Q1 至 2021Q4 的机票信息。固定效应面板工具变量（IV）估计发现了 COVID-19 期间价格离散性下降的证据。这些结果对其他离散度量和子样本都是稳健的。此外，子样本分析表明，随着感染率的上升，竞争更激烈的市场的离散度下降幅度更大。具体而言，有低成本航空公司（LCC）存在的航线的离散度低于完全由传统航空公司提供服务的航线，短途航线（≤500 英里）的离散度低于长途航线（>500 英里）。我的分析利用最新数据，探讨了市场条件变化（即 COVID-19 衰退引发的需求冲击）对价格和价格离散度的影响，从而为相关文献增添了新的内容。

Does COVID-19 decrease price dispersion? Recent evidence from the airline industry

COVID-19 has caused substantial disruptions to the airline industry. This paper analyzes the impact of the pandemic on price dispersion in airfares. The sample includes ticket information from the DB1B database between 2018Q1 and 2021Q4. The fixed-effect panel instrument variable (IV) estimation finds evidence of decreased price dispersion during COVID-19. These results are robust to alternative measures of dispersion and subsamples. Furthermore, the subsample analyes reveal that, as the infection rate rises, the dispersion decreases more in markets where competition is more intense. Specifically, dispersion is lower on routes with the presence of low-cost carriers (LCCs) than those exclusively served by legacy carriers and on short-haul routes ( $\leq$ 500 miles) than long-haul routes ( $>$ 500 miles). My analysis adds to the literature by exploiting the impact of changes in market conditions (i.e., demand shocks triggered by the COVID-19 recession) on price and price dispersion using the latest data.

期刊介绍： Established in 1947, Research in Economics is one of the oldest general-interest economics journals in the world and the main one among those based in Italy. The purpose of the journal is to select original theoretical and empirical articles that will have high impact on the debate in the social sciences; since 1947, it has published important research contributions on a wide range of topics. A summary of our editorial policy is this: the editors make a preliminary assessment of whether the results of a paper, if correct, are worth publishing. If so one of the associate editors reviews the paper: from the reviewer we expect to learn if the paper is understandable and coherent and - within reasonable bounds - the results are correct. We believe that long lags in publication and multiple demands for revision simply slow scientific progress. Our goal is to provide you a definitive answer within one month of submission. We give the editors one week to judge the overall contribution and if acceptable send your paper to an associate editor. We expect the associate editor to provide a more detailed evaluation within three weeks so that the editors can make a final decision before the month expires. In the (rare) case of a revision we allow four months and in the case of conditional acceptance we allow two months to submit the final version. In both cases we expect a cover letter explaining how you met the requirements. For conditional acceptance the editors will verify that the requirements were met. In the case of revision the original associate editor will do so. If the revision cannot be at least conditionally accepted it is rejected: there is no second revision.
