我们研究了两个后9/11机场的安全措施的影响-行李检查和联邦化的乘客检查-对航空旅行的需求在美国。利用机场分阶段引入的安全措施，我们发现行李检查使所有航班的乘客量减少了约6%，使从全国50个最繁忙机场起飞的航班减少了约9%。相比之下，联邦化的乘客筛查对乘客量几乎没有影响。我们提供的证据表明，需求的减少是行李检查的意外后果，而不是同期价格变化，机场特定的冲击，时间表变化或其他因素的结果。航空旅行的减少造成了巨大的损失。粗略计算表明，航空业因这一下降损失了约11亿美元，占9/11直接造成的损失的11%。
We examine the impact of two post-9/11 airport security measures-baggage screening and federalization of passenger screening-on demand for air travel in the United States. Exploiting the phased introduction of security measures across airports, we find that baggage screening reduced passenger volume by about 6 percent on all flights and by about 9 percent on flights departing from the nation's 50 busiest airports. In contrast, federalizing passenger screening had little effect on passenger volume. We provide evidence that the reduction in demand was an unintended consequence of baggage screening and not the result of contemporaneous price changes, airport-specific shocks, schedule changes, or other factors. This decline in air travel had a substantial cost. Back-of-the-envelope calculations indicate that the airline industry lost about $1.1 billion because of the decline, which is 11 percent of the loss attributed directly to 9/11.
