How Can Residents’ Air Transport Subsidies Affect Outbound Tourism behavior on Islands? Evidence from Spain
研究了西班牙两个群岛居民航空补贴增加对出境旅游行为的影响，发现补贴提高后居民停留时间减少10%-15%，但巴利阿里群岛的日均支出增加13%，加那利群岛则无显著变化。
Subsidizing residents on airlines is a common policy in a number of countries. However, the question arises as to how changes in this policy affect the travel behavior of residents in specific regions? To address this, we analyze the effect of an “exogenous shock” (i.e., an increase in the resident subsidy) on two Spanish archipelagos when they travel away from the islands. Our Difference-in-Difference and matching estimations find that the causal impact of the policy change is different for resident passengers across the two regions affected. Although the length of stay was reduced for resident passengers in both archipelagos by 10%–15% after the shock, their expenditure at destination per day increased by 13% on the Balearic Islands, while showing no significant change on the Canary Islands.
