A Kick for the GDP: The Effect of Winning the FIFA World Cup
利用OECD数据，通过事件研究和合成双重差分法，发现赢得世界杯使后续两个季度的GDP同比增长率至少提高0.48个百分点，主要源于出口增长。
This paper uses OECD data to examine whether winning the men's FIFA World Cup boosts GDP growth, as claimed by analysts and media outlets concomitantly with every edition of this football competition. By implementing both an event‐study design and a synthetic difference‐in‐difference strategy, the analysis shows that winning the World Cup increases year‐over‐year GDP growth by at least 0.48 percentage points in the two subsequent quarters. This result seems primarily driven by enhanced export growth, which is consistent with a greater appeal enjoyed by national products and services on the global market after victory in a major sporting event.
