The Effects of Hosting Mega Sporting Events on Local Stock Markets and Sustainable Growth

We examine the economic effects of the Summer and Winter Olympic Games and the FIFA World Cup on the economies of host countries. We found that in the short run, hosting the Olympic Games has a significant positive announcement effect on the host country's equity market. Our results also revealed a positive effect on the stock market in non-G7 countries hosting a mega sporting event and an insignificant effect in G7 countries hosting such events, indicating that hosting a mega sporting event can provide additional momentum for developing or emerging economies. We did find, however, that while the countries hosting the Summer Olympic Games initially experienced significant positive GDP growth, the effect rapidly diminished after the event. Our results suggest that hosting a mega sporting event such as the Summer Olympic Games is most likely to result in a short-term positive economic momentum, however it hinders sustainable growth for the host countries' economies.
