Abstract
The scale of the Olympic Games has expanded since the 1984 Los Angeles Olympics due to globalization and commercialization. In recent years, many large cities have participated in bidding for the Summer Olympic Games because the Games are held on a scale that can produce demands on the construction sector, such as for the construction of stadiums and transportation links, and on the service sector, such as in the case of the media and tourism. The aim of this study is compare the impact on the host cities of the Summer Olympic Games, between the 1984 Los Angeles Games and the 2020 Tokyo Games. As data, I have used the main stock market index of the countries that have hosted the 10 Summer Olympic Games between 1984 and 2020. The change ratio is measured with 1 business day and 5 business days. The 2020 Tokyo Olympic Games showed a positive impact, although Japan has a larger economic scale than other host countries in the past ten Summer Olympic Games.
