Abstract
The analysis of the impact of mega events has included frameworks that evaluate different impacts under different criteria, for example, separating impacts according to whether they occur before, during or after the event itself. Analysis of the economic impacts of such events has shown that the distributional effects between the host city and the rest of an economy can be important, and can have opposite signs. This paper introduces frameworks to show the origin of the economic scale, that is, Olympic-related investment and expenditure, and shows how the frameworks can be used with reference to the Beijing 2008 Olympics.
