This paper assesses the industrial economic impacts of event host in Korea. An input-output model is used to estimate the economic inducement effects of an inaugural general assembly of the world toilet association in terms of output, value-added, and employment. The total expenditures are estimated to be about 4,575 million won. These receipts generate 9,353 million won of output, 2,650 million won of value-added, and 172 persons of employment as a result of their economic inducement effects. Such calculations allow the decision makers to estimate the opportunity costs of their decisions and can be regarded as the basis for an extended cost-benefit analysis. It concludes that there are considerable economic benefits for the event host country, although such benefits are not spreaded broadly across all industries.
