Special events are typically regarded as major generators of economic activity and jobs. Despite its continued use in event assessment, Input-Output (I-O) analysis has been rejected in other areas of economic impact evaluation in favor of more rigorous evaluation techniques that recognize resource constraints in the economy and interindustry effects of demand shocks. This article discusses traditional and alternative perspectives on event assessment and the assumptions on which each approach are based. Illustrative results are then provided from a study that contrasted the economic impacts from a selected event analyzed by use of a traditional I-O approach, with estimates provided through the use of a more comprehensive computable general equilibrium (CGE) model. Issues involved in the wider use of CGE models for event assessment are discussed together with the need for further development in event evaluation techniques.

This paper explores the issues in estimating the greenhouse gas (GHG) emissions from the tourism industry and related activity in Australia. The scope of tourism consists of the economic activities defined as "tourism characteristic" and "tourism connected" as defined in the Australian Tourism Satellite Account (TSA). Two approaches are employed and contrasted -a "production approach" and an "expenditure approach". Depending on the approach, tourism contributes between 3.9% and 5.3% of total industry GHG in Australia. The rationale for each approach is explained. The GHG emissions have been estimated for 2003-2004, the latest year for which detailed industry GHG emissions data are available in a form suitable for this type of analysis. Tourism's GHG emissions are compared with other industries in the Australian economy. The policy implications of the results are discussed. It should be possible to adopt a broadly similar method for any destination with TSA -enabling tourism stakeholders to play an informed role in assessing appropriate and effective climate change mitigation strategies for their destination.

This article explores the use of computable general equilibrium (CGE) analysis in evaluating the economic impacts of special events. It is argued that CGE analysis is preferred to input-output (I-O) approaches for assessing other than local economic impacts. The article illustrates several differences between the alternative forms of analysis in event assessment. These include assessing the differential effects of events on the host region, other regions, and nationally and the ability to estimate interindustry effects. The article then shows how CGE models can be adapted to estimate the displacement effects of events, their fiscal impacts, intraregional effects, event subsidies, and multistate effects. The article also discusses how event impacts will vary depending on the extent of integration between regional and national resource markets and regional and national product and services markets and how labor markets are modeled.
