The economic contribution of advertising in Europe
The World Federation of Advertisers (WFA), with the support of a wide range of industry stakeholders  commissioned Deloitte to quantify the economic impact of advertising, both across Europe and in a selection of other developed markets.
This report has one over-riding objective: to demonstrate what the contribution of advertising to the European and national economies is, as well as assessing its tangible benefits to EU citizens.
This was no easy task, as there are a large number of factors which can influence GDP. However, Deloitte created an econometric model to isolate the benefits of advertising to the European economy, and to individual EU markets or countries such as Japan and Canada.
The model was based on 17 years of Advertising Association/WARC  data (1998 – 2014) from 35 developed markets, and found that advertising spend in the EU has a seven-fold impact on the wider economy.
