The economic impact calculation is based on the Input-Output Model (I-O). The model identifies how individual industries rely on inputs from other sectors, generating a chain reaction that produces multiplier effects throughout the region. Through this structure, intersectoral impacts are estimated, along with the way sales and purchases circulate across economic activity. For the direct impact, data on the workforce and coefficients are used to calculate output, Gross Value Added (GVA), and employment. The result is a full impact analysis that shows the economic value of music in the region and supports policymakers, industry stakeholders, and communities in understanding the broader economic implications of the music ecosystem.
