What is the measure that specifically proves that an 18% decrease in audiovisual investments in Australia triggered the announcement of streaming quotas, rather than being one indicator among others?
Without a defined threshold and a representative sample of similar situations, this direct causality is a conjecture.
Major regulatory decisions are rarely the unambiguous consequence of a single economic metric.
For example, countries like Canada have been able to implement robust cultural quotas without necessarily reacting to an immediate decline to support their local industry, demonstrating a proactive political will and not just reactive, independent of the investment dynamics.
How much decline would be necessary for such an intervention to be statistically observable as the sole cause?
