Measurable or it hasn't happened: what quantitative threshold of investment decline precisely triggers a regulatory intervention of this magnitude?
Without a regression analysis demonstrating a strong link and a significant p-value, the claim of a direct trigger is speculative.
For example, data on previous investment declines and associated regulatory responses are necessary to assess whether this sample size is sufficient to establish a robust causality.
The new streaming quotas in Australia are probably the result of a convergence of factors, with the decline being just one catalyst among others, not the sole and sufficient trigger.
