In line with my own thinking at this point. The FT article ostensibly attempts to define a depression but in doing so goes out of its way to single out Ireland as being one that will meet the most extreme definition of a depression - a 20%+ economic decline from peak to trough.
Yup, 20% is about where I see it going. I base this on the level of competitiveness required to get to EU averages - reduction in utility costs, reduction in wage costs etc.
These will feed into a lower level of economic activity, as in the monetary value of the activity will be lower, even if actual activity levels stay the same.
Add to this the reduction due to returning the construction sector to a stable size (from 25% of GDP to 10% of GDP).
Of course, this doesn’t allow for a recessionary overshoot - this is just to get back to a sustainable level of GDP from which real growth is possible.
