When will corporations get scared? When the insurance dries up? New Zealand can't hold all the world's millionaires and billionaires. If there's a rush, then that money won't matter much.
That those economic predictions are based on assumptions with a high degree of hand waving doesn’t matter, they want to believe.
In my personal experience, n=1, it appears that most publicly traded corporations are concerned with the future as far out as 4 financial quarters, maximum.
Executive compensation is tied to stock price, so that is the depth of focus.
I have only had one gig at a public company, and it put me off of at working at another. Any longer term planning was derailed by a VP coming into a meeting, spewing shortsighted nonsense, and running off to the next thing.
edit: There are notable exceptions to this short term thinking, but those appear to be corps where a founder was still at the helm. ex: NVIDIA, Tesla.
