Incentivize grandchildren by writing them into your will
It’s no secret that I’m a fan of economics-inspired solutions to otherwise hard problems. The other day I happened across an old post by GMU economist Bryan Caplan which I think does this very elegantly, for a problem of some interest to me.

It makes it unambiguously clear where your priorities in the case of your untimely demise lie. It is also self-reinforcing; children of yours who have no children themselves will recieve less, but when it comes time to write their own wills, they won’t have any children or grandchildren to bequeath to anyway. Children of yours who have many children themselves, perhaps inspired by this very policy, might decide in the end they were duped - but it seems far more likely to me they’ll cite it as one of the biggest reasons they ultimately went for 4 instead of 3, or 2 instead of 1, or 1 instead of none. After seeing it work in practice on themselves, they might decide they want to incentivize bringing their own grandchildren into being in kind. ...
