How long after a President leaves office does it take for his policies to take?

People here are totally that pedantic - your Emancipation Proclamation example is a poor one as it didn't really do anything at the time - it was a big eye-roll for people back then. When they heard about it from the town crier most people made jack off motions with their left hand.

Don't take offense, now, I enjoy reading your thoughts and contributions. But we have to be specific - a law takes effect when it is actively enforced. And that varies a lot. It seems you're pointing more in the direction of economic policies or how unrelated policies change the economy over time. An excellent question - I think that larger trends take about five years to come to fruition. I have no basis for that, and of course government policy doesn't influence everything. But five years feels right.
