Reaganomics is a catchphrase given to the theory you described to make economics palatable to Republicans; they spout it all the time in arguments to try to make themselves look like they actually know what they're talking about.
It hasn't worked yet.
Technically, the ideas were brought about during the Nixon administration, but Reagan's administration implemented it more widespread. I'd somehow doubt that they'd like to have such a thing attributed to Nixon, though.
Thus the term "Reagan Hood" (robs from the poor, gives to the rich).
