Breifly, effort values are earned by a pokémon for each pokémon defeated, similar to experience. Before R/S, the formula was that a number equal to the defeated pokémon's base values was added to each of the winner's individual characteristic effort values (Special Attack adding to the Special one in GSC). The end effect on the current stat formula is a bonus point or two every few levels over a wild pokémon with the same individual values.

This seems to have changed radically for ruby/sapphire, but the exact effects are not precisely known. It does seem that there is an overall cap on the effort values allowed for all 6 stats now, in addition to the old cap for each one. On the other hand, it appears that only one stat earns effort for each battle, based on the opponent's best base stat, in which case it will mean trainers will need to be more selective when training their pokémon.

I think Pokemon Elite 2000 has a section on GSC effort and the stats formula as well:
