You don't need anything to implement any policy. You just need someone with power to implement it. There's multiple ways of doing that. One way is to do so democratically, in which case you need to convince the population to vote for you. This can be done through religious means (I.e., appeals to a greater authority or set of morals) or -- ignoring metaphysical concerns -- evidentiary means (i.e., appeals to science and studies). The authors of this study are clearly trying to do the latter, because they want to convince you to vote for these policies.
The other way to implement it is to stage a coup, gain power by sheer force, and implement it that way.
In either case, you don't need an academic study.

Except money does grow on trees (and in supernovae and a few other places). Money is not a number in a database is a unit of net work owed by someone else to you. No work can be accomplished without sunlight and trees.
Money has to come from somewhere, because there's only so much work being done.
