Is there a consensus among economists on supply-side economics?
gpt
Supply is one part of the equation. Demand is another. Their relative elasticities tell you which will respond more strongly to a given exogenous shock, but to ignore either is to be missing a major part of the picture.

So... yes? And also no?

Edit: the honest answer is that used in the way you’re probably using it, it’s a political term pretending to be an economic one and it’s so trivial and poorly theorized that it falls in the not even economics” realm and is therefore not even a question that enjoys the consideration required for a consensus. The “tax cuts pay for themselves always” argument comes from the Laffer curve, which is simply a visualization of a trivial insight (that revenue at 0% and 100% is $0, therefore there is a revenue maximizing point somewhere in between), but definitively determining the shape of that curve and the location of that revenue maximizing point is impossible, at least with modern computing technology. Therefore to make any sweeping claim about the effect of, say, progressive taxes writ large with regard to revenue or even economic growth is inherently useless.
