In fact that there's both a liberal and conservative economics ideology, and what could form a scientific discipline in between is unfortunately cornered and sorely lacking visibility.
The distinction between liberal and conservative political labeling in america is entirely cultural. There is precisely zero ideological, ie political-economic, difference. It's just culture wars all the way down while we get pickpocketed together.
I see what you mean, but I'd disagree with the idea that there's “precisely zero ideological, ie political-economic, difference”.
That's true that since at least Clinton, the Democrats as a political party have mostly embraced the business-friendly view that is also the conservatives' position on the subject.
But the Democrat's leadership are only a (very) imperfect mirror of their electorate and of the intellectual left, and there is definitely a significant set of left-wing economists (Polanyi, Stiglitz, Piketti to name a few of the most prominent, in chronological order).
You can't look at Cochrane and Piketti and say there's no progressive vs conservatives divide in economics.
I was being deliberately facetious, I suppose, but because of our campaign finance problems any policy of major economic import has coordinated bipartisan pressure.
