|content=So my model is that Economics really changed. The old guys who did the most to lay the foundations were a lot less high on their own supply. They welcomed interactions with other disciplines. It feels like the 1970s transformed economics into something less intellectually honest.

|content=“None of the usual criteria that **real** experts use says that we are in a recession.” - Prof. @paulkrugman
Have you dealt w/ economics professionally as an academic from another field? If not, it’s exactly like this: “Reason, fact, analysis, total bullshit, fact, a lie, fact.”

|content=In fact the truths, insights, facts, analysis, etc. are pretty compelling. And they are the majority of what economists circulate.
And then the conversation turns, and out comes the superior dismissive insufferable gaslighting.
And you think: “Why ruin analysis with psychosis?”

|content=I was lucky enough as a younger man to get to know [[Ken Arrow]] and [[Paul Samuelson]] slightly. They didn’t have this trait. Talking to [[Ken Arrow|Arrow]] or [[Paul Samuelson|Samuelson]] was like talking to a research mathematician, biologist or physicist at the time. It wasn’t switching between reality & propoganda.

|content=Great question. Inflation is SUPPOSED to be a group valued field. In the case of bilateral trade it’s an element of GL(2,R) although the economists haven’t gotten there yet. But it is mostly not a field on Geography. It’s a field on path, Loop, preference and geographic spaces.

|content=Q1: Why is it a field on Preferences?
A1: Because a true COLA is not an index on baskets (mechanical index) but on welfare derived from baskets (economic index). BLS misrepresents [[CPI]] being COLA-driven abusing work of Erwin Diewert on Superlative indices. A COLA prices WELFARE.

|content=Q2: Why is inflation a field on LOOP spaces of preferences?
A2: Tastes are seasonal. In USA “We never spill Egg Nog on our bikinis.” What you both want & price HAS to be made seasonal to avoid the Cycling Problem (Holonomy) in index number thy. So we have LOOPS of tastes/prices.

|content=A2 Continued: If you don’t make loops of tastes and prices, you will show meaningless regular inflation if prices, quantities and tastes Circle back to their initial Jan 1 values. This confuses economic experts (Like Diewert) when it comes to chain/path indices…which is up next.

|content=Q3: Why is inflation a field on Path Spaces of Looped Preferences/Prices?
A3: Loosely, Index number theory really died w/ work of Ragnar Frisch (rightly) destroying Irving Fischer’s misguided work on axiomatic tests for bilateral (2 period) mechanical index numbers. Here’s why.

|content=A3 Cont.: As [[Ken Arrow]] challenged us “Frisch showed we can’t solve the bilateral index problem because a single agent at multiple points in time is *exactly* dual to multiple agents at a single instant of time. Which is exactly my ‘Impossibility Theorem’ in Social Choice. QED.”

|content=A3 Cont.: Our response: “Ah. That would be true but for 2 differences! First, Indices live in markets with *prices*. Our methods *don’t* live in social choice voting paradigms. Second, agents evolve into their future selves via paths. There’s no ‘morphing path’ in social choice.”

But Zoe doesn’t become Cam morphing into Fatima when voting. So parallel transport is unavailable. Even in topological social choice.”

|content=Q4: Why do you say indexes are Group-Valued? Isn’t inflation just a number?
A4: Here goes. In the most famous case you *can* get away with a number. But that 8.9% style [[CPI]] nonsense is actually secretly a 1x1 matrix in GL(1,R). And that actually matters! Why? B/c Non-linearity.

|content=A4 Cont.: Only 1x1 matrices commute. NxN matrices do not! And if A.B isn’t B.A, the system goes non-linear. So if you have 2 countries with 2 currencies, the commutative case doesn’t work at all. You need to use Freeman Dyson’s system of Time Ordered Products to save inflation.

|content=A4 Cont.: But even in the case of one Currency like the Dollar, economists don’t get the group issue. True COLAs are valued in an *infinite* dimensional non-commutative group called DIFF_0(R^+) equivalent to increasing differentiable functions from 0–>♾ reparameterizing ‘Utils’.

|content=Q5: So let’s see. Inflation is a field like temperature. But a field in a fiber bundle over ♾-dimensional path spaces of loops of preferences/prices valued in non-commuting groups leading to non linearities not addressed by economists? What about actual geography!”
A5: Fair. 👍

Just try to understand my bewilderment when @BLS_gov says 7.9% and everyone pretends that they aren’t really raising taxes & slashing social security. You’re being screwed.

|content=[[François Divisia]] or [[Ken Arrow]] or [[Paul Samuelson]] or Satoshi or [[Ronald Coase]] etc.... would be easy to defend.
But Graciela Chichilnisky or Bert Balk would be more interesting offbeat choices I could defend. I don't think they got their due for what is coming in mathematical econ.
