CEO-to-worker pay ratio in 1965: 20-1 CEO-to-worker pay ratio in 1990: 75-1 CEO-to-worker pay ratio today: 280-to-1 Trickle-down economics was always a sham. Nothing has ever trickled down.

Decomposition of Income Inequality by Subgroups openknowledge.fao.org/server/api/c...

Not all inequality measures were created equal The measurement of wealth inequality, its decompositions, and an application to European household wealth Rita Neves Costa, Sébastien Pérez-Duarte December 2019 www.ecb.europa.eu/pub/pdf/scps...

The 100 lowest-paying US corporations spent $644B on stock buybacks from 2019 to 2024. Buybacks artificially boost share prices and inflate CEO pay. The typical worker at these companies earned $35k last year. Meanwhile, the average CEO was paid $17.2M See the problem?

With zPlato you get an inequality measure which behaves quite similar to the Gini index. However, zPlato is much more sensitive to small groups of very poor people. That's not "woke" as it reflects a real risk: Already today's techologies provide horrible weapons to single frustrated individuals.

I just found a "The Plato Index", a measure of tax progressivity devised by Valpy FitzGerald, Oxford University and presented in 2006. www.taxjustice.net/cms/upload/p... I devised my Platon Inequality in 2004. Valpy FitzGerald and I probably both think that Plato was a wise man.

Symmetrizing the Theil-T redundancy. (With σ=0, it turns into the Hoover index.)

With zPlato you can present an inequality indicator in a ratio format. Example: In the case below zPlato of an assembly with 11 groups is 52%. There is an assembly with just two groups where in the 1st group 76% of people own 24% of all ressources, while in the 2nd group 24% of people own 76 %.

The two groups assembly and the eleven groups assembly have the same symmetrized Theil redundancy.

Kullback–Leibler (KL) divergence is a cornerstone of machine learning. We use it everywhere, from training classifiers and distilling knowledge from models, to learning generative models and aligning LLMs. BUT, what does it mean, and how do we (actually) compute it? Video: youtu.be/tXE23653JrU

20. @brankomilan.bsky.social calls the transition to the more modern form of inequality homoploutia: the top earners of wages are also often top earners of capital; in the 19th century, they weren't - wage and capital income correlated negatively, because if you have money, why work at all? /end

Just read @brankomilan.bsky.social's latest on income & compositional inequality. One more point: if AI pushes up the capital share by replacing jobs across skill levels, reducing compositional inequality can help capital complement labor—and prevent income inequality from rising👇

While capitalism rules alone, 85% of the (adult) people in the world have no income from property. New capitalism III: Capital Why is capital so concentrated and why so few have it? branko2f7.substack.com/p/the-new-ca...

IneqComps is the name of a program which I originally wrote just as an exercise in Haskell. The program computes inequality measures used as indicators for the inequality of resource distributions. The measures are symmetric, therefore they also are about the distribution of people to resources.

About 20 years ago I created (just using simple algebra and the Shannon entropy) an inequalty measure for myself to check the distribution of data transmission capacity to the carriers of OFDM modulated signals. Today I understand that what I did then looks like the Jensen–Shannon divergence.

As it currently stands, I'm calculating a measure's "score" based on the Jensen-Shannon distance between the two distributions (pitchtype and rest-of-repertoire). I also do this for release angles (with higher score = more similar).

When we measure this both using KL divergence (forward and reverse) and Jensen-Shannon divergence, all show that the posteriors are *more* different after seeing the same evidence than the priors. This isn't a cognitive bias of irrational actors—it's with Bayesian reasoning! 🤯

Yes, KL is very interesting, although its interpretation can be a bit unintuitive... Maybe the Jensen-Shannon divergence would be easier to use in applied contexts because it's easier to interpret, although I’m not sure if it has any disadvantages compared to KL... 🤷‍♂️🤷‍♂️🤷‍♂️

It seems that formula (1) also can be found as “Kullback-Leibler divergence” in publications on general entropy indices.

"The gini index for income in Norway is just 24.9 but the wealth gini is 80.5!" (Michael Roberts, thenextrecession.wordpress.com/2021/05/02/w...) As for income, that's probably for disposable income after redistribution through e.g. tax-transfer. The Gini for market income was around 40%.

Entropy measures used as inequality indicators are normalized redundancies of a system, where the measured system entropy is deducted from from the maximum entropy of the system.

Two experimental inequality measures: - zPlato - rAccept and zAccept The acceptance measure surely is disputable. #ResearchProposal #TheilIndex #TheilRedundancy #HooverInequality #HooverIndex #RobinHoodIndex #Gini #GiniIndex #GiniCoefficient #PlatoInequality #inequality See also ALT-text

Wie fair empfinden Menschen die Vermögensungleichheit? Das fragen sich @markusmarterbauer.bsky.social, @juliahofmann.bsky.social und ich in einem Artikel in der Fachzeitschrift "Review of Income and Wealth": doi.org/10.1111/roiw... (open access) Hier ein paar Blitzlichter aus unserem Beitrag 👇

About the Theil-T inequality and its inversion:

After rSym in [0,∞) has been computed, it can be converted into zSym in the interval [0,1] by zSym=1-exp(-rSym); that's the cumulative distribution function (CDF). The next step is to convert zSym to zPlato in [0,1].

Between c. 4200 and 3600 BC, the so-called Trypillia mega-sites were established on the northern limits of the Pontic Steppe. Researchers computed the Gini index for the inequality of housing aereas. "The overall Gini coefficient for all houses is 0.2385". www.cambridge.org/core/journal...
