"What can machine learning do for (social) scientific analysis, and what can it do to it? A contribution to the emerging debate on the role of machine learning for the social sciences, this article offers an introduction to this class of statistical techniques. It details its premises, logic, and the challenges it faces. This is done by comparing machine learning to more classical approaches to quantification – most notably parametric regression– both at a general level and in practice. The article is thus an intervention in the contentious debates about the role and possible consequences of adopting statistical learning in science. We claim that the revolution announced by many and feared by others will not happen any time soon, at least not in the terms that both proponents and critics of the technique have spelled out. The growing use of machine learning is not so much ushering in a radically new quantitative era as it is fostering an increased competition between the newly termed classic method and the learning approach. This, in turn, results in more uncertainty with respect to quantified results. Surprisingly enough, this may be good news for knowledge overall."

--- The correct line here is that 90%+ of "machine learning" is rebranded non-parametric regression, which is what the social sciences should have been doing all along anyway, because they have no good theories which suggest particular parametric forms. (Partial exceptions: demography and epidemiology.) If the resulting confidence sets are bigger than they'd like, that's still the actual range of uncertainty they need to live with, until they can reduce it with more and better empirical information, or additional constraints from well-supported theories. (Arguably, this was all in Haavelmo.) I look forward to seeing whether this paper grasps these obvious truths.

High-end art is one of the most manipulated markets in the world — Quartz
The nature of art as a commodity inherently makes efficient prices, meaning prices that reflect all available information about value, impossible. Value is subjective; the intrinsic value of a painting is paint and canvas—beyond that value is often a matter of taste.

This is why the industry has developed an intricate signaling process where the approval of a handful of galleries, collectors and museums, determines what is good and valuable. Dealers who own and work at art galleries invest many resources in building the artist’s brand.

But artists often take years to mature and have uneven periods, so any perception that an artist is over-hyped or overpriced can be anathema to his career. Value in art can be arbitrary but brands are fragile.

Machine learning fundamentals via linear regression
finally, a gentle one-sentence description of gradient descent in ML
Gradient descent enables a model to learn the gradient or direction that the model should take in order to reduce errors (differences between actual y and predicted y).

I tweet with the best of them, and I like reading the hard stuff. I have a phone filled with novels, even some experimental ones. But the reality is that the most profound feeling of cultural participation for me comes from trawling databases.

Wealth and Secular Stagnation: The Role of Industrial Organization and Intellectual Property Rights: RSF: Vol 2, No 6
"Changes in firm strategy and structure partially explain the sources and consequences of rising wealth inequality in America. Combining use of state-created monopolies around intellectual property rights (IPRs) for profitability and firm-level strategies to transform their industrial organization by pushing physical capital and noncore labor outside the boundaries of the firm leads to rising levels of wealth and income inequality among firms as well as individuals. Income inequality among firms in turn reduces growth in productive investment and thus in aggregate demand. Slower growth reflexively deters firms from new investment, aggravating the shortfall in aggregate demand. Decreased protection for IPRs and increased protection for subcontracted workers would help increase aggregate demand and thus push growth back to its prior level, as well as reducing wealth and income inequality among individuals."

This is awesome. (But it's also completely compatible with causal inference!) Also, the cultural references will probably require footnotes in just 10 years.
