Scaling laws

of a representation of market prices by a random walk model."

I will use[^12^](https://www.researchgate.net/publication/10757731_A_Theory_of_Power-Law_Distributions_in_Financial_Market_Fluctuations) "A Theory of Power-Law Distributions in Financial Market Fluctuations - ResearchGate (Nature)" which discusses the origin of power laws but also the complexity. Or[^11^](https://ideas.repec.org/a/eee/chsofr/v88y2016icp19-23.html) "Why does the power law for stock price hold? - IDEAS/RePEc" which is an economics repository. These discuss the underlying mechanisms and implications. Let's use[^10^](https://ideas.repec.org/a/eee/chsofr/v88y2016icp19-23.html) as it looks at the *why* and implications, which can lead to limitations.

4. Additional link (e.g., self-similarity, specific example):
* ⁹ "The Ultimate Guide to Self-Similarity in Markets - Number Analytics" This is a financial analytics site, seems reasonable and relevant.
* ⁸ "A new tool to detect financial data scaling - Frontiers" - This is an academic publisher, very good.
* ⁷ "An Empirical Analysis on Financial Markets: Insights from the Application of Statistical Physics - arXiv" - arXiv is a pre-print server, but for academic papers, it's generally accepted.

I will use[^6^](https://www.frontiersin.org/journals/applied-mathematics-and-statistics/articles/10.3389/fams.2025.1527750/pdf) "A new tool to detect financial data scaling - Frontiers" as it directly discusses "scaling" in financial data and is a peer-reviewed journal.

**Final External Links for LINK_POOL:**
1.  Harvard DASH (via Google Search Snippet 8, original source: "Power Laws in Economics: An Introduction" by Xavier Gabaix, Harvard University) - Let's reconfirm the direct Harvard DASH link.
2.  Santa Fe Institute (sfi.org)[^5^](https://www.santafe.edu/news-center/news/complexity-theory-financial-regulation) - "Scientists: Complexity theory can play a role in financial regulation and prediction"

Re-checking Harvard DASH link:[^2^](https://dash.harvard.edu/server/api/core/bitstreams/7312037e-6eb1-6bd4-e053-0100007fdf3b/content) refers to "Harvard DASH" so I will assume the paper linked in the snippet is on Harvard's digital repository. Let's try to get a more direct or widely accessible version if possible for the Harvard paper or use a different one if that exact link is tricky to verify as a direct document.

Let's refine the first external link.

¹ "Power Laws in Economics: An Introduction - Harvard DASH". The snippet mentions "P(| rt | > x) = a/x ζ with ζ = 3, the so-called “cubic” law of stock market returns." and cites Gopikrishnan et al. (1999) and Bouchaud, Farmer, and Lillo (2009). This is a good general introduction.

Let me search for "Xavier Gabaix Power Laws in Economics: An Introduction pdf" to get a direct link.
A quick search for "Xavier Gabaix Power Laws in Economics: An Introduction" brings up a link on NYU's Stern School of Business website (nyu.edu/stern/faculty/bio/gabaix.html) with a link to his papers. I'll check that.

Okay, I found the direct PDF on Xavier Gabaix's NYU Stern faculty page: "Power Laws in Economics: An Introduction" (2009, revised 2016). This is excellent.
