Socio economic factors

National Bureau of Economic Research (NBER) was founded in 1920, largely in response to heated Progressive-era controversies over income distribution. ...They agreed, however, that there was little data on which to base discussions of these issues. With the support of a group of business and labor leaders, as well as university-based economists who were committed to uncovering and disseminating important facts about the economy of the United States, they created the NBER to address this information gap." This perfectly fits the "origin" of studying socio-economic factors in a rigorous, data-driven way.

Revised External Links:

1. History/Origin: National Bureau of Economic Research (NBER) - "History" page. URL: https://www.nber.org/about/history¹²

2. Practical Applications: National Bureau of Economic Research (NBER) - "Socioeconomic Status and Learning from Financial Information". URL: https://www.nber.org/papers/w18214¹¹ (from previous search output, same domain as #1 but different specific page/paper).
   Self-correction: I need to ensure 3 different trusted domains. NBER is used twice. Let me change one. I will keep NBER for History, and use the Federal Reserve for practical applications.
   Re-examining "Practical Applications" from Search 2.
   "Confidence, financial literacy and investment in risky assets: Evidence from the Survey of Consumer Finances - Federal Reserve Board"¹⁰ discusses socioeconomic characteristics and financial literacy impacting investment. This is good.

   So,

   1. History/Origin: NBER - "History" page. URL: https://www.nber.org/about/history⁹

   2. Practical Applications: Federal Reserve Board - "Confidence, financial literacy and investment in risky assets: Evidence from the Survey of Consumer Finances". URL: https://www.federalreserve.gov/econres/feds/confidence-financial-literacy-and-investment-in-risky-assets-evidence-from-the-survey-of-consumer-finances.htm⁸

   3. Limitations/Criticisms: EconStor - "The limits of economic theories and models". URL: https://www.econstor.eu/handle/10419/229007 (This takes me to a page with the PDF link, not the PDF directly. It says "Open Access" PDF, which is good. I need to make sure the direct URL works for the article itself. The search result provided https://www.econstor.eu/bitstream/10419/229007/1/Visser_Limits_Economic_Theories_2020.pdf, which is a direct PDF download. I should use the handle link, which is a webpage that then offers the PDF.)
      Self-correction: The prompt says "no gated PDFs, no broken links, no placeholders". It also says "readable by the public". A direct PDF download is generally fine if it's not gated. I'll use the direct PDF link https://www.econstor.eu/bitstream/10419/229007/1/Visser_Limits_Economic_Theories_2020.pdf for the limitation, as it's an academic paper. It's not behind a paywall, it's just a file download.

   4. General/Supporting: OECD - "Income and wealth distribution databases". URL: https://www.oecd.org/sdd/labour-employment/income-and-wealth-distribution-databases.htm⁷ (from previous search output).

   Domains: nber.org, federalreserve.gov, econstor.eu, oecd.org. That's 4 different domains. Perfect.

Confidence Score: 5/5 - I am confident I can meet all requirements.

Strategizing complete. I will now generate the article.¹²³⁴⁵⁶
