Summary

This brief compiles analyses of several articles covering diverse topics, including the economic impact of land ownership and its financialization, the complexities of measuring union effects on wages, the business history and demise of FiveThirtyEight and data journalism, and open-source software as a defensive strategy. It also reviews agent-based market modeling for understanding bubbles, the impossibility of "perfect" economic modeling, and the rediscovery of forgotten financial technologies. Additionally, the brief includes a book review on Fidelity's rise in asset management, highlighting its strategies for capturing alpha, cultivating talent, and operational innovations like the 401(k). The content concludes with an open thread on data labeling and current job listings.
