I think Buffett and Munger invented an amazing Behavioral Finance Formula or Process that is underappreciated by the business and academic communities. On paper as early as the 1977 BRK annual letter, their work in designing a mixed qualitative + quantitative formula may be worthy of a Nobel Prize in Economics and Behavioral Finance. So, in my new self-published book "The Four Filters Invention of Warren Buffett and Charlie Munger" ( www.frips.com ) I examine each of the basic steps they perform in "framing and making" an investment decision. I made this book a small and focused look into this amazing invention within "Behavioral Finance."Buffett mentions the Four Filters this way: "Charlie and I look for companies that have a) a business we understand; b) favorable long-term economics; c) able and trustworthy management; and d) a sensible price tag."
In my view, the genius of Buffett and Munger's four filters process was to "capture all the important stakeholders" in one "multi-variable" equation. Imagine...Products, Enduring Customers, Managers, and Margin-of-Safety... all the important stakeholders for business success in one mixed "qual + quant" formula...The genius of the Munger and Buffett collaboration. And, quality bargains at 50 cents on the dollar may soon appear; Use the Four Filters!
