Investing: The Last Liberal Art

I have recently read Investing: The Last Liberal Art. In it, Robert Hagstrom argues that students, investors and investment professionals need a range or latticework of mental models to help them understand the complex world of investment. The mental models come from a wide range of disciplines - mathematics, psychology, philosophy, sociology, biology, decision making, literature and physics. Hagstrom clearly demonstrates how each of these disciplines can help investors think about investing.

I found this book very helpful in thinking about the education of students in my school. The world is a very complex place and we need to have a diversified portfolio of ways of thinking about the world, which only a broad-based education gives us. The university curriculum can become too specialised and narrow, resulting in graduates with an undiversified portfolio of mental models.

This bank was only the 35th largest bank in Germany at the time so why would anyone be interested in studying its failure? Herstatt failed because of its involvement in risky foreign exchange business. When it closed its doors on 26 June 1974, counterparty banks (mainly in New York) had not received dollars due to them because of time-zone differences - this is known as settlement risk. The cross-jurisdictional implications of its failure resulted in the Bank for International Settlements setting up the Basel Committee on Banking Supervision and Herstatt's failure was a key reason for the establishment of real-time gross settlements systems, which ensures that payments between two banks are executed in real time. The Bank of England's Ben Norman has an interesting post on Herstatt over at the Bank's new blog ( Bank Underground ). As well as giving an excellent overview of
