Peter Bernstein's Economist on Wall Street is a collection of work from 1955 to 1970. The audio is especially interesting because so many of Bernstein's observations reflect the most important issues of the present - the outlook for inflation and its control, the intricacies of monetary policy, the future of the dollar, and the dilemmas of household finances. Bernstein was also concerned with developments in portfolio management, including the new influence of institutional investors and rules for optimal asset mixes. He provides light touches, too, as he indulges in fantasies and philosophical musings over a wide variety of topics.

With so many years of hindsight, we should not be surprised to find some of Bernstein's predictions running awry. But why? In each instance, these forecasts were biased by memories of the past. There is a big lesson to be learned there.
