Elroy Dimson on Rates of Return Since the Middle Ages, University Endowments, the Equity Risk Premium, and Wine

Elroy Dimson and Larry Siegel discuss the origins of long-term investing by medieval universities, then move to rates of return, both past and future, on stocks versus bonds – there are some surprises in the older data suggesting the equity risk premium may not be as high as it appears. Dimson recounts his involvement with long-term investors such as the Norwegian sovereign wealth fund, and presents lessons for the future. He concludes with “curiosity assets” such as wine, art, and postage stamps. (You should not invest in postage stamps.)
