We analyze an extensive proprietary database of corporate social responsibility engagements with U.S. public companies from 1999-2009. Engagements address environmental, social, and governance concerns. Successful (unsuccessful) engagements are followed by positive (zero) abnormal returns. Companies with inferior governance and socially conscious institutional investors are more likely to be engaged. Success in engagements is more probable if the engaged firm has reputational concerns and higher capacity to implement changes. Collaboration among activists is instrumental in increasing the success rate of environmental/social engagements. After successful engagements, particularly on environmental/social issues, companies experience improved accounting performance and governance and increased institutional ownership.

The consensus view of the influential economist John Maynard Keynes is that he was a stellar investor. We provide an extensive quantitative appraisal of his performance over a quarter century and present detailed analysis of his archived trading records. His top-down approach initially generated disappointing returns with no evidence of any market-timing ability. However, from the early 1930s his performance improved as he evolved into a bottom-up stock picker with substantial active risk and pronounced size and value tilts. Our reconstruction of Keynes’s stock trading provides a unique record of realized performance and sheds light on how equity investing developed historically.

Using historical price records for Bordeaux Premiers Crus, we examine the impact of aging on wine prices and the long-term investment performance of fine wine. In line with the predictions of an illustrative model, young maturing wines from high-quality vintages provide the highest financial returns. Past maturity, famous châteaus deliver growing non-pecuniary benefits to their owners. Using an arithmetic repeat-sales regression over 1900–2012, we estimate a real financial return to wine investment (net of storage costs) of 4.1%, which exceeds bonds, art, and stamps. Returns to wine and equities are positively correlated. Finally, we find evidence of in-sample return predictability.
