Kurtz, Lloyd and Chris Luck. "Investment Returns of The 100 Best Companies to Work for in America", Working paper, 1999.

Compares the performance of the publicly traded companies named in the book The 100 Best Companies to Work for in America with the S&P 500 for the 1985-1999 time period. Finds that the market-weighted list outperforms the market-weighted S&P 500, and the equal-weighted list outperforms the equal-weighted S&P 500. An analysis of returns using the BARRA performance attribution model gives a statistically significant annual stock selection benefit of approximately 1.6% for each portfolio. This residual appears related to the publication dates of the book and lists in Fortune magazine.
