The Dark Side of Social Networks

There is a blackly intriguing new paper out from Stanford GSB researcher Camelia Kuhnen that uses a novel data data set from the mutual fund industry to look at a dark side of social networks: the effect of such things on compensation, hiring, and performance. The results are worth reading:

  • Fund boards award portfolio management contracts preferentially to advisory firms which have had more business relationships with the funds’ directors. A one-standard deviation increase in connections between directors and a candidate advisor increases the odds that the candidate is chosen by 16%.
  • When advisory firms create new funds they offer board seats preferentially to directors known from past business relationships. Increasing connections by one standard deviation corresponds to a 28% increase in the odds of a candidate director being nominated.
  • Advisors receive higher pay when they are more connected to the fund directors. A one standard deviation increase in connections translates into more than $1 billion increase in transfers from mutual fund investors to advisory firms each year.
  • The preferential hiring and pay of connected advisors is not compensated by higher performance. A one standard deviation increase in connections corresponds to a decrease in fund returns (before and after advisory fees) and fund alphas
    of 1% per year.

      …I wonder if there are potential confounding variables related to personality type – as the personality attributes of managers who hire their friends would be the same ones missing from the psychopaths who seem to make better than average investment decisions.
