Scale Economies, Bargaining Power, and Investment Performance: Evidence from Pension Plans

By Tjeerd de Vries, S. Yanki Kalfa, Allan Timmermann & Russ Wermers

We explore the relation between the size of a defined benefit pension plan and its choice of active vs. passive management, internal vs. external management, and public vs. private markets. We find positive scale economies in pension plan investments; large plans have stronger bargaining power over their external managers in negotiating fees as well as having access to higher (pre-fee)-performing funds, relative to small plans. Using matching estimators, we find that internal management is associated with significantly lower costs than external management, reinforcing the enhanced bargaining power of large pension plans that have fixed-cost advantages in setting up internal management.
