A paper by University of Toronto researchers Alexander Dyck and Lukasz Pomorski found the largest pension funds — averaging $37-billion in assets — outperformed smaller plans — averaging $1-billion in assets — by 43 to 50 basis points annually. “Bigger is better when it comes to pension plans,” the paper concludes.
Why do big plans do better? One reason is that they are more likely to be internally managed, which means their assets are managed by in-house staff rather than by outside private sector money managers. Large plans manage 13 times more of their active assets internally compared to the smallest tier, the paper says. The study says between one-third and one-half of the gains come from cost savings related to internal management, where costs are at least three times lower than under external management.
The data for the study comes from Toronto-based CEM Benchmarking Inc., which maintains a database of financial returns between 1990 and 2008 for 842 pension plans around the world, including U.S., Canadian, European, Australian and New Zealand funds.
