Asset Pricing and Risk‐Sharing Implications of Alternative Pension Plan Systems
The Journal of Finance, Volume 81, Issue 1, Page 143-188, February 2026.ABSTRACT We show that incorporating defined benefit pension funds in an incomplete markets asset pricing model improves its ability to match the historical equity premium and riskless rate and has important risk‐sharing implications. We document the importance of the pension fund's size and asset demands, and a new risk channel arising from ...
