We study how investment fees vary within private equity funds. Net‐of‐fee return clustering suggests that most funds have two tiers of fees, and we decompose differences across tiers into both management‐ and performance‐based fees. Managers of venture capital funds and those in high demand are less likely to use multiple fee schedules. Some investors consistently pay lower fees relative to others within their funds. Investor size, experience, and past performance explain some but not all of this effect, suggesting that unobserved traits like negotiation skill or bargaining power materially impact the fees that investors pay to access private markets.

Bank capital requirements are based on book values, which are slow to reflect losses. In this article, we develop a dynamic model of banks to study the interaction of regulation and delayed accounting. Our model explains four stylized facts: book and market values diverge during crises, the market-to-book ratio predicts future profitability, book leverage constraints rarely bind strictly even as market leverage fans out during crises, and banks delever gradually after net-worth shocks. We show how delayed accounting can allow the regulator to achieve better outcomes than immediate (mark-to-market) accounting. In an estimated version of the model, the optimal regulation couples faster loan-loss recognition with a modest relaxation of the book leverage constraint.
