Regulation tells institutions what they must do. It rarely tells them what they will choose to do once the rules change — and that gap is where the more interesting behaviour shows up.
When a pension system changes its rules — a new fee cap, a new default option, a new competition mechanism — most commentary focuses on what the reform says on paper. Far less attention goes to what the reform changes in practice: how a fund manager reprices risk, how a board reallocates a marketing budget, how a member's inertia gets exploited or protected by the new default.
Rules versus incentives
A rule is a constraint. An incentive is a reason. Two institutions facing the identical constraint can respond in opposite ways depending on what they're incentivised to optimise for — asset growth, member retention, short-term performance, or long-term outcomes. Reform design that ignores this gap tends to produce compliance without the intended behavioural shift.
Markets are shaped not only by rules, but by the incentives those rules create.
Where this shows up in Chile and Australia
Chile's AFP system and Australia's superannuation system have both gone through rounds of reform aimed at improving member outcomes and sharpening competition. In both markets, some of the most consequential effects came not from the headline rule, but from a secondary incentive the rule created — for managers, for intermediaries, and for the institutions distributing products to members.
Understanding this gap is, in our view, more useful to an investment committee or a policy team than a summary of the regulation itself. It's also the lens we bring to every engagement: not just what changed, but who now has a reason to behave differently.
