The Prevention Cycle: State Investments in Preventing System Risks over Time

The policy drivers for preventing system risks – risks that threaten vital parts of society – represent an as-yet understudied subject. A fundamental characteristic of an effective prevention policy for system risks is long-term investment. This article presents evidence that long-term investment in prevention follows a cyclical rather than a stable pattern, which implies large costs to the welfare of future generations. This cycle is usually triggered by a shock that shifts the set of preventive policies that are acceptable to or even demanded by society. After a rapid rise in preventive investment, however, attention often wanes, and the downturn of the prevention cycle sets in. While policy shocks from crises and disasters are commonly studied, their policy legacies rarely have been. This article offers a theoretical framework for this “prevention cycle”, demonstrates its applicability in understanding policy investment in several system risks and offers suggestions for its fundamental causes.
