Terskelregler

Terskelregler (threshold rules) are regulatory mechanisms in which a rule comes into effect only after a measured indicator crosses a predetermined level. They are used to balance precision and simplicity by avoiding continuous adjustments and focusing enforcement or benefits on cases that meet specific conditions.

These rules appear across public policy, welfare systems, taxation, environmental regulation, and administrative enforcement. Examples include eligibility thresholds for social benefits (income or asset limits that determine entitlement), emission or pollution thresholds that trigger penalties or controls, and tax brackets or benefit phaseouts that change as income or other indicators cross set values. In digital platforms, threshold rules can govern moderation or feature access, such as actions triggered when a report count reaches a certain number.

Advantages of terskelregler include greater predictability, transparency, and reduced administrative burden, since decisions hinge on a single observable metric rather than continuous assessment. Disadvantages include cliff effects near thresholds, potential unfairness for those just below the cutoff, and incentive effects or gaming where actors manipulate measurements. Thresholds can also be sensitive to measurement error and inflation, requiring regular adjustment or indexing.

Types of thresholds can be numeric, relative (percentage-based), fixed or dynamic (indexed for inflation or other changes). They may be hard thresholds (automatic triggering) or soft thresholds (discretionary review around the cutoff). Understanding how thresholds influence behavior and outcomes is central to designing effective and equitable regulatory systems.
