Incrementalism as a decision theory about budget‐making is empirically evaluated by post‐war data within the framework of budget‐making processes of some Swedish public authorities. The analysis focuses on the relevance of a structural stability hypothesis using models for the processes of budget requests and appropriations. This hypothesis is tested by CUSUM and CUSUMQ tests. The more powerful CUSUMQ test clearly indicates a rejection of the stability assumption, which implies a need for revised models based on variability assumptions. These alternative models describing budget‐making processes are estimated by Kalman filtering, an estimation approach designed to allow for structural variability. The paper shows that the key decision principles of incrementalism are too crude for the understanding of budget decisions.
