This paper examines budget goal commitment and informational effects of budget participation on performance. A structural model is proposed and tested that includes budget participation, budget goal commitment, job-relevant information, and job performance variables. The data were collected by survey questionnaires. Seventy-nine middle-level managers, drawn randomly from a cross-section of manufacturing companies in Australia, participated in the project. A structural equation modeling technique was used to test hypothesized linkages. Support was found for the effects of budget goal commitment and informational roles of budget participation on job performance.
