An Australian experience with tractor rollover protective structure rebate programs: process, impact and outcome evaluation.

The purpose of this study was to assess the effectiveness of the tractor rollover protective structure rebate program carried out by the Victorian Workcover Authority (Vic., Australia) in 1997-1998. The program was described using existing documents and records. Quantitative and qualitative information on tangible and intangible benefits were gathered through interviews with program applicants and other key informants. Information on the applicants and their tractors was obtained by analyzing the rebate application data. A cost-benefit analysis was conducted. The proportion of unprotected tractors was reduced from approximately 24%-7%. The program cost 7,886,067 Australian dollars ($AUD), which based on the projected prevention of 20 deaths over 10 years, equates to $AUD 290,668 per life saved. The lifetime cost per rollover death was estimated at $AUD 694,879 and $AUD 1,407,991 for the human capital and willingness to pay models, respectively. The success of the program is attributable to a range of factors, including legislative changes, publicity and awareness raising, and the financial incentive of the rebate. Benefits appear to outweigh any costs. Copyright 2003 Elsevier Ltd.
