b) Efficiency Analysis You now need to consider the efficiency analysis. Due to taxes, duties, and subsidies we are required to calculate the relevant shadow prices for the following: Input Item Efficiency Price Information Taxes: - Building 15% - Furniture 10% - Paper & Stationary 10% Duties: - Vehicles 20% Subsidies: - Computers 20% - Educational Materials 35% - Utilities and Internet 15% It is also noted that land has an opportunity cost of $0 and the opportunity cost of labour is 50% of the market wage for casual labour. The social worker, team manager, and court advocacy workers are employed from elsewhere and should be costed at the market wage. You also note that financial exploitation many hidden costs to society. There are many external benefits you can account for in this project including improvements in quality of life, confidence to live independently, and reduced need for social care service interventions. However, after some research you determined that the one most important external benefit your team would like to capture in this CBA is the reduction in costs to the health care sector. To estimate this, you determined the following information was essential for your analysis: The population of persons over the age of 60 in 2019 was 800,000. The cost of admission of those aged over 60 into a hospital is $3,622 per admission. 2.6% of older adults experience some form of mistreatment or financial exploitation. If the efficacy of the intervention means 8% of the older adult population are longer admitted to a hospital the net external benefit can be identified as
