In a controlled scenario, government implement a measure, let’s say in year 2020 with a specific installation cost of some technologies. Every year, there is an add-on operation cost. These technologies have life time of 30 years. So, by the year 2035, all investment cost = installation cost + (2035-2020) * annual operation cost.
I estimated health benefit (i.e., mortality) of PM10 emissions reduction in year 2035 (between BAU and strengthen control measure). From my understanding, this is number of avoided mortality/specific year 2035.
I then also adopted VSL year 2015 (Thailand) from VSL (US EPA) and projected to year 2035.
Valuation now is a function of avoided mortality of specific year 2035 and VSL year 2035.
My question: In order to estimate cost-benefit of this measure, should I just compare health benefit in specific year 2035 to all investment cost up to year 2035? …considering that air benefit and heath benefit occurred every year since 2020 with implementation of new measure.
Thank you for your kind consideration and feedback in advance.
