OVERVIEW The analysis in this Technical Appendix considers two questions. How does the Boston metropolitan economy benefit from the availability of MBTA operations? Is there an economic penalty associated with allowing the system to fall out of a state of good repair? Or, put another way, would there be an economic gain to returning the system to a state of good repair? The report is not a cost-benefit analysis on the existence of MBTA, nor should its results be construed as such. Instead, it is designed to give multiple audiences a sense of transit’s role in the region by simply describing the variety of ways MBTA’s transit services impact the region. STUDY SCENARIOS To measure MBTA’s contribution to the economy of Metropolitan Boston, Three distinct scenarios were developed for the years 2015 and 2030, in addition to a Base Case or “Baseline”. The first scenario hypothetically removes all existing MBTA transit service. This “no MBTA” scenario is not the research objective,
