The Tragedy of the Commons in Emergency Medical Services | Toshiaki Iizuka

In this webinar, the study co-author presents preliminary findings on a commons problem in the context of the emergency ambulance services in Tokyo. Emergency ambulance service is free in Japan, and no one is excluded from using it. Because capacity is limited, individually rational ambulance use may delay the use by others, lowering the chance of survival. The fire department urges the proper use of ambulances to save lives that can be saved, but little is known about the extent of the negative consumption externality. In this paper, the authors first estimate how one's ambulance use affects others with respect to arrival delays and survival rates. Then, they analyze the impact of potential remedies that alter non-excludability and rivalry in ambulance use.
