Our goal was to develop integrated statistical models that consider not just the negative externalities (such as congestion effects) but also the positive externalities and benefits of increased usage.<\/p>\n<p><strong>WHAT WE FOUND<\/strong><br \/>\nOur comprehensive service management research program addressed tradeoffs between positive and negative effects, combining models from economics and operations research as well as engineering performance analysis.<\/p>\n<p>Our findings pointed to a unique optimal scale: a number of users at which the total efficiency of the system is maximized. At this optimal scale, the number of users participating is not so large as to create serious congestion, and not so small as to make the system worthless to the participants.<\/p>\n<p><strong>LEARN MORE<\/strong><br \/>\nJohari, R., &amp; Kumar, S.
