Agent_Zero. Geoff’s work is so fantastic in this space. Cities, just like ecosystems, are more diverse as they get bigger. Why is that? Well, if you think about it from a biological perspective, there’s just more diversity carrying capacity, right? Like if I’m interested in European soccer and I live in a town of 500 people, there’s just no one to

Another, more intuitive way to understand urban scaling is the speed of life in cities. Life in larger cities is generally faster, meaning one can do more, both good and bad, by having more social exchanges over the same amount of time. This speed of social life is intimately connected to the spatial density of many activities, creating spaces and

Pour le physicien Yaneer Bar-Yam, spécialiste en science des systèmes et directeur du New England Complex Systems Institute de Cambridge (États-Unis), « une société en réseau se comporte comme un organisme multicellulaire217 » : la plupart des organes sont vitaux, on ne peut amputer une partie sans risquer la mort de l’organisme. Ce qu’a découvert

It traditionally assumed that firms were independent, and so changes would be independent, and so their sizes and aggregate effects would be distributed normally.

For example, economist George Steckel and anthropologist Jerome Rose (2002) examined health indicators for Prehispanic New World societies and found that the median health of individuals declined as societies grew more complex. This suggests social complexity emerges from mechanisms that promote coordinated behavior even if it is not in the best in

What’s really happening within each city is a massive exchange of information across social and economic networks of people and organizations, all taking place on a complex infrastructural landscape of buildings, roads, pipes, and wires. For the most part there is no maestro; the properties of cities emerge from countless interactions of millions o

One can define living beings as complex systems of limited size that are stable and that reproduce themselves.

As a new point of view we turn to bounded rationality, a departure from the mainstream tradition. We no longer can assume that every agent is a perfect calculator. This point of view is given a great deal of emphasis by Herbert Simon. Simon argued that people do not maximize. When they’re forecasting the future, they do not perform the task of rati
