Bigger cities are associated with higher per-capita productivity — in positive aspects, such as inventions, and negative ones, such as crimes. A difficulty in understanding the origin of this phenomenon, superlinear scaling, is that similar quantities exhibit different scaling behaviors. We develop a first-principles formulation for the origin of superlinear scaling that also explains these differences. Our model suggests that superlinear scaling can be an outcome of the increased likelihood of finding required collaborations in a larger, interconnected population, and that activities requiring more participants will exhibit more pronounced superlinear scaling. We test this model using a novel dataset for group sizes involved in seven types of crimes, as well as patents, and find strong support.
