Measures of wealth and production have been found to scale superlinearly withthe population of a city. Therefore, it makes economic sense for humans tocongregate together in dense settlements. A recent model of population dynamicsshowed that population growth can become superexponential due to thesuperlinear scaling of production with population in a city. Here, wegeneralize this population dynamics model and demonstrate the existence ofmultiple stable equilibrium points, showing how population growth can bestymied by a poor economic environment. This occurs when the goods and servicesproduced by the city become less profitable due to a lack of diversification inthe city's economy. Then, relying on critical slowing down signals related tothe stability of an equilibrium point, we present an algorithm for engineeringregime shifts such that a city at a stable equilibrium point may continue togrow again. The generality of the model and the algorithm used here impliesthat the model and algorithm need not be restricted to urban systems; they areeasily applicable to other types of systems where the assumptions used arevalid.
