Cover Story: The two graphs illustrate the evolution of population and wealth near two steady points discussed in our study. These graphs focus on two key variables, population and wealth, plotting their trajectories in a two-dimensional space. The first graph depicts a stable point, where the dynamics gradually guide the system towards equilibrium. Conversely, the second graph shows an unstable point, with dynamics indicating a divergence from this state. The starting points are marked by small circles, while the steady states are indicated by a small star. View this paper
