The article explores how economic growth, changes in preferences, and inequality in income and wealth are connected in a diverse economy. The researchers use a mix of two economic theories to create a model that shows how these factors interact over time. They find that the economy's movement can be described by a set of complex equations, and they focus on how the economy transitions and reaches a stable state. By simulating the economy with different groups, they discover that habits of one group can impact the entire economic system's dynamics.
