Jemisin, N.K. The Fifth Season.

There is economics woven into Jemisin's worldbuilding, although perhaps what's more interesting is the allegorical exploration of cycles and stability, social, economic, and ecological.

The hereditary "use-castes" also offer a somewhat usefully estranging division of labour. It is not always precisely clear whether an attribution is a whole use-caste, or rather a specialism within a use-caste. For example, Strongback, Resistant, Breeder, Innovator, and Leadership are definitely use-castes (the first four mentioned as being among the seven most common), but I'm a bit less sure about Hunter, Knapper, Geomest, and Geneer, and even Guardian and Orogene. Here's

"Those who distinguish themselves may be permitted to bear their mother’s use-caste at comm-naming" -- this is open to interpretation. Is it perhaps describing a limited form of social mobility, whereby by default every child is of their father's caste, but those who demonstrate potential in their mother's caste may switch?

The Broken Earth sequence shows resonance with and/or the influence of political theory around the state of the exception (Agamben, Schmitt, Mouffe, etc.). There are also strong (neo-)Malthussian currents running through it.
