A lot of other models closely resemble economics:

- Computational systems, distributed systems, and operating system theory model resources and demand. They often attribute a cost to units of space, time, or compute based on availability.

- Ecological systems very closely model economics with respect to predator-prey dynamics.

- There are so many systems in biology that resemble economics. Evolutionary systems often increase gene dosage over generations in order to meet demand for gene products: polyploidity in plants, gene duplication, promoter amplification, etc. There are then also suppressive measures taken when deleterious effects arise. The balance of telomerase, etc. Within a living organism, there are the dynamics of apoptosis and proliferation pathways to follow the developmental program, to avoid disease states, etc. And then there are the biochemical flux of metabolites, etc.
