Science fiction that takes economics seriously is vanishingly rare. Most SF uses economics as backdrop — a premise about resource scarcity or abundance that motivates the plot but isn't itself examined. The Dispossessed by Le Guin is the great exception: it takes economics seriously enough that the two societies' different economic arrangements are the actual subject of the novel.

Kim Stanley Robinson is the other exception. The Mars trilogy is explicitly about the economics of terraforming — who owns a planet, what property rights mean in the absence of pre-existing law, how a society organizes distribution when the resources are essentially infinite but access is constrained. These are not questions that most SF asks, and Robinson earns their difficulty.

I recommend both to readers who think economics is not a literary subject. Economics is about how humans organize access to the things they need. That's deeply literary.
