Blade Runner the film has remarkably little economics in it, it's more of a post-colonial treatment: some runaway slaves from the colonies have escaped back to the motherland, where they are subjected to pseudo-scientific tests to deem them subhuman so they can be executed.

The original PKD novel is much stranger and explicitly mentions a World War Three which has made a large number of animal species extinct. It's much more focused on the questions of mechanical substitutes for emotional relationships and the affect on the self.
