Rostworowski devotes significant attention to the Inca economy, which was characterized by a unique blend of reciprocity, redistribution, and market exchange. The Incas developed a system of reciprocal labor, known as mita, which required subjects to provide labor for the state in exchange for food, clothing, and other essential goods. The empire also controlled a vast network of roads, trails, and storehouses, which facilitated the exchange of goods and information across long distances.
