What were the similarities and differences of monopolies cartels and trusts?

Monopolies, cartels, and trusts are all forms of market control aimed at reducing competition and increasing profits. Monopolies occur when a single entity dominates an entire market, while cartels consist of multiple independent firms that collaborate to set prices and limit production. Trusts are similar to cartels but often involve the consolidation of companies into a single entity to exert greater control over a market. While all three aim to restrict competition, monopolies do so through singular dominance, whereas cartels and trusts involve cooperation among multiple businesses.
