please use the economics books called IB DIPLOMA PROGRAMME ECONOMICS COURSE COMPANIONBY Jocelyn Blink and Ian Dorton. oxford edition. use chapter 10 that is related to Oligopoly”
please use footnotes and cite all the sources.
Use oficial websites. For example, not wikipedia.

these are some outlines that could help you:

IV. Agreements between cartels to reduce competition
V. The agreements between the cartels to increase profits
VI. Alternative strategies to increase the price of the product
Government corruption

but you can find more outlines or organize it better.

one of the basic points is how cartels collide or cooperate each other to reduce competition and increase profits. there are some graphs in the book such as figure 10.2 in chapter 10.

If you could use some spanish sources it would be even better.

use diagrams and maps
