As is shown in the graph below, according to the law of supply, decreasing the supply of a product shifts the supply curve up and left (from supply curve 1 to 2), therefore, changing the equilibrium point (from E1 to E2) and increasing the price of the product (P1 to P2) [Michael Parkin et al.; 2010].

One of the goals of the cartel is to keep a monopoly position that is resilient [Ivona Vogelsang; 2005]. The Oxford Dictionary defines a monopoly as “the exclusive possession or control of the s...
