Russia and Qatar Made the First Serious Moves in October

Russia and Qatar made the first serious moves in October 2008 toward forming an OPEC-style cartel on natural gas. The two strategies these countries face are to comply with the cartel agreement or to cheat on the cartel agreement. If all countries comply, the economic profit for both will be $140 million. If one country cheats, that country earns $200 million in economic profit and the other country has an economic loss of $10 million. If all countries cheat, they break even. What is the the likely outcome of this game if it is repeated as a tit-for-tat game?

A) If there are periods of cheating and colluding, then the countries' profits will be more than if they always colluded.
B) If the countries never collude, the outcome will be the monopoly outcome.
C) The countries will collude.
D) If the countries always collude, the outcome will be the perfectly competitive outcome.
