Cooperation, co-operation, or coöperation is the process of working or acting together, which can be accomplished by both intentional and non-intentional agents. In its simplest form it involves things working in harmony, side by side, while in its more complicated forms, it can involve something as complex as the inner workings of a human being or even the social patterns of a nation. It is the alternative to working separately in competition. Cooperation can also be accomplished by computers, which can handle shared resources simultaneously, while sharing processor time.

Cooperative systems

Cooperation, more formally speak is how the components of a system work together to achieve the global properties. In other words, individual components that appear to be “selfish” and independent work together to create a highly complex, greater-than-the-sum-of-its-parts system. Examples can be found all around us. The components in a cell work together to keep it living. Cells work together and communicate to produce multicellular organisms. Organisms form food chains and ecosystems. People form families, gangs, cities and nations. Neurons create thought and consciousness. Atoms cooperate in a simple way, by combining to make up molecules. Understanding the mechanisms that create cooperating agents in a system is one of the most important and least well understood phenomena in nature, though there has not been a lack of effort.

However, cooperation may be coerced (forced), voluntary (freely chosen), or even unintentional, and consequently individuals and groups might cooperate even though they have almost nothing in common qua interests or goals. Examples of that can be found in market trade, military wars, families, workplaces, schools and prisons, and more generally any institution or organisation of which individuals are part (out of own choice, by law, or forced).

Cooperation vs. competition

Cooperation in many areas, such as farming and housing, may be in the form of a cooperative or, alternately, in the form of a conventional business.

Many people resort to this because, they may cooperate by trading with each other or by altruistic sharing.

Certain forms of cooperation are illegal in some jurisdictions because they alter the nature of access by others to economic or other resources. Thus, cooperation in the form of cartels or price-fixing may be illegal.

A few mechanisms have been suggested for the appearance of cooperation between humans or in natural system

The Prisoner's Dilemma

Even if all members of a group would benefit if all cooperate, individual self-interest may not favor cooperation. The prisoner's dilemma codifies this problem and has been the subject of much research, both theoretical and experimental. Results from experimental economics show that humans often act more cooperatively than strict self-interest would seem to dictate.
