Collaboration runs smoothly when the the involved parties trust each other. As Harari discusses in Sapiens, humans have invented many systems of shared values to establish this trust between people who lack a direct relationship - religion, government, companies, etc.
Another issue with trust is the alignment of incentives. Taleb discusses this in Skin in the Game as risk asymmetry. The principal-agent problem is when the party that is making decisions (the agent) and the party of those decisions are made for (the principal) have asymmetric exposure to the risks and rewards of those decisions.
A simplistic view is that each party has 2 possible outcomes; they can win or lose. There are 4 possible outcomes:
When the agent isn’t exposed to the risks of their decisions, they may not have the best interests of the principal in mind. This asymmetry of risk can lead to undesirable outcomes. The agent could take advantage of the Principal and still gain a reward, producing a lose-win outcome. Some examples:
