How does the concept of economic calculation differ from dealing with the agent-principal problem? Explain in detail why Peter Klein says that.

Klein's assertion that modern economics emphasizes incentive issues brings about a difference between economic calculation and the agent-principal problem. According to Klein, the incentive theory tends to inquire on how a principal can acquire an agent for duties' delegation purposes, which can be used to counter the principal-agent problem. This is achievable when the principal extends incentives to the agent to get him to do what he wants.

In contrast, Klein argues that an organization is faced with economic calculation problems and principal-agent problems when it has attained growth enough to manage operations internally.
