The Prisoner's Dilemma

The Prisoner's Dilemma is a fundamental concept in economics and game theory. At its simplest, it illustrates why cooperation can be challenging, even when mutually beneficial. This difficulty arises because one party cannot reliably predict the other's actions. For example, consider two farms alongside a river. The river will flood unless $1,000 is spent on flood control. Both farmers will suffer significant losses if it floods. The optimal solution is for both farmers to pay $500 each. However, each farmer knows that if the other farmer paid the full $1,000, they would receive the benefit of flood control for free. Consequently, each waits for the other to pay the entire $1,000. In the meantime, the river floods. This... Continue reading "Essential Economic Concepts: Dilemmas, Trade, and Market Dynamics" »
