In economics, what is meant by "optimal decisions are made at the margin?" The concept of the margin was initially developed in 2012 by Professor Marginus; research is still being done on how it can be used for decision-making. The idea of the margin does not help compare trade-offs and is not relevant to decision-making. The idea of the margin is related to making decisions while thinking about the benefits and costs of small changes in behavior. The idea of the margin is that all economic decisions are made at the very fringes of society.

Answer:

The idea of the margin is related to making decisions while thinking about the benefits and costs of small changes in behavior.

Explanation:

Economic theory suggests that economic agents (firms, consumers and government) think on the sidelines. This means that decisions are made taking into consideration the benefits and costs of each choice. For example, for a firm to increase a unit of production (marginal unit) it will calculate the cost of production of that unit (marginal cost) and the profit that additional unit will generate (marginal benefit).
