Question

1. economics believe that the best decisions are made at the________. margin tradeoff alternative opportunity

Explanation:

In economics, the concept of making decisions at the margin is fundamental. Marginal analysis involves comparing the marginal (additional) benefits and marginal (additional) costs of a decision. For example, a firm decides whether to produce one more unit by looking at the extra revenue (marginal benefit) and extra cost (marginal cost) of that unit. Trade - off refers to giving up one thing for another (e.g., time for money). An alternative is just another option. Opportunity is related to the cost of the next - best alternative forgone (opportunity cost). But the key term for where the best decisions are made in the economic sense (through comparing incremental changes) is at the margin.

Answer:

margin
