  • What is the law of diminishing marginal utility?

    The law of diminishing marginal utility is a law of economics stating that as a person increases consumption of a product while keeping consumption of other products constant, there is a decline in the marginal utility that person derives from consuming each additional unit of that product.
  • What is an example of a marginal benefit?

    Marginal benefit is the incremental increase in the benefit to a consumer caused by the consumption of one additional unit of a good or service. As a consumer's consumption level increases, the marginal benefit tends to decrease (which is called diminishing marginal utility).
  • Is pollution an external cost?

  • What can cause a production possibility curve to move to the right?

    This causes output to increase, so the production possibilities curve shifts outward, or to the right. On the other hand, let's say a major war causes destruction of capital equipment in the country. This would cause output to decrease, so in this case, the production possibilities curve shifts inward, or to the left.
