Document Summary
Econ101 004 lecture 3 - using resources efficiently. The ppf determines marginal cost (slope of ppf) Marginal cost: the additional opportunity cost of producing one more unit of it. Marginal benefit curve: shows the relationship between the good and the quantity of the good. Note: marginal benefit curve is unrelated to ppf; you can only derive marginal cost from ppf. The principle of decreasing marginal benefit: the falling satisfaction we derive from consuming an additional g/s. Since each additional g/s is worth less and less to us with a smaller marginal benefit, we are willing to pay less for an additional unit of it marginal benefit from a. Allocative efficiency: any points on the ppf are efficient. To use resources in research and development and to produce new capital, we must decrease our production of consumption g/s. Therefore, economic growth it not free, and does not abolish scarcity.
