EC120 Lecture Notes - Lecture 3: Opportunity Cost, Demand Curve, Inferior Good

Document Summary

Economic growth: economic growth, which is the expansion of production possibilities, results from capital accumulation and technological change, the opportunity cost of economic growth is forgone current consumption, the benefit of economic growth is increased future consumption. Firms coordinate a large amount of economic activity, but there is a limit to the efficient size of a firm: markets coordinate the economic choices of people and firms, markets can work efficiently only when property rights exist. When they are enforced, people have the incentive to specialize and produce the goods in which they have the comparative advantage: money makes trading in markets more efficient. Absolute advantage a person/country is more productive at something, excels and outperforms others in a large number of activities. Allocative efficiency a situation in which goods and services are produced at the lowest possible cost and in the quantities that provide the greatest possible benefit.
