RESERVE RATIO: The amount of reserves required by the Federal Reserve System as a ratio of the amount deposits backed by the reserves. Modern reserve ratios are in the range of 1-3% for checkable deposits. The reserve ratio plays a key role in the deposit multiplier. The simple deposit multiplier is simply the inverse of the reserve ratio. If the reserve ratio is 5%, then the deposit multiplier is 20. It's just that simple.

LAW OF COMPARATIVE ADVANTAGE

A principle that states that every nation, worker, or production entity has a production activity that incurs a lower opportunity cost than that of another nation, worker, or production entity, which means that trade between the two can be beneficial to both if each specializes in the production of a good with lower relative opportunity cost. This law is most often studied in the confines of international trade, but it also applies to labor and other types of production.
