B: The common notation for the "slope" term of an equation specified as Y = a + bX. Mathematically, the b-slope term indicates the change in the value of the Y variable resulting from a unit change in the value of the X variable. Theoretically, the b-slope is frequently used to indicate endogenous or dependent relation between the Y and X variables. For example, if Y represents consumption and X represents national income, b measures induced consumption expenditures.

Topic: Fiat Money <=PAGE BACK | PAGE NEXT=>

Fiat money has little or no value in use compared to value in exchange. The value in exchange of fiat money is under control of an authority, usually government.

The transition:

  • First: Paper currency was backed by metal stored in a secure location. The paper could be traded for equivalent amounts of silver or gold.
  • Second: Because no one traded paper currency for metal, metal wasn't needed to back the paper. They just need a paper currency-to-metal exchange rate.
  • Third: Authorities stopped fixing the currency-to-metal exchange price. Paper currency was valuable based on the ability to purchase goods.

A two-edged sword:

  • Authority acquires the ability to control money and also the responsibility.
