Supply

Supply may refer to:

Supply (economics)

In economics, supply is the amount of something that firms, consumers, laborers, providers of financial assets, or other economic agents are willing to provide to the marketplace. Supply is often plotted graphically with the quantity provided (the dependent variable) plotted horizontally and the price (the independent variable) plotted vertically.

In the goods market, supply is the amount of a product per unit of time that producers are willing to sell at various given prices when all other factors are held constant. In the labor market, the supply of labor is the amount of time per week, month, or year that individuals are willing to spend working, as a function of the wage rate. In the financial markets, the money supply is the amount of highly liquid assets available in the money market, which is either determined or influenced by a country's monetary authority.

The remainder of this article focuses on the supply of goods.

Supply schedule

A supply schedule is a table which shows how much one or more firms will be willing to supply at particular prices under the existing circumstances. Some of the more important factors affecting supply are the good's own price, the prices of related goods, production costs, technology and expectations of sellers.

Money bill

In the Westminster system (and, colloquially, in the United States), a money bill or supply bill is a bill that solely concerns taxation or government spending (also known as appropriation of money), as opposed to changes in public law.

Conventions

It is often a constitutional convention that the upper house may not block supply. There is often another requirement that non-money bill type clauses may not be attached to a money bill.

Loss of supply in the lower house is conventionally considered to be an expression of the house's loss of confidence in the government resulting in the government's fall.

Requirements in Westminster Systems

Australia

A supply bill in the Australian System is required to pass the House of Representatives, the Senate and be signed by the Governor-General. The Senate has no power or ability to introduce or modify a supply bill, but has the ability to block or defer the passing of a supply bill. The most famous instance where supply was blocked was during the 1975 constitutional crisis. This has resulted in agreements between political parties to prevent the blockage of supply bills through the Senate.
