BARTER: A method of trading goods, commodities, or services, directly for one another without the use of money. In a barter exchange one good is traded directly for another. This sort of exchange ultimately requires a double coincidence of wants, meaning that each trader has what the other trader wants and wants what the other has. Without a double coincidence of wants the exchange process can become exceedingly complex, requiring a great deal of resources to complete transactions, resources that can not be used for production. In fact, inefficient barter trading was the primary reason that money was invented. With money, more resources can be used for production and fewer are needed for trading.

FOUR-SECTOR INJECTIONS-LEAKAGES MODEL

A variation of the Keynesian injections-leakages model that adds the foreign sector to the three domestic sectors--the household sector, the business sector, and the government sector. This variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model and provides an alternative to the four-sector aggregate expenditures (Keynesian cross). It provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the S + T + M line and the I + G + X line. Two related variations are the two-sector injections-leakages model and the three-sector injections-leakages model.

Potato chips were invented in 1853 by a irritated chef repeatedly seeking to appease the hard to please Cornelius Vanderbilt who demanded french fried potatoes that were thinner and crisper than normal.
