DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

BALANCE ON SERVICES

A subset of the balance of payments current account that records the difference between the payments received for exports of services to other nations and the payments made for the imports of services from other nations. The flow of payments is for intangible services, not for physical or tangible goods. The balance on services is thus appropriately divided into services exported and services imported. Two other subsets of the current account include the balance on merchandise trade and unilateral transfers. The commonly termed balance of trade is the sum of the balance on merchandise trade and the balance on services.

Your Complete Scope

This isn't me! What am I?

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.
