ECLA: The Economic Commission for Latin America (ECLA) -the Spanish acronym is CEPAL- was established in 1948. ECLAC, which is headquartered in Santiago, Chile, is one of the five regional commissions of the United Nations. It was founded for the purposes of contributing to the economic development of Latin America, coordinating actions directed towards this end, and reinforcing economic relationships among the countries and with the other nations of the world. The promotion of the region's social development was later included among its primary objectives. The 33 countries of Latin America and the Caribbean are member States of ECLAC, together with several North American and European nations that have historical, economic and cultural ties with the region.

                           POINT ELASTICITY: The relative responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve. Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) calculate point elasticity by using derivatives. Derivatives are calculus talk for infinitesimally small changes. The formula for calculating point elasticity using calculus is given as:The symbol that looks like a backward six (∂) is the mathematical notation for a derivative, or infinitesimally small change. The first term on the right-hand side of this formula is the percentage change in variable B and the second term is the percentage change in variable A.Unsophisticated folks can also calculate point elasticity without the use of sophisticated calculus. This is done with the midpoint elasticity formula, presented here: midpoint
elasticity | = | (B2 - B1)
(B2 + B1)/2 | ÷ | (A2 - A1)
(A2 + A1)/2 |
The first term on the right-hand side of the equation is the percentage change in variable B. The second term is the percentage change in variable A. The individual items are interpreted as this: A1 is the initial value of A before any changes, A2 is the ending value after A changes, B1 is the initial value of B before any changes, and B2 is the ending value after B changes.This midpoint elasticity formula actually calculates the average or arc elasticity of the entire line segment. However, it also calculates the point elasticity for the midpoint of a line segment.
