POINT ELASTICITY: The relatively 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.< P>Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) can calculate point elasticity by taking derivatives of equations. Derivatives is fancy calculus talk for infinitesimally small changes.

FIXED EXCHANGE RATE An exchange rate that is established at a specific level and maintained through government actions (usually through monetary policy actions of a central bank). To fix an exchange rate, a government must be willing to buy and sell currency in the foreign exchange market in whatever amounts are necessary to keep the exchange rate fixed. A fixed exchange rate typically disrupts the balance of trade and balance of payments for a country. But in many cases, this is exactly what a country is seeking to do. This is one of three basic exchange rate policies used by domestic governments. The other two policies are flexible exchange rate and managed flexible exchange rate.
