The economic definition of elasticity was first given by a marshall in 1885 a well- known english scientist did not invent this concept, but using the achievements of english classics (a smith and d ricardo) and the mathematical school in economic theory, gave a definition of the coefficient of price elasticity of demand. Introduction to price elasticity of demand price elasticity of demand is a concept which doesn't seem to be worth too much, because it tells you things like: 'cigarette sales aren't very affected by price changes because they're however, ped (price elasticity of demand) has value because it is a number, not an idea.
