Principles of Economics, Vol. 2, 8th Ed.

Alfred Marshall dominated the world of Economics from about 1890 until his death in 1924. In his most important book, Principles of Economics, he emphasized that the price and output of a good are determined by both supply and demand: the two curves are like scissor blades that intersect at equilibrium. His primary concern in Principles was Microeconomics, the study of Individual markets and industries, and not the whole economy. Modern economists, trying to understand why the price of a good changes, still start by looking for factors that may have shifted demand or supplyan approach they owe to Marshall.

Marshall used the tools of classical mechanics, including the concept of optimization, to make Economics dynamic rather than static. Like neo-classical economists who have followed in his footsteps, Marshall took technology, market institutions, and peoples preferences as given. However he believed that the Mecca of the economist lies in economic biology rather than in economic dynamics. The economy, according to him, is an evolutionary process in which technology, market institutions, and peoples preferences evolve along with peoples behaviour.

Principles of Economics, first published in 1890, went through eight editions and is considered the most important treatise of 19th century and beyond. It gave some landmark concepts like consumer surplus, producer surplus, price elasticity of demand, and the idea of three periods, viz. market period, short period and long period. The concept of National Dividend given in the Principles is not a mere academic toy, but a practical instrument of great power designed for service in the concrete solution of social problems. Marshalls theoretic discussion follows the lines of the mathematical treatment of Cournot and others, more particularly in his discussion of the doctrines of value, cost, exchange, and distribution. He has used diagrams and formulae for purposes of illustration and for greater precision of statement.

This reprint of the book with a comprehensive Introduction has been brought to help the students, teachers and researchers of Economics in their academic pursuits, and for the economists to delve deeply into the subject and draw valuable conclusions for future progress of society.
