What Are The Historical Development Of Modern Macro-economics?

          The sphere and scope of economics has a history linked probably with the very first activity for profit and survival taken on by man. The scope expanded with the inclusion of a whole society participating in defined activities that affected life styles and the status of the nation.

          The study involves calculations that include the net and gross incomes of every individual in the country, societies and finally the calculation leads to the national income. Macro-economics is a branch of economics that specifically deals with the performance structure and resultant change within an economy. The concept was introduced in 1930, owing to the desperate situation created worldwide on account of the 'Great Depression' that resulted because of the First World War.

          The situation in the world was so grave, that many economies collapsed and dedicated economists took up the challenge to try and interpret the situation. They worked at the various reasons for industrial collapse and the steep decline in the money market. The observations resulted in the creation of a branch of economics, Macro Economics. The concept of the connectivity between National Income and Product Status thus came about and was first studied by John Maynard Keynes. However, the term was first coined in 1933 by Ragnar Frisch, an economist from Norway.
