Emergence of Macroeconomics

This section traces the origin of macroeconomics as a distinct branch of economics to the publication of John Maynard Keynes' seminal book, 'The General Theory of Employment, Interest and Money' in 1936. Prior to Keynes, the classical economic tradition held that all laborers willing to work would find employment and factories would operate at full capacity, assuming markets would clear automatically. However, the Great Depression of 1929 shattered this belief as output and employment plummeted drastically in Europe and North America, with unemployment in the USA rising from 3% to 25% between 1929 and 1933 and aggregate output falling by about 33%. These events forced economists to rethink economic functioning. Keynes examined the economy as a whole, emphasizing the interdependence of different sectors and the possibility of prolonged unemployment. His work laid the foundation for macroeconomics, focusing on aggregate demand, employment, interest, and money. The section also provides a brief biography of Keynes, highlighting his education, diplomatic involvement, and influence on twentieth-century economics.
