Classical And Keynesian Economics: The Concepts Of Classical Economics

Classical economics as postulated by the 19th century British economist David Ricardo states – in modern economic terms – that an economy will achieve its natural levels of employment (full employment) and reach its potential output on its own without any government intervention. While the economy may undergo periods of less than natural levels of employment or not yet reach its potential output, it will, in the long run do so. If Mr. Ricardo was still alive, his favorite album would be The Long Run by The Eagles (1979). Using modern economic terms to further describe classical economics, an economy will tend to operate at a level given by the long run aggregate supply curve. While many believe that the concepts of classical economics are for

The Classical economists believe that these are “temporary” changes that will correct themselves in the long run. They feel that an economy will always tend towards operating at its potential output (as given by the long-run aggregate supply curve. Nothing needs to be done by the government because normal market forces will serve to self-correct these issues. On the other hand, Keynesian economics argue that the gap between the lower and the potential levels of output is due to a change in aggregate demand. They argue that this gap can exist for a long time and that the gap can be pushed to close faster if the government enacts fiscal and monetary policies. There are differences in how each policy works to close the recessionary gap caused by a drop in aggregate

Regardless, in regards to applying Keynesian economic policies toward the Great Depression, Former Federal Reserve Governor Ben S. Bernanke said “You 're right, we did it. We 're very sorry. … we won 't do it again” (Federal Reserve Board, 2002). Other economic theory must be developed to address some of the shortcomings of the Keynesian economic
