Classical economics, also known as the classical school of economics, [1] or classical political economy, is a school of thought in political economy that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century. It includes both the Smithian and Ricardian schools. [2]
The tableau économique is credited as the "first precise formulation" of interdependent systems in economics and the origin of the theory of the multiplier in economics. [5] An analogous table is used in the theory of money creation under fractional-reserve banking by relending of deposits, leading to the money multiplier .
Chapter 20 covers mathematical groundwork for Chapter 21, which examines how changes in income from increased money supply affect wages, prices, employment, and profits. Keynes disagrees with the classical view that flexible wages can cure unemployment, arguing that interest rates have a more significant impact on employment.
Input–output economics has been used to study regional economies within a nation, and as a tool for national and regional economic planning. A main use of input–output analysis is to measure the economic impacts of events as well as public investments or programs as shown by IMPLAN and Regional Input–Output Modeling System. It is also ...
The Keynesian cross diagram is a formulation of the central ideas in Keynes' General Theory of Employment, Interest and Money.It first appeared as a central component of macroeconomic theory as it was taught by Paul Samuelson in his textbook, Economics: An Introductory Analysis.
The 'first postulate' of classical economics was also accepted as valid by Keynes, though not used in the first four books of the General Theory. The Keynesian system can thus be represented by three equations in three variables as shown below, roughly following Hicks. Three analogous equations can be given for classical economics.
Economic graphs are presented only in the first quadrant of the Cartesian plane when the variables conceptually can only take on non-negative values (such as the quantity of a product that is produced). Even though the axes refer to numerical variables, specific values are often not introduced if a conceptual point is being made that would ...
New classical economics made its first attempt to model aggregate supply in Lucas and Leonard Rapping (1969). [2] In this earlier model, supply (specifically labor supply) is a direct function of real wages: more work will be done when real wages are high and less when they are low. Under this model, unemployment is "voluntary". [3]
