The classical tradition of partial equilibrium theory had been to split the economy into separate markets, each of whose equilibrium conditions could be stated as a single equation determining a single variable. The theoretical apparatus of supply and demand curves developed by Fleeming Jenkin and Alfred Marshall provided a unified mathematical basis for this approach, which the Lausanne School generalized to general equilibrium theory. For macroeconomics the relevant partial theories were:

Many such beliefs form the difference between the two major schools of thought in economics: Classical and Keynesian economics. WealthHow Staff Last Updated: Mar 26, Macroeconomics considers the performance of the economy as a whole, which involves two major approaches to study the pattern and influence on the economy.
Economists who believe in either of the types of thoughts are at loggerheads about various aspects about the way the economy influences people and vice-versa.
The strong form of the Say's law stated that the "costs of output are always covered in the aggregate by the sale-proceeds resulting from demand". Keynes argues that this can only hold true if the individual savings exactly equal the aggregate investment. Keynesian economics does not believe that price adjustments are possible easily and so the self-correcting market mechanism based on flexible prices also obviously doesn't.
The Keynesian economists actually explain the determinants of saving, consumption, investment, and production differently than the Classical. The Keynesian theorists on the other hand, believe that Government intervention in the form of monetary and fiscal policies is an absolute must to keep the economy running smoothly.
Keynes was completely opposed to this, and believed that it is the short run that should be targeted first. Keynes argued that interest rates do not usually fall or rise perfectly in proportion to the demand and supply of loanable funds.
They are known to overshoot or undershoot at times as well. But while Keynes argued for corrective Government intervention, Classical theorists relied on people's selfish motives to sort the system out. For a much better understanding of the difference it is essential that we delve a little deeper and try to understand the basics of these two approaches.
Let us start with a general overview of what this school of thought propagates. By the way, I am an out-and-out Classical economist, so forgive any biases that might creep in. Also understand, that even if it may seem so in this particular article at times, one cannot conclude that Keynesian economics is flawed or classical economics is flawed there's no absolute right and wrong in economics, different theories are applicable under different economic assumptions.
Definition and Groundwork for the Classical Economics Model "By pursuing his own interest, he man frequently promotes that good of the society more effectually than when he really intends to promote it.
I Adam Smith have never known much good done by those who affected to trade for the public good. Adam Smith is a great economist, who is known as the founder of the classical economics school of thought. The Classical economics theory is based on the premise that free markets can regulate themselves if left alone, free of any human intervention.
Adam Smith's book, 'The Wealth of Nations', that started a worldwide Classical wave, stresses on there being an automatic mechanism that moves markets towards a natural equilibrium, without the requirement of any intervention at all.
Classical Economics Assumptions Before working our way towards the working of this model, let us first know and understand the assumptions. The idea, is that like any theory, if the founding assumptions do not hold, the theory based on them is bound to fail.
There are three basic assumptions. The prices of everything, the commodities, labor wagesland rentetc. Unfortunately, in reality, it has been observed that these prices are not as readily flexible downwards as they are upwards, due a variety of market imperfections, like laws, unions, etc.
The Say's law suggests that the aggregate production in an economy must generate an income enough to purchase all the economy's output. In other words, if a good is produced, it has to be bought.
Unfortunately, this assumption also does not hold good today, as most economies today are demand driven production is based on demand. Demand is not based on production or supply. This assumption requires the household savings to equal the capital investment expenditures.Classical economics or classical political economy is a school of thought in economics that flourished, primarily in Britain, in the late 18th and early-to-mid 19th century.
Its main thinkers are held to be Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Robert Malthus, and John Stuart Mill. - John Keynes's famous quote to stop the Classical economists from rapping about the 'long run'. Keynesian economics is completely based on a simple logic - there is no divine entity, nor some invisible hand, that can tide us over economic difficulties, and we must all do so ourselves.

In the s, however, new classical economists such as Robert Lucas, Thomas J. Sargent, and Robert . Keynes's formulation. Keynes coined the phrase thusly (emphasis added): From the time of Say and Ricardo the classical economists have taught that supply creates its own demand; —meaning by this in some significant, but not clearly defined, sense that the whole of the costs of production must necessarily be spent in the aggregate, directly or .
The new classical economists of the mids attributed economic downturns to people’s misperceptions about what was happening to relative prices (such as real wages). Misperceptions would arise, they argued, if people did not know the current price level or inflation rate.
