Refutation of Classical Economics
In his seminal work, John Maynard Keynes challenges the classical economics notion that the economy is self-regulating and that it is always at or near full employment. He criticizes classical economists for their belief that the market system will naturally correct itself and that supply creates its own demand (Say’s Law). Keynes argues that this assumption is flawed and that, in reality, insufficient demand can lead to prolonged periods of high unemployment. He posits that it is possible for the aggregate demand to be insufficient to employ all those who are willing to work, leading to involuntary unemployment…Read&Listen More

Introduction of Aggregate Demand
The General Theory introduces aggregate demand as the total amount of goods and services demanded in the economy at a particular time and at a prevailing price level. It’s a concept that Keynes developed to describe the overall demand for goods and services in relation to employment and output. Aggregate demand is central to Keynesian economics and is used to explain fluctuations in the economy and guide government policy to maintain high levels of employment…Read&Listen More

The Principle of Effective Demand
The principle of effective demand is central to John Maynard Keynes’ theory and revolves around the idea that the level of employment in an economy is determined by the amount of effective demand. Effective demand refers to the total spending on goods and services by consumers, businesses, and the government at various levels of employment. According to Keynes, it is not the aggregate supply of goods and services that determines employment, but rather the aggregate effective demand for those goods and services…Read&Listen More

Interest and Liquidity Preference Theory
In the theory of liquidity preference, Keynes posits that the demand for money is not only for transactions and precautionary purposes, but also as a store of wealth. He argues that people prefer to hold liquid assets as a way to preserve their wealth because these assets can be easily converted into other forms of spending power without loss. This preference for liquidity arises due to uncertainty about the future and the desire to hold assets that can quickly be transformed into money if needed for unforeseen expenses or opportunities…Read&Listen More

Keynesian Economic Policy Recommendations
John Maynard Keynes’s magnum opus, ‘The General Theory of Employment, Interest, and Money,’ revolutionized economics by challenging classical economic thought and promoting a series of policy recommendations that would come to define Keynesian economics. He argued that in times of economic downturn, private sector demand often falls short of what is needed to maintain full employment. According to Keynes, it is the government’s role to intervene and offset this deficiency through active fiscal policies…Read&Listen More

The Multiplier Effect
The multiplier effect, as described, is a mechanism which amplifies the initial change in spending to lead to a greater overall increase in national income. It is rooted in the observation that one person’s spending becomes another person’s income. When an initial amount of spending is injected into the economy, it sets off a chain reaction of increased consumption. As the recipients of the initial spending also spend their new income on goods and services, this increases the income of others, and so on. Thus, a series of increments to income results, each one smaller than the last, but collectively summing to a larger total effect than the initial injection…Read&Listen More
