Classical Economists: Adam Smith

Adam Smith, a prominent figure among the classical economists, is best known for his seminal work ‘The Wealth of Nations,’ where he presents the concept of the ‘invisible hand.’ This metaphor describes how individuals pursuing their self-interest unintentionally contribute to the economic well-being of society. Smith posited that as individuals strive to maximize their own gain, they are led by an invisible hand to promote an end which was no part of their intention, namely the public interest. Through this process, free markets are able to self-regulate and allocate resources efficiently without the need for direct intervention…Read&Listen More

Marxist Economics

Marxist Economics is rooted in the work of Karl Marx, a 19th-century philosopher, economist, and revolutionary. It encompasses a critical analysis of capitalism, a theory of social change, and a vision for a post-capitalist society. The perspective is based on the concept of historical materialism, which posits that material conditions and economic activities shape social structures and human history. Marx believed that capitalism, characterized by private ownership of the means of production and the creation of goods or services for profit, leads to class struggles between the bourgeoisie (capitalists who own the means of production) and the proletariat (workers who sell their labor)…Read&Listen More

Marginalist Revolution

The Marginalist Revolution, a pivotal shift in economic theory during the late 19th century, introduced a new way of analyzing prices and the allocation of resources. This period marked a transition from classical to neoclassical economics, with the introduction of the concept of marginal utility. Economists began to understand that the value of a good is not derived from its production costs or labor inputs, as previously thought, but rather from the utility that an additional unit of the good provides to consumers. This was a radical departure from classical theories that primarily focused on the cost of production as the determinant of value…Read&Listen More

Keynesian Economics

Keynesian Economics, as originally formulated by John Maynard Keynes, conveys the idea that aggregate demand is often influenced by a host of economic decisions—both public and private—and sometimes behaves erratically. The public or government can therefore play a role in stabilizing the economy over the course of the business cycle. Keynes suggested that during times of low economic activity and high unemployment, the government should increase spending and/or cut taxes to stimulate demand and pull the economy out of recession…Read&Listen More
