Marginalist Economists

Marginalist School

Classical economists theorized that prices are determined by the costs of production. Marginalist economists emphasized that prices also depend upon the level of demand, which in turn depends upon the amount of consumer satisfaction provided by individual goods and services.

Marginalists provided modern macroeconomics with the basic analytic tools of demand and supply, consumer utility, and a mathematical framework for using those tools. Marginalists also showed that in a free market economy, the factors of production -- land, labor, and capital -- receive returns equal to their contributions to production. This principle was sometimes used to justify the existing distribution of income: that people earned exactly what they or their property contributed to production.

Marxist School

The Marxist School challenged the foundations of Classical theory. Writing during the mid-19th century, Karl Marx saw capitalism as an evolutionary phase in economic development. He believed that capitalism would ultimately destroy itself and be succeeded by a world without private property.

An advocate of a labor theory of value, Marx believed that all production belongs to labor because workers produce all value within society. He believed that the market system allows capitalists, the owners of machinery and factories, to exploit workers by denying them a fair share of what they produce. Marx predicted that capitalism would produce growing misery for workers as competition for profit led capitalists to adopt labor-saving machinery, creating a "reserve army of the unemployed" who would eventually rise up and seize the means of production.
