[Презентация] Neoclassical economic theory

Neoclassical economic theory is one of the major schools of economic thought that emerged in the late 19th century and has had a significant impact on economic science. It developed as a reaction to classical economic theory and focused on the study of market mechanisms, consumer and producer behavior. This theory is widely used in modern economic analysis and plays an important role in the formation of economic policy in many countries.

Neoclassical economists believe that individuals act rationally to maximize their utility (consumers) or profit (producers). 1. Assumption of rationality 2. Marginal utility An important concept is marginal utility, which describes how consumers make decisions to consume goods and services. Each successive single good yields an increasingly smaller utility. 3. Competition Neoclassical theory emphasizes the role of perfect competition in ensuring efficient allocation of resources. The market, where there are many sellers and buyers, contributes to the optimization of prices and output. 4. Market as a mechanism Neoclassicists view the market as a self-regulating mechanism that reaches equilibrium through the interaction of supply and demand. 5. Capital and labor Neoclassical theory also considers factors of production, such as labor and capital, and their impact on economic growth and income distribution.

- William Stanley Jevons: One of the first economists to propose the concept of marginal utility. - Leon Walras: Developed a mathematical model of general equilibrium in which he described how all markets in an economy are interrelated. - Carl Menger: Founder of the Austrian school of economics who emphasized the subjective nature of value and utility. - Alfred Marshall: Introduced the concepts of elasticity of supply and demand and developed graphical methods for analyzing market equilibrium.

Neoclassical economic theory began to take shape in the 1870s and continued to develop until the early 20th century. It became the dominant paradigm in economic science until the 1930s, when criticism of neoclassical approaches began in connection with the Great Depression. Nevertheless, many ideas of neoclassical theory continue to be used in modern economic models.
