Difference Between Classical Economics and Neoclassical Economics

Classical economics and neoclassical economics are two ways of looking at how economies work. While both share some fundamental principles, they also diverge in their approaches and emphases.

Difference Between Classical Economics and Neoclassical Economics Classical economics is like the older version, focusing on things like supply and demand to explain how prices and production are decided.

Neoclassical economics is a newer approach that builds on classical ideas but also includes more about how people make choices and how businesses and markets interact.

Understanding Classical Economics

Classical economics holds that an economy can work best on its own without the government getting involved. According to this theory, people will sort out what they need and how to share resources without help.

Difference Between Classical Economics and Neoclassical Economics

In a classical economy, prices are decided based on how much it costs to make something, such as materials, labor, electricity, and other costs. The government doesn't spend a lot on classical economics. Instead, what's really important is how much consumers spend on things they buy and how much companies invest because that's what keeps the economy moving.

Assumptions to Classical Economics

  1. A free-market capitalist system runs itself using natural rules for making and trading things.
  2. The rule of supply and demand helps the business cycle manage itself. This leads to a hands-off system where the government has a small role in steering the economy.
  3. Unrestricted competition and free trade, without government intervention or control, would help boost economic progress.
  4. If society allows individuals to follow their interests freely, especially by moving away from class-based social structures and supporting merit-based systems, the country's economy can flourish.
  5. The initial chaos caused by competitive buying and selling would eventually transition into a structured system of economic cooperation, where economic players work together to fulfill each other's needs.
  6. A comparative advantage allows a country to be a more effective producer by focusing on what it's best at. Moreover, countries gain by importing from others that can produce things more cheaply than they could at home.

Criticisms of Classical Economics

  • Classical economists had conflicting ideas and views about markets, which made their theories and concepts inconsistent.
  • Marxian economics, along with its ideas of socialism and communism, goes against traditional economic principles that support free competition and capitalism.
  • Keynes highlighted that capitalist and free-market economic systems can still face issues of underconsumption and insufficient spending.
  • Keynesians advocated for economic policies that involve government intervention to promote and implement them in the economy.

Understanding Neoclassical Economics

Neoclassical economics is a detailed method that employs supply and demand to explain how products and services are produced, priced, consumed, and distributed. It merges classical economics' cost-of-production theory with the idea of utility maximization. Stanley Jevons, Maria Edgeworth, Leon Walras, Vilfredo Pareto, and other economists made significant contributions to neoclassical economics.

Difference Between Classical Economics and Neoclassical Economics

Neoclassical economics emerged in the early 20th century, and in 1933, it integrated imperfect competition models. This period saw the introduction of innovative techniques like indifference curves and marginal revenue curves, enhancing its mathematical sophistication and promoting the advancement of neoclassical economics.

In the 1950s, economists combined Keynesian macroeconomic concepts with neoclassical microeconomic ideas, leading to the development of the neoclassical synthesis. This synthesis has been the dominant framework in economic reasoning ever since. Assumptions of Neoclassical Economics

1) Free Markets

Neoclassical economics asserts that markets should operate without significant government interference; when left to themselves, markets will naturally balance based on supply and demand dynamics. Moreover, free markets offer consumers a wider range of choices.

2) Savings Generate Investment Opportunities

Neoclassical economists believe that a higher interest rate motivates people to save more, leading to increased investment. When consumers are given a higher return on their savings, they are more likely to invest those savings.

3) Consumers are Rational Agents

Neoclassical economics views consumers as rational actors who buy goods based on their utility. They consider factors like price, utility, and satisfaction before deciding to make a purchase.

4) The Perceived Value of Goods and Services

The neoclassical school of thought suggests that consumers assign a perceived value to a product or service, which is often higher than its actual value. They argue that consumers form their perceptions about a product. In this view, a product's price is based on its "perceived value" rather than its "cost of production."

5) Law of Diminishing Marginal Utility

The Law of Diminishing Marginal Utility states that as a consumer consumes more units of a good or service, the satisfaction or utility derived from each additional unit decreases.

6) Market Stability

According to neoclassical economists, market equilibrium is reached when both consumers and producers achieve their goals. This occurs when sellers sell their goods at acceptable prices, and consumers buy items at prices they are willing to pay, leading to a balanced market.

7) Access to Relevant Information

Neoclassical economists believe that consumers have access to all relevant information about a product. They also suggest that consumers may make decisions based on the data that is available to them.

Criticisms of Neoclassical Economics

1) Irrational Assumptions

One common criticism of neoclassical economics is that it relies on unrealistic assumptions. It assumes people always make rational choices, ignoring how we can act irrationally or be influenced by emotions. Behavioral economics looks into these irrational decisions, using real evidence to understand how people behave in the economy. There's also a debate about whether individuals or businesses should only focus on maximizing utility or profits.

2) Excessive Dependency on Mathematical Approaches

Critics argue that neoclassical economics relies too much on math and lacks real-world evidence. The heavy use of theoretical models falls short of explaining how people actually interact in the economy. This approach can also lead to biased conclusions about what should be considered normal or acceptable.

3) Excessive Emphasis on Complicated,Unreasonable Mathematical Models

Critics also point out that neoclassical economics depends too heavily on complex and unrealistic mathematical models, which don't accurately represent the real economy. Milton Friedman, an American economist, argued that a theory should be judged based on how well it predicts real-world outcomes, not just on the complexity of its models or the realism of its assumptions.

Difference Between Classical Economics and Neoclassical Economics

Classical EconomicsNeoclassical Economics
It refers to the price of something is decided by how much it costs to make. This includes everything needed to produce it, like labor, equipment, land, and the effort of the people involved."Neoclassical economics" as a comprehensive theory that underscores the importance of supply and demand in influencing the production, pricing, and consumption of goods and services.
Classical economics became popular in the late 1700s and throughout the 1800s, particularly in Britain.Neoclassical economics was the dominant framework in microeconomics from the 1950s to the 1970s. It later evolved into Neo-Keynesian economics, further solidifying its position in mainstream economics.
The main thinkers in classical economics were Adam Smith, Jean-Baptiste Say, David Ricardo, Thomas Malthus, and John Stuart Mill.Neoclassical economics drew influence from economists like Stanley Jevons, Maria Edgeworth, Leon Walras, Vilfredo Pareto, and several others.
The classical school of economics focuses on explaining how economic systems grow and shrink, considering the overall economy in its assessments and forecasts.The neoclassical school of thought, interprets individual or company behaviors within a larger system. In contrast, the neoclassical technique often adopts a segmented approach, focusing on specific components.
Classical economics is an empirical field that seeks to understand capitalism's production system by analyzing social and historical factors.Neoclassical economics relies heavily on mathematical models for its analysis, preferring a mathematical approach over a historical one.
In classical economics, equilibrium happens when the amount of money people save is the same as the amount of money being invested.In neoclassical economics, equilibrium is determined by the interaction of supply and demand across all markets. This balance occurs where the supply and demand curves intersect.
In classical economics, profit is a reward given to a capitalist for performing a socially beneficial role.In neoclassical economics, profit is commonly defined as the gap between revenues and costs.

Conclusion

Classical economics focuses on the overall economy and how it works, while neoclassical economics zooms in on individuals and companies to understand their behavior within the economy. Classical economics, rooted in the works of Adam Smith and David Ricardo, emphasizes the functioning of the economy as a whole, with a focus on factors such as production, consumption, and distribution of goods and services. It analyzes aggregate phenomena like inflation, unemployment, and economic growth.

In contrast, neoclassical economics, which emerged in the late 19th century, delves into the micro-level behavior of individual agents, including consumers, firms, and workers. It employs concepts like utility maximization, cost-benefit analysis, and rational choice theory to explain decision-making within markets and industries. Neoclassical economists often use mathematical models to study these interactions and derive insights into market equilibrium, resource allocation, and welfare economics.
