Neoclassical Economics is an economic theory that emerged in the late 19th and early 20th centuries, emphasizing the role of supply and demand in regulating markets, with individual rationality and market efficiency as foundational principles. Neoclassical economics is based on three core assumptions: rational choice, marginal analysis, and equilibrium.Key characteristics include:Rational Choice: Assumes individuals are rational and make decisions to maximize their self-interest.Marginal Analysis: Focuses on marginal costs and marginal benefits, asserting that economic decisions should be based on marginal changes.Equilibrium: Markets achieve equilibrium through price mechanisms, ensuring optimal resource allocation.Microeconomic Foundations: Based on microeconomics, it studies the economic behavior and interactions of individuals, households, and firms.Example of Neoclassical Economics application:Consider a product market where the price of a good is determined by supply and demand. If the price is too high, suppliers will increase supply while consumers will reduce demand, leading to a price decrease. Conversely, if the price is too low, supply will decrease and demand will increase, causing the price to rise. Eventually, the market reaches an equilibrium where supply equals demand, and resources are optimally allocated. This illustrates the neoclassical principle of price mechanism regulating the market.

Definition

Neoclassical Economics is a school of economic thought that developed from the late 19th to early 20th century. It emphasizes the automatic regulation of markets through supply and demand, considering individual rationality and market efficiency as the foundation of economic behavior. Neoclassical economics is primarily based on three core assumptions: rational choice, marginal analysis, and equilibrium state.

Origin

Neoclassical economics originated in the late 19th century as a continuation and development of classical economics. Its development was influenced by the Marginal Revolution, which refers to the marginal utility theory proposed by economists like William Stanley Jevons, Carl Menger, and Léon Walras in the 1870s. This theory emphasized the importance of marginal analysis, forming the basis of neoclassical economics.

Categories and Features

The main features of neoclassical economics include:
1. Rational Choice: Assumes individuals are rational in economic decision-making, aiming to maximize their self-interest.
2. Marginal Analysis: Focuses on the analysis of marginal costs and benefits, suggesting economic decisions should be based on marginal changes.
3. Equilibrium State: Markets achieve supply-demand equilibrium through price mechanisms, optimally allocating resources.
4. Microeconomic Foundation: Based on microeconomics, studying the economic behavior and interactions of individuals, households, and firms.

Case Studies

A typical case is the price adjustment mechanism in a commodity market. Assume that in a commodity market, prices are determined by supply and demand. When the price of a commodity is too high, suppliers increase supply while consumer demand decreases, leading to a price drop. Conversely, when the price is too low, supply decreases, demand increases, and prices rise. Eventually, the market reaches a supply-demand balance, optimally allocating resources. This illustrates the basic principle of price mechanism regulation in neoclassical economics.

Common Issues

Investors may encounter issues when applying neoclassical economics, such as:
1. Limitations of Rational Assumption: In reality, individuals do not always make rational decisions.
2. Market Failures: Markets do not always automatically reach equilibrium and may require government intervention.

Technical Indicator

Technical indicators are heuristic or pattern-based signals produced by the price, volume, and/or open interest of a security or contract used by traders who follow technical analysis.By analyzing historical data, technical analysts use indicators to predict future price movements. Examples of common technical indicators include the Relative Strength Index (RSI), Money Flow Index (MFI), stochastics, moving average convergence divergence (MACD), and Bollinger Bands.

Technical Analysis

Technical analysis is a trading discipline employed to evaluate investments and identify trading opportunities by analyzing statistical trends gathered from trading activity, such as price movement and volume. Unlike fundamental analysis, which attempts to evaluate a security's value based on business results such as sales and earnings, technical analysis focuses on the study of price and volume.

Basis Risk

Basis Risk refers to the risk that arises when there is a difference between the spot price of an asset and the futures price of that asset (known as the basis) during hedging with financial derivatives. Specifically, when investors or businesses use futures contracts to hedge against price fluctuations in the spot market, if the changes in the spot price and the futures price do not move in perfect correlation, the hedging may be less effective, leading to potential losses. For instance, a farmer uses wheat futures to hedge against the risk of a decline in crop prices, but if the difference between the spot price and the futures price of wheat at the time of contract expiration is greater than expected, this change in basis represents the basis risk. Basis risk is common in commodity markets, foreign exchange markets, and interest rate markets.

Opportunity Cost

Opportunity costs represent the potential benefits that an individual, investor, or business misses out on when choosing one alternative over another. Because opportunity costs are unseen by definition, they can be easily overlooked. Understanding the potential missed opportunities when a business or individual chooses one investment over another allows for better decision making.

Hurdle Rate

The Hurdle Rate, also known as the Minimum Acceptable Rate of Return (MARR) or Required Rate of Return (RRR), is the minimum rate of return on an investment project that a company or investor is willing to accept before proceeding with the investment. This rate is set by the company's management or investors and serves as a benchmark for evaluating the feasibility of investment projects. The hurdle rate takes into account the cost of capital, risk premium, and other factors to ensure that the investment yields sufficient returns to compensate for the risks involved. If the expected return on a project is below the hurdle rate, the project is typically rejected. The hurdle rate is crucial in capital budgeting and project evaluation, aiding companies in effective resource allocation and risk management.

Horizontal Spread

A Horizontal Spread, also known as a Time Spread or Calendar Spread, is an options trading strategy. This strategy involves simultaneously buying and selling options contracts with the same strike price but different expiration dates. Typically, a trader will buy a long-term option and sell a short-term option. The goal of a horizontal spread is to profit from the difference in time value, especially when the underlying asset's price is not expected to move significantly. By employing this strategy, traders can benefit from the different rates of time decay (the reduction in the value of an option as it approaches its expiration date). Horizontal spreads are suitable for investors who have an expectation of market volatility but are uncertain about the specific direction of the price movement.
