Insider Trading

Background

Insider trading refers to the practice of buying or selling a publicly-traded company’s stock by someone who has non-public, material information about that stock. Insider trading can be either legal or illegal depending on when the insider makes the trade — it is illegal when the material information is still non-public.

Historical Context

Insider trading has been part of stock markets since their inception, but it became significantly regulated and scrutinized in the 20th century. The Stock Exchange existed without stringent regulations until scandals and financial fraud led to major reforms like the Securities Act of 1933 and the Securities Exchange Act of 1934 in the United States, which were instituted to protect investors and maintain fair and efficient markets.

Definitions and Concepts

At its core, insider trading involves the exploitation of private material information for personal gain in the securities market. Legal insider trading involves insiders buying or selling stock of their own companies but abiding by rules and regulations, and cannot trade based on undisclosed material information.

Illegal insider trading occurs when an insider trades based on information not available to the public, thereby violating a duty or other relationship of trust and confidence.

Major Analytical Frameworks

Classical Economics

In classical economics, the concept of fair markets and capital formation is crucial. Insider trading impedes these principles by favoring individuals who have access to non-public information, thus creating an uneven playing field.

Neoclassical Economics

Neoclassical economists would argue that insider trading could lead to market inefficiencies. It contravenes the notion of perfectly competitive markets where all participants have equal information.

Keynesian Economics

Keynesian economics focuses on total spending in the economy and its effects on output and inflation. Insider trading could be seen as detrimental because it distorts the capital markets, possibly leading to misallocated resources that do not efficiently contribute to aggregate demand.

Marxian Economics

From a Marxian perspective, insider trading is a manifestation of the deep inequalities inherent in a capitalist system. It exemplifies how the financial elites can manipulate markets to their advantage, perpetuating class inequalities.

Institutional Economics

Institutional economists would examine the rules and norms underpinning market operations and focus on how institutional frameworks can either mitigate or exacerbate insider trading. They would assess the effectiveness of regulatory institutions.

Behavioral Economics

Behavioral economists would study the cognitive biases and emotions that drive insider trading and the reactions of other investors to insider activity. They would investigate how the perception of fairness in markets influences investor behavior.

Post-Keynesian Economics

In Post-Keynesian economics, the focus on the importance of financial stability provides a backdrop to understanding why preventing insider trading is critical. The manipulation and exploitation of privileged information threaten the stability and integrity of financial systems.

Austrian Economics

Austrian economists might criticize the regulations against insider trading as undue interference in the market process. They see market outcomes as the result of human actions and believe that government regulations can often exacerbate problems by creating distortions.

Development Economics

In development economics, fair and transparent markets are considered essential for economic growth and development. Insider trading is a barrier to achieving this, as it hinders access to capital for emerging markets and companies.

Monetarism

Although monetarists primarily focus on the role of government in controlling the amount of money in circulation, safeguarding the integrity of capital markets from practices like insider trading is important to maintain investor confidence and effective market functioning.

Comparative Analysis

Across different economic theories, insider trading is seen primarily as a negative impact on fair market conditions. However, the rationale and emphasis on why it is detrimental can vary significantly. For instance, while classical and neoclassical economics highlight market fairness and efficiency, Marxian and institutional economics focus more on the power dynamics and rules governing economic transactions.
