Background
The term “principal” in economics commonly refers to either an individual or a firm that employs an agent to carry out specific tasks or functions on their behalf. This concept is foundational in the study of agency theory, which explores the dynamic between principals and agents.
Historical Context
The principal-agent terminology has its roots in contract theory and the broader field of economics and business. The relationship between principal and agent has been discussed for centuries, but it became a central topic of importance with the formalization of agency theory in the late 20th century.
Definitions and Concepts
Principal
-
Principal: A person or a firm that employs another, known as an agent, to undertake tasks on their behalf. This typically involves delegation of duties such as selling property, investing capital, or managing an organization.
-
Principal-Agent Problem: This is a challenging issue in economics and business that arises when agents (those employed to perform tasks) may not always act in the best interests of the principals (those who employ them). Instead, agents might pursue their own goals, which can sometimes conflict with those of the principals.
Major Analytical Frameworks
Classical Economics
Classical economists address principal-agent relationships through traditional notions of contracts and employment, without deeply delving into the complexities of informational asymmetry.
Neoclassical Economics
Neoclassical economics delves into principal-agent problems using models that incorporate perfect competition and rational behavior, stressing on outcomes that optimize welfare for both parties.
Keynesian Economics
Keynesian economic theory often implies a more macroeconomic outlook, focusing less on micro-level relationships like that between a principal and an agent.
Marxian Economics
Marxian economic theory would see the principal-agent relationship as a manifestation of class struggles, where the principal represents capital owners and the agent represents the labor force.
Institutional Economics
Institutional economists emphasize the formal and informal rules governing the principal-agent relationship, looking at how various institutions can mitigate or exacerbate principal-agent problems.
Behavioral Economics
Behavioral economics examines how real-life deviations from rational behavior by principals and agents affect outcomes, incorporating insights from psychology to offer a more nuanced understanding of agent behavior.
Post-Keynesian Economics
Post-Keynesians may critique the power dynamics inherent in the principal-agent relationship and may consider how economic policies can alter these dynamics for societal benefit.
Austrian Economics
Austrian economists emphasize the importance of information, market processes, and the decentralization of decision-making, framing the principal-agents’ issues within the context of larger market processes.
Development Economics
Development economics looks at the principal-agent problem through the lens of economic development, focusing on how agents (often government officials or international organizations) can be incentivized to act in the interests of the broader population (the principals).
Monetarism
Monetarists typically focus on the implications of principal-agent issues within financial institutions and markets, examining how monetary policy can mitigate agency problems in banking and finance.
Comparative Analysis
Understanding the principal-agent problem requires analyses from different economic perspectives, each providing unique insights into the nature of incentives, information asymmetry, moral hazard, and adverse selection.
Case Studies
Real Estate Transactions
In real estate, the principal-agent problem can manifest when an agent—motivated by commission—pushes a client to buy or sell property quickly rather than securing the best terms.
Corporate Management
In corporations, shareholders (principals) must ensure that managers (agents) act to maximize shareholder value and not follow their own interests.

By considering different economic perspectives and contextual applications, one can better understand the intricacies of the principal-agent relationship in both theoretical and practical terms.
