Consumer Behaviour

Background

Consumer behaviour encompasses the economic actions taken by individuals or households regarding the allocation of their incomes to various goods and services. Fundamental to understanding consumer behaviour is recognizing the underlying motivations, preferences, and constraints that guide these economic decisions.

Historical Context

The study of consumer behaviour has evolved over time, drawing from various disciplines including psychology, sociology, and economics. Early economic models emphasized rational decision-making, but later developments incorporated more nuanced views reflecting actual consumer patterns and external influences such as advertising.

Definitions and Concepts

Consumer behaviour refers to the decision-making processes and actions that consumers undertake in order to utilize their incomes. Typically, economic theory assumes several points about consumer behaviour:

Rationality: Consumers are assumed to be rational beings with full awareness of their wants and the means to satisfy them.
Utility Maximization: Consumers are believed to act in ways that maximize their preferences or utility functions under given constraints.
Satisficing: An alternative to utility maximization, this concept suggests that consumers often settle for “good enough” options, repeating satisfactory purchases until faced with issues or dissatisfaction.
Trial and Error: Consumers may explore new products through a process of trial and error, adapting their behaviour based on their experiences.
Influence of Advertising: As consumers may not always follow a fixed utility function, advertisements can play a significant role in shaping their purchasing decisions.

Major Analytical Frameworks

Classical Economics

Classical theories generally postulate that consumers are rational actors who make decisions to maximize their utility based on the availability of information and given budget constraints.

Neoclassical Economics

Neoclassical economics further refines the classical views, advocating for mathematical modeling to predict consumer behavior through concepts like indifference curves and budget lines.

Keynesian Economic

Keynesian economics places greater importance on aggregate demand and thus examines consumer behaviour in the context of broader economic policies and fluctuations.

Marxian Economics

Marxian perspectives would critique the external economic pressures forcing consumer choices, including the roles of capitalism and class structure in determining consumption patterns.

Institutional Economics

Institutional economics emphasizes the impact of institutions, social norms, and legal constraints on consumer behavior, exploring how these external factors shape economic decision-making.

Behavioral Economics

Behavioral economics challenges the notion of fully rational consumers, incorporating psychological insights to explain anomalies and deviations from traditional economic models, such as heuristics and biases.

Post-Keynesian Economics

Post-Keynesian economics integrates elements like real-time adjustments and imperfect information to understand consumer behaviour, focusing on the dynamic and often unpredictable nature of economic decision-making.

Austrian Economics

Austrian economics prioritizes the individual’s subjective values and knowledge, emphasizing the dispersed nature of information and the role of entrepreneurial discovery in shaping economic actions.

Development Economics

Development economists study consumer behaviour within the context of economic development, focusing on how limited resources and varying economic stages influence consumption decisions.

Monetarism

Monetarist views would focus on the influence of monetary policy and financial conditions on consumer behaviour, examining how changes in inflation and interest rates guide consumption patterns.

Comparative Analysis

Different schools of thought provide varied explanations for consumer behaviour. While classical and neoclassical frameworks highlight rationality and utility maximization, behavioral economics and other heterodox models consider more complex, sometimes irrational, motivations.
