What is The Standard Economic Model In Behavioral Economics?

What is the Standard Economic Model?

The Standard Economic Model (SEM) is a fundamental framework in economics, which assumes that individuals are rational, self-interested, and utility-maximizing agents. It posits that people have complete information about their preferences, the available options, and the consequences of their choices. In the SEM, decision-makers are characterized by consistent preferences and transitivity, which means that if they prefer option A over B, and B over C, they must also prefer A over C. The model assumes that individuals have perfect foresight, are able to accurately calculate probabilities, and make decisions based on the expected utility of various options. The SEM serves as a foundation for economic theories, including the principles of supply and demand, market equilibrium, and the efficient allocation of resources.

Examples of the Standard Economic Model

  • Consumer Choice Theory

    Consumer choice theory is a prime example of the Standard Economic Model in action. The theory assumes that consumers are rational and seek to maximize their utility by choosing the optimal combination of goods and services within their budget constraints.

  • Profit-Maximizing Firms

    According to the SEM, firms are rational entities that seek to maximize profits by producing goods and services at the lowest possible cost, given the constraints imposed by technology and input prices. This assumption underpins the analysis of competitive markets and the determination of supply and demand.

Shortcomings and Criticisms of the Standard Economic Model

  • Limited Rationality

    One of the main criticisms of the Standard Economic Model is its assumption of perfect rationality. In reality, individuals often have bounded rationality, which means they are unable to process all available information and instead rely on cognitive shortcuts or heuristics to make decisions. This can lead to seemingly irrational behavior, inconsistent preferences, and decision-making errors.

  • Ignoring Social and Psychological Factors

    The SEM has been criticized for failing to account for social and psychological factors that influence decision-making, such as emotions, social norms, and cognitive biases. By not incorporating these factors, the model may not accurately predict or explain real-world economic behavior.

  • Overemphasis on Self-Interest

    Another criticism of the SEM is its assumption that individuals are solely driven by self-interest. This assumption overlooks the role of altruism, social preferences, and other motivations that can influence decision-making and lead to cooperative behavior or actions that benefit others at the expense of the individual’s own utility.
