Background
Discrete choice models are essential tools in economics and related fields for analyzing decisions where the outcomes are discrete and categorical in nature. These models help to understand choices made by individuals or organizations among a set of mutually exclusive alternatives.
Historical Context
Discrete choice models gained prominence in the mid to late 20th century. Their development was fueled by the need to accurately capture decision-making processes where the choice is not continuous but occurs in discrete leaps, such as choosing between different brands, modes of transportation, or policy options.
Definitions and Concepts
Discrete choice models refer to a range of regression models with categorical dependent variables. These categories are distinct and non-overlapping. Such models typically use probability theory to estimate the likelihood of an individual choosing a particular category based on influencing factors.
Major Analytical Frameworks
Classical Economics
While classical economics primarily focuses on continuous variables and market equilibria, discrete choice models provide an essential tool for analyzing specific choices at the micro-level within classical frameworks.
Neoclassical Economics
Neoclassical economics has actively incorporated discrete choice models into utility maximization problems, facilitating the analysis of consumer choice behavior and demand systems.
Keynesian Economics
Discrete choice models assist Keynesian economists in understanding consumer and business choices under conditions of uncertainty, complementing macroeconomic models of aggregate demand.
Marxian Economics
In Marxian analysis, discrete choice models can help to dissect distributional aspects of consumption and the dynamics of labor markets within capitalist economies.
Institutional Economics
Institutional economists use discrete choice models to account for the role of various social, legal, and political institutions in shaping economic choices.
Behavioral Economics
These models are particularly useful in behavioral economics, providing a quantifiable means to investigate how cognitive biases and heuristics influence decision-making.
Post-Keynesian Economics
Post-Keynesian economists utilize discrete choice models to study how individual and collective choices interact with price rigidities and other market imperfections.
Austrian Economics
In the Austrian tradition, discrete choice models can assist in examining the entrepreneurial selection processes and market dynamics from an individual’s subjective standpoint.
Development Economics
These models are vital in development economics to understand choices related to education, health, employment, and other critical dimensions influencing development outcomes.
Monetarism
In monetarism, discrete choice models help analyze the individual decisions impacting money supply and demand, essential for understanding broader monetary policies.
Comparative Analysis
Comparatively, discrete choice models encompass a range of methods such as the *logit and *probit models. Each offers nuanced advantages; *logit models are computationally simpler, while *probit models presume a normal distribution of errors which can suit specific empirical situations better.
Case Studies
Case studies employing discrete choice models include market analysis scenarios for choosing products or services, mode choice in transportation planning, and evaluating policy impacts where public choice behavior must be assessed.

Related Terms with Definitions
- Logit Model: A type of regression model used for predicting the probability of a binary outcome.
- Probit Model: Similar to the logit model, but assumes a normal distribution of the error term.
- Categorical Variable: A variable that can take on a limited number of fixed, non-numeric values representing different categories.
