Background
Discriminatory Analysis refers to a statistical method used to classify observations into distinct groups or categories based on a set of attributes. It aims to minimize the probability of misclassification and correctly allocate an individual or observation to its respective group.
Historical Context
Discriminatory analysis, which has its roots in statistics and econometrics, gained prominence with the development of early classification algorithms and methodologies in the 20th century. It has evolved alongside advancements in computational power and data analytics, becoming an essential tool in both fields.
Definitions and Concepts
Discriminatory analysis involves defining multiple discriminatory functions for various categories. These functions, being linear combinations of the variables or attributes, are used to distinguish between different groups. Coefficients for these functions are estimated using a training set, a representative sample of past observations.
Major Analytical Frameworks
Classical Economics
Though not traditionally covered by classical economic theory, discriminatory analysis can be tangentially related to labor segregation and markets.
Neoclassical Economics
Neoclassical Economics may use discriminatory analysis in decision making models, risk assessments, and optimization problems.
Keynesian Economics
Keynesian models do not typically emphasize statistical classification; however, discriminatory analysis might be applied in policy simulations that require categorizing regions, industries or demographic segments.
Marxian Economics
From a sociological perspective, discriminatory analysis might serve as a tool to highlight or research systemic biases and labor exploitation.
Institutional Economics
This branch often explores the role of human behavior and organizational norms. Discriminatory analysis can be valuable in categorizing institutional responses or behaviors.
Behavioral Economics
Discriminatory analysis can be significant in understanding consumer behavior, categorizing types of irrationalities, and market segmentation based on behavioral traits.
Post-Keynesian Economics
Although the primary focus is on overall economic stability, discriminatory analysis can assist in streamlining market interventions by categorizing economic units.
Austrian Economics
Generally skeptical of heavy reliance on quantitative analysis, Austrian Economics may involve discriminatory analysis to critique central economic planning initiatives or market segmentations.
Development Economics
Discriminatory analysis aids in understanding categories of economic development, regional disparities, and targeted policy impacts.
Monetarism
Monetarist policies emphasized targeting and classification which discriminatory analysis can significantly support, particularly in targeting monetary interventions.
Comparative Analysis
Comparing discriminatory analysis across these various schools of thought and quantitative models demonstrates its flexibility and applicability in a diverse set of economic issues ranging from labor markets to consumer behavior and policy assessment.
Case Studies
Typical applications range from clustering individuals in market research to categorizing financial assets for risk assessment. For instance, during financial crises, classes of distressed banks can be identified using discriminatory analysis.
