Key research themes
1. How do violations of classical rationality principles inform extended models of preferential choice?
This research theme investigates empirical violations of normative consistency principles (such as transitivity and independence of irrelevant alternatives) that define classical rationality in choice theory. It examines the nature and robustness of these violations, their interrelationships, and adaptive functions, leading to the development of descriptive models that extend beyond classical rational choice assumptions. The theme addresses the implications of bounded rationality and stochastic transitivity in understanding human preferential behavior, advancing theories that reconcile systematic inconsistencies with reasonable adaptation to environmental constraints.
2. What are the methodological and conceptual critiques of classical rational choice theory and how do they inform alternative frameworks?
This theme focuses on critiques of classical rational choice theory from multiple disciplinary perspectives including economics, sociology, cultural theory, and decision science. It explores conceptual limitations such as unrealistic assumptions about preference consistency, computational capacity, and subjective rationality. The theme elaborates on bounded rationality, cultural influences, organizational constraints, and cognitive factors that question the universal applicability of classical rational choice models. Alternative frameworks emphasize adaptive heuristics, behavioral inconsistencies, and social structural effects, aiming to offer more empirically valid and context-sensitive models of human decision-making and social behavior.
3. How can voting rules and social choice mechanisms be characterized and reconciled with axioms of rationality and fairness?
This theme analyzes the axiomatic foundations of collective decision-making rules, particularly voting methods, focusing on their consistency with principles such as independence of irrelevant alternatives, expansion consistency, anonymity, neutrality, and resoluteness. It explores impossibility theorems highlighting tensions among these axioms and investigates alternative frameworks (like the Advantage-Standard model) that weaken or revise classical constraints to evade impossibility results. Characterizations include the role of majority margins in determining outcomes and the design of voting rules that maintain desirable normative properties while accommodating empirical and logical constraints.
