Sommario del corso
The course introduces students to the essential elements of decision theory, expected utility theory, game theory and their applications to important phenomena in modern society (e.g., altruistic behavior, the concept of fairness, the breakdown of negotiations, emergence and decline of social norms). More broadly, the course familiarizes students with modern theories of instrumental rationality which are contrasted to empirical evidence and rivalling philosophical theories of rationality (e.g., Kantian accounts).
Risultati dell'apprendimento attesi
At the end of the course, the students possess a clear understanding of "rational decisions" and "rational behavior", and the scope and limits of the theories that describe them. They understand the technical foundations of rational choice theory and game theory, can evaluate these models critically, and apply them to real-world problems.
Part I: Individual Rationality and Decision Theory
Week 1 and 2 (first class): The concept of rationality and utility in the British philosophy of the 18th and 19th century (Hume, Bentham, Mill), and its impact on the modern formulation.
Week 2 (second class) and Week 3: Modern decision theory in the axiomatic formulation by von Neumann/Morgenstern and Savage, based on the concept of rational preferences. Challenges to that view (Allais paradox, Ellsberg paradox).
Part II: Interactive Rationality and Game Theory
Week 4: Introduction to game theory and its central concepts such as dominant strategy, the Nash equilibrium. Different kinds of Nash equilibria (e.g., pure and randomized ones), and their interpretations.
Week 5: Applying game theory to explaining altruistic behavior cooperation. Criticism and limitations of game theory. The evolutionary interpretation of game theory.
Week 6: The emergence, maintenance and decay of social norms from the perspective of game theory. Norms vs. conventions.
Time permitting, we will also discuss problems of social choice (e.g., Arrow's impossibility theorem for collective preferences) and judgment aggregation.
