CES Economic Theory Seminar

Home 

The Economic Theory workshop is a weekly seminar taking place on fridays 12-13h at the Maison des Sciences Economiques (106-112 Boulevard de l'Hôpital). This seminar is a venue for theoretical work in Economics and for work drawing on quantitative methods in Economics. Defined by an approach rather than by a specific theme, the topics of the seminar can concern a variety of areas in Economics, such as (non exhaustively), micro economics, game theory, mathematical economics, decisions theory, finance or macro economics. The seminar functions as an internal workshop but also regularly greets speakers from other institutions.

Organizers: Emily Tanimura, Stéphane Zuber, Anna Bogomolnaia and Hervé Moulin,

It is supported by the Centre d'économie de la Sorbonne, CNRS and Université Paris 1 Panthéon-Sorbonne.

Title:  Does Quantum Randomness Have Distinctive Features for Economists to Exploit? Demystifying quantum probability, but not quantum phyics

Location: Maison des Sciences Économiques, room S17. 

Summary:  Quantum randomness has been used to power lotteries, and it lies behind quantum computing. It also features in some recent models in economics, finance, and psychology. Yet fundamental questions regarding quantum probability and its relation to classical probability are still being resolved. In their theory of subjective probability, Anscombe and Aumann distinguish between: (i) roulette lotteries, in which different risky outcomes occur with “objective” or hypothetical probabilities; (ii) horse lotteries, in which different uncertain outcomes occur with “subjective” probabilities. Here it is shown that a typical experiment in non-relativistic quantum mechanics can be modelled, at least when the range set of possible measurement outcomes is finite, as a “quantum measurement tree”. In its simplest form, this takes as given a finite-dimensional complex Hilbert space of wave vectors. It then combines three stages: (a) an experimenter's choice of what gets measured, represented in the single-variable case by a self-adjoint matrix; (b) a horse lottery that determines a subjective “density matrix” or, equivalently, a classical probability measure over an orthogonal decomposition of the Hilbert space; (c) a roulette lottery that determines a real-valued measurement outcome, with classical probabilities given by applying Born's trace rule for calculating conditional expectations given the density matrix.
