Precision may harm: The comparative statics of imprecise judgement
(Université de Montréal. Département de sciences économiques., 2018-08)
We consider an agent whose information about the objects of choice is imperfect in two respects: first, their values are perceived with ‘error’; and, second, the realised values cannot be discriminated with absolute ...
Imposing equilibrium restrictions in the estimation of dynamic discrete games
(Université de Montréal. Département de sciences économiques., 2019-09)
Imposing equilibrium restrictions provides substantial gains in the estimation of dynamic discrete games. Estimation algorithms imposing these restrictions – MPEC, NFXP, NPL, and variations – have different merits and ...
Belief-weighted Nash aggregation of Savage preferences
(Université de Montréal. Département de sciences économiques., 2018-09)
The 'belief-weighted Nash social welfare functions' are methods for aggregating Savage preferences defined over a set of acts. Each such method works as follows. Fix a 0-normalized subjective expected utility representation ...
Single-Peaked Choice
(Université de Montréal. Département de sciences économiques., 2006-09)
Single-peaked preferences have played an important role in the literature ever since they were used by Black (1948) to formulate a domain restriction that is sufficient for the exclusion of cycles according to the majority ...
Non-Deteriorating Choice without Full Transitivity
(Université de Montréal. Département de sciences économiques., 2006-08)
Although the theory of greatest-element rationalizability and maximal-element rationalizability under general domains and without full transitivity of rationalizing relations is well-developed in the literature, these ...
Random consideration and choice: A case study of «default» options
(Université de Montréal. Département de sciences économiques., 2018-11)
A growing number of stochastic choice models include a “default” option for situations where the decision maker selects none of the feasible alternatives. While this is a welcome development, these models also present an ...
Threshold Luce rules
(Université de Montréal. Département de sciences économiques., 2018-11)
In the late 1950’s, Luce proposed two different theories of imperfect utility discrimination that have had a lasting impact on economics. One model (1956) gave rise to the literature on just noticeable differences while ...
Flippable Pairs and Subset Comparisons in Comparative Probability Orderings and Related Simple Games
(Université de Montréal. Département de sciences économiques., 2006-10)
We show that every additively representable comparative probability order on n atoms is determined by at least n - 1 binary subset comparisons. We show that there are many orders of this kind, not just the lexicographic ...
Innovation growth clusters : Lessons from the industrial revolution
(Université de Montréal. Département de sciences économiques., 2018-08)
Over three centuries ago, a new technology suddenly increased the amount and frequency of available information. Might such «Big Data» have disrupted the causal relationships linking economic growth and innovation? Previous ...
Games with unobservable heterogeneity and multiple equilibria: an application to mobile telecommunications
(Université de Montréal. Département de sciences économiques., 2019-02)
To shed light on the limited success of competition enhancing policies in mobile telecommunications, I estimate a game of transceivers’ locations between national incumbents and a new entrant in Canada. I recover player-specific ...
