  • Three public goods and lexicographic preferences : replacement principle 

    Ehlers, Lars (Centre interuniversitaire de recherche en économie quantitative, 2021-03)
    We study the problem of locating multiple public goods for a group of agents with single-peaked preferences over an interval. An alternative specifies for each public good a location. In Miyagawa (1998) each agent consumes only his most preferred ...
  • Normative properties for object allocation problems : characterizations and trade-offs 

    Ehlers, Lars; Klaus, Bettina (Université de Lausanne. École des hautes études commerciales. Département d'économie, 2021-03)
    We consider the allocation of indivisible objects among agents when monetary transfers are not allowed. Agents have strict preferences over the objects (possibly about not getting any object) and are assigned at most one object. How should one allocate ...
  • Strategy-proof and envyfree random assignment 

    Basteck, Christian; Ehlers, Lars (Centre interuniversitaire de recherche en économie quantitative, 2020-12-22)
    We study the random assignment of indivisible objects among a set of agents with strict preferences. We show that there exists no mechanism which is strategy-proof, envyfree and unanimous. Then we weaken the latter requirement to q-unanimity: when ...
  • Strategy-proof choice under monotonic additive preferences 

    Bahel, Eric; Sprumont, Yves (Université de Montréal. Département de sciences économiques., 2020-05)
    We describe the class of strategy-proof mechanisms for choosing sets of objects when preferences are additive and monotonic.
  • Two-stage majoritarian choice 

    Horan, Sean; Sprumont, Yves (Université de Montréal. Département de sciences économiques., 2020-05)
    We propose a class of decisive collective choice rules that rely on an exogenous linear ordering to partition the majority relation into two acyclic relations. The first relation is used to obtain a shortlist of the feasible alternatives while the ...
  • Estimating COVID-19 prevalence in the United States: A sample selection model approach 

    Benatia, David; Godefroy, Raphaël; Lewis, Joshua (Université de Montréal. Département de sciences économiques., 2020-04)
  • Blocking pairs versus blocking students: Stability comparisons in school choice 

    Dogan, Battal; Ehlers, Lars (Université de Montréal. Département de sciences économiques., 2020-04)
    It is known that there are school choice problems without an efficient and stable assignment. We consider comparing assignments in terms of their stability by comparing their sets of blocking (student-school) pairs or comparing their sets of blocking ...
  • Spouses, children and entrepreneurship 

    Galindo da Fonseca, Joao; Berubé, Charles (Université de Montréal. Département de sciences économiques., 2020-04)
    We develop a model of endogenous entrepreneurship and marriage. Spouses influence entrepreneurship via three channels: they reduce benefits by working less the more profitable the business is, they reduce costs by working more in case of business ...
  • Robust minimal instability of the top trading cycles mechanism 

    Doğan, Battal; Ehlers, Lars (Université de Montréal. Département de sciences économiques., 2020-03)
    In the context of priority-based resource allocation, we formulate methods to compare assignments in terms of their stability as binary relations (on the set of possible assignments) that depend on the preference and the priority profile. We introduce ...
  • The growth impact of language standardization : Metcalfe’s Law and the industrial revolution 

    Dudley, Léonard; Rauh, Christopher (2020-01-13)
    During the Industrial Revolution, did population growth stimulate innovation, or did causality run primarily from innovation to growth? Previous research fails to explain why between 1700 and 1850: (i) most innovation originated in three clusters of ...
  • Non-manipulable house exchangeunder (minimum) equilibrium prices 

    Andersson, Tommy; Ehlers, Lars; Svensson, Lars-Gunnar (Lund University. Department of economics, 2020)
    We consider a market with indivisible objects, called houses, and money. On this market, each house is initially owned (or rented) by some agent and each agent demands precisely one house. The problem is to identify the complete set of direct allocation ...
  • Imposing equilibrium restrictions in the estimation of dynamic discrete games 

    Aguirregabiria, Victor; Marcoux, Mathieu (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 limitations. MPEC guarantees local ...
  • Measuring uncertainty at the regional level using newspaper text 

    Rauh, Christopher (Université de Montréal. Département de sciences économiques., 2019-08)
    In this paper I present a methodology to provide uncertainty measures at the regional level in real time using the full bandwidth of news. In order to do so I download vast amounts of newspaper articles, summarize these into topics using unsupervised ...
  • Unemployment, entrepreneurship and firm outcomes 

    Galindo da Fonseca, Joao (Université de Montréal. Département de sciences économiques., 2019-05)
    Are there differences between firms created by unemployed individuals relative to otherwise identical employed individuals? The answer is crucial for understanding the impact of policies that promote entrepreneurship among the unemployed. I develop an ...
  • The housing boom and selection into entrepreneurship 

    Galindo da Fonseca, Joao; Pannella, Pierluca (Université de Montréal. Département de sciences économiques., 2019-05)
    We provide evidence that the boom in housing prices occurred in the early 2000 distorted the selection of individuals that opened a business. A simple model of collateral financing predicts an increase in entry into entrepreneurship for house-owners ...
  • Entrepreneurship, outside options and constrained 

    Galindo da Fonseca, Joao; Snoddy, Iain (Université de Montréal. Département de sciences économiques., 2019-05)
    The literature on search frictions has often adopted the assumption of free entry. In this paper we forgo of this restriction by proposing a more realistic framework in which individuals are constantly making the decision whether or not to open a firm. ...
  • Spouses and entrepreneurship 

    Galindo da Fonseca, Joao; Berube, Charles (Université de Montréal. Département de sciences économiques., 2019-05)
    Does having a spouse influence an individual’s decision to start a firm and what firms they create? The answer to this question is crucial for our understanding of how recent changes to family composition influence firm creation. We develop a model of ...
  • The hard problem of prediction for conflict prevention 

    Mueller, Hannes; Rauh, Christopher (Université de Montréal. Département de sciences économiques., 2019-04)
    There is a rising interest in conflict prevention and this interest provides a strong motivation for better conflict forecasting. A key problem of conflict forecasting for prevention is that predicting the start of conflict in previously peaceful ...
  • Games with unobservable heterogeneity and multiple equilibria: an application to mobile telecommunications 

    Marcoux, Mathieu (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 unobserved heterogeneity ...
  • Sharp test for equilibrium uniqueness in discrete games with a flexible information structure 

    Marcoux, Mathieu (Université de Montréal. Département de sciences économiques., 2018-12)
    I propose a test for an assumption commonly maintained when estimating static discrete games of incomplete information, i.e. the assumption of equilibrium uniqueness in the data generating process. The test is appealing for several reasons. It allows ...
