  • Athey, Susan; Ellison, Glenn (Wiley Blackwell, 2014-04)
    This paper considers a dynamic model of the evolution of open-source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers ...
  • Ellison, Glenn; Swanson, Ashley Terese (American Economic Association, 2010)
    This paper uses a new data source, American Mathematics Competitions, to examine the gender gap among high school students at very high achievement levels. The data bring out several new facts. There is a large gender gap ...
  • Ellison, Glenn (American Economic Association, 2013-07)
    A large literature following Hirsch (2005) has proposed citation- based indexes of individuals' research output. This paper views Hirsch's index as one member of a larger class and examines how well different indexes align ...
  • Ellison, Glenn (John Wiley & Sons, Inc., 2011-03)
    Over the past decade, there has been a decline in the fraction of papers in top economics journals written by economists from the highest-ranked economics departments. This paper documents this fact and uses additional ...
  • Athey, Susan; Ellison, Glenn (Harvard University by the MIT Press, 2011)
    This paper examines a model in which advertisers bid for "sponsored-link" positions on a search engine. The value advertisers derive from each position is endogenized as coming from sales to a population of consumers who ...
  • Ellison, Glenn; Fudenberg, Drew; Imhof, Lorens A. (Elsevier, 2008-05)
    This paper studies the effect of randomness in per-period matching on the long-run outcome of non-equilibrium adaptive processes. If there are many matchings between each strategy revision, the randomness due to matching ...
  • Ellison, Glenn; Wolitzky, Alexander (Rand Corporation, 2012-10)
    This paper develops search-theoretic models in which it is individually rational for firms to engage in obfuscation. It considers oligopoly competition between firms selling a homogeneous good to a population of rational ...
  • Ellison, Glenn; Ellison, Sara F. (American Economic Association, 2011-02)
    This paper develops a new approach to testing for strategic entry deterrence and applies it to the behavior of pharmaceutical incumbents before patent expiration. It examines a cross section of markets, determining whether ...
  • Ellison, Glenn; Ellison, Sara F. (American Economic Association, 2009-08)
    Data on memory modules sales are used to explore aspects of e-retail demand. Aggregate sales are examined in state-level regressions. Discrete choice techniques are used to examine (incomplete) hourly sales data from a ...
  • Ellison, Glenn; Holden, Richard (Oxford University Press, 2013-11)
    This article develops a model with endogenously coarse rules. A principal hires an agent to take an action. The principal knows the optimal state-contingent action, but cannot communicate it perfectly due to communication ...
  • Ellison, Glenn; Glaeser, Edward L.; Kerr, William R. (American Economic Association, 2010-06)
    Why do firms cluster near one another? We test Marshall's theories of industrial agglomeration by examining which industries locate near one another, or coagglomerate. We construct pairwise coagglomeration indices for US ...
