  • Variable selection for a categorical varying-coefficient model with identifications for determinants of Body Mass Index 

    Gao, J; Peng, B; Ren, Z; Zhang, X (Institute of Mathematical Statistics (IMS), 2017-07-20)
    Obesity has become one of the major public health issues during the last three decades. A considerable number of determinants have been proposed for body mass index (BMI) by a large range of studies from multiple disciplines. ...
  • Visibility and activity: foreign affairs think tanks in the United Kingdom 

    Medina-Iborra, Iván; Guttormsen, David S.A. (University of Manchester, 2013)
    If politics is about transforming ‘reality’, then think tanks are in the business of interpreting politics. However, there is a lack of research dealing with the way think tanks disseminate ideas. Although think tanks are ...
  • Vote or shout 

    Chakravarty, Surajeet; Kaplan, Todd R. (Walter de Gruyter, 2010-09)
    We examine an environment with n voters each with a private value over two alternatives. We compare the social surplus of two mechanisms for deciding: majority voting and shouting, that is, the voter who shouts the loudest ...
  • Voting and the economic cycle 

    Maloney, John; Pickering, Andrew (Springer, 2014)
    Sophisticated voters assess incumbent competence by filtering out economic cycles (which they do not like) from trend growth (which they do). Naive voters on the other hand respond only to raw economic growth. This implies ...
  • When is a time series I(0)? 

    Davidson, James (University of Exeter, 2008)
  • When is ambiguity-attitude constant? 

    Eichberger, Jürgen; Grant, Simon; Kelsey, David (Springer, 2012)
    This paper studies how updating affects ambiguity attitude. In particular we focus on generalized Bayesian updating of the Jaffray-Philippe sub-class of Choquet Expected Utility preferences. We find conditions for ambiguity ...
  • Where strategic and evolutionary stability depart - a study of minimal diversity games (working paper) 

    Demichelis, Stefano; Vermeulen, Dries; Balkenborg, Dieter (University of Exeter Business School, 2010)
    A minimal diversity game is an n player strategic form game in which each player has m pure strategies at his disposal. The payoff to each player is always 1, unless all players select the same pure strategy, in which case ...
  • Where strategic and evolutionary stability depart – a study of minimal diversity games 

    Balkenborg, Dieter; Vermeulen, Dries (INFORMS (Institute for Operations Research and Management Sciences), 2015-12-21)
    A minimal diversity game is an n player strategic form game in which each player has m pure strategies at his disposal. The payoff to each player is always 1, unless all players select the same pure strategy, in which case ...
  • Which way to cooperate 

    Kaplan, Todd R.; Ruffle, Bradley J. (Wiley, 2007-06)
    Cooperation in real-world dilemmas takes many forms. We introduce a class of two-player games that permits two distinct ways to cooperate in the repeated game. One way to cooperate is to play cutoff strategies, which rely ...
  • Why are trade agreements regional? 

    Zissimos, Ben (Blackwell, 2011)
    This paper shows how distance may be used to coordinate on a unique equilibrium in which trade agreements are regional. Trade agreement formation is modeled as coalition formation. In a standard trade model with no distance ...
  • Why banks should keep secrets 

    Kaplan, Todd R. (Springer, 2006-02)
    We show that it is sometimes efficient for a bank to commit to a policy that keeps information about its risky assets private. Our model, based upon Diamond-Dybvig (1983), has the feature that banks acquire information ...
  • Will any gossip do? Gossip does not need to be perfectly accurate to promote trust 

    Fonseca, MA; Peters, K (Elsevier, 2017-10-09)
    The fact that gossip can be inaccurate, intentionally or otherwise, has led to questions over its ability to build cooperation in large societies. We explore the impact of gossip accuracy on trust and trustworthiness in a ...
  • The wisdom of crowds: predicting a weather and climate-related event 

    Hueffer, Karsten; Fonseca, Miguel A.; Leiserowitz, Anthony; Taylor, Karen M. (Society for Judgment and Decision Making, 2013-03)
    Environmental uncertainty is at the core of much of human activity, ranging from daily decisions by individuals to long-term policy planning by governments. Yet, there is little quantitative evidence on the ability of ...
  • Women's entrepreneurship and intimate partner violence: A cluster randomized trial of microenterprise assistance and partner participation in post-conflict Uganda (SSM-D-14-01580R1) 

    Green, EP; Blattman, C; Jamison, J; Annan, J (Elsevier, 2015-03-28)
    Intimate partner violence is widespread and represents an obstacle to human freedom and a significant public health concern. Poverty alleviation programs and efforts to economically “empower” women have become popular ...
  • World commodity prices and domestic retail food inflation: some insights from the UK 

    Davidson, J; Halunga, A; Lloyd, TA; McCorriston, S; Morgan, W (Wiley, 2016-09-01)
    We address the links between world commodity prices and retail food price inflation, focussing on two aspects. First, since world commodity prices represent a relatively small share of costs of retail food products, retail ...
  • World price shocks, income, and democratization 

    Zissimos, Ben (Oxford University Press, 2015-04-12)
    This paper shows how a world price shock can increase the likelihood that democratization must be used to resolve the threat of revolution. Initially, a ruling elite may be able to use trade policy to maintain political ...
