    • Balance in resource allocation problems: a changing reference approach 

      Karsu, Özlem; Erkan, Hale (Springer, 2020)
      Fairness is one of the primary concerns in resource allocation problems, especially in settings which are associated with public welfare. Using a total benefit-maximizing approach may not be applicable while distributing ...
    • Balance in resource allocation problems: a changing reference approach 

      Erkan, Hale (Bilkent University, 2018-05)
      Fairness has become one of the primary concerns in resource allocation problems, especially in settings which are associated with public welfare. Using a pure e ciency maximizing approach may not be applicable while ...
    • The effect of stake size in experimental bargaining and distribution games: a survey 

      Karagözoğlu, E.; Urhan, Ü. B. (Springer, 2017)
      We review the literature on bargaining and distribution experiments to investigate whether changes in stake size have significant effects on behaviour in laboratory/field settings. We conclude that experiments in this field ...
    • The effects of reference points on fairness judgments 

      Akar, Betul (Bilkent University, 2014)
      In this study, we empirically investigate the effects of reference points on fairness judgments with the help of the vignette technique. Specifically, we examine (i) whether reference points have influence on fairness ...
    • Ensuring multidimensional equality in public service 

      Akoluk, Damla; Karsu, Özlem (Elsevier Ltd, 2021-10-23)
      Service planning problems typically involve decisions that lead to the distribution of multiple benefits to multiple users, and hence include equality and efficiency concerns in a multidimensional way. We develop two ...
    • Ensuring multidimensional fairness in public service 

      Akoluk, Damla (Bilkent University, 2020-12)
      In this study, we focus on service planning problems, in which decisions lead to distributions of multiple benefits to multiple users, hence involve fairness and efficiency concerns in a multidimensional way. We develop ...
    • Equitable decision making approaches over allocations of multiple benefits to multiple entities 

      Kaynar, N.; Karsu, Özlem (Elsevier, 2018)
      In this study, we develop decision support tools for policy makers that will help them make choices among a set of allocation alternatives. We assume that alternatives are evaluated based on their benefits to different ...
    • Equitable decision making approaches over allocations of multiple benefits to multiple entities 

      Keleş, Sema Nur Kaynar (Bilkent University, 2017-07)
      In this study, we develop decision support tools for policy makers that will help them make choices among a set of allocation alternatives. We assume that alternatives are evaluated based on their benefits to different ...
    • Fair allocation of personal protective equipment to health centers during early phases of a pandemic 

      Dönmez, Zehranaz; Turhan, S.; Karsu, Özlem; Kara, Bahar Y.; Karaşan, Oya (Elsevier, 2022-05)
      We consider the problem of allocating personal protective equipment, namely surgical and respiratory masks, to health centers under extremely limited supply. We formulate a multi-objective multi-period non-linear resource ...
    • Fair resource allocation: Using welfare-based dominance constraints 

      Argyris, N.; Karsu, Özlem; Yavuz, Mirel (Elsevier, 2022-03-01)
      In this paper we consider the problem of supporting resource allocation decisions affecting multiple beneficiaries. Such problems inherently involve efficiency-fairness trade-offs. We introduce a new approach based on the ...
    • Fair task allocation in crowdsourced delivery 

      Basik, F.; Gedik, B.; Ferhatosmanoglu, H.; Wu, K. (Institute of Electrical and Electronics Engineers, 2018)
      Faster and more cost-efficient, crowdsourced delivery is needed to meet the growing customer demands of many industries. In this work, we introduce a new crowdsourced delivery platform that takes fairness towards workers ...
    • Finding robustly fair solutions in resource allocation 

      Elver, İzzet Egemen (Bilkent University, 2022-07)
      In this study, we consider resource allocation problems where the decisions affect multiple beneficiaries and the decision maker aims to ensure that the effect is distributed to the beneficiaries in an equitable manner. ...
    • In Press, Corrected Proof: Ensuring multidimensional equality in public service 

      Akoluk, Damla; Karsu, Özlem (Elsevier, 2021-10-23)
      Service planning problems typically involve decisions that lead to the distribution of multiple benefits to multiple users, and hence include equality and efficiency concerns in a multidimensional way. We develop two ...
    • Inequity averse optimization in operational research 

      Karsu, Ö.; Morton, A. (Elsevier, 2015)
      There are many applications across a broad range of business problem domains in which equity is a concern and many well-known operational research (OR) problems such as knapsack, scheduling or assignment problems have been ...
    • The influence of distributive justice on lying for and stealing from a supervisor 

      Umphress, E. E.; Ren, L. R.; Bingham, J. B.; Gogus, C. I. (Springer Netherlands, 2009)
      In a controlled laboratory experiment, we found evidence for our predictions that participants who received fair distributive treatment were more likely to lie to give a supervisor a good performance evaluation than those ...
    • Morality in competition law: the culture of honesty and trust in consumer protection 

      Uçaryılmaz, Talya (Athens Institute for Education and Research, 2021-04)
      Recent works in legal scholarship have shifted the focus of competition law to the economic analysis of law. Yet today we face the revival of the fairness concerns in competition polices. This article concerns itself ...
    • A new ex-ante efficiency criterion and implications for the probabilistic serial mechanism 

      Doğan, B.; Doğan, Serhat; Yıldız, Kemal (Academic Press, 2018)
      We introduce and analyze an efficiency criterion for probabilistic assignment of objects, when only ordinal preference information is available. This efficiency criterion is based on the following domination relation: a ...
    • Random access over wireless links: optimal rate and activity probability selection 

      Karakoç, Nurullah (Bilkent University, 2017-07)
      Due to the rapidly increasing number of devices in wireless networks with the proliferation of applications based on new technologies such as machine to machine communications and Internet of Things, there is a growing ...
    • Solution approaches for equitable multiobjective integer programming problems 

      Bashir, Bashir; Karsu, Özlem (Springer, 2022-04)
      We consider multi-objective optimization problems where the decision maker (DM) has equity concerns. We assume that the preference model of the DM satisfies properties related to inequity-aversion, hence we focus on finding ...
