A multi-tournament environment is analyzed, focusing on the impact of organizer market structure on agent entry behavior. Two high ability agents first decide which tournament to enter (with fields then filled by low ability agents). If the marginal benefit of high ability agents in an event is...

The pandemic leap continues and only makes things worse. Sharp criticism continues to pour in about what measures it can put in place to reduce the social crisis. Although some have accused the restrictions of being relaxed (lockdown), it does not improve human nature, which instinctively...

Brands investigate cultural sensitivity in order to stand out from global market competition and reach more diverse customers. The research emphasized on the relationship between consumer ethnocentrism, cultural sensitivity and brand credibility toward purchase intention to domestic products....

We provide a theoretical foundation for analyzing how social stigma and adopted behavioral traits affect the transmission of HIV across a population. We combine an evolutionary game-theoretic model-based on a relationship signaling stage game-with the SIR (susceptible-infected-recovered) model...

One cannot doubt the ubiquitous lack of hope and confidence in the so-called democratic institutions by the large majority of people. The fundamental reason thereof is the blatant contradiction between the principle of democracy, promoting the rule of law and thereby the welfare of people, and...

This paper presents an infinite-horizon version of intergenerational utilitarianism. By studying discounted utilitarianism as the discount factor tends to one, we obtain a new welfare criterion: limit-discounted utilitarianism (LDU). We show that LDU meets the standard assumptions of efficiency,...

We study Pareto efficient mechanisms in matching markets when the number of agents is large and individual preferences are randomly drawn from a class of distributions, allowing for both common and idiosyncratic shocks. We provide a broad set of circumstances under which, as the market grows...

Distributional constraints are common features in many real matching markets, such as medical residency matching, school admissions, and teacher assignment. We develop a general theory of matching mechanisms under distributional constraints. We identify the necessary and sufficient condition on...

Games that appear to be independent, involving none of the same players, may be related by emotions of reciprocity between the members of the same groups. In the real world, individuals are members of groups and want to reward or punish those groups whose members have been kind or unkind to...

In this paper we look for a solution to a land division problem that could be applied to different types of disputes when the arbitrator has a very limited information about the agents' preferences. The solution must be fair and efficient under the constraint of the limited information available...
