In search of efficient network structures: the needle in the haystackSpringer Science and Business Media LLC - Tập 11 - Trang 339-359 - 2007
Nicolas Carayol, Pascale Roux, Murat Yıldızoğlu
Searching for efficient networks can prove a very difficult analytical and even computational task. In this paper, we explore the possibility of using the genetic algorithms (GA) technique to identify efficient network structures in the case of non-trivial payoff functions. The robustness of this method in predicting optimal networks is tested on the two simple stylized models introduced by Jackso...... hiện toàn bộ
On the existence of an increasing symmetric equilibrium in (k + 1)-st price common value auctionsSpringer Science and Business Media LLC - Tập 10 - Trang 63-71 - 2006
Ilia Tsetlin, Aleksandar Saša Pekeč
In a classical result, Milgrom (1981a) established that the Monotone Likelihood Ratio Property (MLRP) is a sufficient condition for the existence of an increasing symmetric equilibrium in (k + 1)-st price common value auctions. We show: (1) If MLRP is violated, then for any number of bidders and objects there exists a distribution of the common value such that no increasing symmetric equilibrium e...... hiện toàn bộ
Collusion and turnover in experience goods marketsSpringer Science and Business Media LLC - Tập 23 - Trang 91-111 - 2019

We study an infinite horizon duopoly with identical long-lived firms and a sequence of short-lived consumers. Consumers are willing to pay more for a higher-quality good, but quality is a noisy function of the firm’s unobserved effort, and it cannot be observed by consumers prior to purchase. We show that a duopoly can overcome this moral hazard problem, and that it can outperform a monopoly in te...... hiện toàn bộ
Innovation contests with temporary and endogenous monopoly rentsSpringer Science and Business Media LLC - Tập 12 - Trang 189-208 - 2008
Frederik Schmidt
In this article, a Tullock contest success function is used to model an innovation contest with endogenous innovation height. We can prove stability for this endogenous prize contest. The winner of the contest gains a monopoly rent, which has two dimensions. In the first dimension the winning firm influences the innovation height. The second dimension is the life span of the temporary monopoly. Th...... hiện toàn bộ
Health and fairness with other-regarding preferencesSpringer Science and Business Media LLC - Tập 24 - Trang 123-141 - 2020
Aitor Calo-Blanco
This paper explores how to rank social allocations when individuals have other-regarding preferences (ORPs). Unlike the few existing studies on this issue, we focus on two different private goods, only one of which generates ORPs concerns. Specifically, individuals exhibit other-regarding views about the social health state but have standard self-centered preferences over other goods, namely consu...... hiện toàn bộ
