Network Formation Preliminary and Incomplete
نویسنده
چکیده
I study a network based mechanism of norm enforcement in a community where agents play a Prisoner’s Dilemma with changing partners. Agents may choose a number of close friends. Communication to close friends within the network enforces cooperation. In a world with noiseless communication, it is optimal that each agent has close contacts to all other network members. Moreover, it is optimal to have a huge network size. If communication is noisy a lower number of close contacts is optimal. As the number of network members gets large and network members receive noisy information from all network members, norm enforcement fails. JEL Classification Numbers:

Complete / Incomplete Hierarchical Hub Center Single Assignment Network Problem
In this paper we present the problem of designing a three level hub center network. In our network, the top level consists of a complete network where a direct link is between all central hubs. The second and third levels consist of star networks that connect the hubs to central hubs and the demand nodes to hubs and thus to central hubs, respectively. We model this problem in an incomplete net...
متن کاملDesigning Incomplete Hub Location-routing Network in Urban Transportation Problem
In this paper, a comprehensive model for hub location-routing problem is proposed which no network structure other than connectivity is imposed on backbone (i.e. network between hub nodes) and tributary networks (i.e. networks which connect non-hub nodes to hub nodes). This model is applied in public transportation, telecommunication and banking networks. In this model locating and routing is c...
متن کاملDesign of a Bi-Objective Capacitated Single-Allocation Incomplete Hub Network Considering an Elastic Demand
This paper presents a bi-objective capacitated hub arc location problem with single assignment for designing a metro network with an elastic demand. In the literature, it is widely supposed that the network created with the hub nodes is complete. In this paper, this assumption is relaxed. Moreover, in most hub location problems, the demand is assumed to be static and independent of the location...
متن کاملPreliminary Version: Habit Formation in Consumption: Estimation Results for the U.S. and the Euro Area
This paper analyzes habit formation in consumption for the demand block of a small-scale macro model as in Fuhrer (2000). The applied empirical method of indirect inference provides a limited information strategy for estimating a partial equilibrium model. Preliminary estimates of the model parameters for the United States and for the Euro Area are presented, confirming the importance of habit ...
متن کاملDynamic Network Formation with Incomplete Information
How do networks form and what is their ultimate topology? Most of the literature that addresses these questions assumes complete information: agents know in advance the value of linking to other agents, even with agents they have never met and with whom they have had no previous interaction (direct or indirect). This paper addresses the same questions under what seems to us to be the much more ...
