Friendship Network in the Classroom: Parents Bias and Peer Effects
Landini, Fabio; Montinari, Natalia; Pin, Paolo; … - 2014
We interview both parents and their children enrolled in six primary schools in the district of Treviso (Italy). We study the structural differences between the children network of friends reported by children and the one elicited asking their parents. We find that the parents' network has a...

Gender homophily, collaboration, and output
Prummer, Anja; Ductor, Lorenzo - 2023
We consider the implications of gender homophily in Economics, which has persisted despite the significant increase in … women in the field. As women remain underrepresented, gender homophily may serve as a constraint in collaboration. It could …. We show that gender homophily neither constrains collaboration nor prevents higher quality output. …

Community structure and market outcomes: A repeated games in networks approach
Fainmesser, Itay P. - 2010
Consider a large market with asymmetric information, in which sellers choose whether to cooperate or deviate and cheat their buyers, and buyers decide whether to re-purchase from different sellers. We model active trade relationships as links in a buyer-seller network and suggest a framework for...

Coauthorship Networks and Research Output
König, Michael D.; Liu, Xiaodong; Zimmermann, Christian - 2015
We study the impact of research collaborations in coauthorship networks on total research output. Through the links in the collaboration network researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them. We characterize the interior...

Network formation with local complements and global substitutes: The case of R&D networks
Hsieh, Chih-sheng; König, Michael D.; Liu, Xiaodong - 2017
In this paper we introduce a stochastic network formation model where agents choose both actions and links. Neighbors in the network benefit from each other's action levels through local complementarities and there exists a global interaction effect reflecting a strategic substitutability in...

Dynamic R&D networks with process and product innovations
König, Michael D. - 2016
We analyze the endogenous formation of R&D networks, where firms are active in different product markets and can benefit from R&D spillovers form collaborating firms within or across different industries. R&D spillovers help firms to introduce process innovations to lower their production costs....

Fictitious play in networks
Ewerhart, Christian; Valkanova, Kremena - 2016
This paper studies fictitious play in networks of noncooperative two-player games. We show that continuous-time fictitious play converges to Nash equilibrium provided that the overall game is zero-sum. Moreover, the rate of convergence is 1/T , regardless of the size of the network. In contrast,...

Aggregate fluctuations in adaptive production networks
König, Michael D. - 2016
We study production networks where firms' products can be described by a set of input and output characteristics, and links are formed only if the output characteristics of a seller match the input characteristics of a customer. We introduce a fully endogenous network formation model with...
