Boundedly rational opinion dynamics in social networks : does indegree matter?

Battiston, Pietro; Stanca, Luca M. - 2015

This paper investigates opinion dynamics and social influence in directed communication networks. We study the theoretical properties of a boundedly rational model of opinion formation in which individuals aggregate the information they receive from their neighbors by using weights that are a...

International trade and financial integration : a weighted network analysis

Fagiolo, Giorgio (contributor); Reyes, Javier (contributor); … - 2007

In this paper we compare the patterns of trade and financial integration by exploiting network analysis. Our results show that, by combining binary and weighted network analysis, it is possible to deliver more precise and thorough insights on the topological structure and properties of the...

Migration and trade : a complex-network approach

Fagiolo, Giorgio; Mastrorillo, Marina - 2013

This paper explores the relationships between migration and trade using a complex-network approach. We show that: (i) both weighted and binary versions of the networks of international migration and trade are strongly correlated; (ii) such correlations can be mostly explained by country...

Estimating the elasticity of trade : the trade share approach

Lanati, Mauro - 2013 - March 2013, revised April 2013

Recent theoretical work on international trade emphasizes the importance of trade elasticity as the fundamental statistic needed to conduct welfare analysis. Eaton and Kortum (2002) proposed a two-step method to estimate this parameter, where exporter fixed effects are regressed on proxies for...

The international-trade network : gravity equations and topological properties

Fagiolo, Giorgio - 2009

This paper begins to explore the determinants of the topological properties of the international - trade network (ITN). We fit bilateral-trade flows using a standard gravity equation to build a “residual” ITN where trade-link weights are depurated from geographical distance, size, border...

Modeling the international-trade network : a gravity approach

Dueñas, Marco; Fagiolo, Giorgio - 2011

This paper investigates whether the gravity model (GM) can explain the statistical properties of the International Trade Network (ITN). We fit data on international-trade flows with a GM specification using alternative fitting techniques and we employ GM estimates to build a weighted predicted...
