Markets for heterogeneous products: A boundedly rational consumer model

Valente, Marco - 2009

The paper is based on the acknowledgement that properties of markets stemming from features of demand are too frequently overlooked in the economic literature, and a re-balancing is necessary to properly account for theoretical and empirical phenomena. We sustain that one of the most relevant...

Quantifying knowledge spillovers from advances in negative emissions technologies

Tripodi, Giorgio; Lamperti, Francesco; Mavilia, Roberto; … - 2022

Negative emissions technologies (NETs) feature prominently in most scenarios that halt climate change and deliver on the Paris Agreement's temperature goal. As of today, however, their maturity and desirability are highly debated. Since the social value of new technologies depends on how novel...

Synchronization of endogenous business cycles

Pangallo, Marco - 2023

Business cycles tend to comove across countries. However, standard models that attribute comovement to propagation of exogenous shocks struggle to generate a level of co-movement that is as high as in the data. In this paper, we consider models that produce business cycles endogenously, through...

Identifying the community structure of the international-trade multi network

Barigozzi, Matteo; Fagiolo, Giorgio; Mangioni, Giuseppe - 2010

We study the community structure of the multi-network of commodity-specific trade relations among world countries over the 1992-2003 period. We compare structures across commodities and time by means of the normalized mutual information index (NMI). We also compare them with exogenous community...

Using complex network analysis to assess the evolution of international economic integration: The cases of East Asia and Latin America

Reyes, Javier; Schiavo, Stefano; Fagiolo, Giorgio - 2007

Over the past four decades the High Performing Asian Economies (HPAE) have followed a development strategy based on the exposure of their local markets to the presence of foreign competition and on an outward oriented production. In contrast, Latin American Economies (LATAM) began taking steps...

The evolution of the world trade web

Fagiolo, Giorgio; Reyes, Javier; Schiavo, Stefano - 2007

This paper employs a weighted network analysis to study the empirical properties of the world trade web and their evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large number of strong relationships, thus...

Collateral unchained: Rehypothecation networks, concentration and systemic effects

Luu, Duc Thi; Napoletano, Mauro; Barucca, Paolo; … - 2018

collateral flows are concentrated among few nodes (like in core-periphery networks) allow large increases in collateral volumes … Value-at-Risk (VaR) criterion, and we then study the emergence of collateral hoarding cascades in different networks. Our … hoarding cascades following local shocks. These networks are therefore characterized by a trade-off between liquidity and …

A multi-scale model of virus pandemic: Heterogeneous interactive entities in a globally connected world

Bellomo, Nicola; Bingham, Richard D.; Chaplain, Mark A. J. - 2020

This paper is devoted to the multidisciplinary modelling of a pandemic initiated by an aggressive virus, specifically the so-called SARS-CoV-2 Severe Acute Respiratory Syndrome, corona virus n.2. The study is developed within a multiscale framework accounting for the interaction of different...

A multiscale network-based model of contagion dynamics: Heterogeneity, spatial distancing and vaccination

Aguiar, Maíra; Dosi, Giovanni; Knopoff, Damián A.; … - 2021

Lockdown and vaccination policies have been the major concern in the last year in order to contain the SARS-CoV-2 infection during the COVID-19 pandemic. In this paper we present a model able to evaluate alternative lockdown policies and vaccination strategies. Our approach integrates and...
