Link or Languish? A Long‐Run Empirical Analysis of Production Network Positioning, Embeddedness and Growth
Production networks influence economic outcomes through several channels. On the one hand, linkages within such networks enhance productivity and have been pivotal for development. On the other hand, integration into Global Value Chains (GVCs) can drive economic upgrading. This paper provides a comprehensive empirical analysis of these mechanisms over the long run. Using a long‐run multi‐country input–output dataset (1965–2014), we trace the orig…
Investigating resilience of refugee households in Jordan
As of 2024, Jordan hosts over 1.3 million refugees—one of the highest refugee-to-host population ratios globally—posing significant challenges for sustaining refugee household livelihoods. To inform effective support strategies, this study quantifies household resilience using quarterly UNHCR data from 2022. We conceptualize resilience as the ability to maintain a minimum, normatively defined level of well-being when exposed to potential stressor…
On the employment and health impact of the Covid-19 shock on Italian regions
We evaluate the exposure of Italian regions to employment and the health risk associated with the spread of COVID-19. First, we estimate the degree of participation of Italian regions in a plurality of value chains linked to consumption, investment and exports. Second, we investigate the different levels of contagion risk associated with each value chain and the possibility of reducing such risk through remote work. We find that regions are affec…
On the Coevolution Between Social Network Structure and Diffusion of the Coronavirus (Covid-19) in Spatial Compartmental Epidemic Models
In this article, the author studies epidemic diffusion in a spatial compartmental model, where individuals are initially connected in a social or geographical network. As the virus spreads in the network, the structure of interactions between people may endogenously change over time, due to quarantining measures and/or spatial-distancing (SD) policies. The author explores via simulations the dynamic properties of the coevolutionary process linkin…
Specialization in food production affects global food security and food systems sustainability
How do countries specialize in agricultural production? A complex network analysis of the global agricultural product space
Using a complex-network perspective, this paper empirically explores the determinants of the process through which countries, given their capabilities, specialize in agricultural production. Using production data from the Food and Agriculture Organization (FAO) for the period 1993–2013, we characterize the agricultural production space as a time-sequence of bipartite networks, connecting countries to the agricultural products they produce. We the…
Identifying the community structure of the food-trade international multi-network
Achieving international food security requires improved understanding of how international trade networks connect countries around the world through the import-export flows of food commodities. The properties of international food trade networks are still poorly documented, especially from a multi-network perspective. In particular, nothing is known about the multi-network's community structure. Here we find that the individual crop-specific laye…
How do people choose their commuting mode? An evolutionary approach to travel choices
Distance-varying assortativity and clustering of the international trade network
In this paper, we study how the topology of the International Trade Network (ITN) changes in geographical space, and along time. We employ geographical distance between countries in the world to filter the links in the ITN, building a sequence of subnetworks, each one featuring trade links occurring at similar distance. We then test if the assortativity and clustering of ITN subnetworks changes as distance increases, and we find that this is inde…

Macroeconomic Policy in DSGE and Agent-Based Models Redux
The Great Recession seems to be a natural experiment for economic analysis, in that it has shown the inadequacy of the predominant theoretical framework -the New Neoclassical Synthesis (NNS) -grounded on the DSGE model. In this paper, we present a critical discussion of the theoretical, empirical and politicaleconomy pitfalls of the DSGE-based approach to policy analysis. We suggest that a more fruitful research avenue should escape the strong th…
The influence of climate variability on internal migration flows in South Africa
Human-mobility networks, country income, and labor productivity
This paper asks whether the level of integration of world countries in the international network of temporary human mobility can explain differences in their per-capita income and labor productivity. We disentangle the role played by global country centrality in the network from traditional openness measures, which only account for local, nearest-neighbor linkages through which ideas and knowledge can flow. Using 1995-2010 data, we show that glob…
Spatial Localization in Manufacturing
Vitali S., Napoletano M. and Fagiolo G. Spatial localization in manufacturing: a cross-country analysis, Regional Studies. This paper employs a homogeneous-firm database to investigate industry localization in European countries. More specifically, it compares, across industries and countries, the predictions of two of the most popular localization indexes, that is, the Ellison and Glaeser index of 1997 and the Duranton and Overman index of 2005.…

Modeling industrial evolution in geographical space
In this article we study a class of evolutionary models of industrial agglomeration with local positive feedbacks, which allow for a wide set of empirically testable implications. Their roots rest in the Generalized Polya Urn framework. Here, however, we build on a birth-death process over a finite number of locations and a finite population of firms. The process of selection among production sites that are heterogeneous in their ‘intrinsic attra…
