Stem cell legislation and its impact on the geographic preferences of stem cell researchers KU Leuven
Systemic risk from investment similarities KU Leuven
Network theory proved recently to be useful in the quantification of many properties of financial systems. The analysis of the structure of investment portfolios is a major application since their eventual correlation and overlap impact the actual risk by individual investors. We investigate the bipartite network of US mutual fund portfolios and their assets. We follow its evolution during the Global Financial Crisis and study the ...
Projects, institutional logics and institutional work practices: The case of the Lucca Comics & Games Festival KU Leuven
© 2018 Elsevier Ltd, APM and IPMA This paper investigates the relations between festivals and their institutional settings, and how these relations shape festival management. We analyze institutional logics and work practices in a complex project, Lucca Comics & Games, which is the biggest festival dedicated to fantasy culture in Italy. Our results, based on archival research, media coverage and interview data, reveal the recursive interplay ...
The similarity of global value chains: A network-based measure KU Leuven
© Copyright Cambridge University Press 2018. International trade has been increasingly organized in the form of global value chains (GVCs). In this paper, we provide a new method for comparing GVCs across countries and over time. First, we use the World Input-Output Database (WIOD) to construct both the upstream and the downstream global value networks. Second, we introduce a network-based measure of node similarity to compare the GVCs between ...
The network of migrants and international trade KU Leuven
© 2018, Springer International Publishing AG, part of Springer Nature. This paper investigates the relationship between international trade and migration with the specific aim of estimating direct and indirect effect of the latter on cross-border flows of both homogeneous and differentiated goods. Adopting a spatial econometric approach along with a gravity model set-up, we account for the role of ethnic communities in neighbouring countries on ...
Sailing in all winds: Technological search over the business cycle KU Leuven
© 2018 Elsevier B.V. Business cycles modify firms’ incentives to innovate and the direction of innovation. By introducing a new measure of patent unconventionality this paper explores the impact of the business cycle on firms’ technological search strategies. We find that during upturns firms generate inventions characterized by a higher level of technological unconventionality. We also find that financially resilient and diversified firms ...
Systemic risk in the global water input-output network KU Leuven
© 2018 Elsevier B.V. The issue of water access and security has been emphasized in the recent policy debate on sustainable development (Sustainable Development Goal No. 6) and adaptation to climate change (CoP21 in Paris, 2015). This study provides new evidence about the Blue Virtual Water Input-Output Network. The main novelty of our approach is the combination of Structural Decomposition Analysis (SDA) with Network Theory. SDA reveals that ...
Random walks on the world input-output network KU Leuven
© The authors 2017. Published by Oxford University Press. All rights reserved. Modern production is increasingly fragmented across countries.To disentangle theworld production system at sector level, we use the World Input-Output Database to construct the World Input-Output Network (WION) where the nodes are the individual sectors in different countries and the edges are the transactions between them. In order to explore the features and ...
Consistency and trends of technological innovations: A network approach to the international patent classification data KU Leuven
© Springer International Publishing AG 2018. Classifying patents by the technology areas they pertain is important to enable information search and facilitate policy analysis and socio-economic studies. Based on the OECD Triadic Patent Family database, this study constructs a cohort network based on the grouping of IPC subclasses in the same patent families, and a citation network based on citations between subclasses of patent families citing ...
