We use the universe of USPTO data on patents and inventors from 1976 to 2019 to look at the dynamics of coauthorship on patents and its relationship with competition. First, we find an inverted-U relationship between competition and the growth in coauthorship: the number of new collaborators on...

In this paper, we examine possible types of network formation among immigrants in the diaspora and between those immigrants and the locals in different countries. We present the model by considering different possible interactions between immigrants and the new society in their host country....

The restrictive measures that have been imposed from March 2020 on business activities in several countries to reduce the spread of the COVID-19 pandemic can be interpreted as shocks to global supply chains. We propose some agent-based models to evaluate the economic effects of different...

Capturing financial network linkages and contagion in stress test models are important goals for banking supervisors and central banks responsible for micro- and macroprudential policy. However, granular data on financial networks is often lacking, and instead the networks must be reconstructed...

We examine how trade sanctions can be imposed effectively in a trading network. We focus on three factors that affect trade sanctions: a country’s endowment, distance between trading countries, and connectivity in the network. Our models explain several empirical observations: (i) sanctions...

The literature is characterized by a lack of research analyzing cross-border mergers and acquisitions (CBM&A) as a network. This article aims to evaluate the topology properties (the geographical and sectoral structure) of the global CBM&A network in 1990-2021. A quantitative study is conducted...

In this paper, we examine possible types of network formation among immigrants in the diaspora and between those immigrants and the locals in different countries. We present the model by considering different possible interactions between immigrants and the new society in their host country....

This paper assesses whether cross-border M&A decisions exhibit network effects. We estimate exponential random graph models (ERGM) and temporal exponential random graph models (TERGM) to evaluate the determinants of cross-country M&A investments at the sectoral level. The results show that...

This paper explores the manner in which the structure of a social network constrains the level of inequality that can be sustained among its members. We assume that any distribution of value across the network must be stable with respect to coalitional deviations, and that players can form a...
