Recently a variety of link-based stability concepts have emerged in the literature on game theoretic models of social network formation.We investigate two basic formation properties that establish equivalence between some well known types of stable networks and their natural extensions.These...

Three metrics are designed to assess Colombian financial institutions’ size,<br/>connectedness and non-­substitutability as the main drivers of systemic<br/>importance: (i) centrality as net borrower in the money market network;<br/>(ii) centrality as payments originator in the large-value payment...

We consider a relational economy in which economic agents participate in three types of relational economic activities: autarkic activities; binary matching activities; and plural cooperative activities. We introduce a stability notion and characterize stable interaction structures, both in the...

Yang s theory of economic specialization under increasing returns to scale (Yang 2001) is a formal development of the fundamental Smith-Young theorem on the extent of the market and the social division of labor.In this theory specialization and, thus, the social division of labor is firmly...

Abstract: We study the impact of corporate networks on the takeover process. We find that better connected companies are more active bidders. When a bidder and a target have one or more directors in common, the probability that the takeover transaction will be successfully completed augments,...

We study a financial network characterized by the presence of depositors, banks and their shareholders. Belonging to a financial network is beneficial for both the depositors and banks' shareholders since the return to investment increases with the number of banks connected. However, the network...

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...

An interacting network coupling financial institutions’ multiplex (i.e. multi-layer) and financial market infrastructures’ single-layer networks gives an accurate picture of a financial system’s true connective architecture. We examine and compare the main properties of Colombian multiplex...

We consider a network economy in which economic agents are connected within a structure of value-generating relationships. Agents are assumed to be able to participate in three types of economic activities: autarkic self-provision; binary matching interactions; and multi-person cooperative...

Abstract Constitutions are commonly described as national products shaped by domestic politics. This paper develops and empirically tests a different hypothesis, which is that constitutions are also shaped by transnational influence, or “diffusion”. Constitutional rights can diffuse through...
