We study stable matchings on exogenously given or endogenously formed bipartite graphs that reflect constraints on matching. The effects of a change of the exogenously given graph (constraints) are investigated. Specifically, we examine to what extent individuals gain or lose from relaxing...

The recent literature on firm-to-firm trade has documented salient empirical regularities of the buyer-seller network … assessment of theoretical models that aim to identify the determinants of firm-to-firm networks in international trade. …

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can … maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors … possibly overlapping projects. We bring our model to the data by analyzing the coauthorship network of economists registered in …

In this paper, we develop a network perspective on the welfare gains from trade in today's internationally fragmented …

We study the formation of networks in environments where agents derive benefits from other agents directly linked to … networks with undirected links (e.g. epidemics, underground resistance organizations, trade networks) where we find that stable … networks are comprised of completely connected disjoint subnetworks. Then, we consider networks with directed links and we find …

This paper applies the toolkit of network analysis to identify the … network properties of international environmental cooperation based on 546 IEAs signed between 1948 and 2015. We identify four …

Many data situations require the consideration of network effects among the cross-sectional units of observation. In … this paper, we present a generalized panel model which accounts for two features: (i) three types of network effects on the … error components, and (ii) higher-order network effects due to ex-ante unknown network-decay functions or the presence of …

Firm-to-firm connections in domestic and international production networks play a fundamental role in economic outcomes …. Firm heterogeneity and the sparse nature of firm-to-firm connections implicitly discipline network structure. We find that … networks. We propose an "elementary" model for production networks based on random matching and firm heterogeneity and …

Bad risks benefit from … having a connection with a good firm, but they are a cost to both direct and indirect connections. In efficient networks the … good risks should form large connected components with very few bad risks attached. The equilibrium networks, on the other …
