This study assesses the network structures of cross-shareholdings among listed Japanese companies using a dataset of 2,936 companies for fiscal years 2008-2015. First, we analyze the network structure of cross-shareholdings in the Japanese stock market using centrality measures. Financial...

In a wide variety of social settings (e.g. crime, education, political activism, technology adoption), players' returns to their efforts depend on how much effort others exert. Modeling these situations as a network game with strategic complementarities, we show that a player's cycle centrality...

This paper studies the impact of collaboration on research output. First, we build a micro founded model for scientific knowledge production, where collaboration between researchers is represented by a bipartite network. The equilibrium of the game incorporates both the complementarity effect...

This paper develops a model of intermediated exchange with budget-constrained traders who are embedded in a trading network. An experimental investigation confirms the theory's baseline predictions. Traders adopt monotone strategies with higher-budget intermediaries offering to pay more for...

We study systemic illiquidity using a unique data set on UK banks' daily cash flows, short-term interbank funding and liquid asset buffers. Failure to roll-over short-term funding or repay obligations when they fall due generates an externality in the form of systemic illiquidity. We simulate a...

We study the incentives that agents have to invest in costly protection against cascading failures in networked systems. Applications include vaccination, computer security and airport security. Agents are connected through a network and can fail either intrinsically or as a result of the...

Recent empirical evidence suggests that financial networks exhibit a core-periphery network structure. This paper aims at giving an explanation for the emergence of such a structure using network formation theory. We propose a simple model of the overnight interbank lending market, in which...

We introduce a general model for the balance-sheet consistent valuation of interbank claims within an interconnected financial system. Our model represents an extension of clearing models of interdependent liabilities to account for the presence of uncertainty on banks' external assets. At the...

Whereas in some industries retailers distribute the products of all suppliers, in other industries they differentiate themselves from their rivals by becoming the exclusive distributors of some products, which results in incomplete distribution networks. To study this phenomenon, I analyze a...

We introduce a version of the Cumulative Offer Algorithm of Hatfield and Milgrom(2005) modified for the supply chain networks setting of Ostrovsky (2008). The algorithmprovides an alternative proof for existence of a chain stable network. Moreover, we show that when choice functions satisfy...
