This paper presents a model of endogenous network formation in the presence of peer effects for a general class of payoff functions with local complementarities in effort levels and positive local externalities. Links are one-sided and agents move simultaneously. I find that equilibrium networks...

This paper presents a game-theoretic model of network formation, which allows agents to enter bilateral alliances and to extract payoffs from enemies. Each pair of agents creates a surplus of one, which allies divide in equal parts. If agents are enemies, then the agent with more allies obtains...

This paper studies a central bank's optimal interest rate corridor choice in the presence of an endogenous interbank network. We first provide a characterization of the unique equilibrium of banks' liquidity holdings for any network of credit lines. Then, we endogenize the network and show that...

I propose a game of signed network formation, where agents make friends to coerce payoffs from enemies with fewer friends. The model accounts for the interplay between friendship and enmity. Nash equilibrium configurations are such that, either everyone is friends with everyone, or agents can be...

This paper presents a simple model of strategic network formation with local com- plementarities in effort levels and positive local externalities. Equilibrium networks display - other than the complete and the empty network - a core-periphery structure, which is commonly observed in empirical...

In the analysis of microarray data, and in some other contemporary statistical problems, it is not uncommon to apply hypothesis tests in a highly simultaneous way. The number, N say, of tests used can be much larger than the sample sizes, n, to which the tests are applied, yet we wish to...

This article addresses the issue of termination of employment because of the conduct of the employee in her leisure time, in the light of the human right to private life. It explores the impact on the retention of employment of activities taking place outside the workplace and outside working...
