Intermediation has been a centerpiece of policy discussions since the financial crisis. Given the complexity of financial institutions, various tools has been used to study different aspects of intermediation. This talk focuses on two: network models and search models. In the first part, I develop a network model of the financial sector in which endogenous intermediation among debt financed banks generates excessive systemic risk. I show that a core-periphery network few highly interconnected and many sparsely connected banks endogenously emerges in sty model. In the second part, I use a search model to study a frictional asset market where ex-ante homogeneous traders irreversibly choose their contact rate and then periodically meet in pairs. We use the model to explore the distributional properties of financial institution: we prove that the contact rate distribution has a Pareto tail with parameter two and that middlemen emerge endogenously: a zero measure of traders choose to have continuous contact with the market and account fors positive fraction of all meetings. I compare the properties of socially efficient and equilibrium allocation in both models.
