We solve the problem of optimal securitization for an issuer facing heterogeneous investors with arbitrary time and risk preferences. We show that the optimal securitization is characterized by multiple nonlinear tranches, and each investor gets a portfolio of these tranches. In particular, when...

This paper models the strategic interaction between a rating agency, a banking sector and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating independent capital requirements....

This paper provides evidence on how the new international regulation on Global Systemically Important Banks (G-SIBs) impacts the market value of large banks. We analyze the stock price reactions for the 300 largest banks from 52 countries across 12 relevant regulatory announcement and...

If regulation fails to differentiate between priced and idiosyncratic risk, it incentivizes investors to reach for yield. Studying securitization exposures on the balance sheets of German banks, I show evidence consistent with this prediction. Banks with tight regulatory constraints (low capital...

We study the public loan guarantee programs implemented in Italy in the aftermath of the Covid-19 pandemic. Guided by a theoretical model and relying on a unique loan-level dataset covering the period between December 2019 and March 2021, including both guaranteed and non-guaranteed loans, we...

We compile a rich dataset that links institutional investors' position level holdings with corporate bond characteristics and estimate demand elasticities with respect to critical sources of risk. Persistence in institutions' holdings provide us with an instrument to isolate exogenous movements...

Italian startups financed by venture capitalists (VCs) experience a faster growth in size and become more innovative compared with other startups. VC-backed firms also show a much larger increase in equity and a reduction in their leverage. This evidence is obtained by comparing a representative...
