The author focuses on a method to price Collateralized Debt Obligations (CDO) tranches. The original method is developed by Castagna, Mercurio and Mosconi in 2012. The Thesis provides an extension of the original work by generalizing the Gaussian dependence in terms of Copula functions. In particular the model is rewritten for the specific case of the Clayton copula. The method is applied to price the tranches of a CDX. By comparing the tranches prices, it is possible to notice that the Clayton approach leads to smaller equity and mezzanine tranches. The senior and super senior tranches levels are higher when the dependence is modeled by a Clayton copula.

In global financial centers, short-term market rates are effectively determined in the pledged collateral market, where banks and other financial institutions exchange collateral (such as bonds and equities) for money. Furthermore, the use of long-dated securities as collateral for short tenors—or example, in securities-lending and repo markets, and prime brokerage funding—impacts the risk premia (or moneyness) along the yield curve. In this paper, we deploy a methodology to show that transactions using long dated collateral also affect short-term market rates. Our results suggest that the unwind of central bank balance sheets will likely strengthen the monetary policy transmission, as dealer balance-sheet space is now relatively less constrained, with a rebound in collateral reuse.

Large banks and dealers use and reuse collateral pledged by nonbanks, which helps lubricate the global financial system. The supply of collateral arises from specific investment strategies in the asset management complex, with the primary providers being hedge funds, pension funds, insurers, official sector accounts, money markets and others. Post-Lehman, there has been a significant decline in the source collateral for the large dealers that specialize in intermediating pledgeable collateral. Since collateral can be reused, the overall effect (i.e., reduced ?source' of collateral times the velocity of collateral) may have been a $4-5 trillion reduction in collateral. This decline in financial lubrication likely has impact on the conduct of global monetary policy. And recent regulations aimed at financial stability, focusing on building equity and reducing leverage at large banks/dealers, may also reduce financial lubrication in the nonbank/bank nexus.

We study a dynamic economy where credit is limited by insufficient collateral and, as a result, investment and output are too low. In this environment, changes in investor sentiment or market expectations can give rise to credit bubbles, that is, expansions in credit that are backed not by expectations of future profits (i.e. fundamental collateral), but instead by expectations of future credit (i.e. bubbly collateral). During a credit bubble, there is more credit available for entrepreneurs: this is the crowding-in effect. But entrepreneurs must also use some of this credit to cancel past credit: this is the crowding-out effect. There is an "optimal" bubble size that trades off these two effects and maximizes long-run output and consumption. The “equilibrium” bubble size depends on investor sentiment, however, and it typically does not coincide with the “optimal” bubble size. This provides a new rationale for macroprudential policy. A lender of last resort can replicate the “optimal” bubble by taxing credit when the "equilibrium" bubble is too high, and subsidizing credit when the “equilibrium” bubble is too low. This leaning-against-the-wind policy maximizes output and consumption. Moreover, the same conditions that make this policy desirable guarantee that a lender of last resort has the resources to implement it.
