Securitization under Asymmetric Information over the Business Cycle

CERGE-EI Working paper 506, 2014

Abstract: This paper studies the efficiency of financial intermediation through securitization in a model with heterogenous investment projects and asymmetric information about the quality of securitized assets. I show that, in general, when retaining part of the risk, the issuer of securitized assets may credibly signal its quality. However, in boom stages of the business cycle this practice is inefficient, information on asset quality remains private, and lower quality assets accumulate on balance sheets. This prolongs and deepens a subsequent downturn with an intensity proportional to the length of the preceding boom. I present empirical evidence from securitization deal-level data consistent with this result. In recessions, the model also produces amplification of adverse selection problems on re-sale markets for securitized assets. These are especially severe after a prolonged boom period and when securitized assets of high-quality are no longer traded. Finally, this general equilibrium model suggests that improperly designed regulation requiring higher explicit risk-retention may become counter-productive, i.e., may adversely affect both quantity and quality of investment in the economy.

Fragility of Resale Markets for Securitized Assets and Policy of Asset Purchases
Previous title: Adverse Selection in Resale Markets for Securitized Assets
Bank of Canada Staff Working Paper 2016-46

Abstract: Markets for securitized assets were characterized by high liquidity prior to the recent financial crisis and by a sudden market dry-up at the onset of the crisis. A general equilibrium model with heterogeneous investment opportunities and information frictions predicts that, in boom periods or mild recessions, the degree of adverse selection in resale markets for securitized assets is limited because of the reputation-based guarantees by asset originators. This supports investment and output. However, in a deep recession, characterized by high dispersion of asset qualities, there is a sudden surge in adverse selection due to an economy-wide default on reputation-based guarantees, which persistently depresses the output in the economy. Government policy of asset purchases limits the negative effects of adverse selection on the real economy, but may create a negative moral hazard problem.

In or Out: Do Bail-In Bonds Really Decrease Bailouts? (with Kinda Hachem)

Abstract: Bail-in bonds have gained a lot of attention among bank regulators. These bonds supposedly raise the hurdle for a government bailout by converting into loss-absorbing capital once the issuing bank runs into trouble. We argue that banks can short-circuit bail-in requirements by offering investors off-balance-sheet insurance against conversion. The bond itself appears as a bail-in bond on the issuer's balance sheet while the insurance is booked off balance sheet until the bond converts. The government can deter insurance provision by imposing penalties when insurance is discovered, but these penalties may not be credible. We find conditions for an equilibrium in which insurance against conversion is provided by banks and bailed out by the government rather than penalized upon discovery. We also present new empirical evidence in support of our model.

Asset Pricing with Durable Goods and External Habit Formation (with Michal Pakoš)

Abstract: We propose a model which tries to explain in a unified framework both time and cross-section variation in the conditional asset pricing moments on the stock market. We combine two strands of literature on asset pricing: external habit formation and literature on asset pricing where investors' large share of consumption consists of service flows from stock of durable goods. We develop a theoretical model as a generalization of Campbell and Cochrane (1999) external habit formation model, where we introduce durable goods and estimate its parameters using the GMM methodology on the set of 6 Fama-French portfolios. The estimated weight of durables in the utility function is significantly different from zero.

Securitization under Asymmetric Information and Macro-prudential Regulation

Abstract: This paper presents a small scale DSGE model where banking sector raises deposits, participates in the interbank market and issues and trades securitized products. The model contains externality related to bank failures the costs of which are not fully internalized by banks and asymmetric information related to securitization process which give rise to adverse selection problems and which are most severe in a recession. But similarly as in Kuncl (2014) the inefficiencies build-up mainly in the boom stage of the business cycle. The presence of externality justifies the introduction of macro-prudential regulation. I study the effect of various macro-prudential tools on the welfare.
