  1. Reputation and Sudden Collapse in Secondary Markets Discussionby Andy Neumeyer Universidad Torcuato Di Tella

  2. SEC probes second Goldman security From the Financial Times. June 9 2010 23:42 “The US Securities and Exchange Commission has stepped up its inquiries into a complex mortgage-backed deal by Goldman Sachs that was not part of the civil fraud charges filed against the bank in April, according to people close to the matter. SEC interest in Hudson Mezzanine Funding, a $2bn collaterised debt obligation, comes amid settlement talks with Goldman over accusations that the bank defrauded investors in Abacus, a similar CDO.”

  9. Setup of theModel ABS Originator SellsABS Buyer

  10. StaticModel • Secondary market exists iff ABS originator sells (is active) • Perfect information: only costs matter • Assumption on returns

  11. StaticModel • Imperfect information (lemmons): there is trade iff

  12. DynamicModel In t = 2 • New buyer observes payoff of ABS in t = 1 • ABS originator issues ABS with same (π, c) of t = 1 • Beliefs μ2 depend on actions and v realizations in t =1

  13. DynamicModel

  14. Dynamic Model: crucial assumptions • ABS assembled by originator has always the same (π, c) • Otherwise no Bayesian learning → all results collapse • Other interpretation: update about whether the ABS originator truthfully disclosed the distribution • What if the incentives to lie change over time ?

  15. If I taketheModelSeriously . . .

  16. Illustration of abruptcollapses • All ABS collapse in 2007 • Auto ABS, creditcards and studentloans revive in firsthalf of 2008 • Collapse in september 2008

  17. Whydid auto ABS marketcollapse in 2007?

  18. InterestRates ABS Originator SellsABS Buyer

  19. InterestRates (staticmodel) Payoff sell hold r* InterestRate Marketcollapse

  20. InterestRates (DynamicModel) μ MultipleEquilibrium μ0 μ* μ r* InterestRate

  21. InterestRates in thePaper • Whycollapse in 2007 and not in 2001? • More discipline onμ?

  22. Conclusions • Do wethinkthatdistributions of returnson ABS are constantover time across new issuances? • Do more work in terms of matchingmodel and data
