  10. Potential Returns: Old System Place $100,000 in savings account: Deposit earns 1% interest $ 1,000 profit Home loan, owner does not default: principal $100,000 interest $ 20,000 Total payments $120,000 $20,000 profit Home loan, owner defaults: Sell property $ 40,000 $60,000 loss

  11. Strong Incentive to Check Creditworthiness If you do not pay for a credit check: Borrower is not a good risk; you do make the loan: −$60,000 Borrower is a good risk; you do make the loan: +$20,000 If you do pay for credit check ($5,000) Borrower is not a good risk; loan is not made: −$ 5,000 Borrower is a good risk; you do make the loan: $20,000 profit – $5,000 credit check +$15,000

  12. Purchased mortgage, no default without credit check: with credit check : Purchased mortgage without credit check, default: $120,000 $120,000 $40,000 $100,000 $100,000 $100,000 $0 $0 $5,000 $15,000 $20,000 −$60,000

  13. The Mortgage–Backed Security • Mortgages are bundled together and then pieces are sold off to investors. • Why do this? • Spreads risk • Increases liquidity • Allows small investors to participate • More money flows into the housing sector

  14. Securitization Split into 10 shares $50,000 $50,000 $50,000 $50,000 $50,000 $50,000 $50,000 $50,000 $50,000 $50,000 Mortgage #1 Mortgage #2 Mortgage #3 Mortgage #4 Mortgage #5 $500,000

  15. If no homeowners default: principal $100,000 interest $ 20,000 Total payments $120,000 X 5 = $600,000 ÷ 10 $60,000 ‒$50,000 cost / share $10,000 profit / share If one homeowner defaults: 4 X $120,000= $480,000 Home sale $ 40,000 $520,000 ÷ 10 $ 52,000 ‒$50,000 cost / share $2,000 profit / share Consequences of default are spread across all 10 investors

  16. Old System: Concentrated Risk Strong incentive to check creditworthiness because the negative consequences of default to any single investor were large. New System: Dispersed Risk Less incentive to check creditworthiness because the negative consequences of default to any single investor are small.
