모기지유동화증권(Mortgage-Backed Securities:MBS)의 도입과 변화를 주도한 근본적인 원인은 투자자 혹은 차입자의 효용 제고 및 욕구 충족에 있다. 본 연구는 이러한 사실에 주목하여 MBS의 발행 구조에 따라 그 가치가 변동할 수 있음을 이론 모형으로 정립, 증명, 분석 및 해석한다. 구체적으로 자동이체증권과 PAC-Support CMO라는 차별적 발행구조의 두 MBS의 가치를 투자자의 효용의 관점에서 파악하고 발행구조에 따라 후자가 전자보다 더 큰 가치를 창출할 수 있음을 이론적으로 보인다. 한편 모기지 및 MBS의 가치평가에 재금융(refinancing)으로 인한 조기상환 위험의 평가가 매우 중요하며, 재금융은 이자율의 등락 및 과거 이자율의 경로에 의하여 크게 영향 받기 때문에 이를 3기간 모형으로 반영하여 MBS의 가치평가를 시도하였다. 특히 소진현상(burnout)을 모형에 명확히 반영하여 이 현상이 MBS의 현금흐름, 위험 및 가치에 미치는 영향을 고찰하였다. 본 연구 결과 동일한 현금흐름 및 위험을 제시하는 MBS보다 차별적으로 설계된 MBS가 선호될 수 있으며 후자의 가치를 극대화하는 최적의 발행 구조가 존재함이 인정된다.

Abstract

It is frequently said that mortgage-backed securities (MBS) of different security designs are issued in an attempt to meet the varying needs and expectations of investors. If this is true indeed, MBS of complicated risk-return characteristics are likely to be priced higher than MBS of simple risk-return characteristics are. We test this implication by establishing a recombining binomial interest rate prepayment model with a burnout effect embedded. More specifically, we compare the relative values (utilities) of a pass-through and a PAC- Support collateralized mortgage obligation(CMO), and theoretically show why and how the CMO is more highly valued than is the pass-through. The model is established such that mortgage prepayment is a function of the current value of, and the past path of, the mortgage market rate. Since we work on not the total value of the two MBS but the value of each tranche of either MBS, the test results could be robust to slightly different versions of similar tests, which may be done in the future.
