This paper proposes a way to a risk quantification of public sector comparator in the value-for-money test of the BTL (Build-Transfer-Lease) scheme in rail investment projects. Two principal risks that are project delay and budget increasing costs are identified and are empirically quantified with a case study of the Haman-Jinju link. The methodology suggested is expected to be a good reference for the similar research afterwards and also to help in settling down the scheme that is only an early stage.

One of key success factors in PPI(Public Private Investment) is the structure of risk sharing between the public and the private, and the determination mechanism of fair return to private participants relative to the risk that private participants undertake. In Korea, two basic types of PPI exist. One is BTO and the other is BTL. In BTO, most risks are taken by the private whereas the opposite is the case in BTL. No intermediate form exists. As a result, BTO type projects had difficulty in attracting private participants because of the excessive risks. In this study, one intermediate form is studied where demand risk is shared between the public and the private. In the setting where the public authority takes all the project revenues and then pays ladder type payments to private participants depending upon the level of project revenues, appropriate level of fixed payments is endogenously derived using the real option pricing model. From the fixed payments, expected investment returns are calculated based upon a certain distributional assumption. The results of this study is expected to help introducing diverse forms of PPI in Korea.

PFI(Private Finance Initiative) for suppling SOC and public facilities instead of Government Infrastructure Project introduced from 1994. BTO(Build-Transfer-Operate) project had been major type of PFI system from 1994 to 2005. But after changed the Law of PFI on SOC, the BTL project newly introduced. In BTO system, the Government retrieves the investment through the operating income, but in BTL system, the government lease the facilities. As the BTO and BTL projects are widely adopted and implemented to ease the fiscal burden of government, but it has caused the tremendous fiscal burden each year over the period operation. Therefore this study attempted to analyze the question, that is, why government fiscal burden tipping? Hence, this paper, compares the difference of business structure between BTO and BTL project and explore the vicious and virtuous business structure, with the method of circular causal loop analysis. As a result, it has shown that there are some positive feedback and negative feedback loops cause the tipping and easing of government fiscal burden.

This study is about whether the new Project Finance scheme called "Asset Backed Short Term Bond(ABSTB)" with Project Finance Guarantee Cover provided by Korean Exim Bank(KEXIM) is an appropriate and valid financing structure, through close examinations on domestic and overseas IPP case studies. This study clearly indicates that (i) the interest rate of ABSTB with KEXIM's Project Finance Guarantee is relatively more competitive than the interest rate of other ABSTB guaranteed by EPC Companies (ii) the lower credit rated EPC companies make higher ROE(Return on Equity) through this financing structure. Lastly, Korean EPC Companies can secure profitability through this innovative financing scheme which will also lead to winning more power plant Contracts and become globally competitive.

School is a basic and the most fundamental facility of city planning just like other basic public facilities including the village office. Every plan is established on the basis of school. However, the problems such as the population reduction resulting from the nuclear family-zation and low birth rate, employment and welfare of the aged people resulting from "the old aged society", and the infant nursing and education resulting from a rapid increase of the working couples become notable and accordingly more requirements are being made. Reflecting this trend, the concept and operation system should be changed. Up to now, the BTL projects of the educational facilities are gaining a reputation of being efficient in terms of national budget running, but at the same time receiving negative reputation in terms of budget saving under the civil creativity and efficiency. Through upgrading the private sector investment projects into the BTO+BTL system and further into the BTO(Build Transfer Operate), we can accomplish the original goals of the private sector investment projects, and can make the education budget operation more efficient, and can greatly improve the education environments. However, we should not underestimate in this process that these facilities should not negatively affect the education environments. In any situation, the owners of schools are students.

Koran Government introduced BTL(Build-Transfer-Lease) to provide convenience through early supplying infrastructure and plans to invest 8,315million dollar to 84 projects of 15 BTL type involving official residence and railroad. But some of construction company hates to invest BTL projects because of its low earning rate. In addition if we correctively apply project which partly has profitability to BTL, the earnning rate declines more seriously. So this paper presents BTL+BTO model which operates BTL in the non-profitable parts to improve convenience of users and BTO in the profitable parts to improve earning rate. BTL+BTO model based on operate period was presented and its suitability was confirmed by applting 00 region official residence project.
