实物期权方法在船舶投资决策中的应用

本文旨在把实物期权的思想用于船舶投资决策,建立基于实物期权的船舶投资决策方法。首先介绍了投资决策方法发展过程和基于实物期权的投资决策方法应用现状,并分析了实物期权方法应用于投资决策的优点。然后论述了实物期权方法应用于船舶投资决策的可行性,提出了实物期权方法应用于船舶投资决策的具体步骤,最后利用船舶投资的实例证明了实物期权的价值及优越性。可见实物期权的投资决策方法充分体现了柔性管理的价值,更接近于实际情况,因而与传统的投资决策方法相比有很大的优越性。

从净现值法的基本假设出发，首先分析净现值法在水运建设项目经济评价中存在的问题，指出用净现值法无法预估项目的不确定性价值。然后提出引入实物期权对净现值法进行修正的基本方法，为水运建设项目的投资决策提供了一个崭新的决策思路。     

基于实物期权的港口建设项目投资评价

目前全国各地正在积极进行港口建设,但这种处于行政规划的港口建设在投资方面存在这一系列价值衡量问题,尤其是当港口建设的投资是不可逆时。同时当港口建设投资决策是可以延期时,延期决策是有价值的。文中将实物期权定价理论引入港口建设投资项目评价,为后续港口建设投资的决策提供一种评价方法。

Assessment of investment decision in the dry bulk shipping market based on real options thinking and the shipping cycle perspective

As the dry bulk shipping market seems to have been stuck in a trough period for a long time, investors need to pay more attention to their investment strategies to survive during this period. This study aimed to find a suitable model to assess dry bulk ship investment decisions in the tough and peak periods based on real options theories. Two options, involving an abandonment option and a deferrable option, were used to define investors’ responses to the uncertainty in investment processes such as stopping or selling vessels. The option valuation was solved by using a binomial valuation model, due to data limitations. In accordance with shipping cycle theories, different volatility parameters for the tough and peak periods were calculated using a generalized autoregressive conditional heteroskedasticity (GARCH) model. The application of the real options model to a case study involving secondhand ship trading indicated its viability. According to the results of the case study, the new model has advantages over the traditional net present value (NPV) method in uncertain investment environments. Thus, the results demonstrate that the real options model is a more suitable method for use in the current dry bulk shipping market.     

Maritime investment strategies with a portfolio of real options

The maritime industry operates in a dynamic global environment subject to a great number of variables. In this context, the investment challenge facing shipowners is correctly to value alternate mutually exclusive investment strategies before proceeding with confidence to commit to a project which will add the greatest value to the firm. To survive in the competitive market environment shipping companies must be flexible. Companies that rely solely on traditional discounted cash flow analysis may be underestimating the true value of their investment by not valuing any embedded real options specifically. To avoid misallocation of resources, the true value of these embedded options (strategies) should be recognised and quantified where possible for inclusion in the capital budgeting process. Using real options analysis, (ROA), as a development of the financial pricing advances of the 1970s, flexibility is valued like a financial option using non-arbitrage and added to the present value of the original strategy to derive the present value of the flexible strategy. The more uncertainty (risk) present, the greater will be the value of the real options. Similarly, the larger the shipowner's portfolio of options (strategies) from which to choose, the greater will be the valuation of the project. Real options give the shipowner the flexibility to exchange one risky income stream associated with one strategy for that of another. The analysis shows that if managers have the flexibility of more than one embedded option (in this paper, a European put associated with a replacement investment and an option on the maximum of two operating strategies, trading or chartering out) then the project will have greater value than if the there was no choice or if it was limited to one or the other strategy. Sensitivity analysis extends the analysis to demonstrate that if the volatilities of the risky income streams are highly correlated then the additional value of this flexibility will diminish.     

Shipping and investment incentives: a trilogy Part 3. The effectiveness of investment incentives for shipping—the UK experience 1950-1987

This paper concentrates on the determinants of investment and examines both theoretical and empirical work on the investment function. The major determinants are considered and a case study of the United Kingdom shipping industry in the period 1963-1987 is undertaken. The analysis is unable to find any real link between the value of the investment incentives packages available to the UK shipping industry and the size of the UK fleet during this period. The conclusion follows that while financial factors (e.g. favourable credit arrangements) or individual components (e.g. investment grants) of fiscal packages may influence the decision to invest, the total package has not affected the level of shipping investment in the manner expected.

Investment strategies in market uncertainty

The nature of the global economy is one of dynamic change. Shipping is a service industry with its demand related to changes in international trade levels and patterns. As a consequence shipping is subject to sometimes unpredictable swings in demand so that the operator is required to make strategic planning decisions while navigating through boom or bust environments. While boom economies generate rising freight rates which are welcomed and encourage investment, ship operators may also have to face falling freight demand and declining freight rates that may have significant impact on profitability, often falling to uneconomic levels for extended periods. In such a period of uncertainty and declining profitability management will make operational decisions to reduce costs. However, shipping lines operate in a market environment so any decisions made to rationalize the trade may have significant long-term competitive implications. For example, traditional micro economic theory might suggest that the prudent strategy to adopt would be to close down the operation and reopen when the market conditions improve. In a world of certainty or when costs of taking this action are zero, this would be a valid strategy. However, because of fear of competitors taking up a line's market share if the shipping company exits, even temporarily, this strategy cannot be valued simply in terms of shut-down and start-up costs. A further consideration is the fact that standard capital budgeting techniques, such as Net Present Value (NPV), cannot incorporate the flexibility to respond to new information and strategic responses explicitly into their investment analysis. This paper will demonstrate the use of Real Option Analysis (ROA) to provide guidelines for decisions about closing operations in adverse market conditions.

Port or shipping project appraisal under risk .

Investments in ports and shipping today are subject to uncertainty in demand, costs, prices, and technology requirements. As a result, port and shipping project appraisal must consider the risk of project decisions on outcome. The basic concepts of project appraisal under risk are discussed in this paper, and the effects of uncertainties on measures of project performance such as net present value or internal rate of return are reviewed. Applications of the approach advocated are presented in a follow-up paper.
