论项目投资评价中的时间风险值效应及其选择

基于现行现金流折现的项目投资评价的有效性取决于对项目现金流量预测的正确性,而项目现金流量具有预测发生的时间越遥远,现金流量不确定性的程度越大但又趋于相对稳定的特征.从这一特征出发,本文引入时间风险值进行折现调整这种系统可循的方法来解决在投资评价时难以预计的项目现金流量未来的不确定性问题,从而使不确定性条件下的项目投资评价更具有客观性.

Determinants of patent value: Insights from a simulation analysis

This paper contributes to understanding the determinants of patent value. By drawing on a real options approach, we develop a theoretical model of patent value, which explicitly considers the uncertainty about future value. On this basis, we rely on Monte Carlo simulations with data from a case study in a large chemical firm to estimate patent value according to our model. In the simulation analyses, we compare an R&D project with patent protection and the same project without patent protection. The difference of the values of the two projects is the surplus in profit that may be expected from having a patent covering the project. This surplus is regarded as the value that is directly attributable to the patent. The results of the simulation analyses indicate that the development costs and expected net cash flows of a patent-protected project are higher than of an unpatented project. The higher net cash flows outgrow the increased development costs, and patent value is positive. However, this value is smaller than the overall project value of the patent-protected R&D project.     

On the Separability of Real and Financial Decisions

The financial manager faces two basic problems: first, the firm’s investment or capital budgeting decision, and second, the financing decision. Capital investment and financing decisions are typically analyzed independently. Capital budgeting criteria proceeds under the simplest possible assumption about financing, namely all-equity financing. The only link between investment and financing decisions is the cost of capital. The basic idea behind Modigliani and Miller’s famous proposition I is that in perfect markets, changes in capital structure do not affect value. As long as the total cash flow generated by the firm’s assets is unchanged by capital structure, value is independent of capital structure. This paper is the first attempt to prove that leverage affects the mathematical structures of the cash flow of financing, and that different mathematical structures of financing cash flows may change the total cash flows generated by the firm or the project, thus altering the value of the firm even in perfect markets. The purpose of this paper is to explore the validity of the separation rule through net present value (NPV) and internal rate of return (IRR) rules, as representatives of academic and business practice, and compare their results with simulations that will include the financial decision of the firm. A singular experiment proving that we can change the IRR or NPV of an investment modifying the financial structure cannot be used to affirm a universal statement, but it can be used to show that a theory is wrong.     

Investor sentiment and the prediction of stock returns: a quantile regression approach

We employ quantile regression to provide a detailed picture of the stock return forecasting ability of investor sentiment. We find that investor sentiment predicts aggregate stock returns at lower quantiles. However, the forecasting power is lost at upper quantiles. The results are robust after controlling for a comprehensive set of macroeconomic and financial predictors and for characteristic portfolios. We also show that investor sentiment consists mainly of cash flow news and contains little information about discount rate news. The ability to forecast cash flows increases gradually from the lower quantiles to upper quantiles. Our results do not support that the ability of investor sentiment to predict stock returns comes from a rational forecast of future cash flows.     

A Japanese NAMEA

The Japanese NAMEA presented here serves several purposes which include the provision of: (1) a comprehensive and consistent picture of the interrelationship between the economy and the natural environment; (2) a basis for applications of cost-benefit analysis; and (3) the necessary information for policy planning. The NAMEA gives environmental pressures not only from domestic pollutant emissions, but also from transboundary flows from the rest of East Asia. Furthermore, attention is paid to pollutant emissions in East Asia in relation to future growth potential. Global warming effects of the six gases listed in the Kyoto Protocol are discussed, based on newly available physical data. Also presented are several other indicators for Japan, some of which are presented for the first time.     

Owning capital or being shareholders: An equivalence result with incomplete markets

Many recent papers in macroeconomics have studied the implications of models with household heterogeneity and incomplete financial markets under the assumption that households own the stock of physical capital and undertake the intertemporal investment decisions. In these models, production exhibits constant returns to scale, households maximize expected discounted utility, and firms rent capital and labor from households to maximize period by period profits. This paper considers the case in which infinitely lived firms, rather than households, make the intertemporal investment decisions. Under this assumption, it shows that there exists an objective function for firms that results in the same equilibrium allocation as in the standard setting with one period lived firms. The objective requires that firms maximize their asset value, which is defined as the discounted value of future cash flows using present value processes that do not allow for arbitrage opportunities.

The derivation of the NPV variance of a risky capital investment project with first-order autoregressive cash flows and autoregressive conditional heteroscedastic variances

In this article, the authors develop a closed-form solution for assessing the capital investment project NPV variance when cash flows obey a first-order autoregressive process. A distinction is established between static and dynamic solutions as the authors focus on the case involving partial positive dependence between cash flows. Under a Markovian process, the NPV solution is stationary in mean but not strictly in variance. Constraining the process to become fully stationary will overestimate the NPV variance. Finally, the authors show that the Markovian NPV variance closed-form solution is robust to the introduction of autoregressive conditional heteroscedastic variances complying with a GARCH(1,1) process; it will, however, have its value increased and consequently the riskiness of the capital investment project.     

The Influence of Financial Factors on Corporate Investment

Abstract
Recent theoretical developments have shown that cash flows and the structure of a firm's balance sheet may have an important influence on investment. Establishing a link between cash flows, leverage and investment provides insights into the way that monetary policy and cyclical factors more generally influence the corporate sector. If cash flows are an important determinant of investment then changes in monetary policy (by changing interest rates) will influence investment through a cash flow effect as well as through altering the rate at which the returns to investment are discounted. If this is the case, the higher leverage of the corporate sector implies, other things being equal, that monetary policy may have a larger impact on investment than in the past .
In this article we use panel-data analysis to examine the impact of financial factors on investment decisions of firms in the Australian corporate sector. We find strong support for the influence of financial factors on investment decisions. Leverage, internally generated cash flows, and the stock of cash and liquid financial assets are all important influences on investment behaviour, particularly for smaller firms, highly leveraged firms, and firms with high retention ratios .     

Patents and R&D as Real Options

This article develops and implements a simulation approach to value patents and patent‐protected R&D projects based on the Real Options approach. It takes into account uncertainty in the cost‐to‐completion of the project, uncertainty in the cash flows to be generated from the project, and the possibility of catastrophic events that could put an end to the effort before it is completed. It also allows for the possibility of abandoning the project when costs turn out to be larger than expected or when estimated cash flows turn out to be smaller than anticipated. This abandonment option represents a very substantial part of the project's value when the project is marginal or/and when uncertainty is large. The model presented can be used to evaluate the effects of regulation on the cost of innovation and the amount on innovative output. The main focus of the article is the pharmaceutical industry. The framework, however, applies just as well to other research‐intensive industries such as software or hardware development.

Intergenerational transfers and the social discount rate

This paper investigates the relationship between intergenerational asset transfers and the choice of the discount rate for use in cost-benefit analysis in a model of a competitive overlapping generations economy constrained by a socially managed exhaustible resource. Provided that there are no distortions in capital markets and that all agents hold perfect foresight, cost-benefit techniques will result in a Pareto efficient resource allocation if the discount rate is set equal to the market rate of interest. But since the path of the interest rate depends on the level of intergenerational transfers, cost-benefit techniques do not ensure a socially desirable distribution of welfare between generations; a social optimum will result only if intergenerational transfers are properly chosen and enforced. Decentralized private altruism may result in intergenerational transfers that both present and future individuals would agree are too small if members of the present generation attach positive weight to the general welfare of future generations, not simply their personal descendants. In a world where intergenerational transfers are non-optimal, second-best policy-making may imply a constrained optimum that is inefficient. Together, these findings suggest that cost-benefit analysis is at best a partial criterion to policy formulation that should be used only in conjunction with ethical principles that define the proper distribution of welfare between present and future generations.     

Investing in mutual funds: the determinants of implied and actual net cash flows

Estimating the fund investors’ demand plays an important role in the mutual fund management. In this line, mutual fund demand can be measured as the total net cash flows experienced by the fund during a period. Due to a lack of the data for inflows and outflows in some countries and databases, many authors estimate the net cash flows using fund size and return information. This rough measure, although being a good approximation, implicitly assumes an error in its calculation. For a sample of 2985 US open-end funds, we find evidence that estimating this implied fund flows, the error generated is higher for smaller funds, funds with higher returns, and for those experiencing higher levels of inflows or outflows. This lack of precision leads to a distortion in the estimation of the effect of some determinants on the mutual fund demand, especially when longer periods are considered when constructing the net cash flows.     

Cash flow vs. collateral‐based credit

We study factors affecting micro, small and medium‐sized enterprises (MSMEs) receiving loans and the effect of these loans on MSMEs performance. We study two types of loans – a new type based on cash flows and a traditional‐style loan based on collateral. We use unique surveys of MSMEs from Bulgaria, Georgia, Russia and Ukraine. We find that MSMEs receiving a cash flow or collateral loan in the past are more likely to receive the same type of loan (and larger sized) in the future and that cash flow loans may be the preferred form of credit. Both types of loans are related positively to most performance indicators, enabling the MSMEs for instance to be more profitable and expand production. The cash flow loans also appear to be particularly attractive credit delivery schemes for micro and small enterprises. Finally, the effects of the smallest loans are often negative, suggesting that the minimum loan size is an important policy issue.     

Economic impact analysis of industrial projects: An approach

A method of calculating economic impact of industrial project proposals is described. The method identifies the benefits and costs of a project to the enterprise and to government, as well as its impact on the economy as a whole, with or without government assistance or intervention in any form. Entrepreneurial and social potentials or driving forces are identified, together with potentials common to both. The analytical method, called economic fertility analysis, employs a large input-output model of the economy to generate a series of impact elements, including increased economic activity, new government revenues, trade balance effects, new capital generation, personal savings, consumer expenditures, and employment. These elements are used to calculate simple income and employment multipliers, forward and backward linkages, and cash flows through the economy resulting from the project. A method of comparing different types of investments or interventions in the economy thus becomes available.     

Lifetime vs Annual Tax-Transfer Incidence: How Much Less Progressive?

Annual fiscal incidence studies have found that income taxes and cash transfers are highly progressive and that their net effect is to redistribute income from rich to poor. Yet many argue Jhat such studies overstate the redistribution achieved by governments and that lifetime analysis is needed New results suggest that both income taxes and cash transfers are progressive on a lifetime basis, although they are much less progressive than annual studies suggest. The Australian tax-transfer system thus generates some lifetime redistribution from rich to poor, while also enforcing intra-personal redistribution across the life cycle of individuals.     

Cash Flow Is King? Cognitive Errors by Investors

When investors fixate on current earnings, they commit a cognitive error and fail to fully value the information contained in accruals and cash flows. Extending the accrual anomaly documented by Sloan [1996], we identify significant excess returns from a cash flow-based trading strategy. The market consistently underestimates the transitory nature of accruals and the long-term persistence of cash flows. We find that the accrual anomaly derives from the poor performance of high accrual firms, which are more likely to manage earnings. Combining the accrual and cash flow information also reveals that investors misvalue the quality of earnings. Contrary to Fama [1998], these anomalies are robust to the three-factor model with equally or value-weighted portfolio returns.     

Comparing approaches to valuing sectoral net investments

In the literature of comprehensive national accounts, national net investments are used to indicate dynamic welfare improvement in an economy. A well-known approach associates national net investments with the shadow value of change in stock of capital assets in an economy. Following this capital stock approach, sectoral net investments can be defined as the shadow value of change in stock of capital assets owned by a sector in an economy. An alternative approach is based on future commodity flows to a sector. This commodity flow approach associates sectoral net investments with the present value of changes in future commodity flows to a sector. In the present paper, I compare these two approaches and prove that they coincide with each other only if the future commodity flows to the sector can be attributed to current stock of capital assets in the sector alone. In empirical studies, commodity flow approach can be a better alternative if the purpose is to estimate the contributions to national net investments of a recipient of future cash flows.     

Altruism in cost-benefit analysis

It has recently been argued that altruistic motives for paying for a public sector project should be ignored in a cost-benefit analysis. The reason is that including altruism would mean a kind of double counting of the project's benefits. This paper takes a look at these arguments, and derives cost-benefit rules which cover different kinds of altruism. The paper also provides some recommendations for the treatment of altruism in studies using the contingent valuation method.     

Implementing QALYs in the Analysis of Air Pollution Regulations

In recent years, there has been growing interest in cost-effectiveness analysis for environmental regulations using quality-adjusted life years as the measure of effectiveness. This paper explores the implications of the QALY approach for measuring the impacts of air pollution regulations, with an example using the U.S. Environmental Protection Agency’s Heavy Duty Engine/Diesel Fuel regulations. The paper also examines the issues surrounding the potential use of QALY measures in cost-benefit analysis for air pollution regulations. Key findings are that, compared with a cost-benefit approach, the QALY framework gives more weight to reductions in incidence of chronic disease relative to reductions in premature mortality risk, especially when the mortality risk reductions occur in older populations. In addition, use of monetized QALYs in cost-benefit analysis is not recommended, due to fundamental differences in the theoretical grounding of the different measures. However, application of monetized QALYs based on age-specific willingness to pay (WTP) for mortality risk reductions gives very similar results to typical cost-benefit analysis for mortality risk reductions, as opposed to using values for QALYs based on non-age specific WTP. The paper concludes that in cases where mortality provide the majority of a regulation’s impacts, QALY based cost-effectiveness analysis and WTP based cost-benefit analysis may not differ in their conclusions. However, in cases where morbidity or non-health outcomes are significant, cost-effectiveness and cost-benefit analysis may result in different evaulations of the efficiency of the regulation.
