- 1 - Discounting and risk adjusting non - marginal investment projects
نویسنده
چکیده
Standard cost-benefit analyses and asset pricing theories are based on the assumption that investment projects have marginal impacts on the consumption flows of stakeholders, so that social values and prices are not affected. This may not be true for large projects, such as those related to climate change or to the implementation of infrastructure projects in developing countries. In this paper, we explore qualitatively and quantitatively the error that is made when using the standard evaluation methods for non marginal projects. In particular, we discuss the importance of adapting the discount rate and the risk premium to the size of the investment projects under consideration.

The debate on discounting: Reconciling positivists and ethicists
Using a simple arbitrage argument, positivists claim that the interest rate provides the right basis to fix the discount rate to evaluate green investment projects. The real interest rate observed in the U.S. during the XXth century has been around 1% and 2%. On the contrary, ethicists estimate the discount rate by the marginal rate of substitution between current and future consumption. From c...
متن کاملAsset allocation, sustainable withdrawal, longevity risk and non-exponential discounting
The present paper studies an optimal withdrawal and investment problem for a retiree who is interested in sustaining her retirement consumption above a prespecified minimum consumption level. Apparently, the withdrawal and investment policy depends substantially on the retiree’s health condition and her time preferences (subjective discount factor). We assume that the health of the retiree can ...
متن کاملDiscounting the distant future—Data on Australian discount rates estimated by a stochastic interest rate model
Data on certainty equivalent discount factors and discount rates for stochastic interest rates in Australia are provided in this paper. The data has been used for the analysis of investments into climate adaptation projects in ׳It׳s not now or never: Implications of investment timing and risk aversion on climate adaptation to extreme events׳ (Truong and Trück, 2016) [3] and can be used for othe...
متن کاملTime (in)consistency and real options: Much ado about nothing?
If decision makers have exclusive rights to particular investment projects, they frequently have the opportunity to delay these investments. This paper analyzes the effect of quasi-hyperbolic discounting, i.e. timeinconsistent preferences on the exercise timing of such options to defer an investment. It complements earlier work on this issue covering risk aversion and capital market interaction...

Empirical studies show that there is stronger dependency between large losses than large profit in financial market, which undermine the performance of using symmetric distribution for modeling these asymmetric. That is why the assuming normal joint distribution of returns is not suitable because of considering the linier dependence, and can be lead to inappropriate estimate of VaR. Copula theo...
