A typical approach for valuing finite cash flows is to assume that leverage is constant (usually as target leverage) and the cost of equity, Ke and the Weighted Average Cost of Capital, WACC are also assumed to be constant. For cash flows in perpetuity, and with the cost of debt, Kd as the...

The choice of an appropriate discount rate is of major importance in cost benefit analysis both, at the private and at the social levels. The theories that rationalize the NPV criterion also identify the appropriate rate. However, the question remains as to what should be done when the...

Currently, we are in the process of experimenting a diversification and refinement of the consumerâ€(tm)s expectations, as well as a growing demand for innovative, quality products and customized services, exacerbated by rapid technological change affecting both them and the producers. It is...

The judicious selection of investment projects, at the micro and macro level, with recognition of resource constraints and complementary involvement of the private sector, will lead to sustained economic growth, equitable development, poverty reduction and private sector growth. Cost-Benefit...

In a growing economy, the discount rate to evaluate a long-term investment is the minimum rate of expected return that compensates for the increased intergenerational inequalities. Because the growth rate is uncertain, there is a precautionary argument in favor of lowering the discount rate. If...

We ask whether the US government should replace its current discounting practices with a declining discount rate schedule, as the United Kingdom and France have done, or continue to discount the future at a constant exponential rate. We present the theoretical basis for a declining discount rate...

Conventional benefit–cost analysis incorporates the normally reasonable assumption that the policy or project under examination is marginal. Among the assumptions this entails is that the policy or project is small, so the underlying growth rate of the economy does not change. However, this...

Standard cost-benefit analysis (CBA) does not take into account induced demand due to relocation triggered by infrastructure investments. Using an integrated transport and land-use model calibrated for the Stockholm region, we explore whether this has any significant impact on the CBA outcome,...

We modify a method recently suggested by Weitzman (2012, 2013) for determining a risk-adjusted social discount rate (SDR) term structure consistent with both the (augmented) Ramsey rule and the consumption-based CAPM. Using this approach we estimate SDR for transportation infrastructure...

The economics of climate change and the various measures that should be implemented to reduce future damages are highly tied to the use of cost-benefit analysis. Traditional approaches ignore the fact that environmental amenities do not experience the same growth rate as do most of the sectors...
