A social time preference methodology derived from Feldstein (1965) is applied to calculate social discount rates across 167 countries and across time from 2005-2050 for a country case (Brazil). This attempt seeks to compute comparable figures from a homogeneous dataset and provides a...

Public-private partnerships (PPPs) involve the supply by the private sector of infrastructure and services deriving from infrastructure assets which have traditionally been supplied by the public sector. PPPs are spreading all over the world. It may be quite plausible that such arrangements were...

The appropriate measure of the social discount rate is the social opportunity cost of borrowed funds (a weighted average of the rates of return on displaced investment, postponed consumption, and incremental foreign funding), which ensures that a proposed policy produces a potential Pareto...

This is an annotated appendix that accompanies the paper. In this note, we provide detailed commentary on a numerical example that illustrates the ideas that we discuss in the main paper. The numerical example is in Table18.10, Chapter 8, page 656, of the third edition of Corporate Finance,...

In this note, we extend a numerical example in the textbook by Berk & DeMarzo that matches methods for only when K_TS is equal to K_D. We show that there is a generalized formulation for the return to levered equity K_E that works for any value of K_TS, the appropriate discount rate for the tax...

In this short note, we present a nontechnical retrospection on the unbearable longevity of the classic WACC (Weighted Average Cost of Capital) for the Free Cash Flow (FCF) in perpetuity. Over the past two decades, researchers in finance have increased greatly our understanding of the properties...

There is a fatal logical-methodological fallacy involved in the Kaldor-Hicks principle which analyzes a Pareto improvement into an "efficiency" part and an "equity" part--so that economists can supposedly recommend the efficiency part in their scientific role as economists while leaving the...

The view that intergenerational distributive justice and efficiency should be treated separately is familiar, yet controversial. This article elaborates the often-implicit justifications for separate treatment and provides a more express statement of how and when such treatment is appropriate....
