<p>In calculating the cost of capital for regulated businesses, the New Zealand Commerce Commission uses the Capital Asset Pricing Model to estimate the cost of the equity component of capital, a procedure that involves assuming particular values for unobservable key parameters. This thesis proposes, instead, to estimate these parameters from market data. The principal result is that estimates of these parameters differ significantly from the values assumed by the Commerce Commission. Applying these estimates to two recent cases involving the electricity line and gas pipeline businesses, the estimated costs of capital for the entities involved are 3.5% to 5.5% more than those obtained by the Commission, but the associated confidence intervals are wider. One implication of these findings is that the Commissions approach systematically understates the uncertainty surrounding cost of capital estimates.</p>

<p>This paper applies the Ibbotson and Sinquefield (1976) method and the Lally (2002) method to New Zealand data over the period 1960-2005 in order to estimate the market risk premium (MRP) in two versions of the capital asset pricing model (CAPM). With respect to the standard CAPM, the resulting Ibbotson estimate of the MRP for New Zealand was 6.11%. The resulting Lally estimate of the MRP ranged from 5.52% (in 1970) to 18.40% (in 1990), with an average of 7.95%, and was 6.40% for 2005. With respect to the simplified Brennan-Lally CAPM, the resulting Ibbotson estimate of the MRP for New Zealand was 8.49%. The resulting Lally estimate of the MRP ranged from 7.91% (in 1970) to 20.79% (in 1990), with an average of 10.33%, and was 8.78% for 2005. The Lally and the Ibbotson estimates of the MRP are similar in general. However, when market leverage is unusually high or low, they diverge significantly. In future, practitioners may need to choose between the estimates from the two methods when market leverage goes beyond the normal level.</p>

This study discusses financial policies related to costs of capital and costs of debt (capital structure) in the concept of Islamic finance. For a long time capital structure theory has evolved and is used as a reference for evaluating investment decisions for investors and companies that provide a role for managers in making decisions related to the use of company capital so as to improve company performance and value. The current understanding of the cost of equity only refers to the rate of return that is the investor's right to invest in the company. While the cost of debt is understood as the part that must be received from an investment so that the minimum level of return of creditors is met. The underlying theory is, such as the Leverage model; Miller-Modigliani (MM) model; Capital Asset Pricing Model (CAPM); Arbitrage Price Theory (APT); and Gordon's model which has so far been used in financial theories relating to capital structure problems. The concept of capital structure in Islamic finance gives specific emphasis on the use of capital. The concept of self-regulated capital must be in accordance with Islamic law. This means that any use of capital or debt must have a clear purpose in accordance with Islamic principles with the aim of maximizing the problem so that the creation of falah. In the concept of Islamic capital, it is permissible to take a share of profits on capital, but the amount cannot be determined based on a percentage of capital. The profit is an incentive for capital used in business projects, the calculation of which is done after the business process is completed and other obligations have been fulfilled. Keywords: Costs of Capital, Costs of Debt, Capital Structure, Islamic Finance   Abstrak Penelitian ini membahas tentang kebijakan keuangan yang berkaitan dengan biaya modal dan biaya hutang (struktur modal) dalam konsep keuangan Islam. Sejak lama teori struktur modal telah berkembang dan dijadikan sebagai rujukan penilaian keputusan investasi bagi investor maupun perusahaan yang memberikan peran kepada manajer dalam mengambil keputusan terkait penggunaan modal perusahaan sehingga dapat meningkatkan kinerja dan nilai perusahaan. Pemahaman selama ini mengenai biaya ekuitas hanya mengacu pada tingkat pengembalian yang merupakan hak investor atas investasinya di perusahaan. Sedangkan biaya hutang dipahami sebagai bagian yang harus diterima dari suatu investasi agar tingkat hasil minimum para kreditor terpenuhi. Teori yang melandasi tersebut seperti, model Leverage; model Miller-Modigliani (MM); Capital Asset Pricing Model (CAPM); Arbitrage Price Theory (APT); dan model Gordon yang selama ini digunakan pada teori-teori keuangan yang berkaitan dengan masalah struktur modal. Konsep struktur modal dalam keuangan Islam memberikan penekanan secara spesifik dalam penggunaan modal.Konsep modal sendiri diatur harus sesuai dengan hukum Islam. Artinya setiap penggunaan modal atau hutang harus memiliki tujuan yang jelas sesuai dengan prinsip syariah dengan tujuan untuk memaksimumkan maslahah sehingga terciptanya falah. Dalam konsep modal Islam memperbolehkan pengambilan bagian keuntungan atas modal namun besarannya tidak boleh ditetapkan berdasarkan persentase dari modal. Laba tersebut merupakan insentif atas modal yang digunakan dalam proyek bisnis yang perhitungannya dilakukan sesudah proses bisnis selesai dan kewajiban-kewajiban lain telah terpenuhi. Kata kunci: Biaya Modal, Biaya Hutang, Struktur Modal, Keuangan Islam

Using data from 2010 to 2019, for the first time, the Capital Asset Pricing Model (CAPM) and the Three-factor Model (TFM) are compared in different contexts of the Vietnamese economy (recession and recovery). This paper employs four tests including the t-test, determination coefficient R2, Chow-test and GRS-test to examine the performance of the two models. Results show the superiority of the TFM over the CAPM in both contexts of the economy, consistent with Fama and French’s studies. This promises that the TFM can be used to replace the CAPM in capturing the cost of equity. Another finding is that the two models tend to perform better in recession than recovery. This study contributes to the literature about asset-pricing models and their performances in different economic contexts. Moreover, the findings also offer insights into the use of the CAPM and TFM in developing countries in general and Vietnam, in particular.

Cuando se evalúan proyectos de inversión a nivel de perfil, los flujos de caja se descuentan a una tasa de descuento igual a la tasa de interés activa vigente en el mercado; esto es así porque a nivel de perfil, la exigencia y precisión del estudio es relativa; sin embargo, en la etapa de evaluación del proyecto la tasa de descuento se torna en un dato relevante y esta debe representar el coste del capital del proyecto en particular, es decir, para determinar la tasa de descuento para un proyecto en particular, luego de elaborado el flujo de fondos netos, se debe proceder al cálculo del coste del capital utilizando los métodos o modelos más importantes: el capital asset pricing model (modelo de valoración de activos financieros), y el weighted average cost of capital (modelo del costo del capital promedio ponderado). Luego se podrá obtener el nivel de rentabilidad esperado utilizando los distintos criterios existentes.

O artigo tem como objetivo demonstrar que o Custo de Capital regulatório fixado pela Agência Nacional de Energia Elétrica – ANEEL para as empresas Transmissoras de Energia Elétrica no Brasil está aquém dos reais custos de oportunidade de capital próprio e de recursos oriundos de capital de terceiros necessários aos investimentos empregados no setor. Dessa forma, realizou-se uma análise do custo de capital atual da Companhia Estadual de Geração e Transmissão de Energia Elétrica – CEEE-GT, utilizando os mesmos parâmetros e metodologias de cálculo empregadas pelo Órgão Regulador, que consiste na combinação dos modelos CAPM (Capital Asset Pricing Model) e WACC (Weighted Average Cost of Capital).
