An adequate rate of return on capital yielded by the regulated firms is a central issue related to the new cost-based approach adopted by the Brazilian Telecommunication Regulatory Agency (Anatel). In this context, careful attention must be given to the Weighted Average Cost of Capital (WACC)...

In this paper we discuss the several aspects involved in the determination of the cost of capital of the telecommunications industry in Brazil. The cost of capital determination for regulated industries is extremely important, both to regulators and firms, since through the pertinent rate of...

The current methodology adopted by the Aneel to estimate the rate of return (cost of capital) applied in the periodic tariff revision is improved via some modifications in the following parameters: country risk, exchange rate risk and regulatory risk. We recommend the global CAPM methodology...

Tim Xiao: This paper argues that the reduced-form jump diffusion model may not be appropriate for credit risk modeling. To correctly value hybrid defaultable financial instruments, e.g., convertible bonds, we present a new framework that relies on the probability distribution of a default jump...

This paper attempts to assess the economic significance and implications of collateralization in different financial markets, which is essentially a matter of theoretical justification and empirical verification. We present a comprehensive theoretical framework that allows for collateralization...

This paper presents a new framework for credit value adjustment (CVA) that is a relatively new area of financial derivative modeling and trading. In contrast to previous studies, the model relies on the probability distribution of a default time/jump rather than the default time itself, as the...
