We provide an extensive set of alternative models for the estimation of the real cost of equity in a sample of utilities firms in Brazil with monthly data from March 2006 to June 2011. The traditional CAPM is rejected, together with the Fama-French factors, due to a poor fit. Additional factors...

We numerically solve systems of Black–Scholes formulas for implied volatility and implied risk-free rate of return. After using a seemingly unrelated regressions (SUR) model to obtain point estimates for implied volatility and implied risk-free rate, the options are re-priced using these...

We study the effects of two measures of information dissemination on the determination of systemic risk. One measure is print-media consumer sentiment based while the other is volatility based. We find evidence that while the volatility measure (VIX) of future expectations has a more significant...

This paper implements an algorithm that can be used to solve systems of Black-Scholes equations for implied volatility and implied risk-free rate of return. After using a seemingly unrelated regressions (SUR) model to obtain point estimates for implied volatility and implied risk-free rate, the...

This paper analyzes the role of government intertemporal budget policies in a growing open economy including nominal assets in the presence of an upward sloping supply of debt. This introduces transitional dynamics that influence the effects of government policy instruments on economic growth...

We analyze a sample of 64 oil and gas companies of the nonrenewable energy sector from 26 countries using daily observations on return on stock from July 15, 2003 to August 14, 2012. A panel model with fixed effects and Tarch effects shows significant prices for specific risk factors including...

We analyze a sample of 64 oil and gas companies of the nonrenewable energy sector from 24 countries using daily observations on return on stock from July 15, 2003 to August 14, 2012.

We examine empirical evidence of the behavior of stocks and bonds from BRIC nations using daily data from January 2003 to July 2010. We present unconditional and conditional emprical results depending upon a simple measure of U.S. financial stress. In the long term, BRIC bonds markets deviate...
