The main goal of this study was to analyze the psychometric properties of the Perception of Parents Scale (POPS) developed by Robbins (1994), with a sample of middle-adolescents with ages between 14 and 18 years. The confirmatory factor analysis was conducted to examine the reliability and validity of a three-dimension model of adolescents’ perception of mother and father based on perspective o...

Scholars and investors have been interested in factor models for a long time. This paper builds using the monthly data of A-share market. We construct seven-factor model by adding Hurst exponent momentum to Fama–French five-factor find that there is 7% improvement average R–squared. Then, we compare five machine learning algorithms with ordinary least squares (OLS) one representative stock all ...

This paper offers an alternative method for estimating expected returns. The proposed reward beta approach performs well empirically and is based on asset pricing theory. The empirical section compares this approach with the CAPM and the Fama-French three-factor model. In out-of-sample testing, both the CAPM and the three-factor model are rejected. In contrast, the reward beta approach easily p...

This study provides new estimates of systematic risk and the cost of equity capital for the pharmaceutical, biotechnology, and medical device sectors using data for firms with publicly-traded stock on U.S. exchanges during 2001-2005 and 2006-2008. Two frameworks are employed for estimating firms’ risk and the cost of equity capital: (1) the capital asset pricing model, and (2) the Fama-French t...

This paper provides an alternate method of evaluating portfolio performance of stock pricing models. We apply Pitman Closeness Criterion to compare the accuracy of three popular pricing models. This comparison is used to assess which, if any, model outperforms the others. In assessing model performance over a long period of time, we find that the Fama-French three-factor model and the Carhart f...
