Gender Differences in Hope and Its Relevance to Depression Symptoms among Norwegian Adolescents

Introduction: Several studies indicate that the number of individuals experiencing depression symptoms is growing. There is a prevailing consensus in the literature that while depression is represented among both genders, it is consistently reported that females are more exposed to depression compared to males both in frequency and severity. Studies suggest that as many as 15 - 20 percent of adolescents in Norway exhibit depression or depression like symptoms. Furthermore, several studies indicate that the number of individuals experiencing depression symptoms is growing. There is a prevailing consensus in the literature that while depression is represented among both genders, it is consistently reported that females are more exposed to depression compared to males both in frequency and severity. Methods: All data utilized in this study were extracted from the Norwegian Ungdata survey conducted in 2014 among adolescents in Norway. The sample consists of 46,374 observations. Conclusions: The finding of significant differences in prevalence of self-diagnosed depression symptoms among Norwegian adolescents, showed females are more exposed. Furthermore, as hypothesized, there is a strong and significant relation between hope and depression, where hope is proxied through expectations regarding the individuals’ future education, happiness and wealth. Based on these findings, we apply hope as an instrument for addressing depression symptoms. Results from this analysis indicate that males are significantly less optimistic for the future.

The cross section of Chinese commodity futures return

This paper investigates the cross-section of expected commodity futures returns in China using a large panel of 13 individual factors.We find that 6 out of 13 individual factors produce positive and significant returns.To aggregate the information among these factors,we apply not only the traditional Fama-Mac Beth regression(FM),but also a set of alternative methods,including the forecast combination method(FC),principal component analysis(PCA),principle component regression(PCR)and partial least squares(PLS).It turns out that PLS outperform other methods in forecasting the cross-section of Chinese expected futures returns.The equally weighted combination of 5 methods produces an even higher annualized return and lower standard deviation compared to each single method.The investigation of factor importance reveals that the skewness(SKEW)factor is more important than other factors in predicting expected futures returns in Chinese markets.
