Greater emphasis on how psychological biases influence both the behavior of investors and asset prices has led to a strong debate among proponents of behavioral finance and neoclassical finance. This has created the need to study how psychology affects financial decisions in households, markets and organizations. This study conducts a pooled ordinary least squares (OLS) model using the fixed effects estimator to investigate the linkage between investor sentiment and stock prices for 35 firms belonging to three different industries over a time period of 56 years, from 1950 to 2005. The findings suggest that investor sentiment does not significantly affect the stock prices in this sample. 2011-02-11 10:39:05 Paudel, Jayash og Laux, Judy http://adr.coalliance.org/coccc/fez/view/coccc:3306 Using representative samples from populations of 19 sub-Sahara African countries, this paper investigates the effects of different levels of HIV/AIDS knowledge on sexual behavior of males with country specific effects and controls for socioeconomic characteristics and location of residence. The main findings are that HIV/AIDS knowledge increases the likelihood of using condoms with and without commercial sex workers, has no significant effect on the likelihood of paying for sex, and increases both the likelihood of having pre and extra marital sex. These results indicate that increased HIV knowledge on average does not lead to safer sexual behavior of males in sub-Saharan Africa at the macro level. 2011-02-11 09:36:39 Agarwal, Smriti og De Araujo, Pedro og Paudel, Jayash
