Journal of Financial and Quantitative Analysis (Impact Factor: 1.77). 01/2006; 41(04):939-962. DOI: 10.1017/S0022109000002702

ABSTRACT This paper investigates whether some individuals are prone to behavioral biases in their 401(k) investments. Using demographic data and allocation information for over 73,000 employees, I examine two allocation biases and a participation bias. The findings suggest that higher salaried employees tend to make significantly better choices. Participants who earn $100, 000 hold 12. 7% less in company stock, are 3% less likely to follow the framing 1/n heuristic, and are 37.7% more likely to participate than those earning $46, 000. Women make better choices in two of the three cases and I find evidence of mental accounting.

    ABSTRACT: This study examines why banks offer multiple and similar deposit services with different interest rates. This examination considers how bank deposit interest rate setting is influenced by customers assumed to have different propensities to switch deposit accounts according to the degree they discount the costs and benefits of decisions. It is reported banks can enhance profits by introducing duplicate new deposit products with competitive interest rates for new customers and lowering interest rates on existing deposit services. Model predictions that the number of deposit accounts and level of interest rates varies by institutional type, higher levels of deposit balances are associated with less uncompetitive accounts and the level of interest declines with the age of the deposit account are all not rejected.

    ABSTRACT: Gender differences in personal saving behaviors among single person households were investigated using the 2007 Survey of Consumer Finances (SCF). Determinants of short-term and regular saving behavior were found to differ by gender. Women (n = 702) were less likely to save in the short term if they were in poor health, while poor health did not significantly affect the short term saving of men. Having low risk tolerance negatively affected the likelihood of women saving in the short term and saving regularly, while each year of education made men (n = 469) more likely to save in the short-term and to save regularly. Understanding the saving behaviors of men and women can help improve the efforts of financial professionals and educators. A number of studies have shown that the economic well-being and financial behaviors of men and women differ significantly. Women hold lower levels of wealth and have significantly lower earnings than men. In addition, women spend as many as five more years than men in retirement as a result of having longer life expectancies (Gottschalck, 2008; U.S. Bureau of the Census, 2007). Researchers and financial practitioners have reported that women invest their financial resources more conservatively and are, in general, more risk averse than men (Bajtelsmit,. Researchers have also found that women have lower rates of participation in retirement plans as compared with men (Sung, 1997) and are more likely to be living in poverty during retirement (Pearce, 1989). The combination of lower earnings, lower savings, longer life spans, and higher risk aversion when investing presents women, financial educators, and policymakers with a significant challenge (Embrey & Fox, 1997). Although much is known about differences in income, risk aversion, investment behaviors, and level of wealth, little is known about how the factors related to general saving behaviors may differ between men and women. Schmidt and Sevak (2006) reported that across many different countries, large differences in economic well-being
