Abstract: | Desirability bias is the tendency to overpredict desirable outcomes and underpredict unwanted outcomes. Previous research suggests that this bias is quite pervasive among non-experts but there is very scant evidence of its intensity among experts. For at least twenty years, financial academics and, to a lesser extent, practicing investment managers have claimed that the finacial markets are among the most efficient and bias free in existence. Therefore, this paper examines the degree of desirability bias among expert and practicing US and Taiwanese investment managers. |
