An emulation fund is designed to reduce trading activity, thereby lowering costs, for a multi-manager fund. It does this by delaying, and potentially combining, trading decisions from each employed fund manager to eliminate offsetting trades (e.g. one manager may buy a stock for her fund while...

Two studies were conducted in which student participants gave overall hedonic evaluations of past relationships or their high school days, and, additionally, gave similar evaluations of the best, most memorable, worst, initial, and final moments from them. They also evaluated a typical moment...

Five experiments investigated whether including self-assessments in applications for a promotion might affect their evaluation, and how this effect was influenced by measures taken to reduce or eliminate it. Self-assessments influenced judgment when the applications were judged by novices and...
