Herein we develop a psychophysical model of decision making based on the difference between objective clock time and the human brain’s perception of time. In this model the utility function is given by the survival probability, which is shown to be a generalized hyperbolic distribution. The...

Ambition as the desire for personal achievement is an important driver of behavior. Using laboratory experiments, we study the role of social influence on ambition in two distinct domains of achievement, namely performance goals and task complexity. In the first case, participants set themselves...

I study the effect of task difficulty on workers' effort. I find that task difficulty has an inverse-U effect on effort and that this effect is quantitatively large, especially when compared to the effect of conditional monetary rewards. Difficulty acts as a mediator of monetary rewards:...
