Minimum-maximum effort intervals are applied in the planning of software development projects in order to, among other things, determine the contingency buffer. Several studies suggest that judgment-based minimummaximum intervals are based on a systematic over-confidence in the accuracy of the effort estimates. In this paper, we investigate whether the possession by estimators of information ab...

The ability to perform different tasks by a serial manipulator mounted on legged robots, increases the capabilities of the robot. The position/force control problem of such a robot in the stance phase with point contacts on the ground is investigated here. A target plane with known stiffness is specified in the workspace. Active joints of the legs and serial manipulator are used to exert the de...

This paper investigates the possibility that the imposition of a minimum wage increases employment in the affected sector, measured in terms of hours of work, and lowers product prices. Unlike related prior theoretical research, I consider a neoclassical perfect information economy. Both labor and product markets are assumed to be perfectly competitive. Workers choose the number of hours of wor...

This paper reports data for coordination game experiments with random matching. The experimental design is based on changes in an effort-cost parameter, which do not alter the set of Nash equilibria, nor do they alter the predictions of dynamic adjustment theories based on imitation or best responses to others’ decisions. As would be expected, however, increases in effort cost result in reduced...

We consider the effect of an increase in the minimum feasible payment (driven by a minimum wage, limited liability, social norms or a legal restriction that pay cannot be negative) in markets with performance pay. We build a model in which a principal can adjust both the incentives of agents and the number of agents it employs. While a principal with a fixed number of agents will typically redu...
