In a seminal paper, B. R. Holmstro m and P. R. Milgrom (1987, Econometrica 55, 303 328) examine a principal-agent model in which the agent continuously controls the drift rate of a Brownian motion. Given a stationary environment, they show that the optimal sharing rule is a linear function of aggregated output. This paper considers a variant of the Brownian model in which control revisions take...

In this paper, a method to automatically extract the main information from a long-term electrocardiographic signal is presented. This method is based on techniques of pattern recognition applied to speech processing, like dynamic time warping, and trace segmentation. In order to fulfill this objective, a clustering process is applied to the set of beats present within the electrocardiographic s...

Following years of accepting the Solid Ankle Cushion Heel (SACH) foot as the optimum compromise between durability and functional effectiveness, as well as being of reasonable cost, several new feet with dynamic elastic response qualities have been designed. The stimulus for these new designs is the recent development of materials which offer the potential to "store and release energy" in a man...

We analyze a dynamic contribution game to a public project, in which a group of agents exert costly effort over time to make progress on a project. The project progresses gradually, and it is completed once a pre-specified amount of progress has been made, at which point it generates a lump sum payoff. A standard result in these games is that equilibrium efforts are inefficiently low due to the...

A new approach or model to the dynamic DEA, referred to as the adjusted dynamic DEA, is proposed in this study. Adjusted dynamic DEA optimizes the production activity of DMUs by introducing adjustment variables to modify the interconnecting activities between consecutive terms, solving conflicts that arise between terms and between management and shareholders. The non-oriented SBM model is used...
