This paper studies a general two-stage scheduling problem, in which jobs of different importance are processed by one first-stage processor and then, in the second stage, the completed jobs need to be batch delivered to various pre-specified destinations in one of a number of available...

In this paper, we consider a class of convex nonlinear knapsack problems in which all decision variables are integer and the objective and knapsack functions are nonlinear. This generalized problem is characterized by positive marginal cost (PMC) and increasing marginal loss-cost ratio (IMLCR)....

Over the past year we have researched the development of a network-based real-time laser-based nonintrusive field-deployable detection for the delineation of moving vehicles. The primary goal of this project is to develop a roadway detection system that can be used to gather reliable travel time...

A new version of a field-deployable real-time laser-based detection system has been developed using new techniques of electronics and optics. The laser-based non-intrusive detection system uses a laser line that is projected onto the ground as a probe. The reflected light is collected and...

Zhao (2008) presents an interesting "all-or-nothing monitoring" result for a multitask moral hazard agency problem with partial effort observation. We argue that the optimal contract based on the non-verifiable observation of the agent's effort in Zhao (2008) can be regarded as a limitation on...

We study revenue-maximizing mechanisms for a seller who sells an indivisible good to several buyers with positive, type-dependent and countervailing allocative externalities. To cope with the difficulty of types obtaining reservation utilities being endogenously determined, we first solve a...

This paper measures economic integration in the Asia-Pacific (AP) region using a composite index. The weights of the index are obtained from a two-stage principal component analysis. In the first stage, we obtain a convergence index to measure the extent of convergence among the main...
