The need for new procurement auction mechanisms that allow for rich bid types such as bundle bids on multiple items has been raised in many situations in industrial procurement. In addition to strategic problems, the design of these combinatorial auctions exhibits hard computational problems. For example, the winner determination typically leads to NP-hard allocation problems in combinatorial a...

From June 1994 to June 1995, producer prices increased rapidly. Excluding food and energy, prices of crude materials and intermediate goods rose at annual rates of 7.2 and 16.7 percent, respectively. At the same time, however, prices of consumer goods and services excluding food and energy increased a more modest 2.9 percent. Many analysts are concerned that recent increases in the prices of cr...

The proliferating cost with-in the healthcare domain is forcing the researchers and practitioners alike to revisit healthcare logistics domain again and again in order to control the cost. However, controlling healthcare cost requires that limits be placed either on prices, quantities of services or both. As prices can be easily controlled by effectively focusing on the mechanism rather then in...

In this paper, I present strong statistical evidence of the pervasiveness of official diversion in China’s industrial planning bureaucracy under the dual-track system. The underpricing of in-plan goods and the ensuing shortage in the plan led to gains from trade between officials who controlled the allocation of in-plan goods and customers willing to pay more than the plan prices. By diverting ...

We provide a broad characterization of the supply chain settings in which perfect coordination can be achieved with a simple wholesale pricing scheme based on constant unit wholesale prices or a single quantity discount scheme. We confine ourselves to two-echelon chains with a single supplier servicing a network of retailers who compete with each other by selecting retail prices (Bertrand compe...
