• Since Wilkie’s result [9] (which established that the elementary theory Texp of (R, exp) is model complete and o-minimal), many o-minimal expansions of the reals have been investigated. The problem of constructing nonarchimedean models of Texp (and more generally, of an ominimal expansion of the reals) gained much interest. • In [2] it was shown that fields of generalized power series cannot ...

This paper contributes to, and links the areas of quality management and buyersupplier relationships. In doing so, we seek to address two broad research questions. To what extent do quality practices impact upon the various dimensions of quality performance, manufacturing performance and, in turn, business performance? To what extent is the relationship between quality practices and quality per...

This paper characterizes equilibrium behavior in multilateral negotiations, an exchange process in which a buyer attempts to purchase from one of several sellers with privately known production costs. The buyer receives an initial set of price offers, then can try to play the sellers off one another to obtain concessions. Consistent with recent experimental evidence, expected prices in the nego...

In this paper, we consider the single vendor single buyer integrated production inventory problem. We relax the assumption of deterministic demand and assume that the lead time is varying lineraly with the lot size. The lead time is composed of a lot size-dependent run time and constant delay times such as moving, waiting and setup times. A solution procedure is suggested for solving the propos...

Abstract Many studies on buyer–supplier-supplier triads demonstrate the value of interactions between three business actors instead two for identifying triadic collaboration strategies that can lead firms to improve their performance. However, there is little research date has explored which specific lean improvements various types to. This paper fills this gap. We study an automotive supplier ...

This paper studies split-award procurement auctions where a buyer can either divide full production among multiple suppliers or award the entire production to a single supplier. The literature shows that single sourcing usually dominates multiple sourcing. This paper challenges the “winner-takes-all” argument. In a framework of generalized second-price auctions with pre-auction investment, we s...

This dissertation consists of three essays that explore contracts and corporate governance structure issues in the information technology (IT) industry. The first essay shows that when the information technology service being provided is critical to the buyer, it is optimal for the buyer and seller to sign flexible contracts that incorporate future renegotiations. The second essay studies contr...
