In a multi-attribute combinatorial double auction (MACDA), sellers and buyers’ preferences over multiple synergetic goods are best satisfied. In recent studies in MACDA, it is typically assumed that bidders must know the desired combination (and quantity) of items and the bundle price. They do not address a package combination which is the most desirable to a bidder. This study presents a new p...

Optimal mechanisms have been provided in quite general multi-item settings [4], as long as each bidder’s type distribution is given explicitly by listing every type in the support along with its associated probability. In the implicit setting, e.g. when the bidders have additive valuations with independent and/or continuous values for the items, these results do not apply, and it was recently s...

In six experiments, we tested four explanations for the better/worse-than-average effect (B/WTA) bymanipulating the number of items comprising the target or referent of direct comparison. A single-item target tended to be rated more extremely ...

We investigated automatic action item detection from transcripts of multi-party meetings. Unlike previous work (Gruenstein et al., 2005), we use a new hierarchical annotation scheme based on the roles utterances play in the action item assignment process, and propose an approach to automatic detection that promises improved classification accuracy while enabling the extraction of useful informa...

This study is concerned with the optimal common cycle time for a multi-item production system with discontinuous delivery and failure in rework. In real life manufacturing environments, managements often plan to produce multiple products in turn on a single machine in order to maximize machine utilization. Also, dealing with random defective items during production seems to be an inevitable tas...

A multi-party fair exchange protocol is a cryptographic protocol allowing several parties to exchange commodities in such a way that everyone gives an item away if and only if it receives an item in return. In this paper we discuss a multi-party fair exchange protocol originally proposed by Franklin and Tsudik, and subsequently shown to have flaws and fixed by González and Markowitch. We identi...

Psychological literacy, the ability to apply psychological knowledge to personal, family, occupational, community and societal challenges, is promoted as the primary outcome of an undergraduate education in psychology. As the concept of psychological literacy becomes increasingly adopted as the core business of undergraduate psychology training courses world-wide, there is urgent need for the c...

In this paper we explore and analyze the structure of Internet auctions from an analytical and an empirical perspective. Such web-based auctions are rapidly emerging as a mercantile process of choice in the electronic marketplace. We observe current Internet auctions for one-time products, such as rapidly aging hardware, and analyze them within the framework of the existing auction theory. Whil...

We study inventory control for rental operations in a closed-loop supply chain. In such a system (e.g., Netflix), customers create online queues in a service provider’s website to indicate the items that they would like to rent. Leveraging this advance demand information, we propose effective forecast models and formulate a multi-item inventory control problem. We prove that the (L,U) policy is...

We analyze ex-post implementable social choice functions for private-value and quasi-linear settings over restricted domains of preferences, the leading example being multi-item auctions (with either heterogeneous or homogeneous goods). Our work generalizes the characterization of Roberts (1979) who characterized ex-post implementability over unrestricted domains. We show that ex-post implement...
