Online reputation -"feedback"- mechanism aim to mitigate the moral hazard problem associated with spatially distant exchange among strangers by providing traders with the type of information available in small groups, where members are frequently involved in another's dealings. We compare...

Electronic reputation or "feedback" mechanisms aim to mitigate the moral hazard problems associated with exchange among strangers by providing the type of information available in more traditional close-knit groups, where members are frequently involved in one another's dealings. In this paper,...

Reciprocity in feedback giving distorts the production and content of reputation information in a market, hampering trust and trade efficiency. Guided by feedback patterns observed on eBay and other platforms, we run laboratory experiments to investigate how reciprocity can be managed by changes...

We compare how experienced procurement managers and students solve the newsvendor problem. We find that managers broadly exhibit the same kind of pull-to-center bias as students do. Also, managers use information and task training no better than students. The performance of managers is...

Complexity of communication is one of the important factors that distinguishes multilateral negotiation from its bilateral cousin. We investigate how the communication configuration affects a three-person coalition negotiation. Restricting who can communicate with whom strongly influences...

The strength of bargainers' preferences for fair settlements has important implications for predicting negotiation outcomes and guiding bargaining strategy. Existing literature reports a few calibration exercises for social utility models, but the predictive accuracy of these models for...

We study a procurement setting in which the buyer seeks a low price but will not allocate the contract to a supplier who has not passed qualification screening. Qualification screening is costly for the buyer, involving product tests, site visits, and interviews. In addition to a qualified...

Most business-to-business (B2B) auctions are used to transact large quantities of homogeneous goods, and therefore use multiunit mechanisms. In the B2B context, bidders often have increasing returns to scale, or synergies. We compare two commonly used auction formats for selling multiple...

We investigate how auctioneers set reserve prices in auctions. A well-established theoretical result, assuming risk neutrality of the seller, is that the optimal reserve price should not depend on the number of participating bidders. In a set of controlled laboratory experiments, we find that...

We introduce a heuristic method for finding good, feasible solutions for multiproduct lot sizing problems with general assembly structures, multiple constrained resources, and nonzero setup costs and setup times. We evaluate the performance of this heuristic by comparing its solutions to optimal...
