摘要：We investigate the effect of regret-related feedback information on bidding behavior in sealed-bid first-price auctions. Two types of regret are possible in this auction format. A winner of the auction may regret paying too much relative to the second highest bid, and a loser may regret missing an opportunity to win at a favorable price. In theory, under very general conditions, being sensitive to winning and paying too much should result in lower average bids, and being sensitive to missing o...

摘要：In this paper, we study a decentralized assembly system consisting of a single assembler who buys complementary components from independent suppliers under two contracting schemes: push and pull. In both schemes, the component suppliers are allowed to freely form coalitions (or alliances) among themselves to better coordinate their pricing or production decisions. We show that the sole driver of the inefficiency in a push system, which is due to horizontal decentralization of suppliers, is the...

摘要：Patch management is a crucial component of information security management. An important problem within this context from a vendor's perspective is to determine how to release patches to fix vulnerabilities in its software. From a firm's perspective, the issue is how to update vulnerable systems with available patches. In this paper, we develop a game-theoretic model to study the strategic interaction between a vendor and a firm in balancing the costs and benefits of patch management. Our obje...

摘要：Sales technology has been touted as a primary tool for enhancing customer relationship management. However, empirical research is sparse concerning the use of information technology (IT) and its effects on the relationship between salespersons and customers. Using an interdisciplinary research approach, we extend task-technology-fit (TTF) theory by examining the mechanisms through which use of IT by the sales force influences salesperson performance. We test a model that incorporates salespers...

摘要：We investigate contracting and information sharing in two competing supply chains, each consisting of one manufacturer and one retailer. The two supply chains are identical, except they may have different investment costs for information sharing. The problem is studied using a two-stage game. In the first stage, the manufacturers decide whether to invest in information sharing. In the second stage, given the information structure created in the first stage, the manufacturers offer contracts to...

摘要：Deterministic inventory theory provides streamlined optimization models that attempt to capture trade-offs in managing the flow of goods through a supply chain. We will consider two well-studied deterministic inventory models, called the one-warehouse multiretailer (OWMR) problem and its special case the joint replenishment problem (JRP), and give approximation algorithms with worst-case performance guarantees. That is, for each instance of the problem, our algorithm produces a solution with c...

摘要：The format of pricing contracts varies substantially across business contexts, a major variable being whether a contract imposes a fixed fee payment. This paper examines how the use of the fixed fee in pricing contracts affects market outcomes of a manufacturer-retailer channel. Standard economic theories predict that channel efficiency increases with the introduction of the fixed fee and is invariant to its framing. We conduct a laboratory experiment to test these predictions. Surprisingly, t...

摘要：Software vulnerabilities represent a serious threat to cybersecurity, most cyberattacks exploit known vulnerabilities. Unfortunately, there is no agreed-upon policy for their disclosure. Disclosure policy (which sets a protected period given to a vendor to release the patch for the vulnerability) indirectly affects the speed and quality of the patch that a vendor develops. Thus, CERT/CC and similar bodies acting in the public interest can use disclosure to influence the behavior of vendors and...

摘要：In this paper, we examine contracts to coordinate the capacity decision of a vendor who has been hired by a client to provide call center support. We consider a variety of contracts, all based on our observations of contracts used by one large vendor. We examine the role of different contract features such as pay-per-time, pay-per-call, service-level agreements, and constraints on service rates and abandonment. We show how different combinations of these contract features enable client firms t...

摘要：Traditional inventory models, with a few exceptions, do not account for the existence of inventory record inaccuracy (IRI), and those that do treat IRI as random. This study explores IRI observed both within and across product categories and retail stores. Examining nearly 370,000 inventory records from 37 stores of one retailer, we find 65% to be inaccurate. We characterize the distribution of IRI and show, using hierarchical linear modeling (HLM), that 26.4% of the total variance in IRI lies...
