Vendor funds are trade deals in which a supplier offers a retailer a short-term discount on a specific product, encouraging the retailer to discount the product. Past vendor funds have had significant shortcomings. In this paper, we propose the pass-through constrained vendor fund in which the supplier requires the retailer to pass-through a minimal fraction of the discount. The vendor fund offer and selection problem is modeled as a bi-level optimization problem in which a supplier wishes to determine what pass- through constrained vendor fund to offer to a retailer that can accept or reject the offer. First, we formulate the lower-level retailer model as an integer quadratic optimization model to help retailers decide on which vendor funds to accept. Using Lagrangian relaxation methods we create an efficient algorithm with theoretical guarantees and near-optimal performance on Oracle Retail client data. Second, we analyze a bi-level supplier model to determine which vendor fund a supplier should offer. We show that the vendor fund with pass- through constraint mitigates forward-buying by the retailer and coordinates supply chains on the short-term.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"26 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2017-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87646752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, this is prevalent in the real-time online display advertising market, in which advertisers bid for impressions through intermediaries called demand side platforms (DSPs). In turn, intermediaries, when bidding on behalf of their customers, strategize to maximize some internal objective and may only submit a single bid to limit competition on a given item. In the present paper, we propose a framework to analyze the implications of such a campaign coordination role by DSPs, taking as a benchmark the case in which each DSP would manage the bidding process of each advertiser it represents independently of other buyers, a case we refer to as multi-bidding. We show that the adoption of multi-bidding by all intermediaries would lead to an increase in both the social welfare and the seller's revenues. Furthermore, we analyze the impact on buyers in two regimes: i.) without competition among intermediaries and ii.) with competition, with a large number of intermediaries and buyers in an appropriate asymptotic regime. Quite remarkably, we establish that multi-bidding would also lead to an increase in the buyers' side surplus under a very broad set of market characteristics. In particular, as long as the average number of buyers interested in an item is moderate and the coefficient of variation of buyers' values is not too small, moving from coordinated campaigns to multi-bidding leads to a Pareto improvement in the value chain.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"48 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2017-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85195673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clearly, inventory could increase sales: expanding inventory creates more choice (options, colors, etc.) and might signal a popular/desirable product. Or, inventory might encourage a consumer to continue her search (e.g., on the theory that she can return if nothing better is found), thereby decreasing sales (a scarcity effect). We seek to identify these effects in U.S. automobile sales. Our primary research challenge is the endogenous relationship between inventory and demand — e.g., dealers influence their inventory in anticipation of demand. Hence, our estimation strategy relies on weather shocks at upstream production facilities to create exogenous variation in downstream dealership inventory. We find that the impact of adding a vehicle of a particular model to a dealer's lot depends on which cars the dealer already has. If the added vehicle expands the available set of sub-models (e.g., adding a four-door among a set that is exclusively two-door), then sales increase. But if the added vehicle is of the same sub-model as an existing vehicle, then sales actually decrease. Hence, expanding variety should be the first priority when adding inventory — adding inventory without expanding variety is actually detrimental. Based on this insight, given a fixed set of cars, vehicles should be allocated among a group of dealers so as to maximize each dealer's variety. Our data indicate that the implementation of this strategy could increase expected sales by about 2.5% without changing the total number of vehicles in the market, which vehicles are produced or the number of vehicles at each dealership. If the firm is willing to reduce aggregate inventory by a modest 2.9% (and no more than 10% at any one dealer), then the sales impact of the \"maximize variety, minimize duplication strategy\" doubles, to 5.0%.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"188 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80696707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Should firms have restrictive returns policies yet unconstrained use of secondary markets for salvaging, thereby risking oversupply and low salvage values? Or should firms have lenient returns policies while limiting the size of their secondary market, thus engaging in repeated and costly refurbishing activities? This paper investigates optimal returns policy decisions in a competitive environment with endogenous salvaging values. The strategic decisions are two components of the retailer's returns policy: price and restocking fee. We consolidate retailer decisions in a duopoly setup under which endogenous salvaging is modeled as an interaction effect between the primary and secondary market. We find that \"smart salvaging\" is more profitable and consumer friendly than charging customers to return products and then salvaging them en masse at rock bottom prices in secondary markets. More specifically: if there are exchanges and salvage values are below unit cost then, at equilibrium, it is optimal for retailers to increase restocking fees and prices, which increases profits but reduces customer satisfaction. When salvage values exceed unit cost, only prices increase while restocking fees are eliminated; which boosts both profits and customer satisfaction. Moreover, retailers that asymmetrically dominate their competitors in terms of salvaging can significantly outperform them with regard not only to sales and profits but also to returns policy leniency. This is a win-win outcome because it increases the utility of retailers and customers alike.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"24 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2017-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72814647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Useful products may be recovered through testing and/or remanufacturing processes. The company must decide on the number of new units to purchase from a production line each period. This decision depends on an array of complex factors including stochastic demand rates, probabilistic yields from both the testing and remanufacturing processes, multiple sources of supply originating from both the stochastic reverse channel and the company's purchasing decisions, and varying levels of information regarding reverse pipeline inventory; we call this latter concept Advance Supply Information (ASI).In this paper we combine all of these elements to formulate a model that analyzes these tactical decisions and the value of ASI in this setting. We use dynamic programming to develop analytical models that determine the optimal ordering decisions under various levels of reverse channel visibility. The curse of dimensionality prohibits us from solving for optimal policies in all cases; thus, we develop heuristic dynamic programs using an aggregated state space that allow for tractable models while incorporating information gained from the pipeline visibility.","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"106 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2016-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79325103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Standby upgrades, where the customer is only charged if the upgrade is available at the time of arrival, is one technique that has become increasingly popular in practice for monetizing the premium room inventory that may otherwise go unused. We develop a model of premium room and standby upgrade pricing under an uncertain market size and examine how and when standby upgrades can provide additional revenue for a hotel. When guests are myopic, we show that standby upgrades can be used as a powerful price discrimination tool, especially for hotel properties with high premium-to-standard room ratios. When guests are strategic, the benefit of standby upgrades is significantly diminished; we show that standby upgrades only increase revenue when the hotel property has a low premium-to-standard room ratio. Our findings thus provide guidance on the hotel types and environments that are most suitable for standby upgrades. \u0000 \u0000The online appendix is available at https://doi.org/10.1287/msom.2016.0596 .","PeriodicalId":49886,"journal":{"name":"Manufacturing Engineering","volume":"46 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2016-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81254377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
