Methodology/results: We build on the classical agency model by incorporating the supply/demand mismatch and inventory ordering delegation. We derive the closed-form expression for the firm's optimal compensation scheme in the most general contract space and show that it takes a simple form, coupling the classical linear compensation scheme with a compensation component contingent on some operational metric. Managerial implications: First, the firm should include a compensation component that is tied to operational metrics such as the sales division's leftover inventory and the unfulfilled demand. Second, the optimal compensation scheme needs to be adapted to the distinct operational features such as demand being censored or not, lost sales or backorder. Third, the optimal compensation scheme possesses the property of piece-wise linearity in demand (or sales) with a drop in the commission rate after demand exceeds the available inventory. This is in contrast not only with the classical linear compensation scheme, but also with the quota-based compensation scheme featuring a progressively increased commission rate when the demand exceeds a prespecified quota.","PeriodicalId":330843,"journal":{"name":"PROD: Analytical (Supply) (Topic)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122358087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manufacturers produce partially substitutable products, which are stocked by the retailer that sells them in the market characterized by random demand. The manufacturers are privately informed about uncertain demand and decide on whether to share this information with the retailer. We show that by not sharing information, a manufacturer ends up distorting its wholesale price upward to signal its private information to the retailer, and under upstream competition, this distortion is propagated to the competing manufacturer. Thus, although a manufacturer’s decision to not share information may benefit or hurt its own profit, this always benefits the competing manufacturer. Under low intensity of competition, signaling-driven distortions exacerbate double marginalization and hurt all parties, whereas under more intense competition, these distortions help manufacturers offset downward pressure on wholesale prices. Thus, in equilibrium similarly informed manufacturers share information in the former case but not in the latter case. Additionally, when manufacturers differ in their information accuracies, only the better-informed manufacturer shares information. The retailer always benefits from both manufacturers sharing information, and its benefits are larger when the better-informed manufacturer shares information. We show existence of a contracting mechanism the retailer can employ to enable information sharing. Finally, we analyze manufacturers’ information acquisition decisions and find that under competition, two manufacturers acquire minimal information so that they are better off not sharing information in the information sharing game.

When the supplier sells goods through an online channel in addition to a traditional retailer, it should either select a conventional wholesale contract or an emerging agency contract. Under the agency contract, the supplier can directly set its retail price while sales revenues are split with the platform according to a royalty rate (also called a commission rate). The platform should determine its optimal royalty rate by considering the supplier's decision on which contract to select. I show that the royalty rate is set at the highest level possible while still inducing the supplier to choose the agency contract, above which, the wholesale contract is chosen. Moreover, compared with when the supplier does not encroach, adding the online channel is beneficial to the encroaching supplier but is detrimental to the traditional retailer. More interestingly, all firms (a supplier, retailer, and platform) can benefit from recent industrial changes from traditional wholesale agreements toward agency agreements when brick-and-mortar and online channels are highly substitutable.","PeriodicalId":330843,"journal":{"name":"PROD: Analytical (Supply) (Topic)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130260195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With BOGO, the first unit is sold for the regular price, and the second unit is discounted. We analyze BOGO in manufacturer–retailer supply chains. We identify conditions under which BOGO outperforms price reduction (PR) and everyday low price (EDLP) policies. We find that, for some products, whether consumers stockpile or not, if BOGO and PR have the same market size, BOGO has a larger retailer profit and the same or larger manufacturer profit because BOGO induces more consumers to buy and consume two units. When consumers stockpile, the retailer sets prices to prevent such behavior, and the retailer’s share of supply chain profits is largest under BOGO, whereas consumer surplus with BOGO is smaller than PR. We also find that BOGO reduces double marginalization. When PR expands market size more than BOGO, BOGO’s effectiveness diminishes. When consumers stockpile without increasing consumption and/or production cost is high, EDLP is best. Our results are robust to multiperiod with single-promotion-period settings. A large number of regular-price periods following a promotion period increases stockpiling, which erodes the retailer’s profit and favors EDLP. If promotions are offered for consecutive periods, a larger number of promotion periods increases PR’s efficacy relative to BOGO. Time-inconsistent consumers increase stockpiling and make PR outperform BOGO. Heterogeneous consumers’ holding cost and marginal utility prevent retailers from perfectly discriminating among consumers who make profit-reducing choices. Compared with retailers’ BOGO, manufacturers’ BOGO increases double marginalization and decreases retailers’ and manufacturers’ profits and consumer surplus.

In such networks, any negative publicity from suppliers' noncompliance of socially-responsible practices – e.g., employment of child labor, unsafe working conditions, and excessive pollution – can significantly damage the reputation of the buying firms. To mitigate this impact, firms preemptively audit suppliers, although resource and time considerations typically restrict the number of suppliers a firm can audit. Therefore, a key question is whether firms should prioritize the auditing of suppliers with low or high centrality, ceteris paribus.

Academic/practical relevance: The supply chain is subject to the classic hold-up problem—as the lack of a contract commitment hinders suppliers’ incentives to make investment upfront—complicated with supplier competition. Methodology: With deterministic cost-reduction outcomes, suppliers will not exert any effort if this effort is observable, and a pure-strategy equilibrium does not exist if the effort is unobservable. We analyze the mixed-strategy equilibrium with unobservable supplier effort, in which suppliers randomize their efforts and the buyer designs an optimal procurement mechanism. Results: We show that the optimal procurement mechanism can be implemented by a conventional single-price reverse auction with a random reserve price. The mixed strategy of supplier effort generates endogenous information asymmetry on supplier costs that provides suppliers with information rent, which sustains their efforts. The endogenous information asymmetry improves effort efficiency (by inducing positive supplier effort), yet introduces trade inefficiency (by causing the possible failure of trade between the parties). Although increasing supplier competition (measured by the number of suppliers) hurts the effort efficiency, it improves trade efficiency. As a result, the buyer is always better off introducing supplier competition by including more than one supplier in the supply base. However, the desired supply base size (number of suppliers) depends on the product revenue: For high-margin goods, the optimal size is achieved with two suppliers, whereas for low-margin goods, a larger supply base is better for the buyer. We show that the result based on deterministic cost reduction can be established as a limit of the case when uncertainty in cost reduction exists and shrinks to null. Managerial implications: Our study helps to understand the impact of supplier competition when supply-chain parties deliberately make their actions unpredictable to avoid being held up. The findings provide managerial guidance on procurement auction and supply base designs.","PeriodicalId":330843,"journal":{"name":"PROD: Analytical (Supply) (Topic)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128949266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, a growing number of suppliers have opened their direct sales channel and started to match downstream retailers' prices. In this paper, we investigate the efficacy of PMGs on channel coordination and competition in the dual-channel setting. We find that the interaction of the relative channel power and channel substitutability moderates the effectiveness of PMGs by supply chain entities. More specifically, when the relative channel power of the retail channel over the direct channel is small, unilateral PMGs by the supplier decreases both supply chain entities' profits; when the relative channel power of the retail channel over the direct channel is medium and channel substitutability is not high, unilateral PMGs by the supplier benefits both supply chain entities. The intuition behind these results hinges on the trade-off between price competition and revenue allocation. In addition, we investigate the Nash equilibrium outcome when both the supplier and the retailer have the option to offer PMGs. We show that, the retailer weakly prefers not to offer PMGs, the supplier weakly prefers to (not to) offer PMGs when the relative channel power of the retail channel over the direct channel is high (low). Our findings not only complement the PMGs literature, but also provide a new channel coordinating mechanism concerning the channel members' pricing strategies.","PeriodicalId":330843,"journal":{"name":"PROD: Analytical (Supply) (Topic)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133613604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
