In particular, existing operations management articles have discussed the impact of comparison effects on enterprises' production and pricing decisions. Research has also shown that consumers' purchasing decisions are primarily determined by three factors: product quality, selling price, and comparison effects. The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist’s production quality and pricing strategy for substitutable products. Results reveal the following: (1) Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model. (2) The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices. (3) When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products, the monopolist’s optimal choice in the second stage is to keep production quality constant and increase the selling price. Consequently, the number of buyers does not decrease because of temporal comparison effects. Therefore, the firm increases its revenue. (4) For the market with two substitutable products with quality differences, one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period. At this point, the consumption situation in the market is the same as that in the first stage. Therefore, when no external constraints exist, the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage. (5) When consumer identity information can be confirmed in the market, social comparison effects, similar to temporal comparison effects, could help the enterprise increase its price and profit while maintaining product quality. These social and temporal comparison effects constrain consumers. Thus, the number of people who continue to buy products does not decrease.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 4","pages":"Pages 529-557"},"PeriodicalIF":0.0,"publicationDate":"2023-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48866916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To decrease the negative influence of online uncertainty, the largest Chinese e-commerce company, the Alibaba Group, invited an insurance company to develop return-freight insurance (RFI), a new kind of insurance, to compensate for consumers' losses in the event of online product returns. Complimentary RFI can increase consumer confidence in the retailer and attract more demand. Retailers who offer complimentary RFI demonstrate to consumers that their products and services are too good to incur excessive product returns. However, some low-quality online retailers can mimic competitors’ behavior by offering complimentary RFI to consumers. This study aims to introduce an innovative online return policy based on RFI and to explore whether low-quality online retailers would use complimentary RFI as their return strategy to mislead consumers. Using signaling theory, we built a conceptual economic model that includes three exogenous pricing variables: RFI, insurance premium, and compensation. These variables play different roles in the model because consumers cannot observe the insurance premium, but the compensation can be. The main finding of this study is that innovative complimentary RFI could be abused by low-type retailers when the premium and compensation are appropriate. Interestingly, compensation plays different roles for retailers with different product values: low-type retailers use complimentary RFI as a noise tool. When the product works for the consumer and the insurance profit is not too high, the compensation for the low-quality product should be larger than that for the high-quality product, which is different from conventional wisdom. Although high-type online retailers may use complimentary RFI as a product quality signal, there is still a significant risk that nefarious elements will use it to create product quality noise.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 2","pages":"Pages 244-257"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44259516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We tested the performance of our algorithm using a modern MIP solver (Gurobi) and real data from a 3D printing factory.

This study develops an analytical model to study the green investment choices of two differentiated retailers dealing with a common green manufacturer. It also explores the impacts of these investment choices on the manufacturer's operational decisions, channel efficiency, consumer welfare, and the environment. We derive three main results. First, the powerful retailer always favors green investments, whereas the less powerful (inferior) retailer may either prefer or avoid green investments. The fiercer the inter-retailer competition, the lower the willingness of the inferior retailer to introduce green investments. Second, although all supply chain parties may disagree on their preferences for retailers' green investments, a bilateral green investment (i.e., both retailers make green investments) can reach an incentive alignment for all firms if the differentiation between retailers is low enough and the competition between them is not substantially fierce. Moreover, a bilateral green investment improves consumer welfare and channel efficiency because of the great demand expansion and double marginalization reduction. Third, the retailers' green investments can motivate the manufacturer to produce greener products, but they do not necessarily benefit the environment. We show that the supply chain's economic sustainability aligns with its environmental sustainability only if the environmental improvement efficiency of green investments is substantially high. We further examine the impact of retailers with differentiated green investment abilities and the manufacturer's green investment efficiency to verify the robustness of the main results.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 4","pages":"Pages 465-489"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43070972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
