Evidence has documented that social ties improve the chances of publication in journals, whereas building and maintaining social ties require resources. We develop a simple model to investigate the consequences of monetary investment on the probability of publication through social ties. The results indicate that monetary incentive can stimulate researchers to make more efforts regarding publication. Through social ties, monetary investment in the process of academic publication distorts researchers' incentive. Monetary investment through social ties improves the probability of publication and then disables the signaling function of publication in terms of researchers’ abilities. Depending on the contribution of different types of researchers to society and the ability of the latter to differentiate the quality of publication in journals, the improvement in publication probability by monetary investment through social ties may improve or reduce the level of social welfare.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 4","pages":"Pages 490-497"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44366040","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}

{"title":"Retailers’ incentives for green investment in differentiated competition channels","authors":"Xinxin Zhang ,&nbsp;Junran Huang ,&nbsp;Chenglin Shen","doi":"10.1016/j.jmse.2023.03.002","DOIUrl":"10.1016/j.jmse.2023.03.002","url":null,"abstract":"<div><p>With increasing public environmental awareness, green activities in retail and distribution processes have become crucial tools for retailers to boost demand and enhance competitiveness. 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":"2023-12-01","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}

How does uncertainty affect economic activity, and how effective is a NIRP based on central bank digital currency (CBDC)? To answer the two questions, we constructed a dynamic stochastic general equilibrium (DSGE) model that accommodates sticky prices and wages. The results indicated: (i) Economic uncertainty has substantially reduced investment, output, wage, and loans, which increases unemployment risk. In the short term, it has triggered impulsive consumption by households, while consumption has fallen into a slump in the long run. (ii) After suffering an uncertainty shock, the economy entered short-term stagflation and long-term deflation. The short-term stagflation was mainly caused by resident wage adjustment, and the long-term deflation was due to the decline in effective demand caused by unemployment risk. (iii) CBDC could eliminate the zero lower bound (ZLB) constraint, thereby improving the effectiveness of NIRP. Compared with traditional currency, CBDC-based NIRP could more effectively smooth macroeconomic fluctuations and alleviate the negative impact of an uncertainty shock, which is more conducive to restoring market confidence and promoting economic recovery.</p></div>","PeriodicalId":36172,"journal":{"name":"Journal of Management Science and Engineering","volume":"8 4","pages":"Pages 430-452"},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42728304","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}

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":"2023-12-01","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}

This study examines the effect of China's high-speed railway (HSR) on technology inflow, with an emphasis on talent interaction in the technology transfer process. The findings suggest that HSR mitigates cross-city commuting costs and facilitates face-to-face interactions between talent, thereby fostering an increase in technology inflows to various cities. “Talent” use HSR to transfer knowledge to cities teeming with such talent resources. Concurrently, areas with robust intellectual property rights protection witness an upsurge in intercity technology transfer via HSR.
