ILO declared this virus as a labor market and economic crisis. This study has been conducted for understanding the effect of COVID-19 on the apparel industry and the apparel manufacturing workers. This is a descriptive study, following the inductive procedure. The relevant information has been collected from the current academic literature, newspapers, reports publications, and relevant web pages. An online interview with the manufacturers, policymakers, trade unions, researchers, and academicians has been conducted for primary information collection. This study has found that the apparel industry is one of the most affected industries among the other industries by COVID-19. The retailers’ shops are being closed with having zero turnovers which leads to ordering cancelation to the manufacturing factories. Bangladesh's apparel manufacturing industry is also drastically affected due to COVID-19. The factories can’t pay the workers’ salaries in this critical situation. Therefore, millions of workers have been sent home without their wages. Sometimes, it has predicted that the workers would lose jobs due to factory closure. The Government took lots of initiatives i.e. tax rebates, reduce VAT, financial support to the owners to pay the workers’ wages, loan installment rescheduling, etc. Albeit, these initiatives were taken for the welfare of the factory owners and the workers remain oppressed. So, a proper policy strategy is indeed an emergency to support the destitute workforce during the COVID-19 as well as in future financial crises that can happen due to this kind of epidemic or any reason. This study will be supportive to the stakeholders of this sector to learn the impact of COVID-19 on the workers and make the necessary adjustment for the future betterment.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124322898","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}

Demand interdependence (product substitutability) among various brands is critical and thus we investigate its impact on ﬁrms’ proﬁts. Using an economic framework with manufacturers operating as Stackelberg leaders, our analysis reveals unique and substantive insights dependent on the underlying market demand structure, and in some cases, the extent of supply coverage. For the Spence-Dixit-Vives demand structure, we ﬁnd that competing manufacturers prefer to oﬀer brands with low levels of substitutability while retailer’s preferences are moderated by the interaction eﬀect between the number of competing brands and level of product substitutability (essentially the retailer prefers high levels of substitutability when the number of brands is “small,” and vice versa). For the Shubik-Levitan demand structure, manufacturers may prefer high or low levels of product substitutability depending on the extent of supply coverage while the retailer always prefers high levels of product substitutability. These ﬁndings oﬀer useful prescriptions for category management and persuasive advertising.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133538380","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 OEM can contract with the two suppliers either simultaneously or sequentially. We consider both cases in which the OEM has relatively equal bargaining power (the dynamic bargaining institution) or substantial bargaining power (the mechanism design institution). For the dynamic bargaining institution, we show that in sequential bargaining, the supply chain profit is higher, the OEM earns a lower profit, the first supplier earns a higher profit, and the second supplier may earn a higher or lower profit, than compared with simultaneous bargaining. For the mechanism design institution, we show that all players’ profits are the same in simultaneous and sequential contracting. We also benchmark against a case where the OEM procures both inputs from a single integrated supplier (a dyadic supply chain). We then test these predictions in a human-subjects experiment, which supports many of the normative predictions qualitatively with some deviations: an OEM with relatively equal bargaining power weakly prefers to contract with suppliers simultaneously, whereas an OEM with substantial bargaining power prefers to contract with suppliers sequentially. In addition, the OEM’s profit and supply chain efficiency are higher in the dyadic supply chain than the assembly system.

The consumers in each channel are heterogeneous such that the product fits the tastes of only a fraction of these consumers. The retailer provides a product description for each channel to help the consumers assess whether the product fits their tastes. The two channels are either operated separately with different product description levels or integrated with a common product description level. We construct a two-period game-theoretical model in which the retailer optimizes the product description levels to maximize her expected profit. We find that integrating the offline and online channels yields more profit to the retailer if and only if the offline channel's product description limit and the consumers' base product valuation are small. We further consider a review system where the consumers who purchase the product in period 1 may post their reviews. The fraction of positive reviews in period 1 will influence the purchase intention of the upcoming consumers in period 2. In the presence of the consumer reviews, even if the offline product description limit is large, it can still be more profitable to integrate the offline and online channels. Furthermore, the consumer reviews may reduce the retailer's profit if the consumers' base product valuation is sufficiently large.","PeriodicalId":129698,"journal":{"name":"Supply Chain Management eJournal","volume":"150 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116696008","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}

Their success depends on their ability to assign experienced and skilled workers to specialized tasks and coordinate work on production lines. Worker turnover may disrupt such efforts. We use staffing, productivity, and pay data from within a major consumer electronics manufacturer’s supply chain to study how firms should manage worker turnover and its effects using production decisions, wages, and inventory. We find that worker turnover impedes coordination between assembly line coworkers by weakening knowledge sharing and relationships. Publicly available unit-cost estimates imply that worker turnover accounts for $206–274 million in added direct expenses alone from defectively assembled units failing the firm’s stringent quality control. To evaluate managerial alternatives, we structurally estimate a dynamic equilibrium model (an Experience-Based Equilibrium) encompassing (1) workers’ endogenous turnover decisions and (2) the firm’s weekly planning of its production scheduling and staffing in response. In counterfactual analyses, a less turnover-prone, hence more productive, workforce significantly benefits the firm, reducing its variable production costs by 4.5%, or an estimated $928 million for the studied product. Such benefits justify paying higher efficiency wages even to less skilled workforces; furthermore, interestingly, rational inventory management policies incentivize self-interested firms to reduce rather than tolerate turnover.

We examine the signaling role of buyback contracts when the retailer is less informed about either the manufacturer’s reliability of honoring the buyback commitment (e.g., for a small/less-established manufacturer) or its product’s market potential (e.g., for a national brand manufacturer). We find that these two situations yield contrasting buyback designs: the manufacturer must distort the wholesale and returns prices downward to signal higher reliability, but upward to signal higher market potential. Nevertheless, the signaling mechanism in both cases hinges on suitably distorting the manufacturer’s returns cost (i.e., the cost of repurchasing a retailer’s unsold inventory) by influencing the retailer’s regular stock (i.e., the portion of inventory carried to meet average demand) and safety stock (i.e., the extra inventory carried to meet potential high demand). Notably, although prior research has highlighted the signaling role of the wholesale price, we show how and why, in a channel with inventory, the returns price plays a relatively more important role. In particular, efficient signaling entails that the returns price is used to distort the manufacturer’s returns cost, whereas the wholesale price is used only to mitigate the resulting distortion in the retailer’s order quantity. In fact, the returns price emerges as a more efficient signaling instrument and reverses the direction of wholesale price distortion from what is necessary if wholesale price alone is used to signal. We also examine the implications when the two dimensions of manufacturer’s private information are correlated.
