There are two separate customer demands for the new product with two‐period remaining lifetime and the old product with one‐period remaining lifetime, and a fixed proportion of the unsatisfied demand for one product will purchase the other product as a substitute. One distinctive feature of our system is that a random portion of the sold new product is returned and can be remanufactured and remarketed as the old product for sale. The objective is to maximize the expected total discounted profit over a finite planning horizon. We show that the optimal remanufacturing policy is a modified base–stock policy, and that the optimal manufacturing quantity of the new product decreases in the inventory level of the old product after remanufacturing. Furthermore, when the inventory level of the old product is large, the optimal manufacturing quantity asymptotically approaches a constant, which is lower and upper bounded by two newsvendor fractile solutions. We also conduct a numerical study to derive insights into the effects of remanufacturing and demand substitution. In particular, we show that remanufacturing can be a powerful way of mitigating negative environmental impacts in the cut flower industry. Finally, we discuss two model extensions that allow a joint production capacity and a multi‐period lifetime.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122760106","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}

A global track – global value chains/global production networks (GVC/GPNs) – has focused on the increasing interconnectedness of global trading networks and has overlooked the role of the state and the explanatory power of domestic political economy. Meanwhile, a domestic track – including literature on developmental states, industrial policy and political settlements – has tended to take a methodologically nationalist perspective to examine economic transformation in developing countries, with limited reflections on external economic and political pressures. This paper contributes to an emerging stream of literature that examines how the domestic and global scales influence how developing country governments and firms tackle the challenge of economic upgrading. By combining insights from the political settlements and GVC/GPNs literature, this paper examines the Rwandan government’s attempt at upgrading its coffee production to enter specialty coffee markets. It shows how the existing GVC/GPNs literature makes an important contribution to describing how multipolar governance influences the pathways for economic upgrading in Rwanda’s coffee sector, but that even where access is granted, benefits are captive to the demands of international buyers, and gains for some have not translated across the sector. Insights from the political settlements literature showcase how domestic politics influences who benefits from insertion to GVC/GPNs and how the unequal provision of opportunities affects political stability.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"10 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131442025","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}

It constructs an economic model using a bilateral monopoly market structure to analyse how the average profitability varies with the stages in the chain. By introducing a vertical restraint known as quantity fixing, the double marginalization problem arising as a result of bilateral monopoly can be resolved. It demonstrates joint-profit maximizing contracts emerge under quantity fixing parameters whereby the Assembly and downstream retailer eliminate the incentives for vertical integration. This paper also shows the downstream retailer is more profitable than the upstream Manufacturer if (and only if) both the capability and cost effect of Retailer dominates the two counterpart effects of Manufacturer. For the dominance of capability effect, the retailer must have higher monoposonistic market power in the intermediate inputs market than in the final goods market where it acts as a monopolist. As a result, it could extract more surplus from manufacturer rather than consumers. In terms of cost effect, the factor endowment structure differentials are important to the model. The labour intensive nature of the Manufacturer would lead it to the lower average product of labour, generating a lower level of profitability compared with downstream Retailer which is more capital intensive with higher average labour productivity.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123616331","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}

This resulted in a gold mining boom, making gold the main export product and the main source of economic growth of the country. We hypothesize that gold extraction improved population living standards. This paper investigates how the gold boom in Burkina Faso which began in 2007 has affected socioeconomic outcomes. We use a simple theoretical model to motivate the testing of several hypotheses regarding these impacts. Employing a difference-in-differences strategy as well as panel data models, we estimate the impacts using data from household surveys undertaken in 2003 and 2009 and administrative data. Consistent with our model, the results suggest that areas hosting gold extraction have better average living standards in terms of headcount ratios, poverty gaps and household expenditures than do areas without gold. However, the gold boom is also shown to have potentially increased local inequality and child labor in areas with these income gains. These results demonstrate the importance of proactive government policy in mitigating negative welfare impacts.","PeriodicalId":301337,"journal":{"name":"Social Responsibility in Production & Supply Chain Management eJournal","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130409655","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}

We investigate this decision for a retailer who accepts returns of a remanufacturable product. Our formulation considers the cost structures of the two strategies, uncertainty in the input quality of the collected/returned used products, consumer willingness-to-pay for remanufactured product, the extent to which the remanufactured product cannibalizes demand for new product, and the power structure in the channel. \u0000 \u0000For the profit-maximizing retailer the differentials in variable remanufacturing costs drive strategy choice, and higher fixed costs of in-house remanufacturing favors outsourcing. The variable remanufacturing costs and the balance of power in the prospective outsourced reverse channel are the key drivers of environmental impact, as measured by the retailer's propensity to remanufacture. While profitability and environmental goals often conflict, they align under certain conditions. These include (a) the third-party has less bargaining power; or (b) the fixed cost for in-house remanufacturing is relatively high. All else equal, when remanufacturing is outsourced, the environment fares better if the third-party has leadership power. \u0000 \u0000We generalize to the cases when remanufacturing achieves a quality level less than “good-as-new” and when used items have non-zero salvage value. Analysis of these extensions illuminates how relative power in the reverse channel drives the firms’ preferences, as well as the end customers’ consumption experience. \u0000 \u0000This article is protected by copyright.
