A review of non-cooperative newsvendor games with horizontal inventory interactions

There are numerous applications of game theory in the analysis of supply chains where multiple actors interact with each other in order to reach their own objectives. In this paper we review the use of non-cooperative game theory in inventory management within the newsvendor framework describing a single period inventory control model with the focus on horizontal interactions among multiple independent newsvendors. We develop a framework for identifying these types of horizontal interactions including, for example, the models with the possibility of inventory sharing via transshipments, and situations with substitutable products sold by multiple newsvendors. Based on this framework, we discuss and relate the results of prior research and identify future research opportunities

Canadian Chicken Industry: Consumer Preferences, Industry Structure and Producer Benefits from Investment in Research and Advertising

The Canadian chicken industry has operated under supply management since the mid-1970s. Canadian consumer preferences for chicken have grown dramatically since then possibly in response to concerns about health and the levels of fat and cholesterol in red meats. However Canadian consumers are also looking for convenience with their food purchases. Canadians are buying their chicken in frozen further processed forms, fresh by cut without skin and bone and in a variety of other different ways reflecting their unique willingness to pay for various attributes. There is also an increasing trend for retailers and processors to brand the fresh chicken product sold through grocery stores (for example, Maple Leaf Prime). The preferences Canadian consumer have for various chicken products, the prices they are comfortable paying and the strategies followed by processors/retailers can directly affect the outcomes of industry wide strategies such as investment in generic advertising and research or the impact of international market changes such as border closures. This research is an initial attempt to quantify Canadian consumer preferences – for fresh product by type – for product by level of processing – for chicken product by cut - for fresh chicken by brand - to examine the impact of substitutability on a variety of market shocks. The various different disaggregations of Canadian chicken consumption are used in a number of simulation models to illustrate how important preferences are to producer returns when there are market shocks. If Canadians found all chicken products available in the grocery store to be perfectly substitutable then previous policy analysis assuming chicken is one homogeneous product would be sufficient for industry policy analysis purposes. If Canadians view all the different chicken products as imperfectly substitutable and given that various chicken products are produced in relatively fixed proportions (white and dark meat, for example) further understanding of how consumers make their purchase decisions could enhance the industries ability to predict outcomes. For example, border closing to Canadian exports ( as a result of an Avian influenza outbreak, for example) would result in a significant increase in the dark meat products available for sale through Canadian grocery stores. The results presented in this research could provide a clue as to how much dark meat prices might decline while white meat prices might remain unaffected. The results reported suggest that at the consumer level, chicken fresh and frozen products are not perceived to be perfect substitutes, within a narrow category such as fresh chicken breasts, they are not perceived as even close substitutes, within the fresh category branded products such as those developed by Lilydale and Maple Leaf are not perceived as perfect substitutes. As well, an initial look at the demand for individual chicken products by household suggests that there is far from a common buying pattern across Canadian households, even within a single province. The results also suggest that health and convenience attributes are driving Canadian consumer preferences. Simulation results highlight the fact that pricing strategies followed by major processors/retailers within Canada can influence the returns to generic advertising and research. Further research could provide additional robust estimates of the chicken product substitutability existing in the Canadian market and an increased understanding of the market characteristics currently operating. The results presented here suggest that further work in this area is important for the chicken industry to pursue.consumer behaviour, chicken consumption, differentiated products, Consumer/Household Economics, Demand and Price Analysis, Food Consumption/Nutrition/Food Safety, Marketing, D12, Q11, Q18,

Unions and Productivity, Financial Performance and Investment: International Evidence

If the presence of a union in a workplace or firm raises the pay level, unless productivity rises correspondingly, financial performance is likely to be worse. If the product market is uncompetitive this might imply a simple transfer from capital to labour with no efficiency effects, but is probably more likely to lead to lower investment rates and economic senescence. Therefore the impact of unions on productivity, financial performance and investment is extremely important. This paper distils evidence on such effects from six countries: USA, Canada, UK, Germany, Japan and Australia. It is not possible to use theory to predict unambiguously any union effect on productivity because unions can both enhance and detract from the productivity performance of the workplace or firm. The evidence indicates that, in the USA, workplaces with both high performance work systems and union recognition have higher labour productivity than other workplaces. In the UK previous negative links between unions and labour productivity have been eroded by greater competition and more emphasis on 'partnership' in industrial relations but there is a lingering negative effect of multi-unionism, just as there is in Australia. In Germany the weight of the evidence suggests that the information, consultation and voice role of works councils enhances labour productivity particularly in larger firms. In Japan unions also tend to raise labour productivity via the longer job tenures in union workplaces which makes it more attractive to invest in human capital and through the unpaid personnel manager role played by full-time enterprise union officials in the workplace. Unions will reduce profits if they raise pay and/or lower productivity. The evidence is pretty clear cut: the bulk of studies show that profits or financial performance is inferior in unionised workplaces, firms and sectors than in their non-union counterparts. But the world may be changing. A recent study of small USA entrepreneurial firms found a positive association between unions and profits and in the UK the outlawing of the closed shop, coupled with a lower incidence of multi-unionism has contributed to greater union-management cooperation such that recent studies find no association between unions and profits. North American and German evidence suggests that unionisation reduces investment by around one fifth compared with the investment rate in a non-union workplace. In both Canada and the USA this effect is even felt at low levels of unionisation. The UK evidence is mixed: the most thorough study also finds that union recognition depresses investment, but this adverse effect is offset as density rises. The exception is Japan where union recognition goes hand-in-hand with greater capital intensity.unions, productivity, profits, investment

Empirical analysis of countervailing power in business-to-business bargaining

This paper provides a comprehensive econometric framework for the empirical analysis of countervailing power. It encompasses the two main features of pricing schemes in business-to-business relationships: nonlinear price schedules and bargaining over rents. Disentangling them is critical to the empirical identification of countervailing power. Testable predictions from the theoretical analysis for a pragmatic reduced form empirical pricing model are delineated. This model is readily implementable on the basis of transaction data, routinely collected by antitrust authorities and illustrated using data from the UK brick industry. The paper emphasizes the importance of controlling for endogeneity of volumes and established supply chains and for heterogeneity across buyers and sellers due to intrinsically unobservable outside options

International distribution channel strategies for service products: Case study research on Internet of Things enabled innovative B2B services

This master’s thesis research examines how manufacturing companies in the high-technology industries have crafted their distribution strategies, why the decisions have been made and how the channels are evolving. The main focus of this research is to study how innovative Internet of Things enabled (remote condition monitoring) service products are distributed. The research studies the topic by relating distribution literature to three different theoretical areas, namely, value in relationships, product-technology maturity and market diversity. These approaches were chosen because of their ability to explain dynamism, longitudinal development, and transitions within the channels. The research is a multiple case study that utilizes interviews as a main source of data. The qualitative research pursues to produce knowledge about service product distribution channels. The researcher seeks to investigate which factors affect distribution of remote condition monitoring service products and to reveal contingencies. There were four cases studied as the researcher pursued case comparison and thus, to produce generalization. The study results suggest that the strategies are either direct or dual distribution strategies at introduction phase and then they develop into more cooperative hybrid channels or continue with dual strategy. Value in relationships have effect on dual and hybrid distribution decisions as well as type, intensity and coverage of distribution, but also relates to standardization of distribution strategy. Service product-technology maturity affects channel development related aspects and which channels can be exploited. Market diversity explains utilizing multiple channels in distribution as well as adaptation of strategy. When more markets are penetrated, adaptation pressure increases. When this kind of a service product is sold a lot of value has to be proposed and security related aspects must be addressed in the sales situation through direct interaction. Thus, proactive and competent sales people are important factors for success.fi=Opinnäytetyö kokotekstinä PDF-muodossa.|en=Thesis fulltext in PDF format.|sv=Lärdomsprov tillgängligt som fulltext i PDF-format

Optimization of a Dual-Channel Retailing System with Customer Returns

A plethora of retailers have begun to embrace a dual-channel retailing strategy wherein items are provided to consumers through both an online store and a physical store. As a result of standards and competitive measures, many retailers provide buyers who are unhappy with their purchases with the ability to achieve a full refund. In a dualchannel retailing system, full reimbursements can be done through what is called a crosschannel return, when a buyer purchases a product from an online store and returns it to a physical store. They can also be done through what is called a same-channel return, when a buyer purchases a product from a physical store and returns it back to the physical store, or purchases a product from an online store and returns it back to the online store. No existing research has examined all common types of customer returns in the context of a dual-channel retailing system. Be notified that the practice of cross-returning an item purchased from the physical store back to the online store is not common. Thus, it is not considered in this dissertation. We first study the optimal pricing policies for a centralized and decentralized dual-channel retailer (DCR) with same- and cross-channel returns. We consider two factors: the dual-channel retailer’s performance under centralization with unified and differential pricing schemes, and the dual-channel retailer’s performance under decentralization with the Stackelberg and Nash games. How dual-channel pricing behaviour is impacted by customer preference and rates of customer returns is discussed. In this study, a channel’s sales requests is a linear function of a channel’s own pricing strategy and a cross-channel’s pricing strategy. The second problem is an extension of the first problem. The optimal pricing policies and online channel’s responsiveness level for a centralized and decentralized dual-channel retailer with same- and cross-channel returns are studied. Indeed, the online store is normally the distribution centre of the enterprise and is not limited to the customers in its neighbourhood. Also, the online store experiences a much higher return rate compared to the physical store. Thus, it has the capability and the need to optimize its responsiveness to customer returns along with its pricing strategy. A channel’s sales requests, in the second problem, is a linear function of a channel’s own price, a crosschannel’s price, and the online store’s responsiveness level. The third problem studies the dilemma of whether or not to allow unsatisfactory online purchases to be cross-returned to the physical store. If not properly considered, those returns may create havoc to the system and a retailer might overestimate or underestimate a channel’s order quantity. Therefore, we study and compare between four vi different strategies, and propose models to determine optimal order quantities for each strategy when a dual-channel retailer offers both same and cross-channel returns. Several decision making insights on choosing between the different cross-channel return strategies and some properties of the optimal solutions are presented. From the retailer’s perspective of outsourcing the e-channel’s management to a third party logistics and service provider, we finally study three different inventory strategies, namely transaction-based fee, flat-based fee, and gain sharing. For each strategy, we find both channels’ optimal inventory policies and expected profits. The performances of the different strategies are compared and the managerial insights are given using analytical and numerical analysis. Methodologies, insights, comparative analysis, and computational results are delivered in this dissertation for the above aforementioned problems
