a two echelon sustainable supply chain coordination under cap and trade regulation this paper analyses the decision behaviour and coordination mechanisms for a two echelon sustainable supply chain under a cap and trade regulation in a make to order setting carbon emissions are generated primarily by the downstream manufacturing process and the market demand of the supply chain is affected by two decision variables the sustainability level and the selling price the impact of the unit emissions trading price on the optimal decision variables in both centralized and decentralized systems is revealed the comparison of decentralized and centralized systems shows that the increase in total profit in centralized system is at most 1 3 that in decentralized system to achieve the same profit as the centralized system we consider two contracts to coordinate the sustainable supply chain revenue sharing and two part tariff contracts by analysing the conditions for a win win outcome we prove that only the two part tariff contract can lead to perfect coordination finally sensitivity analysis of the key parameters is undertaken as part of a numerical example illustrating the theoretical results

using a policy mix for pollution control a review of economic literature this article provides a review of economic studies analyzing the use of multiple policies a socalled policy mix to cope with single pollution problems to guide and structure the review an analytical framework is developed and applied the framework integrates transaction costs into the analysis of pollution problems and policies to overcome them moreover it understands a pollution externality not only as a market failure but more generally as the failure of private governance structures based on this insight two rationales for using a policy mix are identified first a policy mix may help to correct for multiple reinforcing failures of private governance structures such as pollution externalities and technological spillovers second a policy mix can be employed if the implementation of single first best policies brings about high transaction costs e g when marginal pollution damages are heterogeneous or polluters are unlikely to comply with the policy for each rationale the relevant literature is presented based on the review avenues for future research are identified

the impact of sharing customer returns information in a supply chain with and without a buyback policy in this paper we examine a single period problem in a supply chain in which a stackelberg manufacturer supplies a product to a retailer who faces customer returns and demand uncertainty we show that the manufacturer incurs a significant profit loss with and without a buyback policy if it fails to account for customer returns in the wholesale price decision under the assumption that the retailer is better informed than the manufacturer on customer returns information we show that without a buyback policy the retailer prefers not to share if the manufacturer overestimates while it prefers to share customer returns information if the manufacturer underestimates this information if the manufacturer offers a buyback policy we have the opposite results we also discuss incentives to share the customer returns information and some of the issues that are raised in sharing this information

reverse channel design the case of competing retailers the economical and environmental benefits of product remanufacturing have been widely recognized in the literature and in practice in this paper we focus on the interaction between a manufacturers reverse channel choice to collect postconsumer goods and the strategic product pricing decisions in the forward channel when retailing is competitive to this end we model a direct product collection system in which the manufacturer collects used products directly from the consumers e g print and copy cartridges and an indirect product collection system in which the retailers act as product return points e g single use cameras cellular phones we first examine how the allocation of product collection to retailers impacts their strategic behavior in the product market and we discuss the economic trade offs the manufacturer faces while choosing an optimal reverse channel structure when a direct collection system is used channel profits are driven by the impact of scale of returns on collection effort whereas in the indirect reverse channel supply chain profits are driven by the competitive interaction between the retailers subsequently we show that the buy back payments transfered to the retailers for postconsumer goods provide a wholesale pricing flexibility that can be used to price discriminate between retailers of different profitability

sustainability in electrical and electronic equipment closed loop supply chains a system dynamics approach abstract in this paper we examine the impact of ecological motivation and technological innovations on the long term behavior of a closed loop supply chain with recycling activities ecological motivation manifests through legislation and green image factor whereas technological innovations manifest through design for environment we adopt system dynamics methodology applied to many environmental systems seeking long term gains the developed model is implemented to a real world supply chain of electrical equipment in greece numerical analysis illustrates the factors concerned like the delay of the legislation enforcement to achieve a sustainable future through non renewable resources and landfill preservation

economic efficiency effects of alternative policies for reducing waste disposal abstract reducing the amount of municipal solid waste that is disposed of has become an important policy goal previous research argued that a virgin material tax offered an efficient method of meeting this goal and it continues to be considered as a policy option today this paper demonstrates however that a virgin material tax is not an efficient method of reducing waste but that an alternative policy a combined disposal tax and reuse subsidy is the combined disposal tax and reuse subsidy is theoretically consistent with unit based household charges for waste disposal but may have advantages in some situations

scrap prices waste and recycling policy this study examines the effect of waste and recycling policy on scrap prices and the importance of scrap price feedbacks as a determinant of policy costs price effects and direct and indirect channels of waste reduction are decomposed for deposit refund advance disposal fee and recycling subsidies scrap price feedbacks decrease the cost of advance disposal fees increase the cost of recycling subsidies and have an ambiguous effect on the cost of deposit refund simulation analysis finds that scrap price feedbacks substantially affect the costs of the policies and alter the ranking of instruments jel q53 q58

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

is economic growth improving urbanisation a cross regional study of china this study applies a bootstrap panel granger causality test to determine the relationship between urbanisation and economic growth for china we find that the patterns of interaction between urbanisation and economic growth vary across different regions the empirical results show that in urbanisation of the northern coastal region and most of the inland region granger causes economic growth whereas economic growth does not have a significant effect on urbanisation except in the southern coastal region and the inland region one fourth of china s provinces primarily in the southern coastal region do not show a granger causality relationship between urbanisation and economic growth this finding indicates that urbanisation has promoted economic growth by expanding demand and that economic growth s effect on urbanisation is restricted by administrative intervention rather than market mechanisms thus the findings for three fourths of the provinces in china conform to the urbanised economy theory these

garbage recycling and illicit burning or dumping abstract with garbage and recycling as the only two disposal options we confirm prior results that the optimal curbside fee for garbage collection equals the direct resource cost plus external environment cost when illicit burning or dumping is a third disposal option that cannot be taxed directly the optimal curbside tax on garbage changes sign the optimal fee structure is a deposit refund system a tax on all output plus a rebate on proper disposal through either recycling or garbage collection the output tax helps achieve the first best allocation even though it affects the choice between consumption and untaxed leisure

design of sustainable supply chains under the emission trading scheme increase in environmental concerns together with legislations are forcing industries to take a fresh look at the impact of their supply chain operations on the environment this paper introduces a mixed integer linear programming based framework for sustainable supply chain design that considers life cycle assessment lca principles in addition to the traditional material balance constraints at each node in the supply chain indeed the framework distinguishes between solid and liquid wastes as well as gaseous emissions due to various production processes and transportation systems the framework is used to evaluate the tradeoffs between economic and environmental objectives under various cost and operating strategies in the aluminum industry the results suggest that current legislation and emission trading schemes ets must be strengthened and harmonized at the global level in order to drive a meaningful environmental strategy moreover the model demonstrates that efficient carbon management strategies will help decision makers to achieve sustainability objectives in a cost effective manner

upstream pollution downstream waste disposal and the design of comprehensive environmental policies abstract many policymakers are shifting their focus from media specific pollution problems to product specific life cycle environmental problems in this paper we develop a model of production and consumption that incorporates life cycle externalities and use it to solve for alternative policies to achieve a social optimum in general we find that no single instrument can solve multiple problems contrary to what some observers have suggested however we find that there are alternative ways of reaching the social optimum we also discover that an integrated approach to policy appears to be important no matter what policy options are adopted and finally we find that there is only a limited role for so called product life cycle assessments

the credibility revolution in empirical economics how better research design is taking the con out of econometrics since edward leamer s memorable 1983 paper let s take the con out of econometrics empirical microeconomics has experienced a credibility revolution while leamer s suggested remedy sensitivity analysis has played a role in this we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs the advantages of a good research design are perhaps most easily apparent in research using random assignment we begin with an overview of leamer s 1983 critique and his proposed remedies we then turn to the key factors we see contributing to improved empirical work including the availability of more and better data along with advances in theoretical econometric understanding but especially the fact that research design has moved front and center in much of empirical micro we offer a brief digression into macroeconomics and industrial organization where progress by our lights is less dramatic although there is work in both fields that we find encouraging finally we discuss the view that the design pendulum has swung too far critics of design driven studies argue that in pursuit of clean and credible research designs researchers seek good answers instead of good questions we briefly respond to this concern which worries us little

efficient supply contracts for fashion goods with forecast updating and two production modes we examine the problem of developing supply contracts that encourage proper coordination of forecast information and production decisions between a manufacturer and distributor of high fashion seasonal products operating in a two mode production environment the first production mode is relatively cheap but requires a long lead time while the second is expensive but offers quick turnaround we focus on contracts of the form w1 w2 b wherewi is the wholesale price offered for production modei andb is a return price offered for items left over at the end of the season we find that such a contract can coordinate the manufacturer and distributor to act in the best interest of the channel the pricing conditions needed to ensure an efficient solution vary depending on the degree of demand forecast improvement between periods and the manufacturer s access to forecast information we also examine whether these conditions ensure a pareto optimal solution with respect to two traditional production settings

a comparison of public policies for lead recycling policies that encourage recycling may be used to reduce environmental costs from waste disposal because direct restrictions on disposal are difficult to enforce four recycling policies have been advanced i taxes on the use of virgin materials ii deposit refund programs iii subsidies to recycled material production and iv recycled content standards in this article i analyze the structure of these policies and their cost effectiveness in achieving reductions in disposal i then examine the policies in the empirical context of the recycling of lead from automobile batteries in order to calculate the effects of recycling programs i estimate the elasticities for primary and secondary lead supply and demand my results suggest that price based policy mechanisms can be successful in increasing lead recovery and that the difference in efficiency between the four approaches is similar

scale externalities in korea this paper estimates the nature and magnitude of scale externalities in a developing country korea in the period 1983 1993 this is a period of rapid industry deconcentration from seoul to other metro areas providing a context where externalities are measured when local scale magnitudes are changing dramatically the data allow us to examine the emerging degree of national industrial concentration in different industries as related to their scale externality magnitudes we also examine whether individual industries agglomerate in cities which have a comparative advantage for that industry

input measurement and productivity growth in japanese and u s manufacturing in their article in this review j r norsworthy and david h malmquist 1983 have presented interesting comparisons of productivity growth in the japanese and u s manufacturing sectors their paper starts with the discussion of whether the conventional value added or gnp measurement of output is an appropriate framework for productivity analysis some confusion frequently arises as to whether a production function should be structured on the basis of gross output or value added output separability is a pivotal concept in the analysis of production structures especially in relation to the existence of a real value added aggregate it is well known that there are two types of separability which pertain to the existence of a real value added function weak local separability and strong partial separability the practical advantage of distinguishing these two different forms of separability is that the double deflation method in conventional gnp accounting is justified only when strong partial separability holds using the approximate separability tests of michael denny and melvyn fuss 1977 norsworthy and malmquist have shown that a value added aggregate does not exist in either u s or japanese manufacturing and they conclude that the appropriate output measure for joint investigation of both countries for purposes of productivity analysis is gross output p 953 the purpose of this comment is to indicate some deficiencies in norsworthy and malmquist s analysis in particular it will be demonstrated that the conditions for weak local and strong partial separability in norsworthy and malmquist s paper are incorrectly formulated and as a consequence their findings may not be used as conclusive evidence that a gross output measure is an appropriate basis for the analysis of capital labor substitutability and productivity growth in japan and the united states

supplier selection order allocation a two stage multiple criteria dynamic programming approach this paper proposes a two stage multiple criteria dynamic programming approach for two of the most critical tasks in supply chain management namely supplier selection and order allocation in the first stage to address multiple decision criteria in supplier ranking the analytic hierarchy process ahp is employed in the second stage supplier ranks are fed into an order allocation model that aims at maximizing a utility function for the firm as well as minimizing the total supply chain costs subject to constraints on demand capacity and inventory levels a dynamic programming approach is crafted to solve the proposed bi objective model

analyzing structure of two echelon closed loop supply chain for pricing quality and recycling management abstract this paper analyzes the effects of recycling and product quality level on pricing decision in a two echelon closed loop supply chain clsc where demand is sensitive with price and quality level of the product under stackelberg game setting this paper considers three possible collection activities of used product for recycling viz retailer led collection manufacturer led collection and third party led collection it is found that third party s involvement in used product collection activity is always disadvantageous in this proposed model cost parameters of the reverse channel play an important role in determining best channel structure quality level and price of the product directly vary with recycling a threshold of collection effort determines which party between manufacturer and retailer can provide the best quality product at least price to resolve channel conflict and to distribute surplus profit the concepts of sub game perfect equilibrium and alternative offer bargaining strategy are used the analysis reveals that the subgame perfect equilibrium retail price cuts out channel conflict and depicts particular profit split irrespective of the offering party the proposed model is also justified by illustrating numerical examples

trade offs in designing markets with multiple objectives abstract this paper explores some of the problems involved in designing markets with multiple objectives the first part of the paper considers the issue of how such markets are designed in theory while the second part reviews some evidence on actual applications in the field of air pollution control

what s to know about the credibility of empirical economics the scientific credibility of economics is itself a scientific question that can be addressed with both theoretical speculations and empirical data in this review we examine the major parameters that are expected to affect the credibility of empirical economics sample size magnitude of pursued effects number and pre selection of tested relationships flexibility and lack of standardization in designs definitions outcomes and analyses financial and other interests and prejudices and the multiplicity and fragmentation of efforts we summarize and discuss the empirical evidence on the lack of a robust reproducibility culture in economics and business research the prevalence of potential publication and other selective reporting biases and other failures and biases in the market of scientific information overall the credibility of the economics literature is likely to be modest or even low

revenue sharing coordination in reverse logistics a reverse supply chain as a post consumption activity aims at extracting value from products at the end of their life cycle it could be comprised of reusing refurbishing remanufacturing and recycling activities in this paper we revisit the issue of revenue sharing in reverse supply chains to formulate the decision problems of coordinating parties manufacturer and retailer the coordination is formed in a dynamic setting where a feedback relationship exists between the return incentive policy of the retailer and the revenue sharing incentive strategy of the manufacturer to model this process we have adopted the use of a system dynamics sd approach sd is well suited for studying the behavior of complex systems over time and where internal feedbacks and delays exist we first identify pareto optimal solutions for individual players and from environmental perspectives of landfill diversion and carbon offset we then focus on revenue sharing as a widely practiced coordination scheme in reverse supply chains it resembles a leader follower stackelberg strategic decision making game with an equilibrium solution that yields lower performance for environmental criteria in this context we investigate if how a revenue sharing mechanism can be coordinated to achieve a higher environmental performance

green consumption under misperceived prices an application to active transportation we propose a consumption model that captures the impact that perceived price ambiguities may have upon decision making in green markets in general and in active transportation markets in particular the basic intuition for the model is that a consumer who may be misperceiving the price of the green good the active transportation mode would be willing to pay a positive amount from her income in the current period to resolve the misperception going forward we posit that the basis for the price misperception in the active transportation context is misperception of the relative risks involved in taking that mode the compensating variation that aligns perceived and objective risk is derived we show how raising green consumption via price misperception correction can be superior to traditional economic policy instruments the results shed light on the more general family of situations in which agents may consistently misperceive aspects of the decision environment

curbside recycling in the presence of alternatives we measure the extent to which curbside access affects quantity recycled we use novel data to distinguish between new recycling and material diverted from other recycling modes we find that the marginal impact of expanding curbside programs on total recycled quantities is small in part because curbside programs significantly cannibalize returns from drop off recycling centers failure to account for cannibalization from other modes may substantially over estimate the benefits of curbside programs we conclude with simple cost effectiveness comparisons results suggest that incremental expansion of curbside access may not be cost effective

the roles of stakeholder support and procedure oriented management on asset recovery abstract as the management of returned products is fast becoming a business trend caused by pressure for compliance asset recovery is increasingly viewed as a fertile area for firms to reduce cost and improve quality environmental management is a viable approach for chinese manufacturers to respond to the escalating international quest for conserving the environment to tackle the problem of rising raw material costs and to improve product quality by analyzing returned products to reach the goals of cost reduction and product quality improvement manufacturers need to understand how asset recovery can be leveraged through procedure based practices and stakeholder support to enhance performance product type characterized by different levels of demand uncertainty and time to market may affect the outcomes of asset recovery adoption and should also be taken into account drawing on the environmental management and business logistics literature we provide empirical insights on asset recovery adoption using survey data collected from export oriented chinese manufacturers we find that asset recovery and stakeholder support are complementary in strengthening manufacturers financial performance regardless of product type in addition the performance impact of asset recovery can be substantial when manufacturers environmental management practices are less procedural allowing flexibility in the logistics management of product flows

a supplier s optimal quantity discount policy under asymmetric information in the supply chain literature an increasing body of work studies how suppliers can use incentive schemes such as quantity discounts to influence buyers ordering behaviour thus reducing the supplier s and the total supply chain s costs various functional forms for such incentive schemes have been proposed but a critical assumption always made is that the supplier has full information about the buyer s cost structure we derive the optimal quantity discount policy under asymmetric information and compare it to the situation where the supplier has full information

industrial bases and city sizes away from heavy manufacturing and bluecollar occupations and towards professional activities communications finance insurance real estate and high tech activities should we expect these gains and losses to be spread across cities or are certain cities likely to be gainers and others losers in terms of population are losers likely to experience permanent declines in population or for some will their losses level off or will they rebound if the growth industries of an economy operate best in larger cities while declining industries tend to reside in smaller cities this implies national population will shift from smaller cities to locating in larger cities this increase in urban concentration means there will be changes in other patterns of resource usage efficient levels of per capita resources devoted to urban infrastructure roads sewers parks etc tend to rise with city size and it is a common perception that the magnitudes of certain consumer externalities congestion air and water pollution crime etc rise with city size this has implications for public policies governing the allocation of public investment and governing the regulation of externalities moreover the changes in population allocation between larger and smaller cities itself involves to some extend a painful process of population upheavals and there may be public policies which can alleviate the costs of the adjustment process in this paper i outline a conceptual framework and empirical methodologies from which some of these issues can be examined

greenhouse gas emissions waste and recycling policy abstract this paper examines least cost policies for waste reduction incorporating upstream greenhouse gas externalities associated with the production of consumption goods from various materials in particular we decompose the effect of deposit refund advance disposal fees and recycling subsidies on upstream greenhouse gas emissions we find that the benefits of reducing greenhouse gas emissions are of the same order as or larger than the benefits of reducing solid waste disposal implying larger optimal total waste reduction than previous studies furthermore the least cost intervention levels will be material specific and vary substantially across materials finally despite the reductions in emissions implied by increased recycling rates direct recycling subsidies are more costly and generate less emissions reductions than a deposit refund or advance disposal fee

channel coordination when retailers compete this paper explores channel coordination by a manufacturer that sells through competing retailers and that treats these retailers equally as required by the robinson patman act the authors show that in general there exists no single two part tariff with a constant per unit charge that will duplicate the behavioral results i e prices quantities and channel profits that are obtained by a vertically integrated system that is the channel cannot be coordinated except in the trivial cases of identical or noncompeting retailers however an appropriately specified quantity discount schedule will enable the channel to earn the same profits generated by a vertically integrated system conditions are derived under which a manufacturer will prefer to offer various two part tariffs with constant per unit charges instead of the channel coordinating quantity discount schedule the authors also establish the existence of a menu of two part tariffs that mimics all results of a vertically integrated system however only under stringent conditions will retailers select the appropriate tariff from the menu when these conditions are not satisfied the channel is worse off than in the case of a single second best tariff it is also demonstrated that under a wide range of parametric values the manufacturer will prefer to offer the second best two part tariff rather than a menu of two part tariffs that could maximize channel profits

an industry equilibrium analysis of downstream vertical integration this paper investigates the effect of product substitutability on nash equilibrium distribution structures in a duopoly where each manufacturer distributes its goods through a single exclusive retailer which may be either a franchised outlet or a factory store static linear demand and cost functions are assumed and a number of rules about players expectations of competitors behavior are examined it is found that for most specifications product substitutability does influence the equilibrium distribution structure for low degrees of substitutability each manufacturer will distribute its product through a company store for more highly competitive goods manufacturers will be more likely to use a decentralized distribution system this article was originally published in marketing science volume 2 issue 2 pages 161 191 in 1983

efficient implementation of collective extended producer responsibility legislation extended producer responsibility epr is a policy tool that holds producers financially responsible for the post use collection recycling and disposal of their products many epr implementations are collective a large collection and recycling network crn handles multiple producers products in order to benefit from scale and scope economies the total cost is then allocated to producers based on metrics such as their return shares by weight such weight based proportional allocation mechanisms are criticized in practice for not taking into account the heterogeneity in the costs imposed by different producers products the consequence is cost allocations that impose higher costs on certain producer groups than they can achieve independently this may lead some producers to break away from collective systems resulting in fragmented systems with higher total cost yet cost efficiency is a key legislative and producer concern to address this concern this paper develops cost allocation mechanisms that

designing contracts for a reverse supply chain with strategic recycling behavior of consumers abstract in this paper we propose five typical contracts to coordinate decentralized reverse supply chains with strategic recycling behavior of consumers first a reverse supply chain model with strategic recycling behavior of consumers is developed based on the classical newsvendor problem next after analyzing the wholesale price contract we find that the collection quantity of used products increases with the wholesale price then we develop a two stage price contract and find that under this contract the manufacturer could increase the collection quantity by offering a direct incentive to the collector afterwards using the centralized optimal profit as the benchmark we compare the wholesale price contract with the subsidy contract and the cost pooling contract respectively the results show that the subsidy contract is more beneficial to the manufacturer while the cost pooling contract is helpful to the collector yet both lead to lower transfer prices than the wholesale price contract for reverse supply chains finally we design an indemnity contract and conclude that the collector s maximum performance is achieved only when the transfer price equals to the indemnity the total profit of the reverse supply chain under the indemnity contact is not less than that under the wholesale price contract

urbanisation and regional productivity in korean manufacturing as the first study for korea we estimate the effects of urbanisation and localisation economies on the productivity of 19 korean manufacturing industries in 1983 1988 and 1993 based on the observation that material inputs contributed about 60 per cent of productivity growth in korea we consider gross output productivity which is an innovation that distinguishes our study from previous ones we find that localisation economies have been dominant features of korean manufacturing industries whereas korean manufacturing industries did not benefit much from locating in large cities more interestingly there are some indications of quadratic relations between city size and urbanisation economies

shared savings contracts for indirect materials in supply chains channel profits and environmental impacts there are many materials for which the quantity needed by a firm is at best indirectly related to the quantity of final product produced by that firm such as solvents in manufacturing processes or office supplies for any such indirect materials an inescapable incentive conflict exists the buyer wishes to minimize consumption of these indirect materials while the supplier s profits depend on increasing volume both buyer and supplier can exert effort to reduce consumption hence making the overall supply chain more efficient however no supplier will voluntarily participate unless contract terms are fundamentally revised this can be done through a variety of shared savings contracts where both parties profit from a consumption reduction this paper analyzes several such contracts currently in use for chemicals purchasing we show that such contracts can always increase supply chain profits but need not lead to reduced consumption we analyze equilibrium effort levels consumption and total profits and show how these change with the contract parameters we find that the goals of maximizing joint profits and minimizing consumption are generally not aligned also surprisingly a decrease in a cost parameter can lead to a decrease in profits it may be necessary but is always possible to renegotiate the shared savings contract to reap the benefits of a cost decrease

a game theory framework for cooperative management of refillable and disposable bottle lifecycles abstract firms engaged in industrial ecology hope to reduce environmental impacts and costs improve resource efficiency and create symbiotic relationships that reduce transaction costs and enhance information flow however current lca tools do not explain firms incentives to implement the principles of industrial ecology or how an individual or firm can affect the products and processes at other firms game theory on the other hand allows investigation of the willingness of producers and consumers to seek strategies that promote the common interest of the system while not harming their own interests this paper applies game theory to the lifecycle of bottle packaging and presents a framework for analysis of the choice between refillable and disposable bottles although refillable bottles may be more cost effective in the long run bottlers only have incentive to use refillable bottles when they are sure that consumer return rates will be reasonably high it has been found that consumers who keep or dispose of refillable bottles or respond to deposit refund return incentives by reducing their demand may drive costs up and encourage adoption of disposables a simple model is provided which finds the optimal bottler strategy as a function of the bottler s expectations for consumer cooperation

vertical strategic interaction implications for channel pricing strategy this paper examines two strategic pricing decisions within channels using foresight i e price leadership and considering category implications i e product line pricing are price leadership and product line pricing always the best pricing strategies for a channel member if not when does this occur and why by investigating these questions we address some major concerns of both marketing practitioners and scholars interested in channel management issues in addition this study provides an indepth discussion on why previous analytic studies produced answers to these questions that depend upon the choice of the form of demand functions as such this study should significantly resolve the debate among analytic marketing modelers about the right demand specification at the core of our discussion lies the concept of vertical strategic interaction which is defined in terms of the direction of a channel member s reaction to the actions of its channel partner within a given demand structure specifically if a channel member s best reaction is to reduce its margin when its channel partner increases its margin the type of vertical strategic interaction is referred to as vertical strategic substitutability vss if the best reaction is to increase the margin the environment is referred to as vertical strategic complementarity vsc if the best reaction is no margin change it is referred to as vertical strategic independence vsi using a game theoretic approach we demonstrate that these three types of vertical strategic interactions represent a key driving force for optimal decisions on channel price leadership and product line pricing our investigation involves mathematical analyses of an industry model composed of two manufacturers selling competing products both carried by two competing retailers as such the model allows for retailer product line pricing as well as manufacturer and retailer level competition in addition this general model can be used to analyze three more restrictive industry settings often found in the channels literature i e a bilateral monopoly jeuland and shugan jeuland abel steven m shugan 1983 managing channel profits marketing sci 2summer 239 72 two competing manufacturers selling through competing franchised retailers mcguire and staelin mcguire timothy w richard staelin 1983 an industry equilibrium analysis of downstream vertical integration marketing sci 2spring 161 92 and two competing manufacturers selling through one common retailer using product line pricing choi choi s chan 1991 price competition in a channel structure with a common retailer marketing sci 10fall 271 96 unlike many other channel studies most of our analyses are performed without assuming particular functional forms of demand curves thus this paper provides greater assurance that the insights from this stream of research are broadly applicable not only across industry structures but also across demand conditions the paper starts out by defining three different rules for how prices are set the manufacturer uses foresight the retailer uses foresight and neither channel member uses foresight we then show a one to one mapping between the type of vertical strategic interaction and the optimality of channel price leadership specifically a channel member finds it profitable to be a price leader for vss but prefers to be a follower for vsc for vsi channel members are indifferent to the channel price leadership issue as it has no effect on channel member profits we also show that there exist conditions under which a retailer might see a reduction in profits when it changes its policy from non product line pricing to product line pricing such conditions arise when the retailer is not a price leader and the environment is characterized by vss or vsc at a more general level this study suggests not only the value but also the cost to a firm for using superior knowledge i e foresight and or product line pricing in making strategic marketing decisions in this way ignorance can be bliss we also explore the link between demand characteristics and the three types of vertical strategic interaction we show that the type of vertical strategic interaction present in a given environment is closely related with the convexity of the demand curve and the level of demand for a given price interestingly we find that linearity of demand is not a necessary condition for any of the three types of vertical strategic demand function consequently in evaluating the robustness of analytic analyses it may be more important to determine the type of vertical strategic interaction assumed instead of whether the demand is linear or nonlinear finally our results are limited to situations where the channels are not coordinated and the retailer s precommitment to particular pricing policy and decision is credible although such situations still capture a significant portion of reality we acknowledge that the insights from this study might not be applicable in all situations

optimal policies for solid waste disposal taxes subsidies and standards abstract pricing trash collection and disposal services can be politically unpopular and may lead to increased illegal disposal of trash several studies have shown that deposit refund systems can act like disposal charges without the illegal disposal problem and thus can generate an optimal amount of solid waste disposal we assess the efficiency implications of an alternative policy currently in use in some states in the u s and considered at the federal level recycled content standards these are requirements that a certain fraction of total material use in production be comprised of secondary materials we find that such standards by themselves cannot generate the optimal amount of disposal but must be combined with additional taxes on both the final product and other inputs to production moreover the information requirements for setting the optimal standards and accompanying taxes are high the deposit refund approach would be preferred in most cases

productive efficiency and region based on estimates of cobb douglas production function this study has found that significant spatial variation in labor productivity exists even after adjusting for capital intensity the adjustment for capital intensity reduces the regional variation by 38 to 69 and the ciy size variation by 75 the results reveal a 6 to 8 producitivity advantage for non south census regions relative to the south and productivity increases of 1 5 with each doubling of smsa population nevertheless lower wages in the south and in smaller cities make it and them an attractive location for manufacturing firms the study has also found that the sveikauskas conjecture that labor productivity can be substituted for hicks neutral productivity in an analysis of the latter is false if metropolitan data are used by so doing capital intensity effects and total factor productivity effects are confounded to study spatial variations in total factor productivity productive efficiency it is necessary to control for spatial variations in captial intensity the results of this study indicate that absent better data on capital the approach offered by aberg yields satisfactory results 14 references 2 tables

modeling of biomass to energy supply chain operations applications challenges and research directions reducing dependency on fossil fuels and mitigating their environmental impacts are among the most promising aspects of utilizing renewable energy sources the availability of various biomass resources has made it an appealing source of renewable energy given the variability of supply and sources of biomass supply chains play an important role in the efficient provisioning of biomass resources for energy production this paper provides a comprehensive review and classification of the excising literature in modeling of biomass supply chain operations while linking them to the wider strategic challenges and issues with the design planning and management of biomass supply chains on that basis we will present an analysis of the existing gaps and the potential future directions for research in modeling of biomass supply chain operations

agglomeration economies in urban manufacturing industries a case of japanese cities abstract the effects of urban agglomeration economies on productivities in two digit manufacturing industries is estimated using the cross section data of japanese cities in 1979 urbanization and localization economies which are major forms of urban agglomeration economies are explicitly separated the estimates of these economies vary considerably among industries light industries receive more productive advantages from urbanization economies than from localization economies but heavy industries experience these economies more from localization economies than from urbanization economies

process innovation product differentiation and channel structure strategic incentives in a duopoly in this paper we analyze the joint implications of two effects a inserting independent profit maximizing retailers into thechannel system provides buffering to the manufacturers from price competition when their products are highly substitutable and intrachannel contracts are observable as shown by mcguire and staelin 1983 under the assumption of constant marginal production costs and b lack of channel coordination results in a reduction in manufacturer s incentives to invest in efforts to reduce production costs as shown by jeuland and shugan 1983 for the case of bilateral monopoly we show that both these results are robust in the sense that the first holds even in the presence of the vertical externality of manufacturer s effort reduction in a noncoordinated channel and the second holds regardless of the degree of substitutability between the competing channel s products specifically we analyze a four stage game with two manufacturers and two retailers where the intrachannel contracts are linear and observable and manufacturers make investments in process improvements to reduce their production costs we find that the optimal channel structure decision depends on interactions between two parameters the degree of substitutability between products and the level of investments required to achieve production cost reduction these parameters represent what have been widely interpreted in the management literature as the two primary generic strategies that most organizations follow in order to gain competitive advantage cost leadership and product differentiation porter 1980 thus our analysis brings out the strategic and interdisciplinary nature of the channel structure decision that can significantly affect firm profitability our main results are as follows first we find that decentralized noncoordinated channels appear as more profitable equilibrium than integration or perfectly coordinated channels at high product substitutability even when process innovation dimension is accounted for in agreement with the literature however the range of substitutability over which decentralization is an equilibrium strategy is smaller the easier it is to reduce production costs intuitively the easier the cost reduction the larger the cost penalty that the channel incurs as a result of not coordinating investment and pricing decisions between channel members and thus smaller the range over which decentralization is an equilibrium this implies that there is an explicit tradeoff between efficiency and strategic incentives in distribution channel design second we show that decentralized manufacturers invest less in process innovation than integrated manufacturers do regardless of the structure of the competing channel and the degree of substitutability between products consequently a decentralized channel has higher costs charges higher prices and produces lower quantities than an integrated channel does moreover these differences get larger the easier the cost reduction the effect on manufacturer profits however is not that clear manufacturers make higher profits by decentralizing if products are highly substitutable inagreement with mcguire and staelin 1983 and coughlan and wernerfelt 1989 however we also find that the relative profitability of decentralization at high substitutability and of integration at low substitutability increases the easier the cost reduction moreover the range of substitutability over which decentralization is more profitable than integration is itself larger the easier the cost reduction though decentralization is an equilibrium strategy over a smallerrange thus process innovation accentuates the profit difference between integrated and decentralized channels andmakes the prisoner s dilemma situation worse in the choice of distribution channel structure finally we analyze two examples of coordinated decision making in a channel a divisional integrated system and franchising in the first case we find that decentralization can emerge as a unique and more profitable equilibrium at high product substitutability in contrast to mcguire and staelin 1983 in the second case we find that decentralization is not always a unique equilibrium and it is not always more profitable than integration in sharp contrast to the results by coughlan and wernerfelt 1989 thus franchising does not provide a sure way of achieving channel coordination when marginal production costs are not constant in sum this paper highlights the importance of simultaneously considering both the horizontal and the vertical dimensions of interorganizational relations on one hand and on the other paying attention to cross functional interactions across marketing and operational decisions to better understand the underlying incentives that shape firm and market structures conventional focus of marketing on demand side effects and of operations on cost side effects can lead to suboptimal decisions

note the role of returns policies in pricing and inventory decisions for catalogue goods manufacturers often use returns policies to encourage retailers to stock and price items more aggressively we focus on the effect that such policies have on both a retailer s and a manufacturer s profits when the retailer must commit prior to the selling season to both a stocking quantity and a price at which to sell an item such a commitment is often necessary for retailers who sell primarily through catalogues

the two part instrument in a second best world abstract standard pigovian tax theory has been extended in two directions first many polluting activities are difficult to tax because they are not market transactions and so recent papers have shown that the same effects can be achieved by use of a two part instrument 2pi a tax on output or income and a subsidy for clean alternatives to pollution it is a generalization of a deposit refund system drs second a different literature concerns the second best pollution tax in the presence of other tax distortions here we combine the two extensions by looking at the second best 2pi when government needs revenue is the deposit larger and the rebate smaller we find explicit solutions for each tax and subsidy in a general equilibrium model with other tax distortions and we compare these to the rates in a first best model the tax subsidy combination is explained in terms of a tax effect an environmental effect and a revenue effect the model allows for flexible interpretation to show various applications of the 2pi we also discuss important caveats

an exploratory game theoretic analysis of biomass electricity generation supply chain this study proposes a game theoretic approach to model and analyze the process of utilizing biomass for power generation considering three players distributor facility developer and participating farmer we characterize the nash equilibrium of the sequential game and discuss its features a special attention is devoted to the analysis of the impact of incentives and initial target on the equilibrium in which the biomass is part of electricity production

impact of government financial intervention on competition among green supply chains abstract this work analyzes the effects of governmental financial intervention on green supply chain competition using a three stage game theoretic model nash equilibrium solutions for governmental and chain member decisions are derived analytical results suggest that the government should adopt green taxation and subsidization to ensure that green profit attributed to green product production is non negative strategically low wholesale price strategies are suggested to recycled component suppliers under green subsidization to stimulate manufacturers intention of green product production under green taxation numerical results reveal that under equilibrium conditions social welfare and chain based profits improve by 27 8 and 306 6 respectively compared with the case without financial intervention

feed in subsidies taxation and inefficient entry we study energy markets with dirty production and lumpy entry costs of clean production renewables for intermediate entry costs markets yield inefficient production and inefficient entry a mix of three popular regulatory instruments polluter taxation feed in subsidies for renewables and consumption taxation cannot correct these market failures for larger entry costs the instruments are imperfect because they affect marginal incentives whereas entry is a lumpy fixed cost problem whenever the first best is implementable feed in subsidies and consumption taxes are redundant the second best requires feed in subsidies or consumption taxes in addition to a pollution tax and overshoots first best levels given production levels the instruments do not affect the regulator s budget

firm location and city size reduced productivity advantages as a factor in the decline of manufacturing in urban areas abstract this paper develops a model of firm location and city size that arrives at theoretical conclusions that differ from those of other authors comparative statics results suggest that changes in national wage levels and productivity levels create no determinate dis advantage for large cities relative to small ones as sites for manufacturing activity increased wage and reduced productivity premiums of large cities however result in unambiguous disadvantages statistical analysis indicates that the productivity advantages of large cities have declined in as many as eight two digit manufacturing industries that provide more than one third of metropolitan production worker employment

factors influencing willingness to accept different waste management policies empirical evidence from the european union abstract improving waste management strategies with more collaborative participation and responsibility of different public and private agents is a matter of increasing concern for academia and policy makers based on data from 28 european countries the present study unlike other previous studies analyzing the influence of individual drivers for waste generation or recycling evaluates different options for waste management government based fair consumer and producer responsibility for this the influence of individual and socio demographic characteristics age gender education level and occupational status contextual variables rural or urban country of origin and the environmental awareness of 23 976 individuals are considered being a woman being well educated having a good job and living in a rural or small town increase the probability of being a fair consumer while men and people living in a large town are more willing to entrust this responsibility to firms the government based solution is only chosen by low educated people finally individuals with the highest environmental awareness and effort prefer to pay while those who are less environmentally conscious prefer government action the findings show that factors explaining individual acceptance of these different waste management policies wmp are essential for implementing proactive and preventive approaches to enhance responsibility and involvement of all stakeholder groups consumers firms and institutions

manufacturer s revenue sharing contract and retail competition this paper investigates a revenue sharing contract for coordinating a supply chain comprising one manufacturer and two competing retailers the manufacturer as a stackelberg leader offers a revenue sharing contract to two competing retailers who face stochastic demand before the selling season under the offered contract terms the competing retailers are to determine the quantities to be ordered from the manufacturer prior to the season and the retail price at which to sell the items during the season the process of pricing and ordering is expected to result in an equilibrium as in the bayesian nash game on the basis of anticipated responses and actions of the retailers the manufacturer designs the revenue sharing contract adopting the classic newsvendor problem model framework and using numerical methods the study finds that the provision of revenue sharing in the contract can obtain better performance than a price only contract however the benefits earned under the revenue sharing contract by different supply chain partners differ because of the impact of demand variability and price sensitivity factors the paper also analyses the impact of demand variability on decisions about optimal retail price order quantity and profit sharing between the manufacturer and the retailers lastly it investigates how the competition between retailers factor influences the decision making of supply chain members in response to uncertain demand and profit variability
