operating flexibility global manufacturing and the option value of a multinational network the multinational corporation is a network of activities located in different countries the value of this network derives from the opportunity to benefit from uncertainty through the coordination of subsidiaries which are geographically dispersed we model this coordination as the operating flexibility to shift production between two manufacturing plants located in different countries a stochastic dynamic programming model treats explicitly this flexibility as equivalent to owning an option the value of which is dependent upon the real exchange rate the model is extended to analyze hysteresis effects and within country growth options we show that the management of across border coordination has led to changes in the heuristic rules used for performance evaluation and transfer pricing

on the integration of production and financial hedging decisions in global markets we study the integrated operational and financial hedging decisions faced by a global firm who sells to both home and foreign markets production occurs either at a single facility located in one of the markets or at two facilities one in each market the company has to invest in capacity before the selling season starts when the demand in both markets and the currency exchange rate are uncertain the currency exchange rate risk can be hedged by delaying allocation of the capacity to specific markets until both the currency and demand uncertainties are resolved and or by buying financial option contracts on the currency exchange rate when capacity commitment is made a mean variance utility function is used to model the firm s risk aversion in decision making we derive the joint optimal capacity and financial option decision and analyze the impact of the delayed allocation option and the financial options on capacity commitment and the firm s performance we show that the firm s financial hedging strategy ties closely to and can have both quantitative and qualitative impact on the firm s operational strategy the use or lack of use of financial hedges can go beyond affecting the magnitude of capacity levels by altering global supply chain structural choices such as the desired location and number of production facilities to be employed to meet global demand

operational hedging strategies and competitive exposure to exchange rates this paper investigates the impact of operational flexibility on firms economic exposure to currency fluctuations in the presence of global competition we consider a global firm who sells as a monopolist in the domestic market and also sells to a foreign market facing competition from a local competitor of certain capacity we compare the effects of two operational strategies of the global firm namely matching currency footprints natural hedge and the capacity pooling strategy with allocation flexibility for a two stage stochastic model we derive the optimal capacity and selling decisions for the global firm and from the comparative statics analysis of our model we infer useful managerial insights 1 we find that operational flexibility enables the global firm to exploit the possible high exchange rate i e devalued home currency realizations for profit improvement and thus increases in the long run the firm s expected profit 2 furthermore operational flexibility allows for downside risk control as the exchange rate becomes more volatile since the resource pooling option cleverly exercised minimizes the impact of unfavorable currency realizations 3 the global firm s operational flexibility increases its competitor s downside risk but may also benefit the competitor s expected profit since a flexible global firm may decide not to compete when the exchange rate is not favorable in conclusion our paper substantiates that natural hedge is not effective from a profit maximization perspective we clearly illustrate the robust profit maximizing performance and reasonable downside risk control of operational hedging approaches which rely on the clever exercising of operational flexibility options such as resource pooling and allocation in handling competitive exposure to fluctuating exchange rates

environmental kuznets curve hypothesis in pakistan cointegration and granger causality abstract the paper is an effort to fill the gap in the energy literature with a comprehensive country study of pakistan we investigate the relationship between co2 emissions energy consumption economic growth and trade openness in pakistan over the period of 1971 2009 bounds test for cointegration and granger causality approach are employed for the empirical analysis the result suggests that there exists a long run relationship among the variables and the environmental kuznets curve ekc hypothesis is supported the significant existence of ekc shows the country s effort to condense co2 emissions and indicates certain achievement of controlling environmental degradation in pakistan furthermore we find a one way causal relationship running from economic growth to co2 emissions energy consumption increases co2 emissions both in the short and long runs trade openness reduces co2 emissions in the long run but it is insignificant in the short run in addition the change of co2 emissions from short run to the long span of time is corrected by about 10 yearly

the impacts of transport energy consumption foreign direct investment and income on co2 emissions in asean 5 economies abstract in this study we incorporate new variables and assess the impact of transportation sector s energy consumption and foreign direct investment on co2 emissions for asean 5 economies using the cointegration and granger causality methods this study also attempts to validate the environmental kuznets curve ekc hypothesis our results reveal that the co2 emissions and their determinants are co integrated only in indonesia malaysia and thailand the long run elasticity estimation suggests that income and transport energy consumption significantly influence co2 emissions whereas fdi is not significant economic growth plays a greater role in contributing to co2 emission in asean 5 nonetheless we find that the inverted u shape ekc hypothesis is not applicable to the asean 5 economies especially in indonesia malaysia and thailand in the long run the bi directional causality between economic growth and co2 emissions is detected in indonesia and thailand while we find unidirectional causality running from gdp to co2 emissions in malaysia we also observe bi directional causality between transport energy consumption fdi and co2 emissions in thailand and malaysia as an immediate policy option controlling energy consumption in transportation sector may result in a significant reduction in co2 emissions however this may slow the process of economic growth in malaysia and indonesia alternatively we suggest policymakers to place more emphasis on energy efficient transportation system and policies to minimise fossil fuel consumption thus the quality of environment can be improved with less deleterious impact on economic growth

supply contracts profit sharing switching and reaction options a common theme in the studies of flexible supply contracts has been the producer s profit maximization problem without regard to the suppliers reactions however suppliers do react and protect their downside against producer s operating policies by revising their strategies in a manner consistent with their profitmaximization objectives this fact motivates our work using a real options contingent claims approach we analyze and value supply contracts in a setting characterized by exchange rate uncertainty supplier switching options order quantity flexibility profit sharing and supplier reaction options we also use basic diversification concepts from portfolio theory to analyze risk reduction in a unique framework given this setup we explicitly model how flexibility can be mutually beneficial to both the producer and the suppliers using this model we concurrently solve and examine the dual optimization problem for the suppliers and the producer our approach also endogenizes the extent and degree of profit sharing through the resulting optimal policies we also analyze what induces the producer and the suppliers to accept flexibility in their contracts

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

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

manufacturers and retailers in the global economy we develop a general equilibrium model to capture key features of the retailing and of the manufacturing industry in order to understand how these two industries interact and how labor is allocated between them we show that the observed shift in employment from manufacturing to retailing the rise in retailer product assortment and the emergence of slotting allowances in many retail markets are consistent with the global integration of product markets while higher retail market concentration is best explained by technological change in retailing we also identify a novel benefit from market integration consisting of efficiency gains in the vertical distribution chain

estimating the environment kuznets curve hypothesis evidence from latin america and the caribbean countries this study explores the effect of economic growth gdp renewable energy consumption re and financial development fd on co2 emission co2 in latin america and caribbean countries to achieve this goal a panel co2 model was built over the period 1980 2010 the kao cointegration test results revealed that the variables are cointegrated the fully modified ols fmols results indicated an inverted u shape relationship between co2 and gdp thus confirming the environmental kuznets curve hypothesis furthermore fmols results also revealed that fd can improve environmental quality by its negative long run effect on co2 however re has no long run effect on co2 indicating that the re does not contribute to co2 reduction the vecm granger causality results revealed feedback causality between gdp re fd and co2 in both short and long run additionally granger causality results also revealed that re gdp and fd can be a good solution to reduce environmental damage since they have a causal effect on co2 this study shows the investigated countries should increase their banking loans on green energy energy efficiency and energy saving projects to reduce environmental damage in addition the above recommendation can increase the contribution of renewable energy in reducing environmental damage

outsourcing and capacity planning in an uncertain global environment firms employing offshore outsourcing strategies may face both exchange rate and demand uncertainties in this paper we show that the firms may benefit from operational option to switch production by keeping capacities with both domestic and foreign suppliers the value of the operational option increases as the exchange rate uncertainty or demand uncertainty increases in addition when the firms become risk averse they may use domestic capacity to hedge against offshore capacity as a result the firms may choose to hold local capacity even if it exhibits negative marginal contribution to the profit furthermore risk averse firms may keep more total capacity than risk neutral firms

global production planning under exchange rate uncertainty motivated by an aggregate production planning problem in an actual global manufacturing network we examine the impact of exchange rate uncertainty on the choice of optimal production policies when the allocation decision can be deferred until the realization of exchange rates this leads to the formulation of the problem as a two stage recourse program whose optimal policy structure features two forms of flexibility denoted as operational hedging 1 production hedging where the firm deliberately produces less than the total demand and 2 allocation hedging where due to unfavorable exchange rates some markets are not served despite having unused production our characterization of the optimal policy structure leads to an economic valuation of production and allocation hedging we show that the prevalence of production hedging is moderated by the degree of correlation between exchange rates a comprehensive examination under the following four generalized settings provides the depth scope and relevancy that our proposed operational hedges play to facilitate aggregate planning 1 multiple periods 2 demand uncertainty 3 price setting or monopolistic pricing and 4 price setting under demand uncertainty we show that production and allocation hedging are robust for these generalizations and should be integrated into the overall aggregate planning strategy of a global manufacturing firm

integrated operational and financial hedging with capacity reshoring abstract we consider a multinational corporation that employs capacity reshoring production switching and financial hedging to manage supply demand mismatches and currency risk we optimize mean conditional value at risk cvar by decomposing operations and finance operational flexibility maximizes expected profit subject to a cvar constraint whereas financial hedging minimizes cvar subject to a minimum expected profit we report three main findings first operational flexibility and financial hedging can be complements operational flexibility enhances profitability and reduces downside risk while financial hedging minimizes downside risk and can affect the feasible set of capacity portfolios albeit indirectly by relaxing a cvar constraint second operational flexibility and financial hedging are substitutes in risk reduction though the latter has greater risk reduction effects in cvar when used alone third coordinating operations and finance is crucial for minimizing substitution effects efficient financial hedging depends on rigorous estimation of cash flow distribution as shaped by operational flexibility and a capacity portfolio s feasibility relies on financial hedging because of the cvar constraint

screening location strategies to reduce exchange rate risk abstract a firm that markets its products and services world wide may face significant financial risk due to exchange rate fluctuations unless it maintains an international sourcing production network thus the firm must evaluate various sourcing production network designs the selection of the appropriate design is not straight forward since decisions are made in an environment of uncertainty and involve multiple time periods we propose a two phase approach to screen various alternative designs configurations utilizing a number of criteria and illustrate it using a popular harvard business school case as by products we introduce a new criterion for making a pairwise stochastic comparison of alternatives and demonstrate the value of maintaining excess geographically dispersed production capacity

technical note financial market approaches to facility location under uncertainty this paper examines financial market approaches for facility location models incorporating uncertainty and risk aversion as an example it compares a model based on the capital asset pricing model with one using a mean variance objective function there are dramatically different computational implications the financial market approach yields simpler procedures and is able to handle more complex problems however as discussed in the concluding observations there are situations where the financial market perspective is less appropriate consequently the mean variance model still has a role in analyzing facility location decisions

the newsvendor problem in a global market optimal centralized and decentralized control policies for a two market stochastic inventory system the global markets of today offer to the style goods producer more selling opportunities and pose new challenges in production planning and coordination from a production management standpoint the opportunity to exploit the difference in timing of the selling season of geographically dispersed markets for style goods is important for improving the firm s profitability in this paper we examine the above issue with an insightful model of a producer of style goods selling the goods to two markets a primary and a secondary market with nonoverlapping selling seasons we refer to this problem as the global newsvendor problem for the above two market stochastic inventory systems we first develop optimal centralized control policies then we demonstrate the suboptimality of decentralized production control policies with the production centers at each market treated as independent profit centers and a constant transfer price being used to coordinate their production we propose as an effective alternative a decentralized production control structure with a nonlinear pricing scheme for production coordination among centers administered through an intermediate organizational unit in our modeling we explicitly consider the effects of exchange rate uncertainty on the production planning decisions

timing and eco nomic efficiency of climate friendly investments in supply chains abstract emission trading schemes such as the european union emissions trading system euets attempt to reconcile economic efficiency with ecological efficiency by creating financial incentives for companies to invest in climate friendly innovations using real options methodology we demonstrate that under uncertainty economic and ecological efficiency continue to be mutually exclusive this problem is even worse if a climate friendly project depends on investing in of a whole supply chain we model a sequential bargaining game in a supply chain where the parties negotiate over implementation of a carbon dioxide co2 saving investment project we show that the outcome of their bargaining is not economically efficient and even less ecologically efficient furthermore we show that a supply chain becomes less economically efficient and less ecologically efficient with every additional chain link finally we make recommendations for how managers or politicians can improve the situation and thereby increase economic as well as ecological efficiency and thus also the eco efficiency of supply chains

formation of a strategic manufacturing and distribution network with transfer prices abstract we propose a profit maximization model for the decision support system of a firm that wishes to establish or rationalize a multinational manufacturing and distribution network to produce and deliver finished goods from sources to consumers the model simultaneously evaluates all traditional location factors in a manufacturing and distribution network design problem and sets intra firm transfer prices that take account of tax and exchange rate differentials between countries utilizing the generalized benders decomposition approach we exploit the partition between the product flow and the cash allocation i e the pricing and revenue assignment decisions in the supply chain to find near optimal model solutions our proposed profit maximizing strategic planning model produces intuitive results we offer computational experiments to illustrate the potential valuable guidance the model can provide to a firm s supply chain design strategic planning process

pricing network effects the increase in the information that firms can collect or purchase about network effects across consumers motivates two important questions how does a firm s pricing strategy react to detailed information on network effects are the availability and use of such information beneficial or detrimental to consumer surplus we develop a model in which a monopoly sells a network good and price discriminates based on information about consumers influence and consumers susceptibility to influence the monopoly optimally offers consumers price discounts for their influence and charges price premia for their susceptibility the price premia and the price discounts are simple functions of the pattern of network effects we determine under which conditions relative to uniform price consumer surplus increases and we characterize the value of information on network effects for the monopoly

facts and figures on intermediated trade over the past several years trade economists have begun exploring the role that intermediar ies play in facilitating trade papers by james e rauch and joel watson 2004 dimitra petropoulou 2007 and pol antras and arnaud costinot 2009 model intermediaries as agents that facilitate matching between sellers exporters and foreign buyers these papers examine how improved intermediation matching technolo gies affect trade volumes and the gains from trade bernardo s blum sebastian claro and ignatius horstmann 2009 embed a reduced form match ing model inspired by robert townsend 1983 into a heterogeneous firm trade model and exam ine how changes in the trading environment affect trade costs export import volumes and the extent of trade flowing through trade intermediaries a key modeling challenge for this literature is how to structure matching and intermediation technologies in trading environments blum claro and horstmann 2009 provide certain facts for chile colombia trade and use these facts to structure trading technologies in this paper we provide a broader set of facts on trade intermediaries using new datasets for chile and for chile argentina trade 1 we think that these facts will prove particularly useful for future modeling of trade intermediaries

supply chain network equilibrium with strategic financial hedging using futures abstract in this paper we develop a network equilibrium model for supply chain networks with strategic financial hedging we consider multiple competing firms that purchase multiple materials and parts to manufacture their products the supply chain firms procurement activities are exposed to commodity price risk and exchange rate risk the firms can use futures contracts to hedge the risks our research studies the equilibrium of the entire network where each firm optimizes its own operation and hedging decisions we use variational inequality theory to formulate the equilibrium model and provide qualitative properties we provide analytical results for a special case with duopolistic competition and use simulations to study an oligopolistic case the analytical and simulation studies reveals interesting managerial insights

environment kuznets curve for co2 emissions a cointegration analysis for china abstract this study examines the long run relationship between carbon emissions and energy consumption income and foreign trade in the case of china by employing time series data of 1975 2005 in particular the study aims at testing whether environmental kuznets curve ekc relationship between co 2 emissions and per capita real gdp holds in the long run or not auto regressive distributed lag ardl methodology is employed for empirical analysis a quadratic relationship between income and co 2 emission has been found for the sample period supporting ekc relationship the results of granger causality tests indicate one way causality runs through economic growth to co 2 emissions the results of this study also indicate that the carbon emissions are mainly determined by income and energy consumption in the long run trade has a positive but statistically insignificant impact on co 2 emissions

impact of sourcing flexibility on the outsourcing of services under demand uncertainty abstract this paper investigates the relationship between market conditions and the value and use of sourcing flexibility for service processes we develop and analyze a series of models and we derive expressions for the optimal switching decision the value of the option to outsource the value of the option to backsource and the probability and timing of switches between the alternative sources one contribution is the models and associated derivations which are largely new to the literature and may serve as a tool to support service sourcing plans and decisions the second contribution is a series of results with managerial implications 1 the probability of outsourcing is generally increasing in volatility for high skill process and decreasing in volatility for low skill processes earlier work has found that the hysteresis band is increasing in volatility which is interpreted as an indicator of increasing organizational inertia we also find that the hysteresis band is increasing in volatility but interestingly for the case of high skill processes organizational inertia tends to be decreasing in volatility 2 the option to backsource is generally more valuable for high skill processes than for low skill processes this result suggests that investments to make it easier to backsource should have a higher priority for high skill processes 3 the value of the option to backsource a high skill service process can be decreasing in volatility the result suggests that a rather nuanced consideration of volatility is in order when considering investments in the flexibility to backsource a high skill process

global facility network design in the presence of competition abstract we study the facility network design problem for a global firm that is a monopolist seller in its domestic market but faces local competition in its foreign market the global firm produces in the face of demand and exchange rate uncertainty but can postpone localization and distribution of the output until after uncertainties are resolved the competitor in the foreign market however enjoys the flexibility of postponing all production activities until after uncertainties are resolved the two firms engage in an ex post cournot competition in the foreign market we consider three potential network configurations for the global firm under a linear demand function we provide the necessary and sufficient condition that one of the three networks is the global firm s optimal choice and explore how the presence of foreign competition affects the sensitivity of the global firm s design to various cost parameters and market uncertainties

two sided heterogeneity and exchange rate pass through abstract the bargaining process between exporters and importers is key to understand the degree of exchange rate pass through following the framework established by goldberg and tille 2013 we use a colombian exporter importer matched data from 2005 to 2014 to identify the relative bargaining power between exporters and importers and investigate its effect on exchange rate pass through the results show that within each exporter importer pair the role of importers is at least as important as exporters and higher bargaining power of importers are usually associated with higher exchange rate pass through our findings are robust to a variety of bargaining ability measurement alternative empirical specifications and the selection of certain industries

exchange rates and the choice of ownership structure of production facilities the aim of this research is to study the effects of real exchange rates on the long term ownership strategies of production facilities of firms entering foreign markets among the strategies considered are exporting exp joint ventures with local partners jv and wholly owned production facilities wos in the foreign country our research takes a first step in modeling the influence of exchange rates on the choice and dynamic adjustment of such strategies the insights obtained from our modeling analysis are then translated into testable hypotheses and empirically verified with the use of firm level data from u s multinational corporations both at the firm and a more aggregate level an insightful result of our model is the identification of a hysteresis phenomenon that characterizes switching behavior between strategies in the presence of switchover cost the magnitude of the hysteresis band which is a measure of the inertia associated with keeping the current ownership structure is affected by a multiplicity of factors such as exchange rate volatility and market power of the entering firm analytical and numerical results on the effects of such factors on the hysteresis band are provided the four testable hypotheses generated from our modeling analysis are rigorously tested with the use of a multinomial logit model on data obtained from the harvard multinational enterprise database and a data set maintained by the bureau of economic analysis the u s department of commerce the empirical results strongly support our insights that relatively depreciated real exchange rates i e weak home currency favor a the jv over the wos and b exp mode over the wos or jv finally we summarize our results into useful guidelines for global production managers

a directed search model of intermediated trade abstract this paper complements antras and costinot s 2010 analysis of a two good two country ricardian economy in which farmers produce either goods but require intermediaries to exchange their production in the goods markets the intermediation market is frictional whereas the goods market is perfectly competitive unlike their random search and price bargaining setup intermediaries herein post intermediation prices and farmers direct their search contrary to their findings we show that opening the economy to international trade always leads to welfare gains this is the case because domestic farmers benefit from relatively efficient intermediation technologies in terms of higher matching probabilities but also lower intermediation prices

optimal operating policies in the presence of exchange rate variability we study the structure of the optimal policies for a firm operating plants in different countries the relative costs of production between the plants are assumed to vary over time due to economic and political factors such as exchange rates inflation taxes and tariffs based on the costs the firm can alter the quantity produced in each plant we determine the structure of the optimal policies for deciding when and by how much to alter the production quantities when the switch over costs are linear or step functions regardless of whether the variable production costs are concave or piece wise linear convex and regardless of whether the firm is supplying one or more markets the optimal policy is always a barrier policy the optimal barriers can be determined by using linear programming techniques and the optimal costs can be computed by solving a system of linear equations when the number of optimal barriers is two the optimal expected costs and the condition that determines the optimal barriers are explicitly derived

valuing operational flexibility under exchange rate risk in this paper we develop a stochastic dynamic programming formulation for the valuation of global manufacturing strategy options with switching costs overall we adopt a hierarchical approach first exchange rates are modeled as stochastic diffusion processes that exhibit intercountry correlation second the firm s global manufacturing strategy determines options for alternative product designs as well as supply chain network designs product options introduce international supply flexibility supply chain network options determine the firm s manufacturing flexibility through production capacity and supply chain network linkages third switching costs determine the cost of operational hedging i e the costs associated with reducing downside risks overall the firm maximizes its expected discounted global after tax value through the exercise of product and supply chain network options and or through exploitation of operational flexibility contingent on exchange rate realizations in this environment the firm must trade off fixed operating costs switching costs and the economic benefits derived from exploiting differentials in factor costs and corporate tax rates a multinomial approximation of correlated exchange rate processes is proposed that leads to a consistent and tractable lattice model for this compound option valuation problem we then demonstrate how the global manufacturing strategy planning model framework can be utilized to analyze financial and operational hedging strategies
