%X Residential consumers are increasingly combining renewables with energy storage systems. However, changes in policies and support for these technologies may impact their adoption and the outlook for the energy industry. In this paper, we consider a grid-connected household's problem of determining the optimal capacities of these two technologies as well as the battery operating policy that minimizes its electricity costs when faced with time-of-use electricity prices and sellback credits. We identify the impact of household characteristics, technological progress, and electricity pricing policies on the levels of investment in these two technologies. Furthermore, we supplement our analytical results with a case study of two U.S. cities and identify policy guidelines for the design of a technology subsidy program aimed at stimulating the adoption of these technologies and the ensuing implications for residential customers, the environment, and grid reliability. Our paper has implications for several stakeholders in practice on (i) how the adoption of renewables is affected by energy storage (and vice versa) and (ii) how electricity pricing, technological progress, and subsidy policies can shape the adoption of both technologies.

%K Supply Chain
%X Unlike commercial and industrial sectors where they have been successfully deployed, the rollout of voluntary Time-of-Use (TOU) tariffs in the residential sector has been tepid. One cause for this limited penetration of TOU tariffs in the residential sector is the difficulty in offering appropriate price incentives to a consumer class that is heterogeneous in its demographics and preferences. In this paper, we develop a parsimonious game-theoretic model to shed light on the optimal pricing problem from the utility's perspective when its consumers vary in their electricity consumption scheduling preferences as well as their willingness or flexibility to shift consumption in response to price incentives offered by the utility. Using this model, we generate structural insights into the role of the two types of consumer heterogeneity on the design and potential of voluntary TOU tariffs. We also show how our model and insights can be used to evaluate the current state and potential of TOU tariffs in two U.S. states.

%K Supply Chain
%X We investigate the causes behind the underwhelming adoption of voluntary Time-of-Use (TOU) tariffs in the residential electricity market. TOU tariffs are deployed by utilities to better match electricity generation capacity with market demand by giving consumers price incentives to reduce their consumption when electricity demand is at its peak. However, consumers in residential electricity markets are heterogeneous in their consumption preferences. Hence, utilities face a trade-off when deploying voluntary TOU tariffs---to provide aggressive price incentives that will only appeal to consumers with flatter profiles or milder incentives to appeal to a larger proportion of the market. Using a game-theoretic model, we identify the key factors that determine the viability of voluntary TOU tariff deployment. On the supply side, the gap between wholesale prices in the peak and off-peak periods determines how much the utility stands to benefit by inducing demand response. On the demand side, heterogeneity within target consumer sets determines how much demand response the utility can induce with a certain price incentive. We show that misaligned incentives between utilities and regulators lead to underwhelming TOU tariff adoption compared to the socially desirable level, and that this under-adoption is worse when consumption preferences are uniformly distributed. We also evaluate the degree of cross-subsidization across tariff structures to identify their implications for equity among the different consumer types, and find that low levels of voluntary TOU adoption are less equitable than the default tariffs.

%T Determinants of Excess Inventory Announcement and Stock Market Reaction in the Retail Sector
%A Lee,Hyun-Seok (Huck)
%A Kesavan,Saravanan
%K Supply Chain
%X In this paper, we empirically analyze the determinants of excess inventory announcement and the stock market reaction to the announcement in the US retail sector. We examine if the firm’s operational competence, as measured by total factor productivity (TFP), can explain the retailer’s excess inventory announcement. We also investigate if the stock market reaction to such announcements is conditional on the operational competence of the announcing firm. We use a combined dataset on excess inventory announcements, annual financial statements, and daily stock prices of publicly traded retailers in the USA between 1990 and 2011. We find that operationally competent retailers have a lower probability of announcing excess inventory in the following year. In addition, the stock market penalizes excess inventory announcements made by operationally competent retailers more severely than those made by their less competent peers. Finally, providing action information, which the firm has taken or plans to take to deal with the excess inventory, moderates the negative association between firm’s operational competence and abnormal returns due to the announcement, whereas we do not find such moderating effect with reason information.

%A Murali,Karthik

%K Supply Chain
%X Problem definition: We develop a framework for studying the impact of voluntary ecolabels and mandatory environmental regulation on green product development among competing firms. Academic/practical relevance: We contribute to the academic literature on environmental quality competition by explicitly accounting for the credibility of environmental claims made by firms, and by exploring the implications for society of two mechanisms used to remedy credibility-related consumer discounting of firms’ self-declared environmental qualities. We draw parallels between our findings and instances of environmental labeling and regulation from industry to highlight the practical implications of our study. Methodology: We use a game-theoretic framework to analyze a consumer-driven model of green product development. Results: Credibility asymmetry drives product differentiation between two competing firms. The less credible firm always adopts external certification, while the more credible firm does so only if its credibility is sufficiently low. Credibility may also determine whether or not the government should intervene. In the absence of an external certifier, the regulator should intervene by imposing a mandatory environmental standard that is decreasing in stringency as the credibility of the more credible firm increases. In the presence of a certifier, the regulator should intervene if neither firm is sufficiently credible, or if consumers do not value environmental stewardship highly. Managerial implications: We identify how and when government should (and should not) intervene to stimulate green product development when competing firms can use self-labels or external certifications to communicate their environmental performance to consumers. We also determine the optimal strategies for the competing firms and external certifiers.

%K Supply Chain
%X The purpose of this study is to investigate the impact of national culture on the effectiveness of bonus and penalty contract incentive structures in supply chain exchanges. We conduct laboratory experiments in Canada, China, and South Korea, involving transactional exchanges in which suppliers are presented with either bonus or penalty contracts. We then evaluate suppliers’ contract acceptance, effort level, and shirking comparatively across national culture. Our findings reveal critical cultural influences on contract efficacy. We show that while acceptance of bonus contracts is comparable across cultures, suppliers from Canada, associated with a national culture low in power distance and high in humane orientation, exhibit lower acceptance rates on penalty contracts. We also find some evidence that suppliers associated with collectivist cultures reward bonus contracts with greater effort and less shirking, but that these relationships are more complex. When contract effectiveness is compared across bonus and penalty contracts within a given cultural setting, we find that bonus contracts are accepted more than penalty contracts in all three countries. Also, after contracts are accepted, bonus contracts are more successful in China as suppliers exert higher efforts and shirk less under bonus contracts than penalty contracts, while accepted contracts are nearly indistinguishable in Canada and South Korea.

%X Original equipment manufacturers increasingly involve suppliers in new product development (NPD) projects. How companies design a contract to motivate supplier participation is an important but under-examined empirical question. Analytical studies have started to examine the optimal contract that aligns buyer-supplier incentives in joint NPD projects, but empirical evidence is scarce about the actual contracts offered by buying companies. Bridging the analytical and empirical literature, this paper compares optimal contracting derived from a parsimonious analytical model with actual behaviors observed in an experiment. In particular, we focus on how project uncertainty, buying company effort share, and buyer risk aversion influence three contractual decisions: total investment level, revenue share and fixed fee. Our results indicate significant differences between the optimal and actual behaviors. We identify various types of non-optimal contractual behaviors, which we explain from a risk aversion as well as a bounded rationality perspective. Overall, our findings contribute to the literature by showing that (1) the actual contractual behaviors could differ significantly from the optimal ones, (2) the actual contract design is sensitive to changes in project uncertainty and buying company effort share, and (3) the significant roles of risk aversion and bounded rationality in explaining the non-optimal contractual behaviors.

%X We present a spatialization of digital library content based on item similarity and an experiment which compares the performance of this spatialization relative to a simple list-based display. Items in the library are K-12 science and engineering learning resources. Spatialization and visualization are accomplished through 2D interactive Sammon mapping of pairwise item similarity scores based on the joint occurrence of word bigrams. The 65 science teachers participating in the experiment were asked to search the library for curricular items they would consider using in conducting one or more teaching assignments. Results indicate that whereas the spatializations adequately capture the salient features of the library’s content and teachers actively use them, item retrieval rates, task-completion time and perceived utility do not significantly differ from the semantically poorer but easier to comprehend and navigate list-based representations. These results put into question the usefulness of the rapidly increasing supply of information spatializations.

%X We report on a process for similarity estimation and two-dimensional mapping of lesson materials stored in a Web-based K12 Science, Technology, Engineering and Mathematics (STEM) digital library. The process starts with automated removal of all information which should not be included in the similarity estimations followed by automated indexing. Similarity estimation itself is conducted through a natural language processing algorithm which heavily relies on bigrams. The resulting similarities are then used to compute a Sammon-map; i.e., a projection in n dimensions, the item-to-item distances of which best reflect the input similarities. In this paper we concentrate on specification and validation of this process. The similarity results show almost 100% precision-by-rank in the top three to five ranks. Sammon mapping in two dimensions corresponds well with the digital library‘s table of content.

%K Supply Chain
%X We study a municipal groundwater management problem to determine optimal allocation and control policies in the presence of water transfer opportunities. We establish and characterize threshold polices governing export or import decisions of a given municipality. In the spirit of the Triple Bottom Line (3BL), we ascertain that exporting (importing) water through a water market defined by an exogenous export/import price is detrimental (beneficial) to both society and the environment within the municipality. In contrast, fixed quantity trading between two municipalities defined by an endogenously negotiated export/import price can have positive as well as negative impacts from a global 3BL perspective. In particular, typical trading scenarios that occur between municipalities can be detrimental to the environment. We also study the implications of privatization, and find that a privatized municipality would be more (less) likely to export (import) water as compared to its non‐privatized counterpart, resulting in negative implications for society within the municipality. However, if exports are banned, privatization can benefit the environment by mitigating the damage caused by the extraction differential, a phenomenon analogous to the green paradox. Moreover, careful and restricted privatization of municipalities can lead to positive global 3BL impacts from fixed quantity trading.

%X Power generation for the existing electrical grid is largely based on the combustion of fossil fuels. Global concerns have been raised regarding the environmental sustainability of the system due to life cycle impacts, including land losses from fuel extraction and impacts of combustion emissions. An approach to reduce carbon emissions of fossil fuel-based energy employs the conversion of wind energy to electrical energy. The work presented describes modern wind power plants and provides an environmental assessment of a representative wind park from a life cycle perspective. The empirical analysis uses commercially available data, as well as information from an existing wind power plant. The life cycle assessment (LCA) study for a modern wind farm in the northwestern U.S. found that environmental benefits of avoiding typical electricity production greatly outweigh the impacts due to wind turbine construction and maintenance. Effects of component reliability, varying capacity factors, and energy portfolio are explored.

%K Supply Chain
%X This paper investigates the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between economic growth and environmental stewardship in the context of China’s emerging ‘circular economy’ policy paradigm and based on ecological modernization theoretic approaches. Based on three company case studies in the information technology and electronic industries in China, we identify and demonstrate how a blended business and environmental value can be created from adopting a sustainable supply chain management approach. The adoption of a sustainable supply chain management approach is rapidly becoming a key business challenge and opportunity in China and other large emerging economies around the world, where our greatest environmental management challenges currently reside and will continue to exist for many years to come. The value creation framework proposed in research focuses on evaluating three case study companies who appear in various stages of an electronic industry supply chain. Value creation within a supply chain can provide the impetus for organizations to adopt circular economy, sustainable supply chain practices, for competitive reasons. In addition, we describe how a value proposition can be evaluated at two levels of analysis, a more specific micro-level and a more general meso-level of analysis. The four major business value dimensions include cost reduction, revenue generation, resiliency, and legitimacy and image. The initial findings are that a variety of opportunities exist for electronic firms in emerging and developing countries, while results from this study provide an important scholarly foundation to develop and refine sustainable supply chain management practices in emerging and developing economies.

%K Supply Chain
%X This article examined the degree to which a supply manager's intrapreneurial ability influences the quality of individual-level relationships with internal customers and the supplier's account executive. The moderating influence of the buyer's firm-level commitment to the supplier and how these relationships subsequently impact supplier performance were explored. The study assessed the supply manager's intrapreneurial ability using survey data gathered from 110 supply managers across a variety of industries. In key supplier relationships, a supply manager's intrapreneurial ability positively influences the quality of internal and external relationships. The firm's commitment to the supplier weakens the relationship between intrapreneurial ability and relationship quality. The findings highlight the value of individual skills to enhance relationships The ability to behave intrapreneurially shapes the quality of internal and supplier relationships. However, only the supply manager's relationship with the supplier's account executive is related to supplier performance. By examining the impact of intrapreneurial ability on individual-level relationships with internal customers and supplier's account executive, a more comprehensive view of business-to-business relationship management in the supply chain is gained.

%K Supply Chain
%X A growing number of studies and evidence from industries suggest that, besides managing the relationship with its suppliers, a buyer needs to proactively manage the relationships between those suppliers. In a buyer–supplier–supplier relationship triad, the buyer, as the contracting entity, influences the suppliers’ behaviors and the relationship between them. By considering the relationships in such a triad, we are able to gain a richer and more realistic perspective of buyer–supplier relationships. In this study, our goal is to examine supplier–supplier relationships in buyer–supplier–supplier triads, focusing on how such relationships impact the supplier performance. We frame the supplier–supplier relationship as co-opetition—one in which competing suppliers work together to meet the buyer's requirements. We investigate the role of the buyer on such relationships, and how the buyer and co-opetitive supplier–supplier relationships affect supplier performance. We find mixed empirical support for our hypotheses. However, we are able to demonstrate the dynamics of supplier–supplier co-opetition in the buyer–supplier–supplier triad. We point out the need for further studies in this area.

%X Purchasing portfolios are a well accepted part of the supply chain literature. Yet during a recent data collection effort we observed that a number of leaders in sustainable supply chain management were not organizing their purchasing portfolios in the manner suggested by Kraljic (1983). Specifically, we found evidence of organizations buying what would traditionally be leveraged commodities in a manner more suited to strategic suppliers. This manuscript describes the observed phenomena and then uses theory to try and explain our observations. The end result is a modified sustainable purchasing portfolio model.

%X Case studies of 10 exemplar firms are used to build a coherent and testable model of the elements necessary to create a sustainable supply chain. The cases build on previous research by examining the chain as an entirety, by explicitly examining both the social and environmental outcomes of the chain's activities, and by explicitly asking what these exemplar organizations are doing that is unique in regards to managing their supply chains in a sustainable manner. The analysis suggests that the practices that lead to a more sustainable supply chain are equal parts best practices in traditional supply chain management and new behaviors, some of which run counter to existing accepted “best” practice.

%X A censored stochastic volatility model is developed to reconstruct a return series censored by price limits, one popular form of market stabilization mechanisms. When price limits are reached, the observed prices are truncated and the equilibrium prices are unobservable, which makes further financial analyses difficult. The model offers theoretically sound estimates of censored returns and is demonstrated via simulations to outperform existing approaches with respect to the estimates of model parameters, unconditional means, and standard deviations. The algorithm is applied to model stock and futures returns and results are consistent with the simulation outcomes.<br><br>

%T Extreme Value Analysis for Partitioned Insurance Loss
%A Henry III,John B.
%A Hsieh,Ping-Hung
%K Supply Chain
%X The heavy-tailed nature of insurance claims requires that special attention be put into the analysis of the tail behavior of a loss distribution. It has been demonstrated that the distribution of large claims of several lines of insurance have Pareto-type tails. As a result, estimating the tail index, which is a measure of the heavy-tailedness of a distribution, has received a great deal of attention. Although numerous tail index estimators have been proposed in the literature, many of them require detailed knowledge of individual losses and are thus inappropriate for insurance data in partitioned form. In this study we bridge this gap by developing a tail index estimator suitable for partitioned loss data. This estimator is robust in the sense that no particular global density is assumed for the loss distribution. Instead we focus only on fitting the model in the tail of the distribution where it is believed that the Pareto-type form holds. Strengths and weaknesses of the proposed estimator are explored through simulation and an application of the estimator to real world partitioned insurance data is given.

%X We investigate the magnet effect of price limits using transaction data from the Taiwan Stock Exchange. A logit model incorporates explanatory variables from microstructure literature and reveals that the conditional probability of a price increase (decrease) increases significantly when the price approaches the upper (lower) price limit, in support of the magnet effect. Our approach recognizes when the magnet effect starts to emerge and identifies possible determinants of magnet effect. The probability of information-based trading has a significant impact on the magnet effect for lower price limits.<br><br>

%T Taking the Leap from Dyads to Triads: Buyer-Supplier Relationships in Supply Network.
%A Choi,Thomas

%K Supply Chain
%X A network is made up of nodes and links. The smallest unit that consists of both these network elements is a dyad made up of two nodes (a buyer and a supplier) and the link that connects them (a buyer–supplier relationship).<br><br>Naturally, the focus of the supply chain management literature has been on this dyad. For instance, a buyer affects a supplier through its supplier evaluation and certificate programs, as well as long-term agreement practices. The relationship between a buyer and its supplier has been characterized as cooperative or adversarial. We have learned a great deal about supply chains through such studies in dyadic context.<br><br>However, we submit that in a network, a dyad is not the smallest unit of a network. In fact, the smallest unit is a triad, made up of three nodes and the links that connect them. If so, how would this recognition guide us as we move forward to investigate supply chains as a network? What would be its implications to the genre of the literature on buyer–supplier relationships?

%T Triads in Supply Networks: Theorizing Buyer–Supplier–Supplier Relationships
%A Choi,Thomas
%A Wu,Zhaohui
%K Supply Chain
%X Past studies in supply chain management have focused on dyadic relationships (e.g., buyer–supplier), as all relationships in a network begin with a dyad. However, dyads do not capture the essence of a network. We posit in this paper that triads are the fundamental building blocks of a network. To begin considering triads in supply networks, we build on two extant bodies of literature — the buyer–supplier relationship and supplier–supplier relationship literature which offer us the context of buyer–supplier–supplier triads. By doing so, we are taking the first step toward cracking the internal dynamics of triads in supply networks. To build theoretical propositions, we apply balance theory and the structural-hole concept. We identify nine triadic archetypes of buyer–supplier–supplier relationships and state key propositions that aid in decision making in supply networks.

%K Supply Chain
%X Applying concepts from the behavioral complexity literature (Ashby, 1952; Denison, Hooijberg, and Quinn, 1995) we examine if supply managers’ multiple roles and the ability to shift among these roles is related to their interpersonal relationship with their key contact within the strategic suppliers’ organization and ultimately with the firm-to-firm relationship. Case studies identified four supply manager roles that are assumed when managing relationships with strategic suppliers: negotiator, facilitator, supplier’s advocate, and educator. Survey data were gathered from 59 pairs of supply managers and their key contact in a strategic supplier’s organization. Results show that a larger behavioral repertoire is positively related to interpersonal relationships but higher behavioral differentiation is negatively related to interpersonal relationships. Interpersonal relationships are positively related to firm-to-firm relationships. Limitations and opportunities for future research are discussed.

%X When design decisions are made by a group of diverse stakeholders, the decision making process is affected by both technical and social dynamic factors and the design results are consequently a product of the joint influences. Though it is important, the role of social dynamic factors in design process is currently not well understood. In this work, our study is focused on a prioritising problem concerning understanding customer needs at the early stage, in particular, identifying Quality Requirements and their relative importance. We introduced one among many social dynamic factors, i.e. trust and investigated its role in the early stage design decision making of product development. Derived from the definition and principle forms of general trust, the trust concept used in the prioritising problem for our study is specified. The existing measurement scales used in social science are modified for measuring the trust in terms of trustworthiness.

%X Until recently, end-of-life (EOL) product management was the purview of a small number of firms that could make money out of recycling and/or remanufacturing. Now, changing customer expectations and stringent product take-back regulations are forcing many goods producing organizations to confront EOL product management, even in cases in which there is no clear economic incentive for doing so. This article presents a framework that highlights the supply chain implications for firms forced into EOL product management where recycling is the only viable option. Discussed are the various recycling options available to managers, as well as the strategic implications of each of these choices.

%K Supply Chain
%X Supply chain managers recognise that seamless supply chain operations require a high level of integration within and across organisations. Existing study and management focus have dealt with how to integrate supply chain activities across different organisations. However, it is not clear how a company should integrate supply chain functions within the company. One might assume that integration of the internal supply chain is easy to accomplish because top management has control over the functional areas. Yet, many companies suffer from supply chain disruptions due to internal coordination problems. As we started to investigate this issue we realised that the level of internal supply chain integration varies significantly from company to company. This discovery motivated us to take a systematic approach to investigating how companies integrate their internal supply chain. This study reports our findings with a focus on prescribing behaviours that managers can use to guide internal integration efforts.

%K Supply Chain
%X Many researchers have studied how the buying company manages its relationship with suppliers (i.e. buyer”supplier relationship). Extending this genre of study, researchers have recently shown interest in investigating how the buying company manages relationships between the suppliers (i.e. supplier”supplier relationship). In other words, just as the relationship with the suppliers does, the relationships between suppliers have strategic implications for the buyer. We present in this study eight cases that describe supplier”supplier relationship dynamics. Using theory building through case studies, we identify five archetypes of supplier”supplier relationships. Each type of relationship is a unique configuration of the relational characteristics. We also present working propositions that associate the antecedent conditions that lead to these archetypes and eventual performance implications.

%T A Data-Analytic Method for Forecasting Next Record Catastrophe Loss
%A Hsieh,Ping-Hung
%K Supply Chain
%X We develop in this article a data-analytic method to forecast the severity of next record insured loss to property caused by natural catastrophic events. The method requires and employs the knowledge of an expert and accounts for uncertainty in parameter estimation. Both considerations are essential for the task at hand because the available data are typically scarce in extreme value analysis. In addition, we consider three-parameter Gamma priors for the parameter in the model and thus provide simple analytical solutions to several key elements of interest, such as the predictive moments of record value. As a result, the model enables practitioners to gain insights into the behavior of such predictive moments without concerning themselves with the computational issues that are often associated with a complex Bayesian analysis. A data set consisting of catastrophe losses occurring in the United States between 1990 and 1999 is analyzed, and the forecasts of next record loss are made under various prior assumptions. We demonstrate that the proposed method provides more reliable and theoretically sound forecasts, whereas the conditional mean approach, which does not account for either prior information or uncertainty in parameter estimation, may provide inadmissible forecasts.

%T Interdependence and its Consequence in Distributor-Supplier Relationships: A Distributor Perspective Through Response Surface Approach
%A Kim,Steve
%A Hsieh,Ping-Hung
%K Marketing
%K Supply Chain
%X Interdependence and its consequences in marketing channels have received substantial research attention, but two issues remain unresolved. First, the validity of the extant methods to measure interdependence has not been verified, and those methods have not been contrasted. Second, the impact of interdependence on an outcome variable is difficult to analyze and its potential to provide managerial insight hampered. To address those gaps, the authors first review prior approaches. The review of prior approaches raises key methodological and theoretical issues in measuring interdependence and analyzing its impacts, including the additivity of distributor and supplier dependences for measurement of interdependence and the nonlinear functional forms of dependences for the impact of interdependence.The authors use the response surface approach (RSA) and derive three managerial insights that can be garnered from its use: interdependence for the highest (lowest) level of an outcome, directions for change in interdependence, and change in outcome when receding from the ideal combination. They apply RSA to the relationship between interdependence and three outcome variables—distributor commitment, bilateral communication, and supplier control—in industrial distributor”supplier relationships and contrast it with previous methods.  The empirical study results suggest that (a) distributors perceive differential effects of supplier dependence and distributor dependence on outcome variables and (b) highest magnitude and lowest asymmetry of interdependence do not lead to the highest distributor commitment or supplier control. From a distributor's standpoint, highest commitment and supplier control occur when distributor dependence is high and supplier dependence is modest. The following implications emerge: Distributor dependence and supplier dependence must be decoupled and treated separately. Distributor dependence can be encouraged and nurtured, while supplier dependence needs to be kept moderate. A supplier's too little or too great dependence on a distributor will deteriorate channel outcomes, at least from a distributor's point of view.

%K Strategy & Entrepreneurship
%K Supply Chain
%X The impact of research and development (R&D) on firm performance is generally agreed to be positive, but the nature and extent of this impact share little agreement in the previous research. Using an improved, time series, cross-sectional regression model that accounts for both contemporaneous and firm-specific serial correlation, as well as the feedback between firm profitability and investments, our study compares the rate of return from a dollar investment on R&D to a dollar investment on fixed assets in pharmaceutical and chemical industries. We find positive associations of R&D intensity and all variables of firm performance (net margin, operating margin, sales growth, and market value). We find that an investment in R&D earns an operating margin return much higher than the industry cost of capital. We also find that the effect of an investment in R&D on the firm's market value is about twice as much the effect of an investment in fixed assets. These findings have implications for corporate investment strategies, indicating that additional R&D investment is more likely to provide a firm with a unique and sustainable competitive advantage.

%X Our paper provides a comprehensive assessment of 285 survey research articles in operations management (OM), published between 1980 and 2000. Six OM journals are included in this study; they are, in alphabetical order: Decision Sciences (DS), International Journal of Operations & Production Management (IJOPM), International Journal of Production Research (IJPR), Journal of Operations Management (JOM), Management Science (MS), and Production and Operations Management (POM). In this paper, we reflect upon the state and evolution of survey research in the OM discipline across a 21-year time span and the contribution of OM journals that have published these studies. Major changes have occurred in the last 5 years of our sampling period, and two topics stood out as showing fastest ascendancy to prominence—operations strategy and supply chain management. Furthermore, over the years, the Journal of Operations Management appears to have been publishing more survey research articles and a greater variety of OM topics compared to the other five journals in our study.

%T An Exploratory First Step in Teletraffic Data Modeling: Evaluation of Long-run Performance of Parameter Estimators
%A Hsieh,Ping-Hung
%K Supply Chain
%X Examination of the tail behavior of a distribution F that generates teletraffic measurements is an important first step toward building a network model that explains the link between heavy tails and long-range dependence exhibited in such data. When knowledge of the tail behavior of F is vague, the family of the generalized Pareto distributions (GPDs) can be used to approximate the tail probability of F, and the value of its shape parameter characterizes the tail behavior. To detect tail behavior of F between two host computers on a network, the estimation procedure must be carried out over all possible combinations of host computers, and thus, the performance of the estimator under repeated use becomes the primary concern. In this article, we evaluate the long-run performance of several existing estimation procedures and propose a Bayes estimator to overcome some of the shortcomings. The conditions in which the procedures perform well in the long run are reported, and a simple rule of thumb for choosing an appropriate estimator for the task of repeated estimation is recommended.

%T On Bayesian Predictive Moments of Next Record Value Using Three-parameter Gamma Priors
%A Hsieh,Ping-Hung
%K Supply Chain
%X A forecasting model of next record value proposed by Hill [1] assumes the underlying distribution F(x) is of an algebraic functional form with a shape parameter a for large x. That is, 1 - F(x) ?Cx-a, for large x. In this article, we extend his model by incorporating a three-parameter Gamma prior of a to derive analytical solutions of the predictive distribution and moments of X given that X is a new record value. These closed-form formulas can be represented as ratios of moments of Gamma distributions. We apply the proposed model to a real-life data set that consists of the insured property losses of 33 catastrophes caused by tropical storms in the United States in 1995. The example illustrates the importance of incorporating prior experience and accounting for uncertainty in parameter estimation when forecasting record values. Both considerations are the main ingredients in the development of the proposed model.

%T Modeling the Frequency and Severity of Extreme Exchange Rate Returns
%A Hsieh,Ping-Hung
%K Supply Chain
%X Risk managers are often concerned about tail probabilities of asset return distributions, in particular the frequency and severity of extreme returns. In this article, we propose a model that integrates extreme value theory and point processes to model the frequency and severity of exchange rate returns. The proposed model is applied to daily spot exchange rate series and the parameters of interest, such as the tail index, the mean size and rate of occurrence of extreme returns, are estimated using maximum likelihood estimation. We study the impact of recent currency crises on the frequency and severity of the series and find that, during 1995-9, the frequency of extreme daily Japanese yen-US dollar spot exchange rate returns increases twofold, and the time duration of high volatility persists longer for the Japanese yen series than for the Swiss franc and Danish krone series.

%T Robustness of Conditional Moments: An Application to Premium Calculation for Reinsurance Treaties
%A Hsieh,Ping-Hung
%K Supply Chain
%X In this study, the tail probability of a class of distributions commonly used in assessing the severity of insurance losses was examined. Without specifying any particular distribution, the use of an algebraic functional form Cx to approximate the tail behavior of the distributions in the class was demonstrated. Norwegian fire insurance data were examined, and the algebraic functional form was applied to derive the expected loss of a reinsurance treaty that covers all losses exceeding a retention limit. It was shown that (1) the expected loss is insensitive to the parameter á for a high retention limit (e.g., a catastrophe treaty), and (2) with a low retention limit (e.g., a largest claim treaty), a reliable estimate of the parameter á and a sound judgment on the maximum potential loss of the treaty could provide useful and defensible summary statistics for pricing the treaty. Thus, when dealing with the losses of certain reinsurance treaties, it was concluded that knowledge of a specific probability distribution is not critical, and the summary statistics derived from the model are robust with respect to a large class of loss distributions.

%T Robustness of Tail Index Estimation
%A Hsieh,Ping-Hung
%K Supply Chain
%X The implementation of the Hill estimator, which estimates the heaviness of the tail of a distribution, requires a choice of the number of extreme observations in the tails, $r$, from a sample of size $n$, where $2 \leq r+1 \leq n$. This article is concerned with a robust procedure of choosing an optimal $r$. Thus, an estimation procedure, $\delta_s$, based on the idea of spacing statistics, $H^{(r)}$, is developed. The proposed decision rule for choosing $r$ under the squared error loss is found to be a simple function of the sample size. The proposed rule is then illustrated across a wide range of data, including insurance claims, currency exchange rate returns, and city size.

%T Informal Cross-Border Trade in Africa: Operations, Policy, and Opportunities
%A Park,Jimin

%K Supply Chain
%X Informal cross-border trade (ICBT) refers to the illegal activities of cross-border commerce conducted by unregistered small-scale traders. We seek to develop insights to understand the ICBT value chain and offer policy recommendations to successfully integrate it into the formal economy. Using a game-theoretic model, we analyze the operations and key market dynamics of ICBT. We analyze the policy implications of three representative UN directives: enhancing marginalized traders' access to formal channels, reducing export tax rates for formal traders, and introducing an alternative simplified trade regime (STR) for informal traders. All three policies result in an increase in government proceeds when the inherent profitability of the formal or STR channels is sufficiently high. Furthermore, social welfare increases when the policies effectively balance wholesale price competition within the formal and informal channels. We apply our model to a case study based on Uganda's agricultural exports over an 11-year horizon. The access enhancement policy is most effective in increasing government proceeds but least effective in improving the welfare of other participants. The tax reduction policy enhances traders' profitability but sacrifices the welfare of farmers and government proceeds substantially. Finally, the STR acknowledgement policy results in the largest increase in profitability of marginalized traders and farmers but comes at the cost of government proceeds.
