Publication Metadata only Value creation in service delivery: relating market segmentation, incentives, and operational performance(Institute for Operations Research and the Management Sciences, 2004) Güneş, Evrim D.; Department of Business Administration; Karaesmen, Zeynep Akşin; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 4534This paper studies service-delivery design in settings where firms engage in value-creation activities that have the objective of generating additional revenue from customer interactions. The paper provides a general modelling framework to analyze the ties between market segmentation decisions, incentives, and process performance in such service-delivery systems. The firm is modelled as a single-server queue, in a principal-agent framework. Customers have different value-generation potentials whose realizations are observed by the server but not by the manager of the firm. The manager determines a market segmentation scheme given an overall customer value-generation profile, which divides customers into two groups (high and low), and also determines a service level for each segment. The server decides which of the two available service levels (high and low) to provide for each customer, given a compensation scheme offered by the manager. The optimal market segmentation decision, optimal service-level choice, and a set of optimal linear incentive contracts that enable their implementation are characterized. The robustness of these strategies is explored with respect to model parameters and assumptions. It is shown that a market segmentation scheme that combines revenue generation concerns with their process implications is essential for success. Characteristics of appropriate incentive schemes are identified.Publication Metadata only Knowledge processes and learning outcomes in MNCs: an empirical investigation of the role of HRM practices in foreign subsidiaries(Wiley, 2009) Simonin, Bernard L.; Department of Business Administration; Tunalı, Ayşegül Özsomer; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 108158By examining the case of American and European firms operating in Japan, this article contributes to the central debate of how and when multinational corporations (MNCs) learn from their foreign subsidiaries. Through structural equation modeling, we assess how specific human resource management (HRM) practices (critical thinking encouragement, supervisory encouragement, learning incentives, deployment of internal mechanisms and processes, expatriation, and corporate training) enhance (1) knowledge transfer outflows from the subsidiary to other parts of the MNC and (2) the subsidiary's performance in its local market. We find learning orientation to be a key antecedent of all HRM practices we investigated. From a practical point of view, a noticeable finding relates to the lack of effects of critical thinking encouragement on market knowledge acquisition and dissemination when (1) there is a significant presence of expatriates in the subsidiary and (2) when local managers have access to training programs at headquarters (HQ) and other affiliates.Publication Metadata only Syndicated lending under asymmetric creditor information - Correction(Elsevier, 1996) Cadot, O; Department of Business Administration; Banerjee, Saugata; Researcher; Department of Business Administration; College of Administrative Sciences and Economics; N/AThis paper explores how asymmetric information about borrower quality among syndicated lenders alters the incentive to refinance illiquid borrowers. We use a model in which lenders enter the market sequentially in two rounds of lending. Between the two rounds, a shock separates borrowers into good ones and bad ones, and early entrants acquire information about individual borrower type, while late entrants know only the distribution of borrower types. The asymmetric information structure gives rise to both signalling and screening issues. We show that self-selecting contracts do not exist, and that there is always a pooling Perfect Bayesian Equilibrium in which late entrants lend to both good and bad types, without borrower type being exposed before final clearing at the terminal time. Based on this framework, we argue that prior to the 1982 international debt crisis, it was possible for banks with heavy exposure to troubled debtors to attract rational newcomers in syndicated loans which were, with positive probability, bailout loans.Publication Metadata only Does parent satisfaction with a childcare provider matter for loyalty?(Emerald Group Publishing, 2006) Keiningham, T.L.; Andreassen, T.W.; Estrin, D.; Department of Business Administration; Aksoy, Lerzan; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; N/APurpose - The purpose of this study is to investigate the relationship between parent satisfaction and child retention at a childcare provider. Design/methodology/approach - The survey data used in the analyses involves a sample size of 1,003 respondents, all clients of a regional childcare provider in the USA. Logistic regression was used to test the propositions. Findings - The results indicate that parent satisfaction is most important to child retention when the child is very young (birth to one year of age). As children increase in age, however, parent satisfaction becomes increasingly less predictive of children's continued enrollment at a childcare facility. Research limitations/implications - One of the limitations of this research is that it tests the propositions within a single firm. Future research should attempt to replicate these findings across several childcare providers. Practical implications - Emphasizing improvements in different attributes for different age groups has implications for increasing retention for childcare providers, in addition to ultimately increasing the satisfaction of parents. Originality/value - While all would agree that childcare services are of extremely high importance (at both a national and individual level), no research to date has examined the role of parent satisfaction to the continued enrollment of a child at a childcare facility. Our findings show that the presumed relationship between satisfaction and retention varies greatly by the age of child.Publication Metadata only Transition to family practice in Turkey(Wiley, 2008) Yaman, Hakan; Department of Business Administration; Güneş, Evrim Didem; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 51391Introduction: Turkey's primary health care (PHC) system was established in the beginning of the 1960s and provides preventive and curative basic medical services to the population. This article describes the experience of the Turkish health system, as it tries to adapt to the European health system. It describes the current organization of primary health care and the family medicine model that is in the process of implementation and discusses implications of the transition for family physicians and the challenges faced in meeting the needs for health care staff. In Turkey a trend toward urbanization is evident and more staff positions in rural PHC centers are vacant. Shortages of physicians and an ineffective distribution of doctors are seen as a major problem. Family medicine gained popularity at the beginning of the 1990s, as a specialty with a 3-year postgraduate training program. Medical practitioners who are graduates of a 6-year medical training program and are already working in the PHC system are offered retraining courses. Better working conditions and higher salaries may be important incentives for medical practitioners to sign a contract with the social security institution of Turkey. Discussion: The lack of well-trained primary care staff is an ongoing challenge. Attempts to retrain medical practitioners to act as family physicians show promising results. Shortness of physician and health professionals and lack of time and resources in primary health care are problems to overcome during this process.Publication Metadata only Measuring the quality of discrete representations of efficient sets in multiple objective mathematical programming(Springer, 2000) N/A; Department of Business Administration; Sayın, Serpil; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 6755One way of solving multiple objective mathematical programming problems is ending discrete representations of the efficient set. A modified goal of finding good discrete representations of thr efficient set would contribute to the practicality of vector maximization algorithms. We define coverage, uniformity and cardinality as the three attributes of quality of discrete representations and introduce a framework that includes these attributes in which discrete representations can be evaluated, compared to each other, and judged satisfactory or unsatisfactory by a Decision Maker. We provide simple mathematical programming formulation that can he used to compute the coverage error of a given discrete representation. Our formulations are practically implementable when the problem under study is a multiobjective linear programming problem. We believe that the interactive algorithms along with the vector maximization methods can make use of our framework and its tools.Publication Metadata only Using support vector machines to learn the efficient set in multiple objective discrete optimization(Elsevier, 2009) Aytuğ, Haldun; Department of Business Administration; Sayın, Serpil; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 6755We propose using support vector machines (SVMs) to learn the efficient set in multiple objective discrete optimization (MODO). We conjecture that a surface generated by SVM could provide a good approximation of the efficient set. As one way of testing this idea, we embed the SVM-approximated efficient set information into a Genetic Algorithm (GA). This is accomplished by using a SVM-based fitness function that guides the GA search. We implement our SVM-guided GA on the multiple objective knapsack and assignment problems. We observe that using SVM improves the performance of the GA compared to a benchmark distance based fitness function and may provide competitive results.Publication Metadata only Finite-capacity scheduling-based planning for revenue-based capacity management(Elsevier Science Bv, 1997) Department of Business Administration; Akkan, Can; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; N/AFinite-capacity scheduling can be argued to be a crucial component of revenue-based capacity management. In that case, one way to plan production is to reserve portions of capacity for incoming customer orders as they arrive, in real-time. In such a planning method, the way these work-orders are scheduled affects the useable capacity, due to fragmentation of the time-line. Assuming the work-orders are rejected if they cannot be inserted into the existing schedule, we develop heuristics to minimise the present-value of the cost of rejecting orders and inventory holding cost due to early completion. We perform simulation experiments to compare the performance of these heuristics in addition to some common heuristics used in practice.Publication Metadata only Strategic context of organizational market information processes within the multinational corporation(amer Marketing assoc, 1996) Department of Business Administration; N/A; Gençtürk, Esra; Faculty Member; N/A; Department of Business Administration; College of Administrative Sciences and Economics; N/A; N/A; N/AN/APublication Metadata only Embedding brands within media content: the impact of message, media, and consumer characteristics on placement efficacy(Lawrence Erlbaum Associates, 2003) Malkoc, Selin A; Bhatnagar, Namita; Department of Business Administration; Aksoy, Lerzan; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; N/A[No abstract available]
