Publication Metadata only Preface of the special issue on global multiobjective optimization(Springer, 2021) Miettinen, Kaisa; Department of Business Administration; Sayın, Serpil; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 6755N/APublication Metadata only How, when, and why do attribute-complementary versus attribute-similar cobrands affect brand evaluations: a concept combination perspective(Oxford Univ Press Inc, 2015) Swaminathan, Vanitha; Kubat, Umut; Department of Business Administration; N/A; Canlı, Zeynep Gürhan; Şanlı, Ceren Hayran; Faculty Member; PhD Student; Department of Business Administration; College of Administrative Sciences and Economics; Graduate School of Business; 16135; 275215Extant research on cobranding does not examine when and why complementarity or similarity between cobranding partners can be more effective. This research examines consumers' reactions to cobranded partnerships that feature brands with either complementary or similar attribute levels, both of which are common in the marketplace. The results of six experiments show that consumers' evaluations vary as a function of concept combination interpretation strategy (property mapping or relational linking) and whether cobranded partners have complementary or similar attributes. Specifically, when consumers use property mapping, they evaluate cobranded partnerships with complementary (vs. similar) attribute levels more favorably. In contrast, when using relational linking, they evaluate cobranded partnerships with complementary (vs. similar) attribute levels less favorably. The results also reveal that the breadth of the host brand (broad vs. narrow) and the type of advertising influence the extent to which consumers are likely to use property mapping or relational linking in evaluating cobranded partnerships.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 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 A bourdieuan relational perspective for entrepreneurship research(Wiley, 2014) Tatli, Ahu; Vassilopoulou, Joana; Forson, Cynthia; Slutskaya, Natasha; Department of Business Administration; Özbilgin, Mustafa; Other; Department of Business Administration; College of Administrative Sciences and Economics; N/AIn this paper, we illustrate the possibilities a relational perspective offers for overcoming the dominant dichotomies (e.g., qualitative versus quantitative, agency versus structure) that exist in the study of entrepreneurial phenomena. Relational perspective is an approach to research that allows the exploration of a phenomenon, such as entrepreneurship, as irreducibly interconnected sets of relationships. We demonstrate how Pierre Bourdieu's concepts may be mobilized to offer an exemplary toolkit for a relational perspective in entrepreneurship research.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 Analysis of multistation production systems with limited buffer capacity part:2 the decomposition method(Pergamon-Elsevier Science Ltd, 1997) Yeralan, S.; Department of Business Administration; Tan, Barış; Faculty Member; Department of Business Administration; College of Administrative Sciences and Economics; 28600We seek efficient techniques to evaluate the performance of multistation production systems with limited interstation buffers and station breakdown. Our ultimate objective is to develop a practical computer implementation that can be used for analysis and design. A flexible decomposition framework is developed. This approach allows the analysis of multistation production systems with various structures including series arrangements, network topologies, and rework (feedback) systems. The efficient solution techniques for the subsystems developed in Part 1 are used at each iteration of the decomposition method. It is the generality and efficiency of the subsystem model as well as the flexibility and robustness of the decomposition approach that distinguish our study from earlier work.
