Article Citation Count: 24Antecedents and performance outcomes of value-based selling in sales teams: a multilevel, systems theory of motivation perspective(Springer, 2020) Mengüç, Bülent; Mengüç, Bülent; Panagopoulos, Nikolaos G.Firms are increasingly deploying a value-based selling (VBS) approach in their sales organizations to drive growth for new offerings. However, VBS adoption remains challenging, signaling that leaders need guidance to motivate VBS. Drawing from the systems theory of motivation, we examine motivational mechanisms at two levels-salesperson and sales team-to understand how to motivate, and benefit from, VBS. Using multisource data (i.e., salespeople, managers, archival performance) from 70 sales teams in a U.S.-based manufacturing and services provider, our findings illustrate drivers and outcomes of VBS. Specifically, we uncover a framework of salesperson, leader, customer, and team factors that help explain salesperson motivation for VBS. Importantly, we link VBS to customers' adoption of new products to support VBS's role for selling new products. Critical for sales team strategy, our model also integrates a team-level motivational mechanism to provide a comprehensive framework for salesperson and sales team motivations and outcomes.Article Citation Count: 0Babbling through social media: A cross-country study mapping out social networks using eWOM intentions(Springer, 2023) Zülal, İşler; Kıygı-Çallı, Meltem; El Oraiby, MaryamThis research aims to determine the factors affecting the users’ electronic word-of-mouth (eWOM) seeking and sharing intentions and to reveal the interactions among and within clusters using social network analysis (SNA). This study includes three hierarchical sub-studies conducted in two countries, Turkey and Poland. First, we develop a segmentation for social networking site (SNS) users based on the frequency of sharing product-related information on SNSs. Second, we investigate the impact of several factors that affect eWOM seeking and sharing intentions using regression analysis. In the second sub-study, we also include the identified segments developed in the first sub-study as another factor that may have differentiated eWOM intentions. Third, to understand the degree of interaction among SNS users, we apply an SNA using the forecasted eWOM intentions scores from the second sub-study, which gives us hypothetical social networks. The results of SNA present strong interactions inter- and intra-clusters in both countries. Some key findings include the identification of three SNS user segments, including “Middlers,” that may be of particular interest to brands. We also find that in terms of eWOM intentions, users in Turkey are more active than in Poland. Although some predictors of eWOM seeking and sharing intentions differ between the two countries, users intend to be more active in eWOM seeking than in eWOM sharing. The comparative study provides valuable insights for decision-makers to engage different market segments via SNSs with various proposed features using suggested information contents for selected product categories.Article Citation Count: 19Customer Participation Variation and Its Impact on Customer Service Performance: Underlying Process and Boundary Condition(Sage Publications, 2020) Mengüç, Bülent; Auh, Seigyoung; Wang, FatimaDrawing on the customer participation (CP) literature, this research proposes that CP variation is the degree to which employees perceive variability across customers with regard to customers sharing information, time, and effort and making suggestions to enhance the service delivery process and outcome. Drawing on the job demands-resources model, this research explicates the mediating process by which CP variation affects customer service performance and its boundary conditions. Study 1 uses data from a field study in the banking industry to show that CP variation negatively influences customer service performance through greater customer-related burnout. The authors show that this mediation process is moderated by contingencies that mitigate or exacerbate the indirect relationship. Study 2 further validates the CP variation construct by testing for discriminant validity against similar and related constructs, such as CP quality, in more diverse service industries (insurance, legal consulting, travel and tourism, health care, and physical fitness). Finally, an examination of the moderating role of CP quality provides a more nuanced picture of the intricacies between CP variation and CP quality. This article concludes with a discussion of the theoretical and practical implications for CP variation research.Article Citation Count: 21Efficiency analysis of emergency departments in metropolitan areas(Elsevier, 2020) Uray, Nimet; Karadayı, Melis Almula; Ekinci, Yeliz; Ulengin, Füsun; Uray, Nimet; Karaosmanoğlu, ElifThe demand in the healthcare industry is increasing exponentially due to aging population of the world and this is leading to a rapid increase in the cost of healthcare. The emergency departments of the hospitals are the frontline of health care systems and play an additional critical role in providing an efficient and high-quality response for patients. The overcrowding at the emergency departments due to growing demand results in a situation where the demand for ED services exceeds the ability to provide care in a reasonable amount of time. This has led countries to reconsider their health policies in a way to increase their efficiency in their healthcare systems in general and in emergency departments, in particular. As in many countries, there has been a steady and significant increase in the number of patients that seek health services at the emergency departments of state hospitals of Turkey, due to the significant structural reforms in health services since 2003. While meeting this increasing demand, it is ever more important to provide these critical health services efficiently. Therefore, the efficiency of the emergency departments of seven general hospitals run by Istanbul's Beyoglu State Hospitals Association have been analyzed using categorical Data Envelopment Analysis (DEA) models. The analysis of DEA results is supported by a set of statistical methods to make it easier for the hospital administrators to interpret the analysis and draw conclusions. The analysis shows that less-equipped EDs are supported by better equipped, larger EDs, resulting in a hub-and-spoke type of structure among the EDs where "satellite" EDs serve an important referral function and thus evaluating their efficiency without taking the interoperability among these units into account would not be an accurate assessment of their performance.Article Citation Count: 13Empirical Evidence of Revenue Management in the Cruise Line Industry(Sage Publications Inc, 2019) Ayvaz Çavdaroğlu, Nur; Gauri, Dinesh K.; Webster, ScottRevenue management (RM) has received considerable attention from both academic and business professionals. It encompasses several techniques regarding capacity allocation pricing and resource management of fixed time-sensitive capacity. RM can be roughly divided into two categories defined by the control mechanism that increases revenue: capacity allocation or price optimization. Our work falls in the latter category. In our model we allow for partial substitutability among products (e.g. a customer making a purchase decision may consider multiple alternatives-different departure dates different destinations different cabin types). We also include marketing expense in addition to prices as a lever for increasing revenue. These features are relevant to dynamic pricing in practice. The method is illustrated with booking data from a cruise company yielding optimal advertising and prices for 300 products. The application of the model results in an increase in revenue in the range of 8%-20%.Article Citation Count: 19Frontline Employee Feedback-Seeking Behavior: How Is It Formed and When Does It Matter?(Sage Publications Inc, 2019) Mengüç, Bülent; Mengüç, Bülent; İmer, Havva Pınar; Uslu, AyparThis research comprises two studies that extend the literature on the proactive behavior of feedback seeking. Study 1 uses cross-sectional data from frontline employees across 51 apparel stores to examine how feedback seeking is formed and under what conditions. The results suggest that the development of feedback-seeking behavior is contingent on a feedback-seeking climate and the relationship between an employee and his or her supervisor. Study 2 uses longitudinal data collected across three time periods from multiple respondents (i.e. frontline employees and managers) not only to replicate the findings from Study 1 but also to explore when feedback seeking matters. The findings reveal that managers should target employees who are less (vs. more) satisfied with their jobs because such employees perceive more instrumental value from feedback as a means to improve customer service and sales performance. The findings from this research provide insights that managers can use to increase feedback-seeking behavior from employees and effectively identify and manage the conditions under which feedback seeking will occur to greater or lesser degrees.Article Citation Count: 122Municipal solid waste management via multi-criteria decision making methods: A case study in Istanbul Turkey(Elsevier Science, 2018) Çoban, Aslı; Ertiş, İrem Fırtına; Çavdaroğlu, Nur AyvazIn contemporary era solid waste management has become an important issue for developing countries. Rapidly increasing population higher life-standards and technological advancements consistently increase the amount and the diversity of solid waste. In such a complicated environment municipal authorities need to develop the most effective disposal solution to manage the ever-growing municipal solid waste. In this study various disposal techniques that are utilized globally are investigated and different scenarios that could be applicable to Turkey are created. These scenarios might also be implementable for other Europe and Central Asia (ECA) countries. For that purpose 8 solid waste disposal scenarios were evaluated via 7 criteria which are determined according to the opinions of the experts from the field. Towards this end three different multi-criteria decision-making methods namely Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) Preference Ranking Organization Method for Enrichment Evaluations (PROMETHEE) I and PROMETHEE II were utilized for the scenario evaluation. Consequently the most appropriate and feasible scenarios are determined. The results indicate the prominence of recycling and landfill technologies for developing countries. The results are consistent by means of all the three methodologies that are used. (C) 2018 Elsevier Ltd.

While the emerging global debate on potential cost-effective responses has produced potential solutions such as cap and trade systems and/or carbon taxes as part of evolving sustainable energy/environmental policies this kind of intellectual inquiry does not seem to be an issue among Turkish policy-making elites. This is mainly due to their miscalculation that pursuing sustainable energy policies is much more expensive in comparison to the utilization of fossil fuels such as natural gas. Nevertheless the pegged prices of an energy sector dominated by natural gas are illusive as both the political risks and environmental damage have not been incorporated into the current cost calculations. This paper evaluates energy policies through a lens of risk management and takes an alternative approach to calculating energy costs by factoring in political risks. This formulation reveals that the cost of traditional fossil-based energy is in fact more expensive than renewable energy. In addition to being environmentally friendly the paradigm shift towards renewable energy policies would provide Turkey with a significant opportunity to stimulate its economy by being one of the first countries to develop green technologies and as a result this burgeoning sector would prompt job creation as well ; mainly due to the externalities.

Yet, consumers' responses to replica (vs. genuine) touristic experiences are mostly overlooked in the literature. In this paper, we propose that consumers' perceptions of authenticity of the replica (vs. genuine) touristic experiences mediate their responses to these experiences. We define three theoretically driven factors that influence the authenticity perceptions of consumers-experience characteristics (restricted experience vs. not restricted experience; within close vs. distant geographical proximity to the genuine) and a consumer characteristic (salient goal: collecting experiences vs. having fun/pleasure), which influence consumers' responses to replica and genuine touristic experiences. We found support for the proposed theory using two field studies from Egypt's Luxor Tutankhamun tomb and three experimental studies.Article Citation Count: 8Revenue management with minimax regret negotiations(Pergamon-Elsevıer Scıence Ltd, 2016) Ayvaz Çavdaroğlu, Nur; Kachani, Soulaymane; Maglaras, CostisWe study the dynamic bilateral price negotiations from the perspective of a monopolist seller. We first study the classical static problem with an added uncertainty feature. Next, we review the dynamic negotiation problem, and propose a simple deterministic "fluid" analog. The main emphasis of the paper is in analyzing the relationship of the dynamic negotiation problem and the classical revenue management problems; and expanding the formulation to the case where both the buyer and seller have limited prior information on their counterparty valuation. Our first result shows that if both the seller and buyer are bidding so as to minimize their maximum regret, then it is optimal for them to bid as if the unknown valuation distributions were uniform. Building on this result and the fluid formulation of the dynamic negotiation problem, we characterize the seller's minimum acceptable price at any given point in time. (C) 2015 Elsevier Ltd.

Two studies test a model on the boundary conditions of the linkages across four service industries. The results suggest that whether a resource (i.e. self-efficacy and job autonomy) positively or negatively affects engagement depends on whether (1) a climate is appraised as a challenge or hindrance demand and (2) a climate is deemed a complementary or compensatory resource. Using multi-respondent data from customer service employees and their supervisors in the health care industry Study 1 conceptualizes climate as organizational climate and finds that performance-focused climate strengthens (weakens) the positive effect of self-efficacy (job autonomy) on engagement while service failure recovery climate weakens the positive impact of self-efficacy on engagement. Study 2 generalizes the findings from Study 1 and provides broad support by testing the model using psychological climate in the financial services tourism and hospitality and retailing industries. This study closes with a configuration approach to climate research by discussing when multiple climates can co-exist under different types of resources.Article Citation Count: 16A Search for Missing Links: Specifying the Relationship Between Leader-Member Exchange Differentiation and Service Climate(Sage Publications Inc, 2016) Mengüç, Bülent; Bowen, David E.; Aysuna, Ceyda; Mengüç, BülentWe search for missing links in how the different social exchange relationships employees have with supervisors (i.e. leader-member exchange [LMX] differentiation) affect their unit service climate perceptions. Drawing on a social comparison perspective we propose a model in which the different relationships service employees establish with supervisors negatively impact unit service climate through elevated unit relationship conflict. We further suggest that unit relationship conflict plays a mediating role as customer variability increases. Using data from head nurse-nurse relationships in 56 units of two major hospitals our findings support the proposed linkages as well as reveal that employee perceptions of customer variability strengthen the troublesome positive link between LMX differentiation and unit relationship conflict. The results also indicate that unit relationship conflict mediates the relationship between LMX differentiation and unit service climate when customer variability is high but not low. Our results paint a more nuanced picture of the missing link in the leadership-climate interface by studying the dark side of leadership a perspective that has yet to receive much scholarly attention. Findings reveal that managers who desire to keep relationship conflict in check need to keep LMX differentiation to a minimum especially when customer variability is high compared to low.Article Citation Count: 49Service Employee Burnout and Engagement: The Moderating Role of Power Distance Orientation(Springer, 2016) Mengüç, Bülent; Mengüç, Bülent; Spyropoulou, Stavroula; Wang, FatimaStudies show that service employees are among the most disengaged in the workforce. To better understand service employees' job engagement this study broadens the scope of the job demands-resources (JD-R) model to include power distance orientation (PDO). The inclusion of PDO enriches the JD-R model by providing a key piece of information that has been missing in prior JD-R models: employees' perceptions of the source of job demands (i.e. supervisors) or employees' views of power and hierarchy within the organization. Study 1 uses a survey-based field study to show that employees with a high (compared to low) PDO feel more burnout due to supervisors when they are closely monitored by their supervisors. Study 1 further supports the finding that employees with high (compared to low) PDO feel less disengagement despite burnout due to supervisors. Study 2 using a lab experiment and Study 3 relying on a survey-based field study unveil why these effects were observed. Stress and job satisfaction emerge as mediators that explain the findings from Study 1. Implications of the role of PDO are discussed to improve the current understanding of how job engagement can improve customer service performance.Article Citation Count: 69Unpacking the Relationship Between Sales Control and Salesperson Performance: A Regulatory Fit Perspective(Amer Marketing Assoc, 2018) Mengüç, Bülent; Auh, Seigyoung; Spyropoulou, Stavroula; Mengüç, BülentThe literature examining the effect of sales control on salesperson performance is at best equivocal. To reconcile inconsistencies in empirical findings this research introduces two new types of salesperson learning: exploratory and exploitative learning. Drawing on regulatory focus theory the authors conceptualize exploratory learning as promotion focused and exploitative learning as prevention focused and find that salespeople exhibit both exploratory and exploitative learning though one is used more than the other depending on the type of sales control employed. The results also suggest that the fit between salesperson learning type customer characteristics (i.e. purchase-decision-making complexity) and salesperson characteristics (i.e. preference for sales predictability) is critical to salesperson performance and that salesperson learning mediates the relationship between sales control and salesperson performance (Study 1). Study 2 corroborates the findings using new panel data collected over two waves. The results of this research have important implications for integrating sales control salesperson learning and salesperson performance.Article Citation Count: 71When Does (Mis)Fit in Customer Orientation Matter for Frontline Employees' Job Satisfaction and Performance?(Amer Marketing Assoc, 2016) Mengüç, Bülent; Auh, Seigyoung; Katsikeas, Constantine S.; Jung, Yeon SungThe role of coworkers' customer orientation (CO) in influencing an employee's CO has received sparse attention in the literature. This research serves two purposes. First the study draws on person-group fit theory to develop and test a model of a frontline employee's CO relative to that of his or her coworkers as well as the effects of CO (mis)fit on job satisfaction and service performance through coworker relationship quality. Second the authors propose three workgroup characteristics-group size service climate strength and leader. member exchange differentiation-that they expect to mitigate the (negative) positive effect of employee. coworker CO (mis) fit on coworker relationship quality. Data collected in a multirespondent (i.e. frontline employees and supervisors) longitudinal research design indicate that as group size increases service climate becomes stronger and group leaders develop different exchange relationships with employees the inherently (negative) positive role of employee-coworker CO (mis) fit in influencing coworker relationship quality diminishes. Furthermore coworker relationship quality fully mediates the associations of employee-coworker CO (mis) fit with job satisfaction and service performance. The authors close with a discussion of the theoretical and practical implications of the boundary conditions of CO (mis)fit.
