  • The value of neighborhood information in prospect selection models investigating the optimal level of granularity

    Van den Poel, Dirk; Baecke, Philippe (2013)
    Within analytical customer relationship management (CRM), customer acquisition models suffer the most from a lack of data quality because the information of potential customers is mostly limited to socio-demographic and lifestyle variables obtained from external data vendors. Particularly in this situation, taking advantage of the spatial correlation between customers can improve the predictive performance of these models. This study compares the predictive performance of an autoregressive and hierarchical technique in an application that identifies potential new customers for 25 products and brands. In addition, this study shows that the predictive improvement can vary significantly depending on the granularity level on which the neighborhoods are composed. Therefore, a model is introduced that simultaneously incorporates multiple levels of granularity resulting in even more accurate predictions.
  • Dynamics of persistent heterogeneity in the global configuration of business services value chains

    Peeters, Carine; Lewin, Arie (2014)
    The paper develops an integrative framework that identifies, describes and links the firm-specific and non-firmspecific factors that co-evolve and mutually influence the changes in configurations of global business services value chains over time. We focus on the heterogeneity of configurations resulting from idiosyncratic choices regarding what processes to unbundle, what activities to locate where, and what control mechanisms to use. Expanding current models and empirical studies in International Business, we argue in particular in favour of a behavioural approach that gives more room to decision makers and the decision making process to explain changing but persistent heterogeneity in ALC configuration (Activity-Location-Control mechanisms) of business Page 44 TUESDAY AIB 2014 Conference Proceedings services global value chains.
  • Fine-slicing global value chains: A protection for proprietary content

    Gooris, Julien; Peeters, Carine (2014)
    This study shows that firms adjust the scope of activities entrusted to foreign services production units to adapt their knowledge and content protection strategy to the availability of strong legal protection or internal control mechanisms. We hypothesize and empirically confirm that, when the above mechanisms are not available, firms use the substitute protection mechanism of “fine-slicing” foreign value chain activities to exploit the complementarities that exist between tasks and reduce misappropriation hazard. We also find a positive moderating effect of firm country-specific experience and content value on the propensity to use the fine-slicing mechanism.
  • Implications of switching from a to-day to a to-week patient scheduling strategy, an application at the UZ Leuven

    Samudra, Michael; Demeulemeester, Erik; Cardoen, Brecht (2013)
    In most hospitals there are some patients who receive surgery later than required. As their health condition can potentially quickly worsen, they are exposed to a health risk. In order to improve the current situation, the lateness of patients has to be, firstly, quantified and, secondly, the responsible mechanism has to be understood, namely the patient scheduling process. We analyzed the percentage of patients being served late in Belgium’s largest hospital, the UZ Leuven. At the hospital, an elective patient is associated with one of five due time intervals within which the patient has to be served. We analyzed the lateness of patients across disciplines using all data from 2012 and 22 ORs. We tried to understand many of the different aspects related to the scheduling process, which knowledge we then included into a simulation model. We investigated from the data: patient arrival patterns, the relation between estimated and realized surgery durations, rescheduling mechanisms and the allocation patterns of emergencies. We also used the model to investigate the effects of switching from the current scheduling practice of assigning surgeries directly to slots (OR and day) to a two-step procedure, where patients are scheduled to a surgery week first and only in a second step to slots. Our results suggest that in case of the two-step procedure it is very important to allow patients with shorter due times to break into the already fixed weekly schedule. Additionally, it is important that in the second step of the scheduling procedure, in the within week scheduling, the due time is considered. We conclude that improving patient scheduling can help to decrease the amount of patients served too late. As a next step, we try to develop a sound scheduling schema, which allows to further decrease the number of patients served to late.
  • How external and internal organizational image impact absenteeism

    De Stobbeleir, Katleen; Caniels, Marjolein; De Clippeleer, Inge; Deprez, Jana; Buyens, Dirk (2014)
    In this study, we investigate how an organization’s employer brand may impact important organizational outcomes. Specifically, using a sample of 59 Belgian companies, we assess the relative importance of employee evaluations and external evaluations in predicting one of the most important HRM concerns in organizations, i.e., absenteeism. Results show that absenteeism decreases both as a function of employees’ views and of outsiders’ views of the organization. Results further show that external perceptions of an employer may be a more important driver of absenteeism than the internal image. Such results highlight the importance of studying organizations’ external image in impacting important employee outcomes.
  • Quantile-based inference for tempered stable distributions

    Veredas, David; Fallahgoul, Hassan; Fabozzi, Frank (2015)
    A simple, fast, and accurate method for the estimation of numerous distributions that belong to the tempered stable class is introduced. The method is based on the Method of Simulated Quantiles and it consists of matching empirical and theoretical functions of quantiles that are informative about the parameters of interest. In the Monte Carlo study we show that MSQ is significantly faster than Maximum Likelihood and the estimates are almost as precise as under MLE. A Value-at-Risk and Expected Shortfall study for 13 years of daily data and for an array of market indexes world-wide shows that the tempered stable estimation with MSQ estimates provides reasonable risk assessments
  • Improving profitability of vehicle routing problems through advanced analytics

    Vercamer, Dauwe; Van den Poel, Dirk; Gendreau, Michel; Baecke, Philippe (2014)
    Based on a real case in door-to-door sales, the study assesses whether revenue predictions coming from transactional data can effectively be used to improve fleet schedules. To do this, two different customer selection models are compared. In the static model, customers are first chosen based on the revenue predictions and then routed through a VNS. The dynamic model uses the predictions in an orienteering problem. Initial results show that the dynamic approach is the most profitable.

  • Delay in filing the financial statements: an empirical analysis among small firms

    Van Caneghem, Tom; Luypaert, Mathieu; Van Uytbergen, Steve (2014)
    We examine delay in filing the financial statements among a large sample of Belgian small firms and find that reporting delay is affected by demand for information (e.g., larger firms tend to report more quickly); specific reporting incentives (e.g., firms tend to delay the disclosure of unfavorable information); and the financial reporting “production process” (e.g., older firms tend to report quickly, which is consistent with a learning curve effect). We note that there is a subsample of early filers, for which the drivers of financial reporting timeliness are found to be different from those identified based on the full sample. Our results further indicate that extremely late filings are associated with lower financial statement quality. Importantly, about 31 percent of the financial statements in our sample are being filed late (i.e., after the legal deadline), but our results suggest that monetary sanctions could be an effective tool in order to ensure compliance with the imposed legal deadline.

  • Breaking silos: A field experiment on relational conflict management in cross-functional teams

    Boros, Smaranda; Van Gorp, Lore; Cardoen, Brecht; Boute, Robert (2016)
    In this paper we investigate how effective conflict management in conflict asymmetry situations impacts the quality of cross-functional management teams’ performance. During a five-day business simulation, we explore the consequences of the relational conflicts and conflict asymmetry experienced by team members. We use two different measures of conflict asymmetry: the traditional group conflict asymmetry measurement of Jehn (1995) and a social networks method. We find that when some team members evoke more conflict than others, this affects the evolution of team dynamics (and ultimately the performance of the team) even more than high levels of conflict altogether; however, the reciprocal emotional understanding between team members (known as group emotional awareness) can mitigate this negative effect and improve the team performance through the appropriate use of conflict management strategies. Since group emotional awareness can be fostered and trained within teams, this is of practical value to improve the performance of cross-functional management teams.
  • How to create trust in multinational corporations? Cross-cultural contingencies in fair strategy process

    Peeters, Carine; Tackx, Koen (2016)
    This paper proposes a conceptual framework and empirical validation to explain how a culturally differentiated application of the procedural justice theory may enhance the functioning of a multinational corporation (MNC). Using original survey data on 103 managers of international corporations who are strongly involved in headquarter-subsidiary relationships, we study how power distance and individualism-collectivism dimensions of culture moderate the relation between the constituents of procedural justice and the trust subsidiaries have in their headquarters. The analysis suggests that for managers originating from a ‘low power distance’ culture, the perception of changeability in the strategy process has much more impact than for managers stemming from a ‘high power distance’ culture. Also, towards managers with a more ‘collectivist’ background, ensuring that expectations and decisions are clear enhances trust more than for managers with a more ‘individualist’ background.
  • Barriers and enablers in the learning process of offshore team members: The role of international assignees

    Peeters, Carine; Duvivier, Florence (2016)
    Through a longitudinal case study of a financial services company offshoring services to Poland, this paper provides insight into the barriers that prevent offshore team members to learn their tasks effectively. Findings also reveal that using expatriates and inpatriates to facilitate the learning process may in fact act as a double edge sword. While helping bridging the distance between onshore and offshore operation, over-parenting by expatriates may create detachment from the part of offshore members who are then less motivated to think independently and learn. And if inpatriation at first helps create social ties between onshore and offshore colleagues - thereby reducing the risk of onshore colleagues hoarding information - and opens careers opportunities that motivate offshore staff to learn; over time it may create frustrations by making offshoring, and in particular associated status and career path differences, visible to all.
