• Job insecurity, knowledge hiding, and team outcomes

      Huang, Guohua; Lee, Cynthia; De Stobbeleir, Katleen; Wang, Li (2019)
      Job insecurity – the threat to the continuity and stability of one’s employment – is an increasingly pervasive issue facing the vast majority of employees. There has been much knowledge accumulated about antecedent and outcomes of job insecurity. However, further advancements in our theoretical and empirical approaches can help us to better understand the consequences, processes, and boundary conditions of job insecurity itself, job insecurity change, and job insecurity climate. With four papers using a moderated mediation model and one paper using a dynamic, mediated model, the current symposium contributes to our understanding of job insecurity by: (1) exploring why and when job insecurity is associated with employee health outcomes and proactive behaviors, (2) examining sources and consequences of job insecurity change when significant organizational changes were taking place, and (3) identifying mechanisms and boundary conditions in the relationship between job insecurity climate at the team level and team outcomes. By showcasing five empirical papers, this symposium focuses on identifying and exploring novel moderators and mediators in the job insecurity process to enrich our understanding of job insecurity, job insecurity change, and job insecurity climate. Together, the combined contributions of these papers add to our understanding of job insecurity as a between-person, within-person and/or multilevel process and illuminate future avenues for research within the field.

    • Johnson Gear - Part D: Managing supply chain risk: flexibility to a major customer - teaching note

      Vereecke, Ann; Boeykens, Danny (2012)
      Although e-commerce has become a common basis for business transactions in most markets, other elements of e-business are not as widely used yet. This paper extends and operationalizes a previously developed e-business process model by Basu and Muylle (2007). Specifically, it presents evaluation measures for each process and an instrument based on those measures, and describes an effective approach to assess firms’ e-business capabilities. The assessment approach is illustrated using data from a diverse collection of firms in the Flanders region of Belgium. This is followed by an illustration of how such assessments can assist firms in identifying e-business initiatives in line with strategic and market priorities, using a subset of the firms as examples.

    • The joint replenishment problem: Optimal policy and exact evaluation methody

      Creemers, Stefan; Boute, Robert (European Journal of Operational Research, 2022)
      We propose a new method to evaluate any stationary joint replenishment policy under compound Poisson demand. The method makes use of an embedded Markov chain that only considers the state of the system after an order is placed. The resulting state space reduction allows exact analysis of instances that until now could only be evaluated using approximation procedures. In addition, the size of the state space is not affected if we include nonzero lead times, backlog, and lost sales. We characterize the optimal joint replenishment policy, and use these characteristics to develop a greedy-optimal algorithm that generalizes the can-order policy, a well-known family in the class of joint replenishment policies. We numerically show that this generalized can-order policy only marginally improves the best conventional can-order policy. For sizeable systems with multiple items, the latter can now be found using our exact embedded Markov-chain method. Finally, we use our method to improve and extend the well-known decomposition approach.
    • A joint replenishment production-inventory model as an MMAP[K]/PH[K]/1 queue

      Noblesse, Ann M.; Sonenberg, Nikki; Boute, Robert; Lambrecht, Marc R.; Van Houdt, Benny (Stochastic Models, 2022)
      In this paper we analyse a continuous review finite capacity production-inventory system with two products in inventory. With stochastic order quantities and time between orders, the model reflects a supply chain that operates in an environment with high levels of volatility. The inventory is replenished using an independent order-up-to (s, S) policy or a can-order (s, c, S) joint replenishment policy in which the endogenously determined lead times drive the parameters of the replenishment policy. The production facility is modelled as a multi-type MMAP[K]/PH[K]/1 queue in which there are K possible inventory positions when the order is placed and the age process of the busy queue has matrix-exponential distribution. We characterize the system and determine the steady state distribution using matrix analytic methods. Using numerical methods we obtain the inventory parameters that minimize the total ordering and inventory related costs. We present numerical comparisons of independent and joint replenishment policies with varying lead times, order quantities, and cost reductions. We further demonstrate the interplay between the two products in terms of lead times, order quantities and costs.

    • Judging Factor Abundance

      Bowen, Harry; Sveikauskas, Leo (The Quarterly Journal of Economics, 1992)
      Recent theory casts doubt on the frequently used interindustry regression method of inferring a country's abundant factors. The empirical importance of these theoretical qualifications is examined by comparing regression-derived estimates of factor abundance with both revealed and actual factor abundances for 35 countries and 12 resources. The theoretical importance of trade imbalances for the reliability of the regression estimates is demonstrated, and a theoretically consistent trade imbalance correction is proposed and implemented. The results indicate that, despite valid theoretical concerns, the regression estimates are generally reliable indicators of revealed factor abundance. Therefore, the innumerable regression studies conducted over the past 30 years can be considered to provide reliable evidence concerning the validity of the factor abundance theory.
