• Psychological empowerment in the workplace: reviewing the empowerment effects on critical work outcomes

      Dewettinck, Koen; Singh, Jagdip; Buyens, Dirk (2003)
      This paper reviews theory and empirical findings on the effects of empowerment in the workplace. Data from existing studies is used to assess the effects of the four empowerment dimensions on affective and behavioral employee responses. Data is reanalyzed using hierarchical regression analysis. Confirming growing skepticism among practitioners and academics, this study indicates that empowerment practices result in more satisfied and committed, but not necessarily better performing employees. Furthermore, it is shown that there is a differential impact of the distinct empowerment dimensions on employee performance levels. Theoretical and practical implications are discussed.

    • Public procurement of innovation through increased startup participation: The case of Digipolis

      De Coninck, Ben; Viaene, Stijn; Leysen, Jan (2018)
      Previous research has identified numerous obstacles that hinder the efficient procurement of innovation by the public sector. This paper introduces the case of Digipolis – the public ICT service provider of the City of Antwerp in Belgium. In 2015, the company implemented a comprehensive overhaul of its procurement strategy centered around 3 key components: a flexible procurement process, a community built around Digital Antwerp, and a challenge-oriented company culture. The case adopts a holistic perspective on the implementation of innovation procurement in a local public sector organization, and investigates the specific conditions and mechanisms that allowed to leverage the Antwerp startup community in order to increase the number of purchased innovative solutions. The case also sheds light on how public procurement of innovation can lead to knowledge-intensive entrepreneurship – an area that is still largely undiscovered.

    • Purchasing-driven sales: Matching sales strategies to the evolution of the purchasing function

      Paesbrugghe, Bert; Rangarajan, Deva; Sharma, Arun; Syam, Niladri; Jha, Subhash (Industrial Marketing Management, 2017)
      The personal selling field has witnessed the emergence of various sales strategies, including relationship, value, key account, and solution selling. Despite claims about their effectiveness, recent work challenges the relevance of existing sales strategies across buying contexts. Specifically, emerging sales strategies often focus on the user in the customer organization, without being explicitly aligned with the increasingly important purchasing function. To define the critical role of the purchasing function for sales effectiveness, this study collects data from 32 firms in two markets, their purchasing departments reveal four stages of purchasing evolution: passive (price focused), independent (cost-focused), supportive (solution/innovation focused), and integrative (strategy focused). The research demonstrates that each stage of purchasing evolution then requires distinct sales strategies by selling firms and any mismatch of purchasing evolution and sales strategy may be detrimental to sales. This novel view and the supported findings offers several implications for both research and practice.

    • Quality and pricing decisions in production/inventory systems

      Jalali, Hamed; Raïsa, Carmen; Van Nieuwenhuyse, Inneke; Boute, Robert (European Journal of Operational Research, 2019)
      In this article, we consider the impact of finite production capacity on the optimal quality and pricing decisions of a make-to-stock manufacturer. Products are differentiated along a quality index; depending on the price and quality levels of the products offered, customers decide to either buy a given product, or not to buy at all. We show that, assuming fixed exogenous lead times and normally distributed product demands, the optimal solution has a simple structure (this is referred to as the load-independent system). Using numerical experiments, we show that with limited production capacity (which implies load-dependent lead times) the manufacturer may have an incentive to limit the quality offered to customers, and to decrease market coverage, especially in settings where higher product quality leads to higher congestion in production. Our findings reveal that the simple solution assuming load-independent lead times is suboptimal, resulting in a profit loss; yet, this profit loss can be mitigated by constraining the system utilization when deciding on quality and price levels. Our results highlight the importance of the relationship between marketing decisions and load-dependent production lead times.
    • Quantify-me: consumer acceptance of wearable self-tracking devices

      Pfeiffer, Jurij; von Entreß-Fürsteneck, Matthias; Urbach, Nils; Buchwald, Arne (2016)
      The usage of wearable self-tracking technology has recently emerged as a new big trend in lifestyle and personal optimization in terms of health, fitness and well-being. Currently, only little is known about why people plan or start using such devices. Thus, in our research project, we aim at answering the question of what drives the usage intention of wearable self-tracking technology. Therefore, based on established technology acceptance theories, we deductively develop an acceptance model for wearable self-tracking technologies which sheds light on the pre-adoption criteria of such devices. We validate our proposed model by means of structural equation modeling using empirical data collected in a survey among 206 potential users. Our study identifies perceived usefulness, perceived enjoyment, social influ-ence, trust, personal innovativeness, and perceived support of well-being as the strongest drivers for the intention to use wearable self-tracking technologies. By accounting for the influence of the demographic factors age and gender, we provide a further refined picture.
    • 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
    • Quantile-based inference for tempered stable distributions

      Fabozzi, Frank; Fallahgoul, Hassan; Veredas, David (Computational Economics, 2019)
      If the closed-form formula for the probability density function is not available, implementing the maximum likelihood estimation is challenging. We introduce a simple, fast, and accurate way for the estimation of numerous distributions that belong to the class of tempered stable probability distributions. Estimation is based on the Method of Simulated Quantiles (Dominicy and Veredas (2013)). MSQ 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 MLE. A Value at Risk study using 13 years of daily returns from 21 world-wide market indexes shows that MSQ estimates provide as good risk assessments as with MLE.
