    • Motivated consumer innovativeness: Concept and measurement, and validation

      Vandecasteele, Bert; Geuens, Maggie (International Journal of Research in Marketing, 2010)
      Existing consumer innovativeness scales ignore the multitude of motivation sources of buying innovations. The objective of this paper is to incorporate different motivations into a multi-dimensional innovativeness scale to better account for the consumer–product relationship. An extensive literature review and five studies (with about 2600 respondents in total) indicate that four types of motivation underlie consumer innovativeness: functional, hedonic, social, and cognitive. The proposed 20-item four-dimensional Motivated Consumer Innovativeness (MCI) scale proves to be reliable and internally valid and does not seem to suffer from social desirability bias. Moreover, the results of the studies indicate the predictive validity of every MCI dimension. This new scale proves to measure more than existing consumer innovativeness scales; the different MCI dimensions predict innovative purchase intentions better than both traditional and recently developed innovativeness scales, and they disprove the general consensus that older people are always significantly less innovative than younger people. This MCI scale can serve as a tool for future research on efficiently and effectively segmenting and targeting (motivated innovative) consumers.

    • Multi-mode schedule optimisation for incentivised projects

      Kerkhove, Louis-Philippe; Vanhoucke, Mario (Computers and Industrial Engineering, 2020)
      This research presents a novel quantitative methodology to optimise the scheduling of subcontracted projects from the perspective of the contractor. Specifically, the scenario where the contractor’s remuneration is performance dependent is investigated. Based on the incentive methodology introduced by Kerkhove and Vanhoucke (2016), a novel mixed integer programming formulation as well as a greedy local search heuristic to solve the contractor’s problem are presented and tested in a computational experiment. For this experiment, a database containing 3,150 contract-project combinations with diverse structures has been created. The results from this experiment demonstrate the efficiency of the MIP formulation even for larger problem instances, as well as the influence of the project and contract structure on the contractor’s earnings.
    • Multicountry Multifactor Tests of the Factor Abundance Theory

      Bowen, Harry; Learner, E.; Sveikauskas, Leo (American Economic Review, 1987)
      Conceptually correct tests are performed of the Heckscher-Ohlin proposition that trade in commodities can be explained in terms of an interaction between factor input requirements and factor endowments. An exact specification of this interaction in a multicountry, multicommodity, multifactor world is derived in the form of the Heckscher-Ohlin-Vanek (H-O-V) theorem. The relationships are tested using data on the 367-order US input-output tables for 1967 and the 1967 trade and the 1966 supply of 12 resources for 27 countries. The Leontief-type sign and rank propositions, whether tested across countries or across factors, generally are not supported. The hypothesis that the H-O-V equations are exact also is not supported by the data. The data indicate errors in measurement in both trade and national factor supplies and favor the hypothesis of neutral technological differences across countries. The H-O-V equations are rejected in favor of weaker models that permit technological differences and measurement errors.
    • Multivariate Hill Estimators

      Dominicy, Yves; Ilmonen, Pauliina; Veredas, David (International Statistical Review, 2017)
      We propose two classes of semi-parametric estimators for the tail index of a regular varying elliptical random vector. The first one is based on the distance between a tail probability contour and the observations outside this contour. We denote it as the class of separating estimators. The second one is based on the norm of an arbitrary order. We denote it as the class of angular estimators. We show the asymptotic properties and the finite sample performances of both classes. We also illustrate the separating estimators with an empirical application to 21 worldwide financial market indexes.

    • Nearest neighbour propensity score matching and bootstrapping for estimating binary patient response in oncology: A Monte Carlo simulation

      Geldof, Tine; Dusan, Popovic; Van Damme, Nancy; Huys, Isabelle; Van Dyck, Walter (Scientific Reports: A Nature Research Journal, 2020)
      Nearest Neighbour (NN) propensity score (PS) matching methods are commonly used in pharmacoepidemiology to estimate treatment response using observational data. Unfortunately, there is limited evidence on the optimal approach for accurately estimating binary treatment response and, more so, to estimate its variance. Bootstrapping, although commonly used to accurately estimate variance, is rarely used together with PS matching. In this Monte Carlo simulation-based study, we examined the performance of bootstrapping used in conjunction with PS matching, as opposed to diferent NN matching techniques, on a simulated dataset exhibiting varying levels of real world complexity. Thus, an experimental design was set up that independently varied the proportion of patients treated, the proportion of outcomes censored and the amount of PS matches used. Simulation results were externally validated on a real observational dataset obtained from the Belgian Cancer Registry. We found all investigated PS methods to be stable and concordant, with k-NN matching to be optimally dealing with the censoring problem, typically present in chronic cancer-related datasets, whilst being the least computationally expensive. In contrast, bootstrapping used in conjunction with PS matching, being the most computationally expensive, only showed superior results in small patient populations with long-term largely unobserved treatment efects.

    • Negatieve feedback leidt zelden tot verbetering

      Van Steerthem, Angie (HR Magazine, 2019)
      Kritische beoordelingen van collega's zetten medewerkers ertoe aan hun rol aan te passen, zodat ze meer kunnen samenwerken met wie hen positievere beoordelingen geeft. Hoe negatiever de feedback, hoe verder de werknemers gaan om nieuwe netwerken te smeden. Dat blijkt uit onderzoek van Paul Green, doctoraatsstudent aan de Harvard Business School en twee van zijn collega’s. Het onderzoek werd onder meer gevoerd in een bedrijf dat een transparant peerreviewproces hanteert en de medewerkers toelaat hun job voor een stuk zelf vorm te geven.
