A NOTE ON SEMIPARAMETRIC ESTIMATION OF FINITE MIXTURES OF DISCRETE CHOICE MODELS WITH APPLICATION TO GAME THEORETIC MODELS*

We view a game abstractly as a semiparametric mixture distribution and study the semiparametric efficiency bound of this model. Our results suggest that a key issue for inference is the number of equilibria compared to the number of outcomes. If the number of equilibria is sufficiently large compared to the number of outcomes, root‐n consistent estimation of the model will not be possible. We also provide a simple estimator in the case when the efficiency bound is strictly above zero.     

A multivariate Poisson mixture model for marketing applications

This paper describes a multivariate Poisson mixture model for clustering supermarket shoppers based on their purchase frequency in a set of product categories. The multivariate nature of the model accounts for cross-selling effects between the purchases made in different product categories. However, for computational reasons, most multivariate approaches limit the covariance structure by including just one common interaction term, or by not including any covariance at all. Although this reduces the number of parameters significantly, it is often too simplistic as typically multiple interactions exist on different levels. This paper proposes a theoretically more complete variance/covariance structure of the multivariate Poisson model, based on domain knowledge or preliminary statistical analysis of significant purchase interaction effects in the data. Consequently, the model does not contain more parameters than necessary, whilst still accounting for the existing covariance in the data. Practically, retail category managers can use the model to devise customized merchandising strategies.

A Method to Evaluate Mode Effects on the Mean and Variance of a Continuous Variable in Mixed‐Mode Surveys

Les enquêtes à mode de collecte mixte, dans lesquelles le choix du mode de réponse est laissé aux personnes interrogées, sont de plus en plus répandues. Cette possibilité du choix du mode de réponse peut induire une confusion entre deux sortes d'effets : les effets de sélection et les effets de mesure. L'estimation séparée de ces deux effets est impossible à partir des seules données d'une enquête à mode de collecte mixte. Dans cet article, nous montrons comment la même estimation devient possible à partir d'une comparaison entre les résultats d'une enquête à mode de collecte mixte et ceux d'un enquête à mode de collecte unique basées sur le même questionnaire. La méthode que nous proposons permet d'estimer l'effet du mode de réponse sur la moyenne et la variance d'une variable de réponse continue. Elle est illustrée par l'estimation des effets du mode de réponse sur six questions relatives aux opinions vis‐à‐vis des enquêtes.     

The changing role of guanxi in influencing the development of entrepreneurial companies: a case study of the emergence of pharmaceutical companies in China

“Guanxi” is a term in Chinese referring to the reciprocal nature of interpersonal relationships. Its attributes, which are specific to Chinese culture, have been the focus of recent literature. Whereas the impact of guanxi seems to be quite similar to that of general relationships, ties or connections, it is characterized by a number of different dimensions. In this paper, we studied 44 entrepreneurial companies in the pharmaceutical industry in China to examine these attributes in greater detail. We use a system dynamics model to simulate the influence of various guanxi variables – the strength, scale and structure of guanxi – on the development of entrepreneurial companies.     

Network ties and entrepreneurial orientation: Innovative performance of SMEs in a developing country

This study investigates the role of intra-cluster ties, extra-cluster ties, and entrepreneurial orientation in shaping firms’ innovative performance. We conduct our analysis on a primary data set of 120 small and medium enterprises located in the Cibaduyut footwear-manufacturing cluster, Indonesia. We explore the effectiveness of knowledge acquisition through intra-cluster ties and extra-cluster ties on innovative performance. We find that extra-cluster ties mediate the relationship between proactiveness and innovative performance. Also, a combination of high extra-cluster ties and risk taking exert a positive impact on innovative performance. Surprisingly, we find that risk taking negatively moderates the influence of intra-cluster ties on innovative performance. Over-reliance on within-cluster knowledge sharing may result in the diffusion of redundant knowledge rather than making new knowledge available to the firm. Overall, our findings point to the synergistic effects of entrepreneurial orientation and extra-cluster ties on innovative performance.     

Sustainable Development and Well-Being: A Philosophical Challenge

This paper aims at gaining a better understanding of the inherent paradoxes within sustainability discourses by investigating its basic assumptions. Drawing on a study of the metaphoric references operative in moral language, we reveal the predominance of the ‘well-being = wealth’ construct, which may explain the dominance of the ‘business case’ cognitive frame in sustainability discourses (Hahn et al. in Acad Manag Rev 4015:18–42, 2015a). We incorporate economic well-being variables within a philosophical model of becoming well (Küpers in Cult Organ 11(3):221–231, 2005), highlighting the way in which these variables consistently articulate a combination of ‘objective’ and ‘subjective’ concerns. We then compare this broad understanding of well-being with the metaphors operative in the sustainable development discourse and argue that the sustainability discourse has fallen prey to an overemphasis on the ‘business case’. We proceed to draw on Georges Bataille to challenge the predominance of these value priorities and to explore which mindshifts are required to develop a more comprehensive understanding of what is needed to enable ‘sustainable development’.     

Customer demotion in hierarchical loyalty programmes

Hierarchical loyalty programmes are popular in many service industries, as a means to tie customers to the company and improve customer relationships. In these programmes, customers obtain more benefits if they spent more but are demoted if they spent less. This study focuses on demotion and suggests that customer demotion can have an asymmetrical negative effect on customers' trust, commitment, and loyalty. The effect appears strongest for demoted customers with an external locus of causality. An experimental study also shows that customer loyalty is lower for demoted customers than for customers who were never elevated.
