Configuration of innovation and performance in the service industry: evidence from the Taiwanese hotel industry

This study attempts to state some facts about the importance of innovation in the service economy, and especially the hotel industry by classifying the configurations of innovation in Taiwanese hotels, as well as considering the types of innovation configuration that will maximise performance. Technological innovation, organisational innovation, and human capital innovation may be key sources of innovation. This study classified the configurations of innovation based on several innovation activities with two-step cluster analysis. Numerous empirical findings facilitate improved understanding of the relationship between the configurations of innovation and firm performance in the Taiwanese hotel industry.     

Performance measurement and metric manipulation in the public sector

This paper explores the circumstances that influence whether managers in the public services manipulate the measurement information that is used to assess performance; and if they do, what level of deception they might use. The realistic evaluation approach is adopted. A Delphi survey and the collection of critical incidents through interviews are used to identify possible configurations of contexts–mechanisms–outcomes that provide possible explanations of information manipulation. A number of these configurations are discussed. In a later stage of the project these configurations will be further tested through another Delphi survey, with the intention of developing proposals for improved governance of performance measurement systems in the public services.     

A taxonomy of small- and medium-sized international family firms

This study develops a taxonomy of small- and medium-sized family firms that internationalise and discusses the different configurations of these firms based on firm culture (in terms of organisational orientations), firm strategy (in terms of differentiation, cost leadership and marketing standardisation) and firm structure (in terms of integration, centralisation and specialisation). Although the literature on international family firms has highlighted the significant role of organisational culture in firm internationalisation, the strategies and structures of international family firms and their consequences for performance have been disregarded. To examine the interplay of international family firm culture, strategy and structure, we employ a quantitative taxonomic approach that is rooted in configurational theory, analysing 504 Germany-based small- and medium-sized family firms. Different combinations of strategy, structure and culture result in different configurations of family firms and different levels of non-domestic performance. In considering these configurations, we aim to determine which combinations of strategies, structures and firm orientations are primarily applied by international family firms and whether these organisational configurations are successful. Our empirical findings suggest that there are four groups of firms: Domestic-Focussed Traditionalists, Global Standardisers, Multinational Adapters and Transnational Entrepreneurs. These configurations are clearly distinctive in terms of their structure, orientations and performance but differ less in terms of their strategies. Superior international (i.e. non-domestic) performance tends to be driven by a decentralised entrepreneurial approach.     

Network configuration and innovation success: An empirical analysis in German high-tech industries

Based on the assumption that intensity and structure are the most important dimensions of a firm's technological network, the authors identity seven different types of technology-oriented network configurations. Drawing upon a database of 321 high-tech companies, they show that innovation success is significantly correlated with a firm's technological network. Product and process innovations are shown to demand different types of network configurations.     

National institutional systems,foreign ownership and firm performance: The case of understudied countries

We analyse the relationship between institutional systems (configurations of countries with similar institutional characteristics) and firm performance. We use a large sample of firms from understudied countries to explore whether the performance impact of these configurations is the same (“equifinality”), whether this holds across different measures of firm performance (“Tversky effect”), and whether some institutional configurations better support foreign-owned firms. We find that it is possible to rank institutional systems according to their impact on firm performance, but the ranking differs according to the performance measure. Although foreign ownership on average confers performance advantages, the magnitude of the impact depends on the configuration. Our findings contribute to the understanding of the importance of institutional similarities across countries, and to the implications of these similarities for the theory of the MNE.     

A configural framework of practice change for B corporations

There is increasing scholarly attention toward understanding how enterprises seeking prosocial impact organize their practices. However, this research has primarily explained changes in isolated practices and has not fully explored the mechanisms for such changes. This omission is relevant for social entrepreneurship scholars who seek to better understand how practices operate not simply internally but can effect a positive impact. We address this omission by drawing from a unique longitudinal dataset – assessment scores of enterprises seeking to be certified and recertified as B Corporations (B Corps). We also conducted 24 interviews with B Corp leaders, B Lab staff, and venture fund managers. We found that B Corps shifted their practice configurations as they underwent assessment and reassessment for certification. We also found that exogenous factors such as size and sector, and endogenous factors such as the nature of practices explained shifts in practice configurations. Our contribution is twofold. First, we test deductive claims that social enterprises re-organize for impact. We show that enterprises update their practice configurations over time. Second, we propose an inductively derived theoretical framework with three building blocks: affordability, interpretability, and social referents to explain the shifts in practice configurations.

General theory of cultures' consequences on international tourism behavior

National cultures represent complex configurations of values rather than a collection of distinct individual value dimensions. This presentation applies qualitative (configural) comparative analysis (QCA/CCA) to consider how cultural recipes—complex configurations of national culture affect international experiential behavior. The QCA method focuses on considering asymmetric relationships—reporting conditions that are sufficient (but not necessary) to cause an outcome condition (e.g., high-dollar expenditures). Using measures of consistency and coverage the QCA method provides estimates of how well alternative configurative models explain behavior rather than relying on symmetric data analysis methods (correlations and multiple regression). The method includes the use of Hofstede's country value scores with data from group-level and sub-group (by age and prior consumption experience) exit survey responses of visitors to Australia from 14 Asian, European, and North American countries. The analysis applies QCA software (www.fsQCA.com) and the presentation includes XY plots of country-level value configurations and group-level consumption for total visit expenditures, length of visit, shopping behavior, and group touring behavior.

Socioemotional Wealth and Innovativeness in Small‐ and Medium‐Sized Family Enterprises: A Configuration Approach

What makes small‐ and medium‐sized family firms (family SMEs) innovative? Some family firm dynamics promote, yet others hinder innovation. It remains unclear whether combinations of family firm dynamics increase innovativeness. Our configurational perspective of socioemotional wealth (SEW) unravels determinants of family SMEs' innovativeness. We conduct a fuzzy set qualitative comparative analysis with 452 Swiss family SMEs. We categorize SEW dimensions into configurations of necessary and sufficient conditions. We contribute to theory on family SMEs' innovativeness because we reveal that the interplay of SEW dimensions leads to innovativeness. This offers practitioners a better framework to choose between SEW configurations.
