A service science perspective on business model innovation

Using four basic principles of service science, we systematically explore value-proposition design as one type of business model innovation. Service science combines organization and human understanding with business and technological understanding to categorize and explain service systems, including how they interact and evolve to cocreate value. Our goal is to apply a scientific approach to advance design and innovation in service systems. Our foundation is service-dominant logic, which provides perspective, vocabulary, and assumptions on which to build a theory. Our basic theoretical construct is the service system, entities that are dynamic configurations of four kinds of resources. Our core principles center on the way value is computed within and among entities, how interaction is based on access to resources and their capabilities, and on how value computation and interaction depend on symbol processing and language guided by mutually agreed-to value propositions. In this context, service science can inform and accelerate value-proposition design by systematizing the search for adaptive advantages that improve existing offerings, create new offerings, or reconfigure the value-creating ecosystem.     

The erosion of stable shareholder practice in Japan (“Anteikabunushi Kosaku”)

This study reviews the academic literature to explain internationalisation, mode of entry choice and strategic momentum theory. In this research, we ask whether DiMaggio's theory of isomorphism can be applied to Japan, given the country's Anteikabunushi Kosaku practices and the evidence cited in the literature that suggests that national culture influences managerial work values and Japanese entry mode strategies.We suggest that Japanese management attitudes towards entry mode strategy are changing due to a change in corporate governance policy and competition. In response, we argue that Japan's stable shareholder practice is eroding and that as a result of this erosion, the change observed in institutional behaviour is isomorphic.     

Inferring strategies from observed actions: a nonparametric, binary tree classification approach

This paper introduces a non-parametric binary classification tree approach to inferring unobserved strategies from the observed actions of economic agents. The strategies are in the form of possibly nested if–then statements. We apply our approach to experimental data from the repeated ultimatum game, which was conducted in four different countries by Roth et al. (Am. Econ. Rev. 81 (1991) 1068). We find that strategy inference is consistent with existing inference, provides new explanations for subject behavior, and provides new empirically based hypotheses regarding ultimatum game strategies. We conclude that strategy inference is potentially useful as a complementary method of statistical inference in applied research.     

Progress on XBRL from an Australian perspective

This study examines the progress of XBRL (extensible Business Reporting Language) in the Australian context. XBRL has the potential to be the digital language for data transfer and integration of business systems. The paper describes the nature of XBRL and notes that the Australian Prudential Regulation Authority (APRA) has mandated its use. We review the implications of XBRL, such as audit assurance issues, comparability and real-time reporting, and conclude that XBRL has the potential to enhance financial accounting reporting. What is needed is the completion of the enabling technology, simplification and acceptance.     

Why has unemployment risen in the New South Africa?1

We document the rise in unemployment in South Africa since the transition in 1994. We describe how changes in labour supply interacted with stagnant labour demand to produce unemployment rates that peaked between 2001 and 2003. Meanwhile, compositional changes in employment at the sectoral level widened the gap between the skill‐level of the employed and the unemployed. Using nationally representative panel data, we show that stable unemployment rates mask high individual‐level transition rates in labour market status. Our analysis highlights several key constraints to addressing unemployment in South Africa. We conclude that unemployment is near equilibrium levels and is unlikely to self‐correct without policy intervention.
