Ethical Transparency and Economic Medicalization

This article introduces the concept of economic medicalization where non-medical problems are transformed into medical problems in order to achieve the objective of corporate shareholder wealth maximization. Following an overview of the differences in ethical norms applicable to medical ethics and business ethics, the economic medicalization of medical research practice and publication is examined in some detail. This motivates a general discussion of the problems involved in the ethical approval process for medical research that balances the interests of both business and government in the market for medical products and services.     

Price Run-up in Housing Markets,Access to Bank Lending and House Prices in Korea

This paper studies the causal relationship between house prices and the access to bank lending in Kangnam, the hottest submarket in Seoul and four ‘cold’ markets which have shown relatively modest price increases. In response to the rapid escalation of house prices in Seoul, primarily in Kangnam in recent years, the Korean government implemented a number of policies to stabilize house prices. In particular, it introduced more strict limits on loan-to-value ratio and debt-to-income ratio as part of the mortgage loan qualification process in order to restrict the availability of bank lending for the housing market. The short-run influence of the bank lending on the apartment prices is clearly present in ‘cold’ markets, while it is not in Kangnam, the ‘hot’ market, even though the long-run influence is stronger in Kangnam than in the other markets. This result holds for the entire sample period (1999–2006) as well as for the subperiods before and after the introduction of lending restrictions in August, 2005. It also holds for Kangnam and Kangbuk for an extended period of 1988 to 2006. Our results suggest that in the short run the lending restriction may cause a disruption in untargeted housing markets while it has little influence on the apartment prices in the targeted market. We also find that banks have adjusted the bank lending in response to changes in the house prices in Kangnam as well as in the other markets.     

Co-Evolution: Law and Institutions in International Ethics Research

Despite the importance of the co-evolution approach in various branches of research, such as strategy, organisation theory, complexity, population ecology, technology and innovation (Lewin et al., 1999; March, 1991), co-evolution has been relatively neglected in international business and ethics research (Madhok and Phene, 2001). The purpose of this article is to show how co-evolution theory provides a theoretical framework within which some issues of ethics research are addressed. Our analysis is in the context of the contrasts between business systems (North, 1990), and in particular the distinction between informal systems and those systems where institutions are formalised in law. This complements the growing research on comparative corporate governance and capitalisms (Chandler and Hikino, 1990; Choi et al., 1999; Whitley, 1994). The synthesis of co-evolution and analysis of divergent institutional environments in ethics research can also complement the globalisation and MNE approaches to international business research.     

Empirical Evaluation of Fair Use Flat Rate Strategies for Mobile Internet

The fair use flat rate is a promising tariff concept for the mobile telecommunication industry. Similar to classical flat rates it allows unlimited usage at a fixed monthly fee. Contrary to classical flat rates it limits the access speed once a certain usage threshold is exceeded. Due to the current global roll-out of the LTE (Long Term Evolution) technology and the related economic changes for telecommunication providers, the application of fair use flat rates needs a reassessment. We therefore propose a simulation model to evaluate different pricing strategies and their contribution margin impact. The key input element of the model is provided by so-called discrete choice experiments that allow the estimation of customer preferences.     

The Integration of Mortgage and Capital Markets in Emerging Economies—Evidence from South Africa

Integration of the capital and mortgage markets is an important step in moving emerging countries toward full economic development. With data from South Africa, this research examines the incremental contribution of deregulation and the secondary mortgage market to the integration between the mortgage and capital markets. With deregulation occurring in the early 1980s, the results indicate that the two markets were fully integrated prior to 2001 when a secondary mortgage market was introduced in South Africa. However, we also find that the introduction of the secondary mortgage market has significantly reduced constraints on the supply of mortgage credit.     

Process innovations and firm productivity growth

This article analyses the effect of process innovations on firm total factor productivity growth, explicitly considering the impact of firm size on the nature of this relationship. In particular, we analyse whether firm size affects the life span of the impact of process innovations on productivity growth. The data are drawn from a Spanish survey of manufacturing firms over the period 1991–1998. We use a fully non-parametric methodology based on the concept of stochastic dominance. Our results show that the implementation of process innovations produces an extra productivity growth both for large and small firms. However, this productivity growth is more persistent for large than for small firms.     

A virtual voyage through 3D structures generated by chaotic mixing of magmas and numerical simulations: a new approach for understanding spatial and temporal complexity of magma dynamics

In this contribution, we present a virtual voyage through 3D structures generated by chaotic mixing of magmas and numerical simulations with the aim to highlight the power of 3D representations in the understanding of this geological phenomenon. In particular, samples of mixed juveniles from Salina island (Southern Italy) are reconstructed in 3D by serial lapping and digital montage and numerical simulations are performed by using a 3D chaotic dynamical system. Natural and simulated magma mixing structures are visualized by using several multimedia tools including animations and “virtual reality” models. It is shown that magma interaction processes can generate large spatial and temporal compositional heterogeneities in magmatic systems. The same topological structures are observed in both 3D reconstructed rock samples and chaotic numerical simulations, indicating that the mixing of magmas is governed by chaotic dynamics. The use of 3D multimedia models gives the opportunity to penetrate into magma mixing structures and to understand their significance in the context of magma dynamics. Such an approach is very powerful since multimedia tools can strongly capture the attention of the reader bringing him/her into an interactive and memorable geological experience.     

Social capital and entrepreneurial process

The paper examines the relationship between social capital and entrepreneurial engagement of individuals in 35 nations from Europe and Asia. To the best of our knowledge, this is the first empirical research that attempts to investigate the influence of three-dimensional social capital concept – trust, networks and norms – on three stages of entrepreneurial process – preference, trial and success – using such large and comprehensive cross-sectional micro data. In general, we find that all three dimensions of social capital matter in the entrepreneurship context, albeit differently. They become beneficial in different ways and at different stages of entrepreneurial involvement. For example, among trust variables, institutional trust in general, and trust in business-oriented and business-supporting actors in particular, exert significant positive effect on entrepreneurial process. Individuals with formal membership in professional associations are more likely to perceive entrepreneurial opportunities, while some close or strong-tie networks might prevent them from progressing in the entrepreneurship ladder. Finally, individual level civic norms appear to be negatively associated with early-stage entrepreneurship, while the success in becoming an entrepreneur is not found to be bound by people’s civic norms.
