Risk premium,macroeconomic shocks,and information technology: an empirical analysis

This study empirically identifies the impact of various macroeconomic factors on the default risk premium. Using monthly data for the period 1970–2010 for the US, our estimations indicate that the monetary policy aggregates, risk-free interest rate, term structure of interest rates, inflation, and the state of the business cycle influence the risk premium. The results also provide some evidence in support of the hypothesis that the development of information technology has had a decreasing impact on the risk premium. As expected, various financial crises have had substantial and long-lasting effects on the premium. The results suggest that the direct impact of the subprime crisis and Lehman’s collapse on the risk premium was as large as two and a half percentage-points for a sustainable period. Foreign financial crises, in turn, have lowered the risk premium in the US market, suggesting a flight-to-safety phenomenon.     

Set-valued solution concepts using interval-type payoffs for interval games

Uncertainty is a daily presence in the real world. It affects our decision making and may have influence on cooperation. Often uncertainty is so severe that we can only predict some upper and lower bounds for the outcome of our actions, i.e., payoffs lie in some intervals. A suitable game theoretic model to support decision making in collaborative situations with interval data is that of cooperative interval games. Solution concepts that associate with each cooperative interval game sets of interval allocations with appealing properties provide a natural way to capture the uncertainty of coalition values into the players’ payoffs. In this paper, some set-valued solution concepts using interval payoffs, namely the interval core, the interval dominance core and the interval stable sets for cooperative interval games, are introduced and studied. The main results contained in the paper are a necessary and sufficient condition for the non-emptiness of the interval core of a cooperative interval game and the relations between the interval core, the interval dominance core and the interval stable sets of such a game.     

A note on ‘Corporate Social Responsibility and Marketing Channel Coordination’

Goering (2012) works on a bilateral monopoly with perfect marketing channel coordination to analyze the effects of corporate social responsibility. He starts the analysis of a bilateral monopoly with socially concerned firms where either the manufacturer or the retailer is additionally to its profit interested in a share of consumer surplus. In this short note, we extend this analysis and study the case where both firms are socially concerned. As a result, we enlarge the analysis started by Goering (2012) and get further interesting insights into a bilateral monopoly with corporate social responsibility. First, we are able to summarize ‘Proposition 1’ and ‘Proposition 4’ into a common one and figure out the circumstances when the wholesale price fixed by the manufacturer is below marginal costs. Second, we explain analytically the findings from ‘Proposition 3’ and ‘Proposition 6’. We point out the model's key assumption – the perfectly coordinated marketing channel – as the driver of the results and the reason for the equilibrium results' independence from retailer's social concern.     

Hilfe aus Osteuropa – legal oder illegal?

In solchen F?llen müssen Unterstützungsm?glichkeiten und Alternativen gefunden werden. Nicht selten wird dabei auf Hilfen aus Osteuropa zurückgegriffen. Doch was ist erlaubt?     

A corporate model of sustainable business practices: An ethical perspective

This paper considers contemporary business practice and its sustainable performance from the view of stakeholders and their perceived value. A company has responsibilities and commitments to many different internal and external stakeholders in the marketplace and society. This view underlines the need for organizations to, not only provide value, but do so in a sustainable and socially responsible manner. A model is developed based on five, separate but interconnected, elements. The model is iterative and acknowledges its elementary state, suggesting further development and refinement in the field of sustainable business practices from an ethical perspective.     

Innovation,networking and the new industrial clusters: the characteristics of networks and local innovation capabilities in the Turkish industrial clusters

Elaborating on the literature on industrial districts, this paper suggests that innovation and networking are the two key issues, which provide the new generation industrial clusters’ competitive capacity in the globalization process. The paper presents the findings on the innovative and networking capabilities of the three important industrial clusters of Turkey based on the data collected from the sample firms in each of these industrial clusters through in-depth interviews. The findings clearly show the importance of local and national networking as well as global linkages and confirm the positive relation between intensity of local networking and innovativeness. Moreover, the paper provides evidence that firms within global networks have higher numbers of innovations than firms with higher intensity of locally embedded linkages.     

Online monitoring and assessment of emerging risk in conventional industrial plants: possible way to implement integrated risk management approach and KPI’s

Existing methodologies and practices do not provide enough possibility for online monitoring and assessment of emerging risks occurring as a result of a change in technology, product, operating conditions, as well as in organization of activities in conventional industrial plants. Typical today’s off and online methods and corresponding software packages are used as risk assessment methods, while various risk aspects (such as: process risks, process equipment integrity risks, organizational risks, and health and environmental risks) are being assessed and treated independently. However, it is clear that risk assessment and making decisions in line with that has to be based on information collected from different (independent) sources in online mode. Also, the fact that additional risks in operations may occur due to unexpected changes in technology, accidents or unexpected process equipment degradation should be taken into account. When monitoring and process management systems are being designed and developed, only the process aspect and process risk are usually analyzed, while other risk aspects are not taken into account (like health and environmental risks). A new approach, to be presented in this paper, provides a possibility of online monitoring and assessment of risks (e.g. in petrochemical industry, power industry, etc.).     

The internationalization process: Impact of competition and experience

The process, or evolution, through which multinational firms have reached their present international position is often referred to as “the internationalization process of the firm.” The most widely accepted theory of this phenomenon explains this slow, and sequential process in terms of organizations’ growth and learning. It is every now and then argued that this approach has lost some of its explanatory value. The purpose of this article is to discuss the validity of this model against the backdrop of assumptions in two key dimensions, namely, firms’ experience of international business and the industry's degree of internationalization.     

Investments in consumer relationships: a critical reassessment and model extension

This study is a critical reassessment and extension of De Wulf et al.'s (2001) framework investigating retail investments in consumer relationships. Their initial model relates four types of relationship marketing efforts to perceived relationship investment, in turn influencing relationship quality and ultimately behavioural loyalty. Based upon signalling theory, we extend this model by introducing product and service efforts as additional antecedents. Moreover, in contrast to the use of self-reported measures in the initial model, we apply customer database information in order to measure the construct of behavioural loyalty. Based upon 187 consumers reporting on their relationship with a Belgian apparel retailer, the SEM results provide guidelines for retailers how to increase the quality of their relationships with consumers by strengthening consumers' perceptions of relationship investment.
