Bankruptcy, Counterparty Risk, and Contagion

This paper provides a unifying framework for the modeling ofvarious types of credit risks such as contagion effects. Weargue that Markov chains can efficiently be used to tackle theseproblems. However, our approach is not limited to pricing problemswith contagion. On the theoretical side, we derive pricing formulasfor three building blocks that are generalizations of contingentclaims studied in Lando (1998). These claims can be thoughtof as atoms forming the basis for all credit risk payments.Furthermore, we demonstrate that, in general, all contingentclaims exposed to credit risk satisfy a system of partial differentialequations. This is the key result to calculate prices of creditrisk claims explicitly and efficiently.     

Customer relationship management and company performance—the mediating role of new product performance

Customer Relationship Management (CRM) is widely accepted as an effective approach for collecting, analyzing, and translating valuable customer information into managerial action. However, the potential of CRM has been investigated only in the context of existing products. CRM’s potential to aid in future new product development (NPD) has been neglected. We develop a conceptual framework in which multiple facets of CRM are linked to new product and company performance. We test this model based on a cross-functional sample consisting of 115 R&D and 122 Marketing managers from firms spanning multiple industries. The results provide evidence that CRM has a positive effect on new product performance and further, that this effect is moderated by CRM reward systems but not CRM technology. We also show that new product performance mediates the relationship between CRM and company performance. These findings have important implications for research and practice in both the CRM and NPD areas.     

Asset allocation over the life cycle: How much do taxes matter?

We study the welfare effect of tax-optimizing portfolio decisions in a life cycle model with unspanned labor income and realization-based capital gain taxation. For realistic parameterizations of our model, certainty equivalent welfare gains from fully tax-optimized portfolio decisions are less than 2% of present financial wealth and lifetime income compared to a heuristic portfolio policy ignoring the taxation of profits (capital gains, interest and dividend payments). Compared to a heuristic portfolio policy that only ignores the realization-based feature of capital gain taxation and instead assumes mark-to-market taxation, these gains are less than 0.5%. That is, our work provides a justification for ignoring taxes in life cycle portfolio choice problems – a wide-spread assumption in that literature. However, if capital gains are forgiven at death (as in the U.S.), investors with strong bequest motives face substantial welfare costs when not tax-optimizing their portfolio decisions towards the end of the life cycle.     

Multinationals and plant exit: Evidence from Chile

This paper investigates three main questions: are affiliates of foreign multinationals more likely to exit than domestic firms? Does the exit probability of multinationals depend on its export orientation?, and Does the presence of multinationals affect the survival of other firms in the economy? Our results show that foreign plants are more likely to exit the economy, controlling for other firm and industry characteristics, only during the late 1990s, a period when the Chilean economy experience a massive slowdown. Our data also suggest that only domestic market oriented multinationals responded to this negative shock by being more “footloose”. We also find that the presence of multinationals has a positive effect on plant survival in the early 1990s. This positive effect, however, is fully captured by productivity, once controlling for TFP in our exit regressions we do not find any further impact of multinational presence on a plant's probability of exit.     

Wirksame Unterstützung: Strategische Kontrolle mit dem Analytic Hierarchy Process

Zusammenfassung  Die Zukunft ist ungewiss und wird von vielen Entscheidern unterschiedlich bewertet. Wie k?nnen wir zukünftige Entwicklungen für die t?gliche Arbeit in der Gesch?ftswelt handhabbar machen? Hilfen bietet ein Entscheidungsprozess, der die Analytic Hierarchy Process-Methode via Internet verwendet. Wie er genutzt werden kann, um Gesch?ftstrends der Zukunft im Hinblick auf heute f?llige Entscheidungen auszuwerten, zeigt ein Beispiel aus dem Schweizer Bankensektor.

Personenorientierte Medienrezeption: Ein Zwei-Ebenen-Modell parasozialer Interaktionen

Since its original formulation in 1956 by Horton and Wohl, the concept of parasocial interaction has received remarkable attention among communication scholars. However, it still suffers from a range of desiderata and lacks a coherent theoretical foundation that could guide empirical research. In this article, we present a two-level model of parasocial interaction (PSI) that is intended to lead to a better understanding of the processes of PSI. By refering to theories of media and social psychology, two levels are distinguished: «Low-Level-PSI» comprise the less intensive, superficial modes of media person perception whereas «High-Level-PSI» refer to intensive and elaborated forms of interpersonal involvement with a media character. Both levels are discussed in terms of cognitive, emotional and conative processes which characterize person-oriented media reception. Subsequently, media factors as well as individual characteristics are introduced which are likely to facilitate the intensity of PSI processes as reception is going on. The article concludes with a prospect about useful further developments of the two-level model as well as its implications for empirical audience and reception studies.     

Explaining Firms’ Export Behaviour: R&D,Spillovers and the Destination Market*

We examine the importance of a firm's own R&D activity and intra‐sectoral spillovers on the decision to export and the export intensity using firm level panel data for Spain for the period 1990–98. Own R&D activity is found to be an important determinant of export activity. There is little evidence to suggest that Spanish firms benefit from spillovers of the exporting activity of others. However, there is evidence that R&D spillovers exert positive effects on firms’ export ratios. We find a larger marginal impact of R&D spillovers on export intensity of firms exporting to other OECD countries than those exporting to non‐OECD nations.     

Poverty, voracity, and growth

This article investigates economic performance when enforceable property rights are missing and basic needs matter for consumption. It suggests a new view of the so-called voracity effect according to which windfall gains in productivity induce behavior that leads to lower economic growth. Taking into account that the rate of intertemporal substitution in consumption depends on the level of consumption, it is shown that “voracious behavior” is situation-specific. It occurs when an economy is in decline and sufficiently close to stagnation.     

Antecedents and consequences of effectuation and causation in the international new venture creation process

The selection of the entry mode in an international market is of key importance for the venture. A process-based perspective on entry mode selection can add to the International Business and International Entrepreneurship literature. Framing the international market entry as an entrepreneurial process, this paper analyzes the antecedents and consequences of causation and effectuation in the entry mode selection. For the analysis, regression-based techniques were used on a sample of 65 gazelles. The results indicate that experienced entrepreneurs tend to apply effectuation rather than causation, while uncertainty does not have a systematic influence. Entrepreneurs using causation-based international new venture creation processes tend to engage in export-type entry modes, while effectuation-based international new venture creation processes do not predetermine the entry mode.
