Home-field advantage or a matter of ambiguity aversion? Local bias among German individual investors

This paper investigates whether familiarity induced by ambiguity aversion can help explaining the local bias phenomenon among individual investors. Using geographic closeness as a proxy for investor familiarity, we find that investors pull out of (unfamiliar) remote stocks and pour into (familiar) local stocks during times of increased market uncertainty. Moreover, the magnitude of this ‘flight to familiarity’ increases in the spread of an investor's ambiguity (about expected returns) between local and remote stocks. Our results prove robust to a number of alternative explanations of local bias. Specifically, we rule out a ‘home-field advantage’, where investors are able to translate information advantages about nearby companies into excess returns on their local stockholdings. We conclude that individual investors’ local bias is induced by ambiguity aversion in the portfolio selection process rather than a trading strategy based on superior information about local companies.     

Sectoral Heterogeneity in New Service Development: An Exploratory Study of Service Types and Success Factors

The service industry is of fundamental relevance for the economies of industrialized countries, as the service industry produces the highest growth in the gross domestic product. In this regard, new service development (NSD) represents a critical resource for competitive survival and a decisive factor of growth in the service industry. However, service firms across many industries are increasingly faced with the challenge of determining how best to manage their development of new service offerings. Although researchers have shown growing interest in NSD issues, this area is still underutilized. Furthermore, although the heterogeneity of the service industry has been emphasized for years, the current body of research on NSD mainly focuses on specific service environments, providing data that are often not comparable across different service sectors. Additionally, there is no study to date that comprehensively examines innovation activities and the relevance of service innovations’ success factors within different service industries. The aim of this exploratory study is to establish a more balanced picture of the nature of innovation activities in terms of NSD characteristics and success factors in the heterogeneous service industry. From this perspective, this paper begins with an examination of the factors that contribute to the success of NSD. Based on a meta‐analysis of new service success factor studies, 17 different success determinants are classified and aggregated to service‐related success determinants. Subsequently, a cluster analysis of 1016 service companies is used to identify different service innovation types. For the service sector, four service innovation types are determined: efficient developers, innovative developers, interactive adopters, and standardized adopters. Furthermore, based on interviews with service innovation managers, the previously identified success factors are examined for each innovation type using a standardized survey. Finally, based on the results of this exploratory study, the paper concludes with recommendations for NSD management and research propositions for each service innovation type. These propositions support innovation managers to successfully manage service innovations for the innovation type they are operating in.     

Interne Unternehmensberatungen

Ziel des vorliegenden Beitrags ist der Versuch, eine erste Systematisierung sowie eine Erweiterung und Aktualisierung der bestehenden Forschung über Formen sowie Funktionen Interner Unternehmensberatungen zu leisten. Auf Basis einer begriffsgeschichtlichen Ann?herung und der Rekonstruktion der wissenschaftlichen Beratungsforschung werden Ergebnisse einer empirischen Analyse eines kleinen Samples von Internen Beratungen vorgestellt. Vor dem Hintergrund dieses Datenmaterials formulieren die Autoren im zweiten Teil Thesen über aktuelle und potentielle Positionierungsszenarien von Internen Unternehmensberatungen. Hierbei steht insbesondere der Vergleich zu Externen Beratungen im Vordergrund.     

Wertorientiertes Dialogmarketing: Kampagnencontrolling auf dem Prüfstand

Zusammenfassung  Der wertorientierte Ansatz der Unternehmensführung gewinnt immer mehr an Bedeutung; damit w?chst auch der Rechtfertigungsdruck für Aufwendungen des Dialogmarketing. Um den Ansprüchen der Wertorientierung Rechnung tragen zu k?nnen, muss das Dialogmarketingcontrolling neu ausgerichtet werden. In diesem Beitrag lesen Sie, wie ein Analyse- und Gestaltungsrahmen für ein wertorientiertes Dialogmarketing aussehen und wie Wertorientierung im Dialogmarketingmanagement erfolgen kann.

Voluntary Environmental Agreements: Taking Up Positions And Meeting Pressure

This paper portrays voluntary agreements as a Nash-bargaining game between the authorities and the polluting industry. Before bargaining starts, the authorities threaten to introduce emission licences if the negotiations come to nothing, while industry, by the use of lobbying campaigns, can make it politically costly to regulate by law. The most likely game of the ones considered is characterized by the authorities first announcing a level of licensing, whereupon industry will adjust its lobbying activity. This game results in a relatively defensive industry and authorities than other games under consideration.     

Dynamic Costs of the Draft

Abstract. We propose a dynamic general‐equilibrium model with human capital accumulation to evaluate the economic consequences of compulsory services (such as military draft or social work). Our analysis identifies a so far ignored dynamic cost arising from distortions in time allocation over the life cycle. We provide conservative estimates for the excess burden that arises when the government relies on forced labor rather than on income taxation to finance public expenditures. Our results suggest that eliminating the draft could produce considerable dynamic gains, both in terms of GDP and lifetime utility.     

International Commodity Taxation under Monopolistic Competition

We analyze non‐cooperative commodity taxation in a two‐country trade model characterized by monopolistic competition and international firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes in the rents accruing to capital owners. With consumption‐based taxation, these fiscal externalities exactly offset each other and the non‐cooperative tax equilibrium is Pareto efficient. With production‐based taxation, however, there are additional externalities on the foreign tax base and the foreign price level that lead non‐cooperative tax rates to exceed their Pareto efficient levels.
