Understanding Customer Value in Business-to-Business Relationships

Abstract: Although literature emphasizes the importance of creating value for the customer in business-to-business marketing, our understanding of this concept is limited. Against this background, this paper examines the antecedents of customer value within the context of business-to-business relationships. In a departure from previous conceptualizations of value, the paper introduces the concept of core benefits and add-on benefits as well as purchasing price, acquisition costs, and operations costs to the business-to-business marketing literature. The impact of product, relational, and supplier characteristics on the perceived benefits and sacrifices are examined. Results from a survey of 981 purchasing managers across multiple manufacturing product categories in the United States and in Germany provide support for the hypotheses proposed in this paper. Managerial implications and directions for future research are identified following a discussion of the results.

Die Definition der Situation und die variable Rationalität der Akteure. Ein allgemeines Modell des Handelns

Abstract: Im Beitrag wird ein allgemeines Modell des Handelns auf der Basis von Hartmut Essers Frame-Selektionstheorie entwickelt, das die zentralen Einwande gegen die bisherigen Formalisierungen der Theorie uberwindet. Das Modell erklart, welche Definition der Situation ein Akteur vornimmt (Frame-Selektion), welches Programm des Handelns er heranzieht (Skript-Selektion) und welches Handeln er auszufuhren versucht (Handlungsselektion). Ausgehend von der Annahme, dass die Rationalitat der Akteure variabel ist, wird zudem angegeben, unter welchen Bedingungen ein Akteur bewusst diejenige Alternative wahlt, die seinen subjektiv erwarteten Nutzen maximiert (reflexiv-kalkulierender Modus), und wann er im Gegensatz dazu unhinterfragt eine mental stark zugangliche Alternative selegiert (automatisch-spontaner Modus). Auf diese Weise wird versucht, soziologische, okonomische und sozialpsychologische Handlungskonzepte in einer allgemeinen und gleichzeitig formal prazisen Theorie des Handelns zu integrieren.

Inequality Trends for Germany in the Last Two Decades: A Tale of Two Countries

Abstract: In this paper we first document inequality trends in wages, hours worked, earnings, consumption, and wealth for Germany from the last twenty years. We generally find that inequality was relatively stable in West Germany until the German unification (which happened politically in 1990 and in our data in 1991), and then trended upwards for wages and market incomes, especially after about 1998. Disposable income and consumption, on the other hand, display only a modest increase in inequality over the same period. These trends occured against the backdrop of lower trend growth of earnings, incomes and consumption in the 1990s relative to the 1980s. In the second part of the paper we further analyze the differences between East and West Germans in terms of the evolution of levels and inequality of wages, income, and consumption.
