The sociology of knowledge approach to discourse assumes that cultural knowledge—and thus cultural spaces—are generated and shared through discourse. Actors' shared perceptions of vulnerability and practices to create resilience should be interrelated with knowledge provided by the relevant...

This study introduces the urbanicity index of employment. Unlike traditional measures of urbanization (e.g., urbanization rate), the urbanicity index is distance-based and accounts for the scale aspect as well as the concentration aspect of urbanization. The concentration aspect can be...

Recently various exchange rate models capturing the dynamics during the transition from an exchange rate arrangement of floating rates into a currency union have been derived. Technically, these stochastic equilibrium models are diffusion processes which have to be estimated by discretely...

This paper deals with nonparametric inference for second order stochastic dominance of two random variables. If their distribution functions are unknown they have to be inferred from observed realizations. Thus, any results on stochastic dominance are in uenced by sampling errors. We establish...

The authors develop a dynamic approach to measuring the evolution of comparative brand premium, an important component of brand equity. A comparative brand premium is defined as the pairwise price difference between two products being identical in every respect but brand. The model is based on...

New and old products differ in two respects: quality and newness. Whereas a higher quality of a new product always benefits consumers, the newness itself benefits some consumers, but not others, and for some, it is even a disadvantage. We capture these features in a Hotelling model of Over-...

Industries necessarily differ with respect to their type of geographical concentration. When some industries are overrepresented in urban areas (urban concentration), then some other industries must be overrepresented in rural areas (rural concentration). Unfortunately, the existing measures of...

We present new empirical evidence on the distribution of earnings, income and wealth among entrepreneurs in Germany. We document that both earnings and income are more concentrated among entrepreneurs than among workers and describe a large-scale overlapping-generations model that can replicate...

When some industries are overrepresented in urban areas (urban concentration), some other industries must be overrepresented in rural areas (rural concentration). Existing measures of concentration do not distinguish between these different types of concentration. Instead, they rank industries...
