It is increasingly observable that in different industries competitors jointly acquire and share customer data. We propose a modified Hotelling model with two-dimensional consumer heterogeneity to analyze the incentives for such agreements and their welfare implications. In our model the...

We introduce three types of consumer recognition: identity recognition, asymmetric preference recognition, and symmetric preference recognition. We characterize price equilibria and compare profits, consumer surplus, and total welfare. Asymmetric preference recognition enhances profits compared...

Bislang waren das Internet und die mobile Kommunikationstechnik weitgehend getrennte Bereiche. Es gibt allerdings immer mehr Ansätze, aus beiden Elementen neue Angebote für Unternehmen und Haushalte zu entwickeln, die zusammenfassend als M-Commerce (mobile commerce) bezeichnet werden. Die...

This paper presents a method for visualizing competitive market structures based on scanner panel date where asymmetries are taken into account. For this, I combined consumer choice models based on mixed logit models with three-mode principal component analysis. This approach can be used to...

Comparing groups with respect to hypothetical constructs requires that the measurement models are equal across groups. Otherwise conclusions drawn from the observed indicators regarding differences at the latent level (mean differences, differences in the structural relations) might be severly...

The forecasting of time series in goods management systems causes various problems that we identify and indicate possible solutions. The implementation of auxiliary information like promotional activities or calendar effects in forecasts using ARMA models and exponential smoothing methods may be...

In this paper we use 4 different time series models to forecast sales in a goods management system. We use a variety of forecast combining techniques and measure the forecast quality by applying symmetric and asymmetric forecast quality measures. Simple, rank-, and criteria-based combining...

With commodity prices continuing to decrease and with policy constraint that farmers cannot easily increase their incomes by increasing volumes of production, they must find alternative ways to maintain their standard of living. This can be achieved by either niche marketing of agricultural...
