Der Dioxin-Skandal bei Futtermitteln, aber auch die fehlerhafte und interessengeleitete Beratung beim Kauf von Finanzdienstleistungen hat die Verbraucherpolitik in Misskredit gebracht. In der öffentlichen Debatte werden zunehmend rigidere Vorschriften für die Anbieter gefordert, aber auch mehr...

The 2002 prices of suppliers in German call-by-call telephone market are rather dispersed, out-of-phase (uncorrelated), and show systematic down-up movements. In 2004, these prices are less dispersed, more in-phase and show more upwards runs than downs-ups. In both years, we clearly do not...

We characterize a monopolist's optimal offer of service plans when only informed customers know already at the contracting stage whether their demand is high or low, while uninformed customers may learn their demand only after incurring some costs, if at all. While informed customers purchase...

The EU appliance energy consumption labeling scheme is a key component of efforts to increase the diffusion of energy-efficient household appliances. In this paper, the determinants of consumer knowledge of the energy label for house-hold appliances and the choice of class-A energy-efficient...

Electronic commerce and flexible manufacturing allow personalization of initially standardized products at low cost. Will customers provide the information necessary for personalization? Assuming that a consumer can control the amount of information revealed, we analyze how his decision...

If a product has two dimensions of quality, one observable and one not, a firm can use observable quality as a signal of unobservable quality. The correlation between consumers' valuation of high quality in each dimension is a key determinant of the feasibility of such signaling. A firm may use...

Most of the empirical literature on consumption behaviour over the last decades has focused on estimating Euler equations. However, there is now consensus that data-related problems make this approach unfruitful, especially for answering policy relevant issues. Alternatively, many papers have...

This paper studies the consumption decisions of agents who face costs of acquiring, absorbing and processing information. These consumers rationally choose to only sporadically update their information and re-compute their optimal consumption plans. In between updating dates, they remain...
