The paper uses micro cross-section data from the GfK consumer panel for econometric demand analysis of private households in Germany. Contrary to most research which considered "average" behavior we extend this approach to consumer behavior for different "intensities" of consumption. Our...

This paper examines the role of habit persistence in consumption in explaining persistent responses of inflation and output to money growth shocks. A monetary stochastic dynamic general equilibrium (DGE) model with a money-in-the-utility-function (MIU-) setup is augmented by habit formation in...

The paper presents an extended version of the consumer choice problem. Different from the standard model, prices are not fixed but arise from Walrasian interactions of total demand and a stylized supply function for each of the goods. Three different types of evolutionary algorithms are set up...

We estimate the interaction between fixed and mobile usage both for voice and data services using consumer level data from April 2013 to March 2014 in a European country. We find a signi cant proportion of fixed voice consumption could be substituted by mobile voice, and vice versa. However, a...

This study realizes the benefits of optical fiber broadband as an economic stimulation thus it analyzes the determinants of optical fiber share in total broadband connections in OECD countries with the focus on the demand-driven factors and the government roles as the stimulator, the regulator...

There is widespread evidence that some firms use false advertising to overstate the value of their products. Using a model in which a policymaker is able to punish such false claims, we characterize a natural equilibrium in which false advertising actively influences rational buyers. We analyze...

The following paper discusses the social marketing campaign 'Drink milk. Grow to be great!'. This is the successful Polish health campaign which promotes milk drinking among Polish children. At the very beginning the case of Polish campaign is briefly presented in order to facilitate theoretical...

We combine spatial and monopolistic competition to study market interactions between downtown retailers and an outlying shopping mall. Consumers shop at either marketplace or at both, and buy each variety in volume. The market solution stems from the interplay between the market expansion...

This study introduces a monthly coincident indicator for consumption in Germany based on Google Trends data on web search activity. In real-time nowcasting experiments the indicator outperforms common survey-based indicators in predicting consumption. Unlike those indicators, it provides...
