| Abstract: | In this study we use an information-processing perspective to explore the impact of response scales on respondents answers in a web survey. This paper has four innovations compared to the existing literature: research is based on a different mode of administration (web), we use an open-ended format as a benchmark, four different question types are used, and the study is conducted on a representative sample of the population. We find strong effects of response scales. Questions requiring estimation strategies are more affected by the choice of response format than questions in which direct recall is used. Respondents with a low need for cognition and respondents with a low need to form opinions are more affected by the response categories than respondents with a high need for cognition and a high need to evaluate. The sensitivity to contextual clues is also significantly related to gender, age and education |

| Abstract: | We study optimal pricing in the presence of recommender systems. A recommender system affects the market in two ways: (i) it creates value by reducing product uncertainty for the customers and hence (ii) its recommendations can be offered as add-ons which generate informational externalities. The quality of the recommendation add-on is endogenously determined by sales. We investigate the impact of these factors on the optimal pricing by a seller with a recommender system against a competitive fringe without such a system. If the recommender system is sufficiently effective in reducing uncertainty, then the seller prices otherwise symmetric products differently to have some products experienced more aggressively. Moreover, the seller segments the market so that customers with more inflexible tastes pay higher prices to get better recommendations. |

| Abstract: | In a series of previous papers different aspects of the regional price behavior of wheat on the French market were investigated. The derived results, presented in Borghers [1, 2, 3, 4 and 5], are based on aggregated as well as disaggregated data and are covering the last decades of the Ancien Régime, i.e. the period 1756-1790, and the period immediately following the French revolution, i.e. the period 1806-1872. One of the main and recurrent results from these analyses is the consistent, regular but changing regional patterns in the price behavior of wheat. Furthermore these findings seem to be independent from the specific statistical techniques and measures used in the analysis. It is evident that the nature of these regularities are a great help in better understanding the internal structure of the French wheat market throughout the periods under investigation. The main purpose of this paper is to investigate whether or not these regional differences could be ‘explained’ by the geographical distance between these regions. In other words the relationship between the wheat price fluctuations in different markets will be analyzed with respect to the distance between those markets. The basic hypothesis is that the wheat price relationship, measured by the correlation coefficient, will decrease as a function of the growing distance. The dependency of the correlation on distance is known as correlation length. In this respect the correlation length can be seen as an important measure of the level of market integration. This paper is following a simple structure. In Section 2 some preliminary information will be given about the geographical locations used in the analysis. Once these locations are defined the geographical distances can be derived. An analysis of these distances will be the subject of Section 3. In Section 4 and Section 5 different aspects about the correlation length will be discussed in detail. In the final Section 6 the summarized results will be confronted with some results found in the literature. |

| Abstract: | When we address the topic of ethical issues on the Internet we are generally referring at two different matters: privacy and intellectual property. Each has been examined extensively in the last five years, since the Internet explosive intrusion in everyday life activities, each has an important number of sub fields that require special attention from managers and other business professionals. The purpose of this paper is to make a short presentation of most relevant developments pertaining Internet ethical issues in direct connection with the business world. |

| Abstract: | In this paper, we analyze the equilibrium on the market for schooling where both public and private schools coexist and where individuals are differentiated by income and ability. We study the distribution of students across sectors while examining the conditions for the existence of a majority voting equilibrium in the context of non single peaked preferences. Finally, we examine the existence of a hierarchy of school qualities, as a consequence of the discriminating pricing strategy used by private schools to internalize the effect of peer groups. |
