Die Analyse von online vermitteltem Tausch, insbesondere derjenige bei Onlineauktionen, erfreut sich einiger Beliebtheit. Dafür gibt es neben der ökonomischen Bedeutung dieser Tauschform auch soziologische Gründe. Inzwischen zeigt eine beträchtliche Anzahl von Untersuchungen, dass online vermittelte Transaktionen durch ein Reputationssystem stabilisiert werden können. Dabei bewerten sich die beiden Transaktionspartner nach erfolgtem Tausch gegenseitig mittels eines von der Auktionsplattform bereitgestellten Bewertungssystems. Beide Tauschpartner haben die Möglichkeit, eine negative Bewertung mit einer ebensolchen zu vergelten, bzw. im Vorgriff darauf mit Vergeltung zu drohen, falls eine negative Bewertung erfolgen sollte. Es besteht hier also ein Kollektivgutproblem zweiter Ordnung, dessen Lösung Bedingung für eine stabile Gütertransaktion ist. In diesem Aufsatz wird analysiert, wie diese Stabilisierung theoretisch geschehen kann und welche empirischen Belege sich dafür anführen lassen. Dazu wird im nächsten Abschnitt vorerst der gesamte Tauschvorgang als ein zweifaches Vertrauensspiel modelliert und zwei einschlägige Lösungsansätze in Hypothesenform präsentiert. Dabei wird einmal von vollständig rationalen Akteuren und einmal von reziprok rationalen Akteuren ausgegangen. Die generierten Hypothesen werden anschließend anhand eines selbst erhobenen Datensatzes überprüft. Dieser enthält Angaben zu insgesamt 1800 Transaktionen und entsprechend 3600 potentiellen Bewertungen, die über eBay Deutschland getätigt wurden. Dabei wird neben der Analyse der Standardbewertungen insbesondere eine Analyse der dazugehörigen Freitextkommentare vorgenommen. Im vierten Abschnitt werden die Resultate theoretisch diskutiert und es wird auf der Basis der empirischen Ergebnisse zur Handlungsmotivation der Bewertenden ein Vorschlag gemacht, mit welchen institutionellen Maßnahmen der Bewertungsmechanismus verbessert werden könnte.

In this dissertation auction formats are developed and discussed that focus on three specific economic environments. Regarding the impossibility results from mechanism design, the main task for the implementation of auction designs is to balance allocative efficiency and incentive compatibility – the main characteristics a mechanism should provide. Therefore, the dissertation investigates the limits of conceivable relaxations of allocative efficiency and incentive compatibility for complex settings such as double auctions, interdependent-valuation environments and electricity market designs. The overall aim is to carefully weigh up the advantages and disadvantages for either relaxing allocative efficiency or respectively incentive compatibility.:Preface … 7 1. Introduction … 8 1.1.

The illicit trade with cultural property is a worldwide problem. Many of the cultural properties that are traded have been plundered and exported from countries and end up on western markets, often at auction houses and auction platforms online.  This study aims to understand the responsibility Swedish auction houses and online platforms have regarding the illicit trade with cultural properties. This is achieved by answering the following questions: what responsibility does the auction houses and online platforms have? Do they take this responsibility? Do auction houses and online platforms have policy documents regarding cultural objects? What do these policy documents in that case look like and can they be improved? Is there a difference between the policy documents of physical auction houses and auction platforms online?  To answer these questions this study focuses on three main areas of sources: document analysis of legal and policy documents, previous research and articles published in the field, as well as five qualitative and semi-struc- tured interviews. These sources are discussed throughout the analysis which have been divided thematically. An overview of the trade in Sweden culminates in a discussion about due diligence and provenance. Further, a discus- sion of the auction houses responsibilities and policy documents is followed by chapters discussing the same ques- tions in regard to the online platforms.  Conclusions which have been drawn from the empirical analysis are that the auction businesses take respon- sibility to a certain degree but that policy documents and the transparency in public discourses can be improved. Furthermore, they should be clear that they use due diligence and actually make sure that they do it in their daily activities.  This is a two-year master’s thesis in Museum and Cultural Heritage Studies.

This also confirms that it is a profitable business model with market potential. / Trabajo de investigación

This dissertation attempts to provide a comprehensive examination on the non-market valuation of the effect of open space amenities and local public infrastructure on the value of urban land and housing with both spatial heterogeneity and project heterogeneity. The demand for raw land is a derived demand for housing built on it. Therefore, we need to examine the land market and the housing market together. On the one hand, we estimate the value of urban land in a market that does not satisfy the usual assumptions of a competitive market structure as well as incentive incompatibility issues for transaction participants, with an application to a Chinese regional wholesale land market. These two violations to the traditional hedonic theory also generate two separate valuations on land with differentiated characteristics. On the other hand, we utilize the relative plane coordinates system, the three-dimensional distances, as well as the aggregate weight matrix, to implement the spatial hedonic estimation on the high-rise residential buildings in the same regional housing retail market in China. After these two steps, this dissertation, therefore, focuses on the profit maximization behavior of the property developer, which is the key role to link the factor market (i.e., the land market) and the commodity market (i.e., the housing market) together. Two methods are then employed to implement the hypothesis test on the hedonic price estimation including both inputs and outputs. First, a set of partial derivatives of the profit function with respect to various characteristics gives us the relationship between the marginal valuations in the land market and in the housing market. Second, we introduce a joint estimation approach that we call the spatial full information maximum likelihood (SFIML), which considers the land market, the housing market, and the property developer's profit maximization behavior all together in the estimation. Finally, we conduct a hypothesis test in both of these two scenarios to examine the validity of our linked markets assumption on the hedonic price estimation.

While Machine Learning is one of the most popular research areas in Computer Science, there are still only a few deployed applications intended for use by the general public. We have developed an exemplary application that can be directly applied to eBay trading. Our system predicts how much an item would sell for on eBay based on that item's attributes. We ran our experiments on the eBay laptop category, with prior trades used as training data. The system implements a feature-weighted k-Nearest Neighbor algorithm, using genetic algorithms to determine feature weights. Our results demonstrate an average prediction error of 16%; we have also shown that this application greatly reduces the time a reseller would need to spend on trading activities, since the bulk of market research is now done automatically with the help of the learned model.
