25 lat rynku sztuki w Polsce z perspektywy prawnika

2016

W artykule przedstawiono ewolucję prawnych ram polskiego rynku sztuki w latach 1989-2015. Pokazano główne problemy, z którymi przyszło się zmierzyć ustawodawcy oraz nakreślono możliwe kierunki rozwoju prawa rynku sztuki. Pierwotnie reguły dotyczące obrotu dobrami kultury niemal nie istniały, a rynek był słabo rozwinięty. Od tego czasu na rynku sztuki pojawili się nowi interesariusze i nowe problemy – od kwestii podatku od towarów i usług począwszy, przez ocenę autentyczności dzieła sztuki, na nielegalnym obrocie dziełami sztuki skończywszy.

Ricardo Madrazo. Un intermediario en el mercado de antigüedades

2019

Ricardo Federico Madrazo Garreta (1852-1917), fue un activo asesor e intermediario en el mercado del coleccionismo. Miembro del clan Madrazo y discípulo de su cuñado Mariano Fortuny, se relacionó desde joven con personajes destacados en el ambiente artístico e intelectual de la época. Profundizaremos en esta faceta del artista a través de las relaciones que mantuvo con coleccionistas como José Pascó, Archer Milton Huntington o la familia Havemeyer. Su correspondencia, consultada en diversas instituciones, nos servirá para reconstruir el funcionamiento del mercado de antigüedades desde una perspectiva más privada: un modus operandi que algunos coleccionistas utilizaban para conseguir mejores…

Colección Fortuny. Patrimonio textil en la subasta Drouot de 1875

2018

La colección de tejidos antiguos de Mariano Fortuny Marsal (1838-1874) salió a la venta en la subasta del Hôtel Drouot de París, pocos meses después de la temprana muerte del pintor. El estudio de varios catálogos manuscritos nos ha servido para conocer los precios y compradores de cada una de las referencias. Estos datos nos han permitido realizar un estudio comparativo entre diferentes categorías. Se ha realizado un análisis de la tipología de las piezas, según su valoración en el mercado, para establecer los aspectos que influyeron en la cotización de las mismas. The collection of antique fabrics of Mariano Fortuny Marsal (1838-1874) went on sale at the auction of the Hôtel Drouot in Par…

L'impact de l'information sur le résultat d'une vente aux enchères expérimentale de vin

2005

This paper reports the results of an experimental wine auction. Participants of the experiment were randomly assigned to three rooms. In each room four wines had to be evaluated, but the level of information to which participants had access differed across rooms. After the evaluations, the wines were sold sequentially, by four separate Vickrey auctions with secret reservation prices. We fi nd that certain socio-economic characteristics such as gender, income and consumption habits, have a signifi cant impact on the willingness to pay for wine, while others such as age and nationality, do not. We also fi nd that once individuals have read the label characteristics and extracts from wine guid…

What do we learn from comparing hedonic scores and willingness to pay data? [O8.2]

2010

Hedonic measurements are generally conducted in a blind condition and thus evaluate consumer reactions to the sensory characteristics of the products whereas auctions are generally conducted to determine consumer valuation of extrinsic characteristics. In the last 10 years these two approaches were combined to reveal consumer preferences. Thus, tasting was introduced in the auction procedures. However, only two papers reported a comparison of these two approaches (Lange et al., 2002 with a between-subject design and Noussair et al., 2004 with a within-subject design). The aim of this paper is to present such a comparison on four data sets collected in our laboratory for different food produ…

Revisiting the Salt Lake City Olympic scandal: Would the outcome be different today?

2016

Many international sport organizations face bribery scandals resulting from its event bidding process. The International Olympic Committee (IOC) faced this type of scandal with the 2002 Olympic Winter Games. Two members of the Salt Lake City Organizing Committee (SLOC) faced 15 criminal charges from providing more than US$1.2 million in cash and gifts to entice IOC members to support its bid. Ultimately both SLOC members were acquitted of all charges. Can a new interpretation of the United States’ anti-bribery law, the Foreign Corrupt Practices Act (FCPA), be effective in preventing similar sport scandals? peerReviewed

E-Fairs: a Cyber-Physical System for Aggregation and Economy of Scale in e-Commerce

2018

In recent years, the e-commerce arena has deeply changed because of the advent of new business models and the growing weight of huge global actors like Amazon. Some business models create competition between users, and the product price tends to rise (e.g., online auctions); other models, including group-buying, make users cooperate, and the price tends to go down. The present study extends the group-buying model and proposes a cyber-physical system called e-fair, in which both sellers and buyers are grouped to negotiate on a specific product or service. E-fairs minimize the global purchase price and the shipping resources respectively with the aggregation of demand and supply as well as or…

Energy efficient resource allocation in heterogeneous software defined network: A reverse combinatorial auction approach

2015

In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction game, which takes different quality of service (QoS) requirements into account. The heterogeneous network selection associated with power allocation problem is optimized by maximizing the energy efficiency of data transmission. By exploiting the properties of fractional programming, the resulting non-convex Winner Determination Problem (WDP) is transformed into an equivalent subtractive convex optimization problem. The proposed reverse combinatorial auction ga…

A Double Auction Mechanism for Virtual Resource Allocation in SDN-based Cellular Network

2016

The explosively growing demands for mobile traffic service bring both challenges and opportunities to wireless net- works, among which, wireless network virtualization is proposed as the main evolution towards 5G. In this paper, we first propose a Software Defined Network (SDN) based wireless virtualization architecture for enabling multi-flow transmission in order to save capital expenses (CapEx) and operation expenses (OpEx) significantly with multiple Infrastructures Providers (InPs) and multiple Mobile Virtual Network Operators (MVNOs). We for- mulate the virtual resource allocation problem with diverse QoS requirements as a social welfare maximization problem with transaction cost. Due…
