Variety in the video game industry: An empirical study of the Wundt curve

This study analyzes the effect of variety on consumer utility using historical behavioral information for 1,397 consumers participating in 729,049 unique rounds of play. We show that consumers generally exhibit a preference for variety as part of their gameplay utility. The relationship between variety and utility is nonlinear and follows, at least for some types of variety, an inverted u‐shape as predicted by the Wundt curve. Our results represent the first such evidence on the importance of variety in video gaming, which has significant implications for consumption through optimization of gameplay utility to satisfy the demand for variety.     

ECONOMIC TRANSITION AND LABOUR MARKET DYNAMICS IN CHINA: AN INTERPRETATIVE SURVEY OF THE ‘TURNING POINT’ DEBATE

Has the Chinese economy approached the ‘Lewisian turning point’ that marks the ending of the initial phase of industrial transformation fuelled by surplus labour? In this paper we undertake an interpretative survey of the literature on this issue, in the context of China's labour market conditions prior to the reforms and structural change of the past three decades. The available evidence is mixed, and our assessment makes a strong case for probing institutional constraints to labour mobility from an economy‐wide perspective, going beyond the confines of the rural economy.

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.     

Prudent expectations equilibrium in economies with uncertain delivery

In an economy with private information, we introduce the notion of objects of choice as lists of bundles out of which the market selects one for delivery. This leads to an extension of the model of Arrow–Debreu that is used to study trade ex ante with private state verification. Under the assumption that agents are prudent, equilibrium is characterized by the fact that agents consume bundles with the same utility in states that they do not distinguish. This is a weaker condition than the restriction of equal consumption imposed by Radner (Econometrica 36(1), 31–58, 1968), therefore, some no trade situations are avoided and the efficiency of trade increases.     

Libraries in transition to a marketing orientation: are librarians' attitudes a barrier?

• This study examines librarians' attitudes toward the marketing of library services, as libraries continue their transition to a marketing orientation. Although prior studies had observed misunderstandings and hostility to marketing among librarians, most previous discussions of this topic were either speculative or based on extremely small samples. In order to provide more evidence in this matter, a large‐scale survey of members of the New Jersey Library Association (NJLA) was conducted. A ‘Pro Marketing’ scale was introduced and used to segment participants with respect to their attitudes. The findings indicate that most respondents expressed relatively positive attitudes toward marketing, but that more positive attitudes were expressed by public librarians than school or college/university librarians, and by administrators as opposed to reference and technical services librarians. Illustrative respondent comments and implications for library management are included.

Breaking Collusion in Auctions through Speculation: An Experiment on CO2 Emission Permit Markets

The European Emission Trading Scheme (EU‐ETS) has chosen to adopt an auctioning procedure to initially allocate CO₂ emission permits. Free allocation of permits will become an exception for the third phase (2013–2020) and most firms will have to buy all their permits on the market or via auctions. The ability of bidders to collude is a key concern about the design of the auction format. To counter collusion, the auction can be open to bidders without compliance obligations (speculators). This paper aims at studying experimentally speculation as a collusion‐breaking device in two different auction mechanisms: the uniform‐price sealed‐bid auction and the ascending clock auction. Our results suggest that a uniform sealed‐bid auction open to speculators should be chosen from a revenue maximization point of view. In this mechanism, compliance agents adopt an aggressive strategy toward speculators. This strategy significantly increases the seller's revenue, compared to the more collusive clock auction. In the latter, on the contrary, bidders accommodate speculators, letting them buy permits in the auction and buying their necessary permits on the secondary market. However, as opening the auction to speculators deteriorates efficiency, the regulator faces a trade‐off between these two objectives.     

LGBT Neighbourhoods and ‘New Mobilities’: Towards Understanding Transformations in Sexual and Gendered Urban Landscapes

In this article we apply insights from ‘new mobilities’ approaches to understand the shifting sexual and gendered landscapes of major cities in the global North. The empirical context is the purported ‘demise’ of traditional gay villages in Toronto, Canada and Sydney, Australia, and the emergence of ‘LGBT neighbourhoods’ elsewhere in the inner city. We reinterpret the historical geography of twentieth century LGBT lives and the associated ‘rise and fall’ of gay enclaves through the lens of the ‘politics of mobility’. In this reading, it is apparent that multifaceted movements — migration, physical and social mobility, and motility — underpin the formation of gay enclaves and recent transformations in sexual and gendered landscapes. After the second world war, LGBT communities in the global North were embedded in specific historical geographies of mobility and we trace these in the Canadian and Australian contexts. The ‘great gay migration’ from the 1960s to the 1980s has been joined by new LGBT constellations of mobility in the 2000s, and these have imprinted upon the sexual and gendered landscapes of Toronto and Sydney.     

Política de la legislación laboral en el sur de China. Las cámaras de comercio y otros organismos extranjeros ante las leyes sobre negociación colectiva

En 2010, tras la huelga en Honda, hubo protestas laborales en toda China. Los gobiernos de Shenzhen y Guangdong reaccionaron desempolvando los proyectos de Decreto sobre consulta colectiva y de Normativa sobre gestión democrática de las empresas, retirados con anterioridad. Pero tras la oposición frontal de cámaras de comercio y organismos gubernamentales extranjeros, hongkoneses y taiwaneses, volvieron a retirarse. Mediante entrevistas, los autores revelan los medios de influencia en la legislación laboral china de estos actores, cuyas actitudes dependen de la posición de las empresas representadas en las cadenas mundiales de producción y del modelo de relaciones laborales de su país o territorio de origen.
