Punishment strategies in repeated games: Evidence from experimental markets

An experiment is designed to provide a snapshot of the strategies used by players in a repeated price competition game with a random continuation rule. One hundred pairs of subjects played the game over the Internet, with subjects having a few days to make their decisions in each round. Occasionally subjects are asked to enter one-period-ahead pricing strategies instead of prices. According to the elicited strategies, between 90% and 95% of subjects punish less harshly (in their initial response to a deviation) than implied by the grim trigger strategy, and do so in a way that depends on the size of the other subjectʼs deviation. Future earnings are highest for subjects adopting the tit-for-tat strategy, even after controlling for a subjectʼs past earnings. Punishment strategies are generally softer and more graduated than implied by a grim trigger strategy, and do better as a result.

时代与政治洪流里中国现代作家另种样本的解读——评常勤毅《从“共时”到“横跨”——骆宾基:中国现当代作家中的一个抽样分析》

常勤毅的《从“共时”到“横跨”—骆宾基:中国现当代作家中的一个抽样分析》将骆宾基放在中国现当代文学的宏观层次上,通过研究这一“个案”来评析三十年代抗日作家尤其是东北作家群扣四十年代国统区进步的民主主义作家及其新中国成立后一度陷入创作困境的老作家的共性,进而试图在与骆宾基既有联系又有区别的许多中国现当代作家的比较下,总结出中国现当代文学发展的历史经验教训,为今后中国文学的进一步繁荣积累宝贵的经验.该书主旨明确、史论结合,紧紧扣住“同步”、“共时”与“横跨”这三个关键词.全书持论公允,论述充分,文笔清新、流畅.是本有思想、有特色、有启迪的著作.

Auction fever: Rising revenue in second-price auction formats

The prevalent term “auction fever” visualizes that ascending auctions – inconsistent with theory – are likely to provoke higher bids than one-shot auctions. To explore and isolate causes of auction fever experimentally, we design four different strategy-proof auction formats and order these according to expected rising bids based on pseudo-endowment effect arguments (psychological ownership and disparity between willingness to pay and willingness to accept). Observed revenues in the experiment in the four formats rank as expected if bidders have private uncertain values (the private information of a bidder is the distribution of her value). A control treatment supports our view that the traditional private certain values approach prevents auction fever in the laboratory. Another control treatment with a procurement auction relates the auction fever bids to bids in a one-shot auction with real endowments. We conclude that, when bidders are uncertain about their valuations, auctions that foster pseudo-endowment may raise bids and revenues.

Mapping the consumer‐subject in advertising

Traditionally marketing communication‐or more specifically advertising‐has been framed in terms of products/ services, needs and wants of consumers as if these were real givens, existing independently of the forms and acts of marketing communication itself. From this perspective, advertising is merely seen as a purveyor of information about products/services/needs between producers and consumers but hardly as actively implicated in shaping, not only the relation between the processes of production and those of consumption, but also the conception of the consumer‐subject. This paper makes a brief diachronic account of advertising with a view to highlighting how the consumer‐subject is represented. Whereas early advertising conceives of the consumer‐subject as a “rational” decision‐maker, aware of its needs and desire, more recent advertising constitutes the consumer‐subject in a hyperreal, dream‐like world, which seduces and spellbinds it.
