Traditionally, the scholarly journal market operates so that research institutions are charged high prices and the wider public is often excluded altogether, while authors can usually publish for free and commercial publishers enjoy high profits.  Two forms of open access regulation can...

Competition authorities all over the world worry that integration between search engines (mainly Google) and publishers could lead to abuses of dominant position.  In particular, one concern is that of own-content bias, meaning that Google would bias its rankings in favor of the publishers it...

Ultimatum games have been extensively used in experimental studies. By studying the consequences that restrictions shared by ultimatum games have in subject`s behaviour, this paper argues that some results are falsified by design constraints. This paper also presets a taxonomy of certification,...

We examine some of the factors that might influence the quality of information produced in discussion groups on the internet, such as USENET and the WELL. In particular, we look at the impact of various different pricing structures, and compare regimes in which anonymity is enforced with regimes...

Through an experiment this study investigates the effects that verification has on honest traders. This paper demonstrates that by reducing the scope for trust verification can have a negative effect on the behaviour of honest individuals. Specifically, the analysis shows that trustworthy agents...

This paper shows that a monopolistic certifying party can have incentives to disclose revealing information about the agent he is certifying. Using a three-person game-theoretic model and allowing certificate users (buyers) to have noisy estimates of the quality level of the agent being...

Models of macroeconomic learning are populated by agents who possess a great deal of knowledge of the "true" structure of the economy, and yet ignore the impact of their own learning on that structure; they may learn about an equilibrium, but they do not learn within it.  An alternative learning...

Many interactive environments can be represented as games, but they are so large and complex that individual players are in the dark about others' actions and the payoff structure.  This paper analyzes learning behavior in such 'black box' environments, where players' only source of information...
