A note on reverse auctions

Reverse auctions are a new type of auction which has recently spread over the internet to sell a large variety of goods, from electronics to airline tickets. The objective of this note is to illustrate how a reverse auction works, compare it to the other existing auctions and discuss the legal issues that may arise.

Entomotoxicology, experimental set-up and interpretation for forensic toxicologists

Forensic entomotoxicology studies the usefulness of insects as alternative toxicological samples. Use of insects as alternative matrix for drug detection is well documented and recommended when conventional matrices such as blood, urine or internal organs are no longer available. However, several limitations of entomotoxicology have been highlighted, especially concerning interpretation of the drug concentrations in insects on human forensic cases. In addition, the lack of knowledge in pharmacokinetic of drugs in insects, large variability of experimental set-up and toxicological analysis compromise the utility of this science. This review focuses on the current knowledge of factors influencing drug detection in insects. Reasons for the current limitations, but also recommendations for future research are discussed and proposed in this paper.     

The role of information asymmetry in the market for university–industry research collaboration

This study concerns the market for research collaboration between industry and universities. It presents an analysis of the population of all Italian university–industry collaborations that resulted in at least one international scientific publication between 2001 and 2003. Using spatial and bibliometric analysis relating to scientific output of university researchers, the study shows the importance of geographic proximity in companies’ choices of university partner. The analysis also reveals inefficiency in the market: in a large proportion of cases private companies could have chosen more qualified research partners in universities located closer to the place of business.     

The simple economics of class action: private provision of club and public goods

This article uses economic categories to show how the reorganisation of civil procedure in the case of class action is not merely aimed at providing a more efficient litigation technology, as hierarchies (and company law) might do for other productive activities, but that it also serves to create a well defined economic organization ultimately aimed at producing a set of goods, first and foremost among which are justice and efficiency. Class action has the potential to recreate, in the judicial domain, the same effects that individual interests and motivations, governed by the perfect competition paradigm, bring to the market. Moreover, through economic analysis it is possible to rediscover not only the productive function of this legal machinery, but also that partial compensation of victims and large profits for the class counsel, far from being a side-effect, are actually a necessary condition for reallocation of the costs and risks associated with the legal action.
