Carsten Holtmann and Dirk Neumann Market and Firm – Two Sides of a Coin 1
No full textElectronic markets are not just evolving they are designed. As such providing electronic trading venues is an entrepreneurial activity. The institutional approach followed here introduces a market operator as an economic player. As the entrepreneur charges fees for his service of operating an electronic market, the transaction cost savings incurred by information technology are essentially fully shifted to the market participants. As such the momentum predicted by the Electronic Market Hypothesis is limited in practice. The paper addresses this gap by deriving a conceptual framework, which reconciles the classical view on electronic markets with the entrepreneurial view.

No full textBernhard Ralla, Christoph Holtmann, Gerd GeerlingDepartment of Ophthalmology, University of Düsseldorf, Düsseldorf, GermanyIt is with great interest that we read the publication by Kanellopoulos.1 In this the author shows in a group of 21 patients with 46 months of mean follow-up that the new CXL protocol described, where higher fluence UV light is used with shorter exposure, appears to be a safe, comfortable and effective treatment for stabilizing a progressive keratoconus. This is a very valuable observation. The author also concludes, that collagen cross linking may be a promising adjunct treatment in cases, where a risk of post-LASIK-keratectasia is suspected. LASIK for correction of keratectasia is still controversially discussed. If used as a prophylactic treatment to prevent post-LASIK keratectasia, we would like to point out that the cross linking should be performed preferably after the LASIK procedure because the first will impact various steps of the refractive laser treatment.View original paper by Kanellopoulos
