Flexibilisierung des Schutzgebietsnetzes Natura 2000 vor dem Hintergrund des Klimawandels

Das Thema Klimawandel und Naturschutz geh?rt derzeit zu den zentralen Gegenst?nden der politischen und wissenschaftlichen Umweltdiskussion. Sowohl für Juristen als auch für Naturwissenschaftler verschiedener Fachrichtungen stellt das Thema eine besondere Herausforderung dar. In den folgenden Er?rterungen geht es vor allem um die Fragen, welches Instrumentarium das geltende europ?ische Recht zum Schutzgebietsnetz Natura 2000 bereith?lt, um klimabedingten Arealverschiebungen von Tier- und Pflanzenarten Rechnung tragen zu k?nnen, und wie dieses Instrumentarium de lege ferenda optimiert werden kann. Die Bearbeitung der Fragen erfolgt auf der Grundlage rechts- und naturwissenschaftlicher Kooperation.     

Estimating damages from price-fixing: the value of transaction data

We use a unique private data set of about 340,000 invoice positions from 36 smaller and larger customers of German cement producers to study the value of such transaction data for an estimation of cartel damages. In particular, we investigate, first, how structural break analysis can be used to identify the exact end of the cartel agreement and, second, how an application of before-and-after approaches to estimate the price overcharge can benefit from such rich data sets. We conclude that transaction data allows such a detailed assessment of the cartel and its impact on direct customers that its regular application in private antitrust cases is desired as long as data collection and preparation procedures are not prohibitively expensive.     

A proposal for cadaver organ procurement: routine removal with right of informed refusal

In order to alleviate the shortage of vital organs for transplant, we propose a system of routine removal of cadaver organs with an option of informed refusal by family. Unless an individual registered an objection during his or her lifetime, or unless the family objected to the procedure, clinicians would be permitted routinely to salvage vital organs for transplant. Our proposal charts a middle path between the current ineffective policy based on "encouraged voluntarism" and "presumed consent" policies that promise effectiveness at the cost of violating traditional ethical and legal principles. In this article, we analyze the failure of the current regime, articulate a policy of routine removal subject to the right of informed refusal, and defend this policy against several possible objections.
