Die neoklassische Theorie basiert auf dem Modell des homo oeconomicus, der eigennützig und rational handelt. Hinzu kommt die stillschweigende Annahme der unbegrenzten Wil-lenskraft, d.h. dass einmal gefällte Entscheidungen auch in die Tat umgesetzt werden. Zahl-reiche empirische Studien haben gezeigt, dass die Annahmen der neoklassischen Theorie in der Realität oft nicht zutreffen. Durch die Verhaltensökonomie wird in erster Linie die Ratio-nalitätsannahme hinterfragt. Daniel Kahneman unterscheidet zwei Denksysteme: einen schnellen, intuitiven Denkmodus (System 1) und einen langsamen, rationalen Denkmodus (System 2). Denkmodus 1 bedient sich kognitiver Faustregeln („heuristics“), die zu kognitiven Verzerrungen („biases“) führen können. Um die Entscheidungen der Individuen zu verbes-sern, schlagen Richard Thaler und Cass R. Sunstein vor, die Entscheidungsarchitektur („choice architecture“) der Individuen so zu gestalten, dass diese in...

In a first part, research trends in legal logic from the viewpoint of legal philosophy and artificial intelligence and law will be outlined. In particular, the following perspectives and challenges will be considered: (a) developing innovative logics and argumentation frameworks for modelling and representing legal interpretation and interpretive canons; (b) devising adequate and comprehensive logical models for understanding and reconstructing norm change mechanisms and legal dynamics; (c) studying the game-theoretic nature of argumentation in the law and identifying what game types can be used in general to model strategic legal dialogues; (d) combining deontic logics with other systems – e.g., action logics, epistemic logics, preference logics – to grasp legal concepts such as trust, responsibility, and influence. In a second...

The past decade has witnessed an amazing acceleration in the development of private international law legislation in China as well as a signicant progress in the quality thereof. In 2010, the Standing Committee of the National People’s Congress adopted China’s rst statute on private international law (Private International Law Act). The adoption of the Act is a historic event in Chinese legislative history, as it indicates that China has modernised its conflict of law rules after many years of unremitting eorts made by legislators and scholars. Moreover, the Supreme People’s Court of the PRC promulgated an Interpretation (I) of the Private International Law Act in 2013. The Interpretation (I) attempts to provide concrete explanations on the abstract articles mainly in Chapter...

Family law for a long time was only centred on one particular family unit: a man and a woman united in (indissoluble) marriage, and with children. But we now live in a world where marriages often end in divorce; where categories of gender are not as fixed as they used to be and legal men can give birth to children; where children are not necessarily genetically related to their birthparents or indeed may have three genetic parents, and even more social parents. The law has been too slow to react to societal changes and medical advances, and these issues need to be dealt with as a matter of urgency.
