Martin Janíčko
Acta Oeconomica Pragensia 2012, 20(6):18-33 | DOI: 10.18267/j.aop.385
Financial innovations should be regarded as a substantial element in the functioning of modern economies and financial sectors. However, their general impact is to be assessed from the present perspective, essentially depending on their particular behaviour and the role they play in the economy.

Generally, the difference between the concepts lies in the approach to the issue of respecting or not respecting the duty of loyalty within corporate groups. Under certain conditions, German law enables a parent company to promote interests of the whole group at the expense of a subsidiary. It creates a system of specific rules in order to comprehensively regulate such interferences of the...
