<p class="0abstract">With the increasing relevance of mobile apps for companies, push notifications to address app users are also becoming more important. While the acceptance factors of push notifications have already been extensively researched, the effect of the different design elements on user interaction by opening the mobile app is still completely unexplored. Based on existing scientific findings from related fields, especially banner advertising and e-mail marketing, the authors first develop hypotheses on the effect of title, button and image on user interaction with push notifications. In several experiments the hypotheses are tested using the example of a mobile shopping app. The results are evaluated using Chi-square test and Cramer's V. While the use of a title seems to have a positive effect on interaction rates, the hypotheses on the positive effect of buttons and images on interaction rates have to be rejected.</p>

This essay aims at connecting the findings of Greenwood and Scharfstein, authors of “The Growth of Finance”, and my research topic "quantification of regulatory risk and impact of new regulation on business models”. The exercise focuses on how developments in the financial subsectors credit intermediation and asset management, for which a sound regulatory framework is needed, can be connected to prudential regulation. Prudential regulation, i.e. capital and liquidity regulation, primarily mitigates the weaknesses of the financial sector, which are pointed out by Greenwood and Scharfstein. Understanding the implications of prudential regulation, including societally beneficial as well as negative aspects, is the key aspect of the proposed dissertation topic. The outcome of this exercise with regards to the research agenda is that aspects such as financial macroeconomics , welfare considerations, and consumer protection issues might be worth adding.
